Different Types of Twill Weave

Twill weave is a kind of weave that repeat on three or more ends and picks and produces diagonal line on the face of fabric.In a regular twill the diagonal line or twill line produces at 45 degree angle with the horizontal.

Twill weave is second basic weave from the production and using point it view, it is also in second position .Mainly the fabric painting are made it the structure. Example ,Denim fabric (3/1) made it twill weave.

Feature of Twill Weave:
The main feature of twill weave are mention bellow:-
  1. Diagonal line can be seen on the faced of the fabric.
  2. Twill line may be from lower lift to upper right(Z-twill) or from lower right to upper lift(S-twill) corner.
  3. Smaller repeat twill is(3)It means take at least end and three picks produce twill weave.
  4. Three or more heald shaft are required for shedding.
  5. Generally straight draft is used for twill weave besides this pointed or v draft is also used.
  6. Appearance it will design can be seen from both rides the fabric.
  7. Diagonal lines run at angle vary between(15-75)Degree but in a continuous or regular twill is 45 degree.
Twill Angle:
Twill angle is the angle which is produced by twill line with respect to the horizontal line.This twill angle depends on following factors.
  1. Ratio between EPI and PPI.
  2. Difference between warp and weft count.
  3. Rate of advancement it interlacement warp and weft. 
Classification of Twill Weave:
Twill weave is can classified various ways they are mention below,

1. According to direction of twill line on the faced of fabric.

2. According this aspect there are two type of twill weave namely.
  • S -twill:Down word displacement of twill line from upper left to lower right corner.
  • Z- twill:Upword displacement of twill line from lower left to upper right corner.
3. According to faced yarn:there are three type of twill weave according to faced yarn namely:-
  • Warp faced twill:For example twill.
  • Weft faced twill:For example twill.
  • Balenced twill:For example twill.
4. According to nature and twill line:There are thre type of twill weaves,
  • Sample warp or weft twill: It every warp thread passes under only one weft called simple warp twill.For example , twill are simple are warp twill again it every weft thread passes over only one warp thread in twill weave,that is called simple weft twill.For example,, twill are simple weft twill.
  • Expended twill: There is no one up or one down in this type of twill.For example,, twill
  • Multiple twill:If in a fabric there are more than one twill line in the repeat,it is called multiple twill.
Factor Affecting the Prominence of Twill Weave:
The following factor affecting the prominence of twill weave

1. Feature of weave
The prominence of twill line on feature of weave in the following ways;
  • The twill of short floats less prominent twill line.
  • The twill line of long float more prominent.
2. Characteristic of yarn:
It influence twill line as bellow:
  • Twill off course and soft twisted yarn→ More prominent twill line.
  • Twill of fine and more twisted yarn→ Less prominent twill line.
3. Thread per inch(TPI): More number of ends or picks per inch causes more prominent twill line.

4. Direction of twill line in relation to yarn twist direction:
When direction of twill on fabric is opposite to the direction of twist in yarn the twill line becomes more prominent and vice-versa.

Derivatives of Twill Weave: 
There are many derivatives of twill are given bellow;
  1. Broken twill.
  2. Combined twill.
  3.   Diamonddesign.
  4. Diaper design.
  5. Diagonal design.
  6. Elongated design.
  7. Hearing bone twill.
  8. Shaded twill.
  9. Stepped twill.
  10. Zigzag/waved/pointed twill weave.
Zigzag/waved/pointed Twill Weave:
It is the simplest and one of the most important modifications of twill weave produced by reversing the direction of twill at suitable interval

A point is sellected(usually the last warp is sellected) as the reversing point and so it is sometime call as point twill.In this twill pointed or straight draft is used.

This twill is produced by combining S and Z twist. According to reversing of direction there are two type of zigzag twill:
  1. Horizontal zigzag twill.
  2. Vertical zigzag twill.
1. Horizontal zigzag twill: When the reversal direction of twill line occur upon the warp yarn,it result a horizontal zigzag twill,Here the basic twill is extended in warp direction.Here the number of warp yarn in a repeat is double of the number of weft.In horizontal zigzag twill pointed draft is used.
Horizontal zigzag twill
2. Vertical zigzag twill: When the reversal direction of twill line occur upon the weft yarn,it result a vertical zigzag twill,Here the basic twill is extended in weft direction.Here the number of weft yarn in a repeat is double of the number of warp.In Vertical zigzag twill straight draft is used.
Vertical zigzag twill
Hearing Bone Twill:
This twill are constracted in a different manner from the ordinary zigzag twill.Though it also depend on reversal of twill direction

Here reversal direction occurs after a middle line.Here at first the basic twill is drown then the number of central point is selected in zigzag twill.Rather in exdended second half of basic twill the following matter happened.
  • The floating point of first half become down in second half.
  • The down of first half become floating in second half.
In hearing bone twill straight draft is used.There are two type of hearing bone design
  1. Horizontal hearing bone twill.
  2. Vertical hearing bone twill.
Horizontal hearing bone twill: When hearing bone twill is created by extending the basic twill in warp direction,horizontal hearing bone result in
Horizontal hearing bone twill
Vertical hearing bone twill: When hearing bone twill is created by extending the basic twill in weft direction,horizontal hearing bone result in
Vertical hearing bone twill
Diamond Design: 
It is a derivatives of twill weave.It constructed on the bans of zigzag twill principle.It is obtain by combining a horizontal and vertical zigzag twill.So here in the repeat the number of both warp and weft thread are double then that in basic twill.

Dimond design geometrical about there vertical and horizontal axis.In this weave pointed draft is obtained.
Diamond design
To contract a diamond design at first the design repeat is selected.It the basic twill is 3 up 3 down,that is 6×6 insize,the repeat of design will be 12×12 insize.

Uses: Towel, Bed cover, Table cloth, Pillow cover etc.

Diaper Design:  
This derivative of twill weave is created on the basis herring bone principle. This design is constructed by combining horizontal and vertical hearing bone twill.
Diaper Design
In the repeat of a diaper design the number of warp and weft threads are two type more than that in its basic twill. So if the basic twill size is 8×8.Its diaper design repeat size will 16×16. In case of diaper design, Broken or straight draft is used

Use: Same diamond.

Broken Twill:
This is obtain by breaking the twill line of a reguler twill It is somewhat similer in appearance Zigzag twill

Broken twill can be obtained in different ways.At first basic twill is divided into two section then the first section unchanged and the second section is reverse ii its order,that is to say if the basic twill is made up of 8 warp threads namely1,2,3,4,5,6,7,8 then its broken twill derivatives will obtain the order 1,2,3,48.7,6,5
Broken twill
Broken twill can be of way and ioncrease of broken twill straight and Broken draft is used.

Elongated Twill:
The twill angle from in cloth depend upon,
  1. The relative ratio of ends and pick per unit length.
  2. The rate of advancement of one interlacing with respect to the following one.
Normally the twill angle is 45 degree where the end and pick per unit area are equal.But in elongated twill,the twill angle more or less than 45 degree any twill design without twill angle.

Elongated twill can be formed in two different ways:

(a)With the help of step number.
(b)By sellecting stasting of elongated twill with a base line.

(a)With the help of step number:
If the step number of elongated twill is two, then by taking only odd numer of warp thread from the basic twill here the warp number in step twill will be equal to the basic twill.
With the help of step number
(b) By sellecting stasting of elongated twill with a base line:
Here at first a step number is to be selected. In such a way that the repeat of base line become divisable by that step number.
Elongated twill
For example,for a twill with formulla number the repeat size will be 14×14.If we sellect move number as 2 then in produced elongated twill the number number of warp thread will be 7 and that of weft thread will be 7 in case of weft faced twill.

Steppet twill: Steppet twill is produced by stepping a continious twill.This are two type steppet twill,

(a)Warp way steppet twill.
Warp way steppet twill
(b)Weft way steppet twill.
  • Warp way steppet twill:Here stepping is done in warp way.
  • Weft way steppet twill:Here stepping is done in weft way.
Shaded Twill:
By shaded twill we can create shade effect on fabric the shade effect is created by the combination some thick to thin twills or thin to thick twills.

The shaded twill are of following type,

Single shaded twill: Here the shade effect become thick form thin once after being thick it again starttng to be thin and thus complet the whole repeat.For example
Single shaded twill
Double shaded twill: Here the shade starts form thin to thik and again it become thin.for example,

Uses of Twill Weave:

Twill weave are extensively used in manufacturing cloth for garments household cloth and industrial cloth.
  1. Generally dimond,diaper and zigzag twill are used for making pillow,cover,screen,unpholstery,bed sheet,towel etc.
  2. Continious twill are used for making fabric for shirting,suiting and pantin(denim,gaverdine).
  3. For making various type of ornamental cloth,other derivatives of twill weave are used.
  4. Hearing bone twill are used in the cloth of suiting and overcoats.

Determination the Count of a Given Cotton Fabric by Beasley Balance

Theory:
Yarn count: The yarn count is a numerical expression which defines its fineness or coarseness. It also expresses weather the yarn is thick or thin. A definition is given by the textile institute – “Count is a number which indicates the mass per unit length or the length per unit mass of yarn.”

To determine the count of the yarn we use five instruments with wrap reel & analytical balance. Beesley balance is one of them. It is working on the principle of fixed weight and fixed length system

Objectives of Experiment:
  • To know about yarn count.
  • To know about template & beesley balance.
  • To know how to determine the count by template & beesley balance.
Required Instrument:
  1. Template
  2. Beesleys Balance
  3. Knife
  4. Marking pen
  5. Needle
Template:
Template is a length measuring instrument which contains eight arms. When a sample has short length (Fabric) which we cannot determine by the wrap reel then we use template by using that we can determine the length .
Fig: Beesley balance
The following length is used to determine the count:
  • Cotton : 4.32 Inch
  • ½ cotton :2.16 Inch
  • Linen :1.543 Inch
  • Wool :1.315 Inch
  • Worsted :2.88 Inch
Beesleys Balance:
Beesleys yarn balance consists of a pillar A which carries a cross beam B, fulcrumed at knife edge at the point G. At one end the cross beam is a hook E upon which the yarn to be tested can be placed. The other end of the beam tappers to a point C. When the beam is in balance, the pointer will coincide with the detum line .The pillar is mounted on the base. The whole instrument is leveled by a leveled screw at one end of the base. The cross has a small notch at the point D to take the counter weight or rider

Data Collection:

Result: The cotton sample fabric warp yarn count is 30s

Procedure:
  1. Collect sample by appropriate sampling method.
  2. This Sample conditioning at testing atmosphere.
  3. Marked the fabric by using template
  4. Cut that’s fabric by knife according to the marking.
  5. The pointer is set directly opposite to the detum line, with no material and counter weight in their proper places, by adjusting the leveling screw. The counter weight for the particular length which is supplied with the instrument is chosen and suspended at the notch D. (For full cotton the large rider is placed in the notch and for ½ cotton small rider is placed)
  6. Now yarn is withdrawn from sample and placed sample hook until the pointer comes in level with the detum line.
  7. At that stage the threads are taken out and counted which givers directly the cont of yarn teken for testing.
  8. There 30 threads in the sample hook at the balanced condition so the count of the yarn is 30s
Precaution:
  1. We should yarn withdrawn from fabric very carefully.
  2. Marked fabric very carefully.
Conclusion: 
It is the very easy process but if we cannot use template properly according to yarn type and idle weight than the result will be faulty.

Eco Fabric: 14 Strange and Amazing Textile Innovations

Relying on polluting textile materials like cotton and polyester may become a thing of the past as a new range of eco-fabrics emerge, often made from materials that would otherwise go to waste. Some of these environmentally friendly fabrics are already in use, like those made of coconut husks, recycled plastic bottles, wood pulp and corn, while others are strange and futuristic, sourced from hagfish slime, fermented wine, spoiled milk and genetically engineered bacteria.

Fabric from Fermented Wine

A group of scientists at the University of Western Australia has produced fabric by letting microbes go to work on wine. The scientists culture bacteria called Acetobacter in vats of cheap red wine, and the bacteria ferments the alcohol into fibers that float just above the surface. These fibers can be extracted and fashioned into clothing. The only catch? Acetobacter produce vinegar as its end product, so the garments have a definite odor.

Naoron, Durable Fabric Made of Wood Pulp

This leather alternative is not only animal-friendly, it also eschews the chemicals required to create conventional faux leather. Naoran is a water-resistant textile derived from wood pulp and recycled polyester. It’s soft, flexible, and tear- and water-resistant.

Hagfish Slime Thread

The slimy substance in the photo above is defensive goo attached to a hagfish, an eel-shaped bottom-dwelling animal of the deep seas that is the only known creature to have a skull, but no vertebral column. Scientists have discovered that proteins within this slime have mechanical properties rivaling those of spider silk, and can be woven into high-performance bio-materials.

Electroluminescent Garments

For this unusual fabric in a collection by fashion designer Vega Wang, silk was printed with images of constellations and other space-related themes, and then the fabric was lined with electroluminescent paper. Programmed controllers enable the paper to shine through the silk for a dreamy, ethereal effect.

Spider Silk Made from Metabolically Engineered Bacteria

Known for its tremendous strength – three times stronger than both steel and Kevlar, yet thinner than a human hair – spider silk is a highly valuable material for textiles. But farming and harvesting spider silk is a definite challenge. Instead, geneticists have found a way to chemically synthesize the silk gene and insert it into E. coli bacteria.

Ingeo, Fabric Made from Corn


Synthetic fibers are most often petroleum-based, but recycled fibers and those sourced from natural substances are on the rise. Ingeo, a fabric by Natureworks derived from fermented corn starches, can be spun into fibers for apparel and home textiles, and also used for bio-plastics.

Silk-Like Fiber Derived from Spoiled Milk

Few of us would willingly walk around wearing spoiled milk, but it might just become all the rage in the near future. A company called Qmilch makes fabric from protein found in soured ‘secondary milk’ that’s no longer suitable for human consumption, and would normally be thrown away. This zero-waste fabric requires no harmful chemicals to make, and uses less water in the production process than other milk-based fabrics.

Newlife Polyester Yarn Made of Recycled Plastic Bottles

Newlife is a polyester yarn made from 100% post-consumer recycled plastic bottles, which is processed by mechanical rather than chemical means. Made in Italy, the fabric is used in fashion, sportswear, underwear, medical garments and other clothes and furnishings. Georgio Armani used it to create a fashionable, eco-friendly gown for LIvia Firth at the 2012 Golden Globe Awards.

Used Coffee Pods

Inspired by the resourcefulness of locals in Kerala, India, who repurpose waste in surprising ways, designer Rachel Rodwell discovered a material that wasn’t living up to its potential: used coffee pods. Rodwell gathers pods from friends and family and smashes them with a meat tenderizer, reconfiguring them into geometric-inspired designs in colors that reflect India’s cultural aesthetics.

Recycled Newspaper Yarn

Artist Ivano Vitali tears recycled newsprint into strips and twists it into balls of yarn without the use of glue, dyes or silicone, crocheting them into textile art with custom-made wooden knitting needles and hooks as long as 8 feet. Recently, Vitali has expanded into wearable art, achieving certain colors for dresses, jackets and even bikinis by painstakingly sorting his printed materials by color.

Self-Repairing Textile

Once a protective garment like a raincoat or lab wear is ripped or torn, it’s useless. But the total loss of these garments may become a thing of the past with the creation of ‘intelligent’ fabric that can heal itself. Researchers at SINTEF added microcapsules containing a glue-like substance to the plastic polyurethane that is applied to modern rainwear, so that if the garment snags, the capsules release a sealant that fills in the gaps and hardens with contact to air and water.

Cocona, Made of Coconut Husks

It was only a matter of time before tough, fibrous coconut husks were made into durable fabric. Cocona is one trademarked example, made of coconut-husk waste disposed of by the food service industry. The fabric is lightweight and breathable, making it ideal for sportswear. It’s used in Nau’s insular jacket.

Lab-Grown Biological Textiles

How will biotechnology change the fashion industry? Designer Amy Congdon believes that in the future, we’ll be able to grow textiles like ethical fur in laboratories. Her series ‘Biological Atelier’ imagines a workshop, circa 2082, where high-fashion garments are grown from cells.

Recycled Cassette Tapes

All of the strands of cassette tape still floating around in the world could not only be reused for fabrics, but spun into ‘audio textiles’ that play back under a tape head. Artist Alyce Santoro weaves this unlikely material on antique looms in a family-run textile mill in England to produce ‘Sonic Fabric’, including purses made from sound collages based on life in New York City.

10 Facts About Fabric

I absolutely adore fabric!  Whether silk, or satin, damask or linen,  it adds so much to a room; it creates a feel; it is part of history….fabric is so interesting! And it is never to be overlooked when designing or decorating a space.

Here are some interesting facts about fabric that I think are cool and even useful!
fabric-flax.jpg1)  Flax is the earliest known natural textile fabric seen used in about 5000 BC. Flax is the material used to make linen which is seeing a huge come back today in drapery and upholstery.

2)  There is evidence that cotton and wool were used to create natural fabrics in about 3000 BC and evidence of silk use in 2500 BC in China.

3)  China is still the largest maker and exporter of silk in the world and has been for 100’s of years.

4)  The earliest evidence of fabric textiles has been found in Turkey, Egypt and Israel.

5)  The creation of man-made fibers has only been within the last 100 years.  Rayon, was the first man-made fiber created in 1910 and it was called ‘artificial silk’. Viscose is the most common form of Rayon.

6)  Microfiber or Ultrasuede was invented over 20 years ago in Japan.  Microfiber is the thinnest of all man-made fibres, even finer than silk.  it is 100 times finer than a human hair.

7)  Acrylic is a man-made fiber that has a soft, wool-like hand, is machine washable and has excellent color retention.  It is often an additive to textiles to take advantage of these properties.

fabric-nylon.jpg8)
  Nylon is also man-made and was first produced in 1938.  It has high strength, excellent resilience and superior abrasion resistance.  Nylon replaced silk stockings for women in the early part of the 20th century.

9)  The highest quality cotton still comes from Egypt.
10)  Bamboo is a grass that has been used to create a fabric that hangs much like a heavy linen.  Interestingly it has natural wicking ability that pulls moisture away from the skin so it can be useful in reducing moisture related or dour.  It also has natural anti-bacterial qualities.  And it is sustainable as bamboo grows quickly and doesn’t need pesticides to thrive.

Apparel Manufacturing Process

Steps involved in garment manufacturing process

Ready to wear apparel or garment manufacturing involves many processing steps, beginning with the idea or design concept and ending with a finished product. Apparel manufacturing process involves Product Design, Fabric Selection and Inspection, Pattern making, Grading, Marking, Spreading, Cutting, Bundling, Sewing, Pressing or Folding, Finishing and Detailing, Dyeing and Washing, QC etc.



  1. Receiving Fabrics

    Garment factories receive fabric from overseas textile manufacturers in large bolts with cardboard or plastic center tubes or in piles or bags. The fabric typically arrives in steel commercial shipping containers and is unloaded with a forklift. Garment factories often have a warehouse or dedicated area to store fabric between arrival and manufacturing.
  2. Fabric Relaxing

    fabric relaxing
    “Relaxing” refers to the process that allows the material to relax and contract prior to being manufactured. This step is necessary because the material is continually under tension throughout the various stages of the textile manufacturing process, including weaving, dyeing, and other finishing processes. The relaxing process allows fabrics to shrink so that further shrinkage during customer use is minimized.
    Garment manufacturers perform the relaxing process either manually or mechanically. Manual fabric relaxing typically entails loading the bolt of fabric on a spinner and manually feeding the material through a piece of equipment that relieves tension in the fabric as it is pulled through. Mechanical fabric relaxing performs this same process in an automated manner.
    Many garment manufacturers will also integrate quality assurance into this process to ensure that the quality of the fabric meets customer standards. This step is performed by manually spot-checking each bolt of fabric using a backlit surface to identify manufacturing defects such as color inconsistency or flaws in the material. Fabrics that fail to meet customer standards are returned to the textile manufacturer.
  3. Spreading, Form Layout, and Cutting

    fabric spreading and cuttingAfter the fabric has been relaxed, it is transferred to the spreading and cutting area of the garment manufacturing facility. The fabric is first to cut into uniform plies and then spread either manually or using a computer-controlled system in preparation for the cutting process. The fabric is spread to:
    • allow operators to identify fabric defects;
    • control the tension and slack of the fabric during cutting; and
    • ensure each ply is accurately aligned on top of the others.
    The number of plies in each spread is dependent on the fabric type, spreading method, cutting equipment, and size of the garment order.
    Next, garment forms—or patterns—are laid out on top of the spread, either manually or programmed into an automated cutting system. Lastly, the fabric is cut to the shape of the garment forms using either manually operated cutting equipment or a computerized cutting system.
  4. Embroidery and Screen Printing

    embroideryEmbroidery and screen printing are two processes that occur only if directly specified by the customer; therefore, these processes are commonly subcontracted to off-site facilities. Embroidery is performed using automated equipment, often with many machines concurrently embroidering the same pattern on multiple garments. Each production line may include between 10 and 20 embroidery stations. Customers may request embroidery to put logos or other embellishments on garments.
    Screen printing is the process of applying paint-based graphics to fabric using presses and textile dryers. Specifically, screen printing involves sweeping a rubber blade across a porous screen, transferring ink through a stencil and onto the fabric. The screen printed pieces of fabric are then dried to set the ink. This process may have varying levels of automation or may largely be completed at manually operated stations. Like embroidery, screen printing is wholly determined by the customer and may be requested to put logos or other graphics on garments or to print brand and size information in place of affixing tags.
  5. Sewing

    sewingGarments are sewn in an assembly line, with the garment becoming complete as it progresses down the sewing line. Sewing machine operators receive a bundle of cut fabric and repeatedly sew the same portion of the garment, passing that completed portion to the next operator. For example, the first operator may sew the collar to the body of the garment and the next operator may sew a sleeve to the body. Quality assurance is performed at the end of the sewing line to ensure that the garment has been properly assembled and that no manufacturing defects exist. When needed, the garment will be reworked or mended at designated sewing stations. This labor-intensive process progressively transforms pieces of fabric into designer garments.
  6. Spot Cleaning and Laundry

    spot cleaning and laundryIn addition to identifying manufacturing defects, employees tasked with performing quality assurance are also looking for cosmetic flaws, stains, or other spots on the garment that may have occurred during the cutting and sewing processes. Spots are often marked with a sticker and taken to a spot-cleaning area where the garment is cleaned using steam, hot water, or chemical stain removers.
    Some customers request that a garment be fully laundered after it is sewn and assembled; therefore, garment factories often have on-site laundry or have subcontract agreements with off-site laundry operations. Commercial laundry facilities are equipped with at least three types of machines: washers, spinners, and dryers. Some facilities also have the capability to perform special treatments, such as stone- or acid-washing.
  7. Ironing

    ironingAfter a garment is fully sewn and assembled, it is transferred to the ironing section of the facility for final pressing. Each ironing station consists of an iron and an ironing platform. The irons are similar looking to residential models but have steam supplied by an on-site boiler. Workers control the steam with foot pedals and the steam is delivered via overhead hoses directly to the iron. In most facilities, the ironing platforms are equipped with a ventilation system that draws steam through the ironing table and exhausts it outside the factory.
  8. Packaging and Shipping

    packaging and shippingIn the last steps of making a product retail-ready, garments are folded, tagged, sized, and packaged according to customer specifications. Also, garments may be placed in protective plastic bags, either manually or using an automated system, to ensure that the material stays clean and pressed during shipping. Lastly, garments are placed in cardboard boxes and shipped to client distribution centers to eventually be sold in retail stores.

Textile Manufacturer: Job Description, Duties and Requirements

Textile manufacturers do not have any formal education requirements. Learn about the necessary experience, job duties and skill requirements to see if this is the right career for you.
Textile manufacturers are not required to have formal post secondary education to enter this field. Their specific duties may vary, depending on whether they work as a textile presser or a textile furnishings worker, or textile bleach and dye machine operator. Other employment options include being a textile winding machine setter, operator and tender, working with textile cutting machines, or being a production supervisor.

Essential Information

Textile manufacturers oversee the production of raw materials into salable textile products. Effective management and people skills are necessary for managing the many departments in a textile mill. Technical expertise in textile production is also required for plant managers. Formal education is typically not required for these positions, but a degree in product management or a similar field may provide career advancement opportunities.
Required EducationNo formal education required
Other RequirementsExperience working in various departments often necessary
Projected Job Growth (2014-2024)*-7% to -26%

Textile Manufacturer Job Description

The U.S. Bureau of Labor Statistics (BLS) states that textile manufacturers can work in three areas of the textile industry - in textile mills, textile production mills, and apparel manufacturing. Textile mills take raw textile materials, such as cotton and polyester, and produce them into fabric. Apparel manufacturers produce clothing and accessories from fabricated materials, and textile production mills manufacture goods other than clothing (www.bls.gov). The manufacturer is engaged in each production process and manages the workers and supervisors of each production department.

Job Duties of Textile Manufacturers

Textile manufacturers, or plant managers, are engaged in numerous duties throughout the work day. They generally oversee multiple departments in the textile mill, maximizing efficiency and productivity. They may be responsible for troubleshooting mechanical problems that hinder the flow of production. Overseeing the shipping of final products to meet shipment deadlines may be another duty. November 2010 job postings for textile plant managers surveyed on CareerBuilder.com include duties such as controlling inventory, managing budgets and implementing ways to improve quality.

Job Requirements

Management positions are usually earned through experience. Many textile manufacturers start their careers in production jobs and gain the broad experience needed by plant managers by working in various departments. Knowledge of production machinery and production methods is a job asset often earned by experience.
Higher education in textile-related fields is beneficial, though not always mandatory. According to the BLS, a bachelor's or master's degree in a product management or engineering field can open up advancement opportunities in the textile industry. In the South and Northeast regions of the country, some universities have specialized engineering programs that provide courses in textile technology, engineering and materials.

Career Info

The BLS reported salaries for several careers related to the textile manufacturing industry. Textile and garment pressers earned a median annual salary of $20,470 in May 2015. Textile, apparel and furnishings workers earned a median annual wage of $26,310; textile knitting and weaving machine setters, operators and tenders earned $27,220; and textile cutting machine setters, operators and tenders earned $25,490. Additionally, textile bleaching and dyeing machine operators and tenders earned a median annual wage of $26,340, while textile winding, twisting and drawing out machine setters, operators and tenders earned $26,870. In general, first-line supervisors and managers of production and operating workers in the textile earned a median annual income of $51,120 in 2015, per the BLS (www.bls.gov).
Textile manufacturers may operate equipment that's used to dye or cut textiles. These professionals can work at textile mills, textile production mills, or they may work for those who manufacture apparel. No formal training is needed for many production jobs, but a degree in textile engineering, product management or a similar field may be required for higher positions.

How to Find Yarn Count from GSM

Yarn Count from GSM:
If we want to job in garments then we need to know this things.

Like we need to make a single jersey Fabric. But we didn't know the fabric count. Some people say through experience like you can use 26/28 count of yarn. It’s depend on experience. But if you want to know perfectly then you need to know the tricks. Before going to tricks, we should know what is count and GSM? 

 
Definition of Yarn Count:
Yarn count is a numerical value which refers to the coarseness or fineness of the yarn. It is calculated by taking into account the length and weight of the yarn. The weight of the yarn is just the mass per unit length of the yarn.

Definition of Fabric GSM:
Fabric GSM refers to the Grams per Square Meter of the fabric. It is the weight of the fabric per square meter, measured in grams.

Example: Single jersey fabric is 130 GSM. Now find the yarn count?

Ans: For single jersey,

4300/GSM

= 4300/130

= 33.08

You can make this kind of fabric with 32/34 count of yarn.

Another System:

For single jersey,

(-0.141 x GSM) + 50.22

= (-0.141 x 130) + 50.22

= 31.89

So you can make fabric with 32 count of yarn.

I also add some others:

  1. Terry = 6240 ÷ GSM
  2. S/J = 4300 ÷ GSM
  3. Pique = 5200 ÷ GSM
  4. Fleece = 7200 ÷ GSM
  5. Interlock = 7200 ÷ GSM
  6. 1x1 Rib = 6000 ÷ GSM
  7. Lacost = 5500 ÷ GSM
  8. 2x2 Rib = 6250 ÷ GSM
  9. Terry = 6240 ÷ GSM
Another Tricks:
  1. S/J = (-0.141x GSM) +50.22
  2. Pique = (-0.146 x GSM) +57.16
  3. Double Lacost = (-0.167 x GSM) +64.36
  4. 1x1 Rib = (-0.123 x GSM) +54.57
  5. Interlock = (-0.206 x GSM) +80.56
  6. Lycra 1x1 Rib = (-0.119 x GSM) +59.12
  7. Lycra 2x2 Rib = (-0.108 x GSM) +56.62
