Terry Towelling parameters for designing and production

Terry Towelling parameters for designing and production 

- Size of towel: Grey & Finish

- Dimentions of Hem, Terry Bar, Border and Body Of Towel

- Finish & Grey weight/GSM of towel

- Reed count ie warp density

- Weft density (Body & Border)

- No. of splits on loom

- Yarn used in warp(Pile & Ground),weft(Body Weft & Border Weft)

- Material used cotton /polyester(Pile, Ground & weft)

- Major count _2/20 k, 2/24 K, 1/10 OE, 1/14 OE, 1/16k etc.

- Tape length used in pile and ground

- Weight loss consideration during all process like shearing, washing,tumbling and dying etc.

- Production calculations by PCs and wt.

- Wastage parameter at various stage of manufacturing

- Pile Height

Terry Towel Calculations -1

Assumptions
Number of Ground Warp Ends = 694
Ground Warp Count = 25 tex x 2
Warp Crimp = 8%
Weft Yarn count = 34 tex
Number of Pile Warp Ends = 576
Length of pile part = 102 cm
Pile Ratio (for pile height)= 52:10 (52 cm of pile warp for 10 cm of cloth)
Pile Yarn count = 30 tex x 2
Length of plain part = 4 cm
Picks per cm = 20
Reed Width = 58.4 cm
Grey Length ( Pile and Plain Part) = 106 cm
Fringe Length = 2 cm

How to Determine the Weight of a ground Warp for Terry Towel

Weight of Ground Warp = Weight of ground warp in grey cloth + weight of ground warp in the fringe.

Weight of ground warp in grey cloth = (length of grey cloth x warp crimp factor x no of ground warp threads x warp yarn count in tex )/ (100 x 1000)
= (106 x 1.08 x 694 x 25 x 2)/(100 x 1000)
= 397.25 gms

Weight of Ground Warp in Fringe (here the warp crimp is not involved) = (Fringe length x no of ground warp x yarn count in tex)/ (100x 1000)
= (2 x 694 x 25 x 2)/ (100 x 1000) = 0.69 gms

So Ground Warp Weight = 397.25 +.69 = 397.94 grams.

How to Determine the Weight of Pile Warp in Terry Towel


Weight of Pile Warp = weight of pile warp in pile part + that in plain part + that in fringe

a. Weight of pile warp in pile part ( Pile ratio: 52:10)
=( Length of pile part x number of pile threads x pile length x yarn count in tex) / (100 x 1000)
= (102 x 576 x 52 x 30 x 2)/(100 x 1000)
= 183.31 g

b. Weight of Pile warp in Plain Part
=( Length of plain fabric x number of pile threads x crimp factor x yarn count)/ (100 x 1000)
= (4 x 576 x 1.08 x 30 x 2)/(100 x 1000)
= 1.49 g

c. Weight of Pile warp in fringe ( No crimp , no loop )
= (fringe length x number of pile threads x yarn count)/(100 x 1000)
= (2 x 576 x 30 x 2)/(100 x 1000)
= 0.69 g
Weight of pile warp = 183.31+ 1.49 + 0.69 = 185.49

How to Determine the Weight of Weft in Terry Towel

Weight of Weft Yarn

= (Total no of weft threads x reed width x yarn count)/(100 x 1000)
(Reed width is equal to the length of one weft yarn)
= (106 x 20 x 58.4 x 34)/(100 x 1000)
= 42.09 g
