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.
