v Loom EPI :- Finish EPI (1-Weft Crimp%)
100
v Loom PPI :- Finish PPI (1-Warp Crimp%)
100
v Tape Length :- Cloth Length(1+Warp Crimp%)
100
v Reed Width :- Cloth Width(1+Weft Crimp%)
100
v Warp Weight :- 0.59*EPI*Reed Width*Tape Length
Warp Count
v Weft Weight :- 0.59*PPI*Reed Width*Cloth Width
100
Problem:
Q. To find the GSM of the fabric using following particular?
EPI = 110 PPI=90
Warp Crimp% = 8% Weft Crimp % = 2%
Warp Count = 2/40 Ne
Weft Count = 20Ne
Solution :-
1.
Warp Weight
:- 0.59*110*39.37*(1+8/100) = 138gm
20
2.
Weft Weight
:- 0.59*90*39.37*(1+2/100) = 106.61gm
20
Total Weight = Warp Weight +
Weft Weight
= 138+106.61 = 244gm
