Calculate G.S.M of Woven fabric from its Construction:

G.S.M = (EPI/warp count + PPI/Weft count) x (100+crimp %) X 0.2327

Examples:

 Suppose,

Construction of a 100% cotton poplin fabric is 40s X 40s / 133 X 72 (here, EPI=133 & PPI=72) and warps and weft crimp is 6%.

Then G.S.M of this fabric will be …..

G.S.M = (133/40 + 72/40) X (100+6%) X 0.2327

=> G.S.M =126.414

N.B Here 0.2327 is multiplying factor for G.S.M

But someone use this formula with different multiplying factors like …….

G.S.M= ((EPI/warp count X 1.1) + (PPI/weft count x 1.04)) x 23.5
Where 1.1 and 1.04 are warp and weft crimp factors respectively.
