GSM & GLM calculation of woven fabric


Construction:-

       12s OE * 12s OE - 64*44*63"
Where ,
   Warp = 12s OE
  Weft   =  12s OE
   EPI.   = 64
   PPI.   = 44
   WIDTH = 63"

Now,
   Warp GLM
         Total End = EPI * width
                           = 64  * 63
                           = 4032
GLM = Total end / ( warp count * 1.693)
         = 4032/ ( 12* 1.693)
         = 198.46
Add, Crimp % = 8%
As per fabric construction crimp % will be vary.
   So,
            = 198.46 + 8%
            = 214.33
Add, sizing % = 5%
            = 214.33 +  5%
            = 225.24
Wrap GLM = 225.24

Weft GLM
            = PPI * 39.37
            = 44* 39.37
            = 1732.28
            = 1732.28 * Width in m
            =  1732.28 * 63" * .0254
           =   2771.99

    GLM =  2771.99 / ( Weft count * 1.693)
               = 2771.99 / ( 12 * 1.693)
               = 136.44

Add, crimp % = 4%
        GML.  = 136.44 + 4%
                   = 141.89

Total fabric GLM ,
        Wrap GLM + Weft GLM
       = 225.24 + 141.89
       = 366.9

GSM ,
            Total fabric GLM / Width in m
         = 366.9 / 1.6002
        = 229
