How to Read Fabric Construction?


How to read fabric specification with the construction of 76 X 68 30/30 of 100% cotton composition?


In the tech-pack, the buyer gives details of the fabric specification for its construction and composition (fibre content). The specification is similar to the description mentioned above 76X68 30/30 and 100% Cotton composition

Fabric construction

Fabric construction with this description is read as the following:
76 X 68 is read as

Ends per inch are 76 and Pick per Inch is 68.  Or EPI X PPI = 76 X 68
This means that if you take a specimen of 1 inch X 1 inch of this fabric, you will find 76 number of warp yarns and 68 numbers of weft yarns.

If you don't the terms, Ends means Warp yarns and Picks means Weft or Filling yarns. 

30/30 defines yarn sizes used in the fabric.
Here warp yarn size is 30's Ne and weft yarn size is 30's Ne. Both warp and weft yarns are single ply. 

100% Cotton: Fabric composition. Fabric is made of 100% cotton fibre.

You might also find another form of fabric construction like
  1. 30X30 / 76X68 (Here yarns count are mentioned first and then EPI X PPI is mentioned)
