Select the correct Yarn count for Double Lacoste fabric:

In my this post I will introduce you with some equations, with which we can select the actual yarn count for knit the fabric. These are vary for fabric types.

Double Lacoste 

Say, the require GSM is 220

Yarn count  = (-0.167) X (GSM) + 64.36

                   = (-0.167) X (220) + 64.36

                   = -36.74 + 64.36

                   = 27.62

So, to knit 220 gsm Double Lacoste fabric we need yarn count 27.62/s

Thanks & best regards
