Select the correct Yarn count for single jersey 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.

Single Jersey 

Say, the require GSM is 160

Yarn count  = (-0.141) X (GSM) + 50.22

                   = (-0.141) X (160) + 50.22

                   = -22.58 + 50.22

                   = 27.66

So, to knit 160 gsm single jersey fabric we need yarn count 27.66/s
