How can select the actual yarn count for required GSM?

Select the correct Yarn count for required GSM:

In my post I would like to share with you some equations, which we can select the actual yarn count for knit the fabric. These are varying for fabric types.

Also note, Spinner does not make Odd no. yarn count. That’s why all yarn count should be Even No. like as- 18/S, 20/S, 22/S, 24/S, 26/S…………. etc. 

Single Jersey 

Say, the require GSM is 220

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

                   = (-0.141) X (220) + 50.22

                   = -31.02 + 50.22

                   = 19.2

So, to knit 220 GSM Single Jersey fabrics we need yarn count 20/s

Pique 

Say, the require GSM is 220

Yarn count = (-0.146) X (GSM) + 57.16

                   = (-0.146) X (220) + 57.16

                   = -32.12 + 57.16

                   = 25.04

So, to knit 220 GSM Pique fabric we need yarn count 36/s

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 fabrics we need yarn count 28/s

Interlock 

Say, the require GSM is 220

Yarn count = (-0.206) X (GSM) + 80.56

                   = (-0.206) X (220) + 80.56

                   = -45.32 + 80.56

                   = 35.24

So, to knit 220 GSM Interlock fabrics we need yarn count 36/s

1*1 Rib 

Say, the require GSM is 220

Yarn count = (-0.123) X (GSM) + 54.57

                   = (-0.123) X (220) + 54.57

                   = -27.06 + 54.57

                   = 27.51

So, to knit 220 GSM 1x1 Rib fabrics we need yarn count 28/s

Lycra 2x2 Rib 

Say, the require GSM is 220

Yarn count = (-0.108) X (GSM) + 56.62

                   = (-0.108) X (220) + 56.62

                   = -23.76 + 56.62

                   = 32.86

So, to knit 220 GSM Lycra 2x2 Rib fabrics we need yarn count 32/s
