In 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.
Select the correct Yarn count for single jersey fabric:
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
Select the correct Yarn count for Interlock fabric:
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 fabric we need yarn count 35.24/s
Select the correct Yarn count for Pique fabric:
Pique
Say, The require GSM is 180
Yarn Count = (-0.146) X (GSM) + 57.16
= (-0.146) X (180) + 57.16
= -26.28 + 57.16
= 30.88
So, to knit 180 gsm Pique Fabric we need yarn count 30.88/s
Select the correct Yarn count for 1X1 Rib fabric:
1X1 Rib
Say, The require GSM is 200
Yarn count = (-0.123) X (GSM) + 54.57
= (-0.123) X (200) + 54.57
= -24.6 + 54.57
= 29.97
So, to knit 200 gsm 1X1 Rib fabric we need yarn count 29.97/s
Select the correct Yarn count for Lycra 1x1 Rib fabric:
Lycra 1x1 Rib
Say, The require GSM is 220
Yarn count= (-0.119) X (GSM) + 59.12
= (-0.119) X (220) + 59.12
= -26.18 + 59.12
= 32.94
So, to knit 220 gsm Lycra 1x1 Rib fabrics we need yarn count 32.94/s
Select the correct Yarn count for Lycra 2x2 Rib fabric:
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 fabric we need yarn count 32.86/s
