Yarn
Count:
Yarn count is very useful to know the condition of yarn. I mean,
yarn is thick or thin. So we can define count in the following way,
The yarn count is a numerical expression which indicates the coarseness or fineness of a yarn.
Fabric GSM:
GSM means Grams per Square Meter. Fabric GSM means weight of one square meter fabric in grams.GSM plays an important role in textile industry. It is
widely used in case of knit fabric measurement. By this we can compare the
fabrics in unit area which is heavier and which is lighter.

How do Select
the Correct Yarn Count for Your Specific Fabric GSM?
How to select yarn count for specific fabric GSM is
a very common and technical task for textile engineers. By the using following
formula you can easily select the actual yarn count for knit the fabric. These
are varying 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
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
Lycra Single Jersey:
Say, the require GSM is 160
Yarn count = (-0.141) X (GSM) + 50.22 + Denier %
= (-0.141) X (160) + 50.22 + Denier %
= -22.58 + 50.22 + Denier %
= 27.66 + Denier %
Hear,
Denier
140 = 20% এবং Denier 70 = 40%
So, to knit 160 gsm single jersey fabric we need yarn count 27.66/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
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
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 25 /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
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
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
Lycra 1×1 Rib:
Let, required fabric GSM is 180
Yarn Count = (-0.119) GSM + 59.12
= (-0.119) x 180 + 59.12
= -21.42 + 59.12
=37.7
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
Lycra 1×1 Rib:
Let, required fabric GSM is 180
Yarn Count = (-0.119) GSM + 59.12
= (-0.119) x 180 + 59.12
= -21.42 + 59.12
=37.7
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
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
