Sewing Thread Consumption Per Inch

Sewing Thread Consumption Per Inch:

Sewing Thread Calculation: Total Sewing inch × Average sewing thread per inch (22.5”) = Total sewing thread (inch) Total sewing thread (inch) ÷ 39.37 = Sewing Thread (Total Metter) {Sewing Thread (Total Metter) + 15% Sewing wastage} ÷ 3800 = Total cones.  Approx sewing thread consumption of different items

Relation between Stitch Lengths, Yarn Count, GSM & Machine Dia

Stitch length:

Stitch length (knitting) is the length of yarn in a knitted loop. Stitch length is theoretically a single length of yarn which includes one needle loop half the length of yarn (half of a sinker loop) between that needle loop and the adjacent needle loops on either side of it.

Yarn count:
Yarn count is the numerical expression which indicates or expressed the fineness or coarseness of yarn. According to Textile Institute, Count a number indicating the mass per unit length or the length per unit mass of yarn. 

GSM:

‘GSM’ means ‘Gram per square meter’ that is the weight of fabric in gram per one square meter. By this we can compare the fabrics in unit area which is heavier and which is lighter. The GSM of fabric is one kind of specification of fabric which is very important for a textile engineer for understanding and production of fabric. 

1. Relation between Yarn count & GSM. 

For Single jersey, Count=4350/GSM and 

Ne=50.22-0.141GSM (For single Jersey) 

Ne=54.57-0.123GSM (For 1x1 Rib) 

Ne=59.12-0.119 GSM (For Lycra 1x1 Rib)

2. Relation between GSM, Stitch Length and Yarn Count. 

                                 K 
GSM = …………………………………….                    k=constant 
             Yarn count (Ne) X Stitch length 

K=12068.59 (Single jersey or plain) 

K=16431.497 (1x1 Rib) 

K=19005.333 (2x1 Rib) 

3. Relation between Fabric Dia & machine Diameter. 
Fabric Dia = (Machine Dia X 2) ± 5% for single jersey 
Fabric Dia = (Machine Dia X 4/3) ±5% For Rib.

Relation between Finished GSM and Yarn Count of Various Fabrics

Introduction:

‘GSM’ means ‘Gram per square meter’ that is the weight of fabric in gram per one square meter. It is one kind of specification of fabric. Count is the coarseness or fineness of yarn. There are important relation between yarn count and GSM in knitted fabric. In this article there are some relation are given for different fabrics.

Table-1: Relation between finished G.S.M. and yarn count of s/j and rib fabric
