Different Qualities of Yarn that are Used for Knitting Process

Yarns Required for Knitting: 

The main raw material for Knitting process is Yarn. So its quality should be standardized. The quality of yarn should be like as follows :

Table: Following are the different qualities of Yarn that are used for Knitting process:

Type	Texture	Count
A	Cotton	40/1 Ne
		34/1 Ne
		30/1 Ne
		26/1 Ne
		20/1 Ne
B	T.C.	34/1 Ne
		30/1 Ne
		28/1 Ne
		26/1 Ne
		20/1 Ne
C	CVC	34/1 Ne
		30/1 Ne
		26/1 Ne
D	Mellange	30/1 Ne
		26/1 Ne
		22/1 Ne
		20/1 Ne
E	Spandex	40 Denier
		70 Denier
F	Polyester	75 Denier
		150 Denier
G	Sewing Thread	40/3 Ne
		150 Denier

Minimum requirement of other parameters are :

For Yarn : 

1. Yarn strength 13 gm/Tex (minimum)
2. Should be waxed 0.1% - 0.3% (on the weight of the material)
3. Yarn should not be dry
4. Cone angle should be accurate
5. A tail should be kept during winding
6. Packing density must be maintained

For Spandex 

1. Should have good elasticity
2. Yarn should be uniform
3. Elastic recovery 100%
4. Elongation 500%.
5. Should be Acid, Alkali and temperature stable 

Knitting Machine Set-up In accordance with Yarn:

Table: Operator sets the following parameters prior to operation

Parameters	Range
Speed	26 ~ 28 RPM (for Solid dyed)
	20 ~ 25 RPM (for Yarn dyed & designed)
Yarn Tension	4 ~ 5 gm/tex.
Stitch Length	2.60 ~3.00 mm
Weight	100 ~ 240 GSM (as requested)
Yarn (Cotton)	16 ~ 40 Ne
Yarn (Polyester)	75 ~ 300 Denier
