Blending Process In Spinning Department

Blending 

Object :-

• To provide the required feature to the end product.
• To control and decrease of yarn production cost.
• To achieve uniform quality of yarn.
• To develop yarn processing performance.
• To achieve different effect by carrying color,characteristics of fibre.                       

Definition :-  Blending is process of combining two or more type of fibre. Fibre in required                           ratio are taken, opened and blended in blenders. During blending anti-static  agent are spray on given the fibre. The mixing is blended once or twice to ensure proper blending to the fibre. Blending is done to get desired properties in the finished products. It improves the fabric performance and helps in maintaining the economy of the product.

Exp:- P/V 65/35,P/C 70/30,etc.

Practically blending process involves reopening, mixing, toppling and conditioning of the fibre along with addition of predetermined quantities of usable waste.

Antistatic Finish: During blending the fibre is given antistatic finish to prevent static charge generation as well as fly generation in the case of Man-Made fibre.

Chemical used:

• ·         LV40 – prevents static charge generation.
• ·         2152P – prevents fly generation.
