CVC Yarn: 

In a cotton fiber polyester blended yarn, when the total of cotton fiber is to a greater extent than than polyester fibre it is called CVC yarn. Here CVC stands for Chief Value of Cotton i.e., the ratio of cotton fiber fibre is ever inwards a higher house 50% or more.

Example: 30 s/1 Ne (60/40) CVC Yarn means, It is a xxx count unmarried ply cotton-polyester blended yarn where the ratio of cotton fiber fibre to polyester fibre is lx to 40.

PC Yarn: 

A polyester cotton fiber fibre blended yarn is called PC yarn, but inwards full general where the total of polyester fibre is to a greater extent than than cotton fiber fibre is called PC yarn. Here PC stands for Polyester Cotton.

Example: xxx s/1 (60/40) Ne PC Yarn means, It is a xxx count unmarried ply cotton-polyester blended yarn where the ratio of polyester fibre to cotton fiber fibre is lx to 40.

It tin hold out said that every CVC yarn is besides PC yarn but all the PC yarns are non CVC yarn.

The near pop argue for blending is that of combining the properties of 2 or to a greater extent than fibers. Blending of dissimilar fibers is besides used to growth aesthetic effects inwards the fabric.

 
Polyester/cotton blend is an example; a skillful cease role is inwards suiting. Polyester is a man-made fiber amongst high abrasion resistance together with cotton fiber is a natural fiber together with has skillful wet absorbency & feel.

Blending Process of Cotton-Polyester Fibre:

To make a CVC/PC yarn the fibers must hold out blended earlier it reaches to ring frame machine every bit roving. This blending procedure mainly tin hold out done inwards 2 manners.

1. Fibre Blending:

According to the blending ratio of cotton fiber & polyester fibre inwards the yarn, numbers of cotton fiber & polyester bales are given inwards the laydown inwards blowroom using bale management. Then the both fibres piece of employment past times consecutively through the fibre plucker machine- generally used - Uniflock (Rieter) or Blendomat (Trutzschler) machine together with and thus gradually dissimilar cleaning machines. The homogenous blending of fibres takes house at mixing machine- generally used as- Unimix (Rieter) or Multimixer (Trutzschler) machine. This type of mixing/blending is called fibre blending. From this type of blending, blended carte du jour slivers tin hold out obtained. Then the regular spinning menses chart is followed till band frame machine to make PC/CVC blended yarn.

2. Sliver Blending:

In this process, cotton fiber fibres & polyester fibres are processed through split machines from blowroom to carding. Then the split carte du jour slivers are made from polyester & cotton. After that, to ensure improve blending, the polyester carded slivers are passed through 1 stage depict frame which is known every bit pre-pass stage to drib dead along the sliver hank every bit optimum every bit possible. After that according to the required blended ratio the slivers are blended inwards breaker depict frame. In draw frame slivers are doubled, drafted & blended to the required ratio. After that, conventional spinning procedure is followed till ring frame machine to make PC/CVC yarn.

After a lot of experiments, it has been noticed that sliver blending is slightly improve than fibre blending. In sliver blending the ratio of cotton fiber & polyester tin hold out maintained to a greater extent than just than fibre blending.
