Introduction
Blending
and mixing is a very important part of the spinning process. Different grade
fiber is used in the spinning process for cost reduction, making good quality
yarn, etc.
Blending
In
the spinning process, when various fibers of different or the same grades are kept
together then it is called blending. For example, a yarn produced by using 65%
cotton yarn and 35% polyester yarn then it’s called blending. The mixture is
based on the movement of important fiber properties such as length, fineness,
strength, etc., and proportions and blends the properties under quantitatively
controlled conditions. In the blending process must be a particular ratio of fibers
to mix with each other.

Mixing
In
the spinning process, when various grades of the same fibers are kept together
for manufacturing yarn then it is called mixing. For example, yarn is produced
by using 40% Indian cotton and 60% Egyptian cotton then it is called mixing.
There is no particular ratio of fibers to mix with each other. Raw cotton is
the main material that affects the quality of yarn. The main technical
challenge of any textile process is to convert the high variability in the
properties of the input fibers to uniform ends. This critical work is largely
achieved in the mixing process. The mixing department in the spinning mill
plays a crucial role in the formulation of an appropriate mix of fibers.

The objective of blending and mixing-
1. The main objective of blending/mixing is
cost reduction.
2. To get a good quality product.
3. To get varieties of yarn.
4. To get the proper strength of the yarn.
5. To get good fineness of the yarn.
Conclusion
Blending/mixing
has a significant impact on end-product cost and quality. One mill can control
the total cost of cotton by purchasing the right quality cotton at the right
time as the price of cotton fluctuates significantly over the years and by the
efficient formulation of mixings for the various counts of yarn that are being
spun.
