The quality of yarn depends largely on mixing and blending process. Mixing and blending process for yarn is the first technical step of a yarn manufacturer. Cotton guides of different grades are selected separately for the preparation of yarn of different counts.
All the production officer or production manager also needs to have a good idea about mixing/blending process for yarn.
Mixing and blending process for yarn. It is also important to have a good idea about the bell fibers used. Otherwise, it is normal to make mistakes in mixing and blending. If there is a mistake in mixing, the quality of the yarn produced will be as bad on the one hand and the production cost will also increase on the other hand. Cotton dye also plays an important role in mixing/blending But there is a slight color difference in the cotton of the same position, but there is no problem with the yarn made by this cotton. Usually different colored yarns are not acceptable for the same mixing. In different countries or even in the same country or in the same region, there are different types of fibers due to soil fertility, rainfall, soil type, sowing period, cotton production period, loss of insect infestation, etc reasons There are different types of ash. Mixing blending is the process of mixing different quality or different grades of cotton together to produce the desired and quality yarn and reduce the production cost of the yarn produced.
Mixing: A similar mixture of fiber is called mixing.
Blending: Different mixture of fiber is called blending.
Objectives of mixing and blending:
The purposes of mixing and blending are given below
1. To control the price of yarn produced.
2. To make the yarn of the desired energy.
3. Improving procedural work.
4. Making yarn of the desired quality.
5. Uses relatively low quality or discarded fiber with relatively high-quality fiber Prevent wastage.
6. Creating a competitive market by creating opportunities for the use of substandard or discarded fiber.
7. Increase procedural skills.
8. To increase the durability of the yarn produced.
Notable features of mixing and blending:
Mixing and blending should be done with the following points in mind.
1. Equilibrium or similarity of the lengths of the fibers.
2. The fibers of symmetry.
3. The power of fiber.
4. Atmospheric conditions.
5. Fiber color equality.
6. Skilled workforce.
7. Fiber maturity.
8. Good equipment.
9. Equal subtlety
