Different Methods Of Blending Polyester Yarn With Cotton

1. Purpose of cotton matching:
A. In order to maintain the stability of production and yarn quality
The production process and yarn quality must be kept relatively stable to produce at the highest cost. Keeping the properties of raw cotton relatively stable is an important condition for stable production and quality. If a single shipping mark is used for spinning, when one batch of raw cotton is used up, another batch of raw cotton must be replaced by a weighed-batch. Such frequent and large exchange of raw materials is bound to cause fluctuations in production and yarn quality. If a variety of raw materials are used together, as long as they are properly matched, the properties of mixed cotton can be kept relatively stable, so that the production process and the quality of yarn can also be kept relatively stable.
The rational use of raw cotton, as far as possible to meet the quality of yarn and yarn count requirements, because the quality and characteristics of yarn requirements are not the same, coupled with the spinning process has its own characteristics, so all kinds of yarn to use raw cotton quality requirements are not the same. In addition, the quantity of raw cotton stored in cotton mills is more or less, and the quality is high or low. If a kind of raw cotton or a batch number of raw cotton is used to make a kind of yarn, it is difficult to meet the requirements in quantity and quality. Therefore, mixed cotton yarn should be used to make full use of the characteristics of various raw cotton, learn from each other and meet the requirements of yarn quality.
B. In order to save cotton and reduce costs
Raw cotton is according to the quality of the price, different fiber length, different grades of raw cotton price difference is very big, raw cotton investment in cotton yarn cost accounts for 50%- 85%(depending on the variety), if the selection of high grade of raw cotton, although yarn quality can be perfect, but the increase of production cost, means that the profit of tons of yarn, therefore, cotton should start from the economic benefit, Control the unit price of cotton matching and the amount of cotton used per ton of yarn to save the cost of raw cotton, such as: In the mixed cotton with short fiber length, proper mixing of a certain proportion of long and low grade raw cotton will not reduce the quality of yarn, but improve the strength of yarn. For raw cotton underfoot, flower-back, combed cotton, reused cotton and other components, it can be reused in a certain proportion, which can also reduce the cost of cotton and save the effect of cotton.
