Polyester cotton abnormal fiber types

During the production of polyester cotton, it is inevitable to cause some abnormal fibers due to the conditions of the front spinning or the back spinning. Especially the recycled cotton produced from recycled chips is more likely to produce abnormal fibers; the abnormal fiber outsole can be divided into the following types:


(1) Single thick: fiber with incomplete extension. This kind of fiber is easy to cause abnormal dyeing and has less impact on non-woven fabrics that do not need to be dyed, but for water card cloth or needles used for artificial leather base fabrics. The thorn cloth has a serious impact.


(2) Parallel silk: Two or more fibers stick together after stretching. This kind of fiber is easy to cause abnormal dyeing and has less impact on non-woven fabrics that do not need to be dyed, but for artificial leather base fabrics The water card cloth or needle-punched cloth has a serious impact.


(3) Glue: Broken or twisted filaments occur during stretching, so that the fibers are not stretched to form hard cotton. This kind of product can be divided into first-grade gel, second-grade gel, and third-grade gel. After the carding process, such abnormal fibers are often deposited on the card clothing, causing problems such as poor web formation or broken webs. This raw material will cause serious quality defects to most non-woven fabric products.


(4) Oil-free cotton: During the extension period, there is no oil on the fiber due to the unsatisfactory driving conditions. This kind of fiber usually has a dry feel. In addition to causing static electricity in the non-woven production process, it also causes semi-finished products to be behind. Organize the problem.


(5) For the above four kinds of abnormal fibers, single thick and double filaments are more difficult to remove during the production of non-woven fabrics. Gelatinous and oil-free cotton can be removed as long as the production staff pay a little attention to reduce product quality. defect.
