Polyester cotton in the production period because of the spinning or spinning conditions, it is inevitable that some abnormal fibers, especially the use of recycled chips produced by the reclaimed cotton, more likely to produce abnormal fibers; abnormal fiber outsole can be divided into the following types;
(1) Single coarse: Incompletely extending fibers, which are likely to cause abnormal dyeing, and have less effect on non-woven fabrics that are not dyed, but are used for water-based or needle-punched fabrics used in artificial leather base fabrics. Seriously affected.
(B) Parallel filaments: Two or more fibers stick together after stretching. This type of fiber is likely to cause abnormal dyeing. It has less effect on non-woven fabrics that need no dyeing, but it is used for water needles used in artificial leather base fabrics. Cloth or acupuncture has a serious effect.
(3) Colloidal: broken filaments or filaments are formed during extension so that the fibers do not extend to form hard cotton. This product can be further divided into a primary gel, a secondary colloid, and a tertiary colloid. After such an abnormal fiber is subjected to carding, it is often deposited on the clothing cloth to cause problems such as poor formation of the web or broken nets. Such raw materials will cause serious quality defects to most of the non-woven fabric products.
(D) Oil-free cotton: During the extension period, because the car is not smooth, there is no oil on the fiber during the driving. This type of fiber usually has a dry touch, which causes static electricity in the non-woven production process, and also causes the semi-finished products to be processed. problem. woven technologies
(e) The above four kinds of abnormal fibers, single coarse and parallel filaments are more difficult to be removed during the production of non-woven fabrics. Gel-like and non-oily cotton can be removed as long as the production personnel pays a little attention and the defects of product quality are reduced.
