Abstract

The invention provides a kind of super imitation cotton polyester filament, comprising polyester FDY yarn and superfine polyester POY yarn, polyester FDY yarn and superfine polyester POY yarn are composited together through false twist deformation processing, and the polyester FDY yarn has a fineness of 0.5-1.5D, semi-dull polyester FDY yarn with elongation at break of 25%-35%, the semi-dull polyester FDY yarn is a tow composed of several monofilaments, and the cross-sectional shape of the monofilament is cross-shaped; Superfine polyester POY yarn is full-dull superfine polyester POY yarn, the fineness of the full-dull superfine polyester POY yarn is 0.5-1.5D, and the elongation at break is 100%-135%. It is a tow composed of several monofilaments, and the cross-sectional shape of the monofilaments is circular. The beneficial effect of the present invention is that its softness, water absorption, moisture permeability and quick-drying property are all superior to those of pure cotton fiber, which can achieve the purpose of replacing cotton fiber, greatly reducing the dependence of the textile industry on natural cotton, and alleviating The problem of shortage of cotton resources.

Description

technical field [0001] The invention relates to the field of chemical fibers, in particular to a super cotton-like polyester filament. Background technique [0002] Cotton fiber is a natural raw material in traditional spinning. It has strong hygroscopicity and air permeability. It is an excellent natural fiber. It does not have any irritation when it comes into contact with human skin and is relatively comfortable. However, due to the decreasing area of ​​arable land, the land for planting cotton is also constantly decreasing. At the same time, due to the constraints of seasonal and regional conditions of cotton growth and the continuous increase of the global population, cotton is far from being able to satisfy people's clothing and various needs. The consumption demand for cotton products caused the price of cotton to skyrocket. Therefore, in order to solve the problem of shortage of cotton resources, it has become another technical problem to be solved by those skilled ...
