Abstract

The invention provides a high-breathability polyester staple fiber. The high-breathability polyester staple fiber comprises a staple fiber body which is provided with porous channels extending in the length direction, the outer contour of the cross section of the staple fiber body is a regular octagon, the cross section of each porous channel is in the shape of a triangular star, and the outer wall of the staple fiber body is provided with a plurality of wavy grooves wandering in the length direction. The high-breathability polyester staple fiber has high compression rebound resilience, a certain air circulation rate exists in the fiber, the warm keeping, moisture absorbing and ventilation performance is good, and fabric made from the high-breathability polyester staple fiber is excellent in air feel and softness; besides, the firmness degree is high, the service life is long, and adaptability is high.

Description

technical field [0001] The invention relates to the technical field of textile materials, in particular to a strong air-permeable polyester staple fiber. Background technique [0002] Polyester staple fiber is a fiber obtained by spinning polyester into tow and cutting it. Polyester is polyethylene terephthalate, or PET for short, which is polymerized from PTA and MEG. Currently, it is woven from polyester staple fiber Although the fabric has excellent properties such as strength, heat resistance, chlorine resistance, light resistance, chemical resistance and shapeability, it is very dense and impermeable, and its moisture absorption and perspiration function is very low, so it is not suitable for summer clothing. fabric raw materials. How to make polyester fabrics have good moisture absorption and perspiration performance is the goal pursued by many chemical fiber developers. With the improvement of people's living standards, clothing fabrics will put forward higher requir...
