Reinforced breathable polyester staple fiber

Abstract

The invention relates to a reinforced breathable polyester staple fiber which comprises a core layer and a skin layer. The core layer and the skin layer are arranged inside and outside. A cavity which is used for air circulation is arranged between the core layer and the skin layer. A number of connection parts are arranged in the cavity, and used for connecting the core layer and the skin layer and dividing the cavity into a number of air flow passages. The cross section of the skin layer is shaped like 8 sleeved by a ring structure. According to the reinforced breathable polyester staple fiber provided by the invention, the fiber has high compressive rebound performance through the cavity between the core layer and the skin layer; the fiber has certain air circulation, and has the great performances of warm keeping, moisture absorption and ventilation; in addition, the cross section of the skin layer is shaped like 8 sleeved by a ring structure, so that the fiber can produce much compact permanent self-crimp twist; and the bulky characteristic index of the fiber and the rigidity and pressure resistance of the fiber are improved.

Description

technical field [0001] The invention relates to the field of textile materials, in particular to a reinforced breathable 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, referred to as PET, 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 setting properties, it is very dense and airtight, and is not suitable for use as a fabric raw material for clothing. [0003] How to make polyester fabrics have good breathability and elasticity is the goal pursued by many chemical fiber developers. With the improvement of people's living standards, clothing fabrics will put forward higher requirements for comfort, and the breathable and heat-preserving function is one of th...
