Polyester fiber capable of absorbing moisture and releasing sweat

Abstract

The invention relates to the technical field of fiber materials and particularly relates to a polyester fiber capable of absorbing moisture and releasing sweat. The fiber comprises a core layer and a skin layer, wherein the core layer is made from a hydrophilic polymer, the skin layer is made from dacron, the cross section of the fiber is Chinese-character-'mi'-shaped, and seven independent cavities are formed inside the fiber; and the skin layer is further coated with a coating layer, and a plurality of micropores are formed in the surface of the fiber. According to the polyester fiber, the hydrophilic polymer is designed inside the dacron, so that the polyester fiber disclosed by the invention plays roles in absorbing and guiding the moisture, and thus the effect of absorbing the moisture and releasing the sweat is achieved; due to the Chinese-character-'mi'-shaped structure design, the specific surface area of the polyester fiber is greatly increased, and the moisture absorbing and sweat releasing effect is greatly improved; and the micropores are formed in the surface of the fiber, due to the micropore design, the air permeability of the polyester fiber is improved, and meanwhile, the moisture absorbing and sweat releasing performance of the polyester fiber is improved.

Description

technical field [0001] The invention relates to the technical field of fiber materials, in particular to a moisture-absorbing and sweat-wicking polyester fiber. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for the quality of underwear are getting higher and higher, so the comfort, health, safety and environmental protection of clothing fabrics are the focus of people's consideration. Along with the increase of people's outdoor activities, people are prone to sweating. However, natural fibers take cotton as an example, which has good hygroscopicity, but when people sweat a little, the cotton fibers will swell due to moisture absorption, causing discomfort when pasted on the skin. This creates a feeling of coldness and dampness to the human body; synthetic fibers such as polyester have low water absorption and poor moisture permeability, and are prone to stuffy feeling after sweating. Therefore, traditional...

Problems solved by technology

However, natural fibers take cotton as an example, which has good hygroscopicity, but when people sweat a little, the cotton fibers will swell due to moisture absorption, causing discomfort when pasted on the skin. As a result, it creates a cold and wet feeling to the human body; while synthetic fibers such as polyester have low water absorption and poor moisture permeability, and are prone to stuffy feeling after sweating.

Therefore, traditional fabrics have poor moisture absorption and perspiration effects.
