Problems solved by technology

Because there are only two terminal alcohol hydroxyl groups in its molecule, there are no other polar groups, and the PET macromolecular chain has a very symmetrical structure and a high degree of crystallization, so the hydrophilicity of the PET fabric is extremely poor, that is, the hygroscopicity is relatively poor.

Abstract

The invention relates to the technical field of non-woven fabrics, and discloses a finishing process of moisture-absorbing and sweat-wicking polyester non-woven fabrics. The finishing process of the moisture-absorbing and sweat-wicking polyester non-woven fabrics comprises the following steps that (1) the polyester non-woven fabrics are placed in an ethanol solution for ultrasonic vibration cleaning; (2) a vinyl acetate-maleic anhydride copolymer is added to absolute ethanol, the mixture is heated and stirred to be dissolved to obtain a vinyl acetate-maleic anhydride copolymer solution, a sodium hydroxide ethanol solution is added dropwise to the vinyl acetate-maleic anhydride copolymer solution, the mixture is stirred and subjected to alcoholysis to obtain an alcoholysis solution, modified zeolite is added to the alcoholysis solution, and the mixture is uniformly dispersed by ultrasonic oscillation to obtain a hydrophilic finishing agent; (3) the polyester non-woven fabrics are immersed in the hydrophilic finishing agent, a glutaraldehyde crosslinking agent is added dropwise to carry out the crosslinking reaction, and nascent moisture-absorbing and sweat-wicking polyester non-woven fabrics are obtained; (4) the nascent moisture-absorbing and sweat-wicking polyester non-woven fabrics are arranged in an oven for heat drying treatment to obtain the moisture-absorbing and sweat-wicking polyester non-woven fabrics. The polyester non-woven fabrics have excellent moisture-absorbing and sweat-wicking performance and are comfortable to wear.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a finishing process for moisture-absorbing and sweat-wicking polyester non-woven fabrics. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have the characteristics of breathability, softness, light weight, non-toxic and non-irritating, rich colors, and low prices. For example, polyethylene terephthalate pellets are used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, hot rolling, and coiling. Polyethylene terephthalate, also known as PET, is currently a fiber with large industrial scale, large usage, rapid development and wide application. PET is often selected as a base fabric material because its molecules are linear, the molecules are arr...
