Preparation method of one-way seepage fabric with dry inside and wet outside

Abstract

The invention relates to a preparation method of a one-way seepage fabric with a dry inside and a wet outside, one side of the fabric has the hydrophilic property, and the other side has the hydrophobic property. The preparation method comprises the following steps of: a, adding a hydrophilic aid in a staining solution while dying the fabric; b, drying; c, immersing a surface active agent on the fabric while molding; d, drying; e, distributing a hydrophobic aid and auxiliary aids, such as adhesives, acetic acid and the like, on the surface layer on one side of the fabric by using a coating technology; and f, drying. Before coating processing, the fabric is decationized so that anions and cations are balanced, or the number of the cations can almost be ignored. The fabric is a pure cotton fabric or has a cotton content of more than 50%. In the preparation method, the temperature for drying is between 80 DEG C and 170 DEG C. The one-way seepage fabric with the dry inside and the wet outside has the functions of one-way seepage and waterproofness, one side of the fabric is dry, and the other side is hydrophilic, which can diffuse water rapidly.

Description

technical field [0001] The invention relates to a method for preparing a fiber fabric, in particular to a method for preparing a fiber fabric that has a hydrophilic property on one side and a hydrophobic drainage property on the other side, and is dry on the inside and wet on the outside. Background technique [0002] In the textile field, the ideal fabric with sweat-absorbing, sweat-wicking, rain-proof and dry inside has always been pursued by people. The fabric is characterized by being wet on the outside and dry on the next-to-body side. When the human body sweats, the fabric can automatically absorb and drain sweat to the clothes. The outer layer spreads out. After the sweat is diffused, the sweat is more likely to volatilize. It needs to absorb heat during the volatilization process, so the heat on the surface of the human skin is taken away, and the person feels cool. When it rains lightly, the raindrops fall on the outer layer of the clothes, but It cannot penetrate i...

Problems solved by technology

However, the conflict between water absorption and waterproofing, water back-penetration and the washability of fabrics have not been solved technically.
