Embodiment 1

[0044] A 100% polypropylene knitted fabric with a density of 160 grams per square meter is passed through a corona discharge machine with a total power of 8000 watts at a speed of 0.5 meters per minute to activate the fiber surface. The activated knitted fabric undergoes surface modification for moisture absorption and perspiration by immersion-pressure absorption-baking. The composition of the pressure-absorbent aqueous solution used is: chitosan (molecular weight 340,000g / mol) 1.25%, acrylic acid 5%, polyvinyl alcohol (molecular weight 22,000g / mol) 8.5%, all based on the weight of the overall solution 100% counted. After the chitosan and polyvinyl alcohol in the composition of the pressure-absorbing liquid are completely dissolved, the pressure-absorbing liquid is heated to 50°C, and 0.3% cerium ammonium nitrate (based on the weight of the whole solution as 100%) is added, and the above is soaked The surface of the activated fiber fabric has a baking temperature of 95°C and a re...

Embodiment 2

[0046] The cloth type and pretreatment conditions are the same as in Example 1. The surface modification is carried out by immersion-pressure suction-baking. The composition of the pressure-absorbing water solution is: chitosan (molecular weight 340,000g / mol) 1.25%, acrylic acid 5%, polyvinyl alcohol (molecular weight 22,000g / mol) 8.5%, all based on 100% of the total solution weight. After the chitosan and polyvinyl alcohol in the composition of the pressure-absorbing liquid are completely dissolved, the pressure-absorbing liquid is heated to 50°C, and 0.5% of cerium ammonium nitrate (based on the total weight of the solution as 100%) is added, and the above is soaked The surface of the activated fiber fabric has a baking temperature of 95°C and a reaction time of 120 seconds. The obtained product is the moisture-absorbing and sweat-wicking fabric of the present invention, and the water evaporation rate is shown in Table 1.

Embodiment 3

[0048] The cloth type and pretreatment conditions are the same as in Example 1. The surface modification is carried out by immersion-pressure suction-baking. The composition of the pressure-absorbing water solution is: chitosan (molecular weight 340,000g / mol) 1.25%, acrylic acid 5%, polyvinyl alcohol (molecular weight 22,000g / mol) 8.5%, all based on 100% of the total solution weight. After the chitosan and polyvinyl alcohol in the composition of the pressure-absorbing liquid are completely dissolved, the pressure-absorbing liquid is heated to 50°C, and 0.5% of cerium ammonium nitrate (based on the total weight of the solution as 100%) is added, and the above is soaked Surface activated fiber fabric. The baking temperature is 95°C, and the reaction time is 120 seconds. The obtained product is the moisture-absorbing and sweat-wicking fabric of the present invention, and the water evaporation rate is shown in Table 1.

Abstract

The invention relates to a method for making fabric having moisture absorbing and sweating property, which includes: pre-activating on the surface of the hydrophobic fabric; then taking grafting reactions with polyalcohol, natural polysaccharide and copolymer formed by unsaturated carboxylic acid with double bond and a covalent bond is formed.

Description

Technical field [0001] The invention relates to a method for manufacturing a fabric with moisture absorption and sweat wicking properties, specifically, a graft reaction is carried out on the surface of a fiber fabric to impart moisture wicking properties to the fabric. Background technique [0002] In the fabric field, "moisture wicking" refers to making non-hydrophilic fabrics have both water absorption and quick-drying properties. Generally speaking, it is difficult for natural fibers or man-made synthetic fibers to have these two properties at the same time. For example, polypropylene fibers in man-made synthetic fibers have the functions of light weight, quick drying, soft touch, heat preservation, antibacterial properties, and high abrasion resistance, and have the potential as high-end clothing materials. However, polypropylene fiber is not hydrophilic, so the sweat permeability is not good, especially in high temperature and high humidity areas or summer is not suitable a...
