Embodiment 1

[0025] A kind of production method of the wool fabric of low shrinkage rate, concrete production method is as follows:

[0026] 1) Put the woolen fabric in a container, let in air with a temperature of 40°C and a relative humidity of 50% for humidification and preheating, and wait for the temperature and moisture content of the woolen fabric to be stable within 30 minutes, then add octadecyl Trimethylammonium chloride aqueous solution is atomized, mixed with air at a temperature of 60°C and a relative humidity of 70%, and then passed into the container to perform secondary humidification and preheating on the wool fabric. It can be stable within 30 minutes;

[0027] 2) Put the wool fabric that has been humidified and preheated into an airtight container, and use an ozone generator to pass ozone into the airtight container. After 1 hour of treatment, pressurize to 2MPa, keep the pressure for 30 minutes, and slowly release the pressure to normal pressure. Stand still at -5°C fo...

Embodiment 2

[0040] A kind of production method of the wool fabric of low shrinkage rate, concrete production method is as follows:

[0041] 1) Put the woolen fabric in the container, let in air with a temperature of 45°C and a relative humidity of 55% for humidification and preheating, and wait for the temperature and moisture content of the woolen fabric to be stable within 30 minutes, then add octadecyl The trimethylammonium chloride aqueous solution is atomized, mixed with air at a temperature of 65°C and a relative humidity of 75%, and then passed into the container to perform secondary humidification and preheating on the wool fabric. It can be stable within 30 minutes;

[0042] 2) Put the wool fabric that has been humidified and preheated into an airtight container, and use an ozone generator to inject ozone into the airtight container. After 1.5 hours of treatment, pressurize to 3MPa, keep the pressure for 40 minutes, and slowly release the pressure to normal pressure. Stand still...

Abstract

The invention discloses a production method for a low-shrinkage-rate wool fabric. The production method comprises the specific steps that 1, a wool fabric is humidified and pre-heated, and then an octadecyl trimethyl ammonium chloride water solution is atomized to be mixed with air to conduct secondary humidifying and pre-heating on the wool fabric; 2, the wool fabric obtained after humidifying and pre-heating is subjected to ozone treatment, after pressure increasing and maintaining treatment, freezing is conducted, a graphene-grafted polymer water solution is atomized and then mixed with nitrogen, the mixture of the graphene-grafted polymer and the nitrogen is pre-heated, injected into a container and subjected to ultrasonic oscillation; 3, the wool fabric is taken out and subjected to fixation by using a high-temperature and low-temperature combined method; 4, the wool fabric is pre-dried, baked and then subjected to water washing and drying, and if the wool fabric is qualified through quality testing, the wool fabric is packaged to obtain the low-shrinkage-rate wool fabric. According to the method, the wool fabric is treated, the shrinkage rate of the wool fabric can be remarkably reduced, the shrinkage resistance of the wool fabric can be improved, the dimensional stability of the wool fabric is improved, and therefore, the application requirements of the wear field are met.

Description

technical field [0001] The invention belongs to the technical field of clothing fabrics, and in particular relates to a method for producing low-shrinkage wool fabrics. Background technique [0002] Cashmere fiber is a natural and precious textile material. In recent years, cashmere clothing products have become more and more popular and valued by consumers due to their comfortable feel, unique color, light texture, good warmth and breathability in the fierce clothing market competition. . However, because the wool fabric is composed of scales and cortex, the scales have a certain height and thickness, and some edges are zigzag, shaped like barbs, and it is easy to cause fibers to collude and stick together during the wearing process. The middle fibers rub against each other, and the jagged scales mesh with each other, resulting in shrinkage. After shrinking, the size of wool clothing will change greatly, and it may even be impossible to wear. [0003] In order to suppres...
