Problems solved by technology

At present, the widely used chlorination anti-shrinkage method will produce a large amount of harmful substances and endanger the environment. Therefore, it is necessary to study an environmentally friendly anti-shrinkage method, which can not only reduce the felt shrinkage of the fabric, but also maintain the good wearability of the fabric.

Embodiment 1

[0021] A method for manufacturing washed wool with strong felting resistance, comprising the following steps:

[0022] 1) Ultraviolet light treatment: spread the wool fiber evenly on the bottom of the ultraviolet light irradiation device. The distance between the wool fiber and the ultraviolet lamp is 12cm, and the irradiation time is 25min. , after the irradiation is completed, take out the wool fiber, wash it with clean water for 15 minutes, and then dry it at 75°C;

[0023] 2) Ozone oxidation treatment: soak the wool fiber treated in step 1) with water to make it fully wet, and then send the wet wool fiber into a closed space full of ozone for ozone oxidation treatment. After the ozone oxidation treatment is completed, Take out the wool fiber, wash it with clean water for 15 minutes, and then dry it. The soaking time of the wool fiber is 3 minutes, the ozone oxidation time is 1.1 minute, the ozone concentration is 2% (o.w.f), and the drying temperature is 75°C;

[0024] 3)...

Embodiment 2

[0027] A method for manufacturing washed wool with strong felting resistance, comprising the following steps:

[0028] 1) Ultraviolet light treatment: Spread the wool fiber evenly on the bottom of the ultraviolet light irradiation device. The distance between the wool fiber and the ultraviolet lamp is 14cm, and the irradiation time is 30min. After the irradiation is completed, take out the wool fiber, wash it with clean water for 12 minutes, and then dry it at 80°C;

[0029] 2) Ozone oxidation treatment: soak the wool fiber treated in step 1) with water to make it fully wet, and then send the wet wool fiber into a closed space full of ozone for ozone oxidation treatment. After the ozone oxidation treatment is completed, Take out the wool fiber, wash it with clean water for 12 minutes, and then dry it. The soaking time of the wool fiber is 5 minutes, the ozone oxidation time is 1.5 minutes, the ozone concentration is 3% (o.w.f), and the drying temperature is 80°C;

Abstract

The invention provides a scoured wool with high felting shrinkage resistance and a manufacturing method of the scoured wool, and relates to the field of wool manufacturing. By sequentially conductingultraviolet light treatment, ozone oxidation treatment, ultrasonic treatment and chitosan treatment on the wool, the wool has the good felting shrinkage resistance, wherein specific operation of ultraviolet light treatment is as follows: wool fibers are evenly spread at the bottom of an ultraviolet light irradiation device flatly, the distances between the wool fibers and a ultraviolet lamp tube are 12-14 cm, the irradiation time is 20-30 min, after the time is up, the wool fibers are turned over and then irradiated for 20-30 min, and after irradiation is completed, the wool fibers are taken out, scoured with clear water for 10-15 min and then dried.

Description

technical field [0001] The invention relates to the technical field of wool production, in particular to a washed wool with strong anti-felting property and a production method thereof. Background technique [0002] Wool is mainly composed of protein. Wool fibers are soft and elastic, and can be used to make textiles such as woolen wool, woolen yarn, blankets, and felt. Wool products have the characteristics of plump hand feeling, good warmth retention and comfortable wearing. The main factors for evaluating the quality of wool are fineness, crimp, color, strength and weed content. [0003] Wool (wool) is an important raw material in the textile industry. It has the advantages of good elasticity, strong hygroscopicity, and good warmth retention. However, due to the high price, it is not used much for the production of nonwovens. Non-woven fabrics produced from high-quality wool are limited to some high-grade industrial fabrics such as needle-punched blankets and high-gra...
