Problems solved by technology

Plasma wool fabric anti-felting finishing is a research hotspot today, but the technology is not very mature, and the equipment used is expensive
[0004] Chinese patent CN201210391700.9 discloses a method of applying ultrasonic technology to the anti-felting treatment of protease wool, which uses ultrasonic waves to increase the hydrolysis rate of protease, accelerate the shedding of wool scales, and shorten the time of enzymatic anti-felting treatment. Reduce the degradation of the inside of the fiber by protease. However, the molecular weight of the protease that can be used for wool anti-felting finishing is relatively small, and it is easy to diffuse into the main body of the fiber through the cell membrane complex layer in the scale gap, hydrolyze the intercellular substance, and seriously damage the fiber strength. damage
Chinese patent CN201210391700.9 discloses a modified protease anti-felting composition, which is used for anti-felting finishing of wool fibers, but the process is relatively complicated and not suitable for industrial production

Embodiment 1

[0022] An anti-felting finishing method for wool fabrics, comprising the following steps:

[0023] (1) Weigh 10 g of protease and 80 g of deionized water, mix and stir evenly, add 4 g of polyurethane sulfonate and 2 g of silane coupling agent, heat up to 60 ° C, and ultrasonicate for 30 min at a power of 500 W to obtain a mixed dispersion;

[0024] (2) Add 1 g of nano-titanium oxide powder to the mixed dispersion liquid obtained in step (1), and ultrasonicate for 20 min at a power of 500 W to obtain an anti-felting finishing liquid;

[0025] (3) Immerse the woolen fabric in the anti-felting finishing solution obtained in step (2), the bath ratio is 1:80, ultrasonically for 10 minutes at a power of 800W, take it out, wash it with flowing water 2-3 times, and heat it at 60°C Down drying to obtain wool fabrics with anti-felting finish.

Embodiment 2

[0027] (1) Weigh 10 g of protease and 80 g of deionized water, mix and stir evenly, add 4 g of polyurethane sulfonate and 2 g of silane coupling agent, heat up to 70 ° C, and ultrasonicate for 80 min at a power of 500 W to obtain a mixed dispersion;

[0028] (2) Add 1 g of nano-titanium oxide powder to the mixed dispersion liquid obtained in step (1), and ultrasonicate for 20 min at a power of 500 W to obtain an anti-felting finishing liquid;

[0029] (3) Immerse the woolen fabric in the anti-felting finishing solution obtained in step (2), the bath ratio is 1:80, ultrasonically for 30 minutes at a power of 800W, take it out, wash it with running water 2-3 times, and heat it at 80°C Down drying to obtain wool fabrics with anti-felting finish.

Embodiment 3

[0031] (1) Weigh 10 g of protease and 80 g of deionized water, mix and stir evenly, add 4 g of polyurethane sulfonate, 2 g of silane coupling agent, heat up to 62 ° C, and ultrasonicate for 40 min at a power of 500 W to obtain a mixed dispersion;

[0032] (2) Add 1 g of nano-titanium oxide powder to the mixed dispersion liquid obtained in step (1), and ultrasonicate for 20 min at a power of 500 W to obtain an anti-felting finishing liquid;

Abstract

The invention discloses a felt proofing method for wool fabrics. The felt proofing method comprises the following steps: preparing felt proofing liquid; soaking the wool fabrics in the felt proofing liquid for finishing; cleaning and drying the finished wool fabrics to obtain felt proofing wool fabrics. The felt proofing method for wool fabrics, provided by the invention, can be used for effectively improving the felt proofing property of the wool fabrics without generating damage to the strength of the wool fabrics, the finishing method is simple and easy to operate, and no toxic substance is released in the finishing process, thereby being conducive to environmental protection.

Description

Technical field: [0001] The invention relates to a fabric finishing technology, in particular to a wool fabric anti-felting finishing method. Background technique: [0002] Wool fiber aggregates or woolen fabrics are repeatedly squeezed and rubbed in soaping solution, acidic solution or other similar aqueous solutions, the fibers are entangled and felt together, the gaps between the fibers become smaller, and gradually become tighter, and cannot be restored to the original state of dispersion. One characteristic is called felt shrinkage. Felting will affect the wearing performance of woolen fabrics, so it is of great significance to perform anti-felting finishing on woolen fabrics. [0003] There are currently two methods, namely "subtractive" anti-felting treatment and "additive" anti-felting treatment. "Subtraction" anti-felting treatment uses oxidants or enzymes to treat the wool to destroy the scale layer of wool to achieve the purpose of anti-felting. The oxidizing a...
