Problems solved by technology

[0005] 1. The antibacterial effect is not strong, particularly lack of persistence :
[0006] 2. High temperature finishing process Greater damage to woolen fabrics
Since rabbit hair is a natural protein fiber fabric, it may cause protein denaturation and degradation after long-term high-temperature baking, which will reduce the wearable performance of the fabric.
And if the baking time is insufficient, then the crosslink bond that chitosan and rabbit hair forms is too little, makes the antibacterial property of rabbit hair fabric on the low side, especially lacks antibacterial long-acting (washability)

Embodiment 1

[0040] The first way: put 2g of rabbit hair fabric into 10mL of 3% chitosan solution (bath ratio 1:5), shake at a low speed in a constant temperature water bath at 30°C. Soak the head for 30 minutes and remove it, and the excess rate of head rolling is 50%. Second dipping for 30 minutes to remove, second rolling rate of 100%.

[0041] Second step: Put the first finishing fabric into 10 mL of 5% glutaraldehyde solution (bath ratio 1:5), shake at a low speed for 1 hour in a constant temperature water bath at 50°C. Then pull out the rolling solution, the excess rolling rate is 150%, wash once with hot water at 50°C, wash twice with cold water, air-dry, and finish finishing.

[0042] The evaluation of the antimicrobial activity of the finished fabrics was carried out in accordance with "GB / T 20944.3-2008 Antibacterial Performance Evaluation of Textiles Part III: Oscillating Method".

Embodiment 2

[0044] The first step: put 2g of rabbit hair fabric into 10mL of 3% chitosan solution (bath ratio 1:5), shake at a low speed in a constant temperature water bath at 30°C. Soak the head for 30 minutes and remove it, and the excess rate of head rolling is 50%. Second dipping for 30 minutes to remove, second rolling rate of 100%.

[0045]Second step: Put the first finishing fabric into 10 mL of 2.5% glutaraldehyde solution (bath ratio 1:5), and shake at a low speed for 1 hour in a constant temperature water bath at 50°C. Then pull out the rolling solution, the excess rolling rate is 150%, wash once with hot water at 50°C, wash twice with cold water, air-dry, and finish finishing.

[0046] The evaluation of the antimicrobial activity of the finished fabrics was carried out in accordance with "GB / T 20944.3-2008 Antibacterial Performance Evaluation of Textiles Part III: Oscillating Method".

Embodiment 3

[0048] The first step: put 2g of rabbit hair fabric into 10mL of 2% chitosan solution (bath ratio 1:5), shake at a low speed in a constant temperature water bath at 30°C. Soak the head for 30 minutes and remove it, and the excess rate of head rolling is 50%. Second dipping for 30 minutes to remove, second rolling rate of 100%.

[0049] Second step: Put the first finishing fabric into 10 mL of 5% glutaraldehyde solution (bath ratio 1:5), shake in a constant temperature water bath at 50°C for 1 hour at a low speed. Then pull out the rolling solution, the excess rolling rate is 150%, wash once with hot water at 50°C, wash twice with cold water, air-dry, and finish finishing.

[0050] The evaluation of the antimicrobial activity of the finished fabrics was carried out in accordance with "GB / T 20944.3-2008 Antibacterial Performance Evaluation of Textiles Part III: Oscillating Method".

Abstract

The invention discloses a long-acting antibacterial finishing method for rabbit hair fabric, based on glutaraldehyde crosslink. The method is characterized by comprising the following finishing technical processes: firstly, preparation of finishing liquor: ensuring that finishing liquor I adopts 3 percent a chitosan solution, which is prepared from 1 percent of an acetic acid solution; and ensuring that finishing liquor II adopts 5 percent a glutaraldehyde aqueous solution; and secondly, finishing process: the first finishing process: putting 2g of rabbit hair fabric into 10mL of the finishingliquor I (with the bath ratio being 1:5), and performing low-speed vibration in a 30 DEG C thermostatic waterbath; performing first soaking for 30min, fishing out, and ensuring that the liquid fabricratio is 50 percent after the first rolling; performing second soaking for 30 min, fishing out, and ensuring that the liquid fabric ratio is 100 percent after the second rolling; and the second finishing process: putting the fabric subjected to the first finishing processing into 10mL of the finishing liquor II (with the bath ratio being 1:5), and performing low-speed vibration in a 50 DEG C thermostatic waterbath; fishing out rolling liquor, and ensuring that the liquid fabric ratio is 150 percent; washing the fabric for one time with 50 DEG C hot water, washing the fabric for two times withcold water, and performing air drying, so as to accomplish finishing. Evaluation on the antibacterial activity of the finished fabric adopts GB / T 20944.3-2008 Textiles-Evaluation for antibacterial activity-Part 3: Shake flash method.

Description

technical field [0001] The invention relates to a method for antibacterial finishing of rabbit hair fabrics, in particular to a long-acting antibacterial finishing method for rabbit hair fabrics based on glutaraldehyde crosslinking. Background technique [0002] Rabbit hair is a kind of natural protein fiber, which is composed of keratin. Compared with other commonly used natural animal fibers, rabbit hair fiber is a kind of green environmental protection, good thermal insulation material for textile, and has excellent natural characteristics. The surface of rabbit hair fiber is white, smooth and clean. It is an important raw material for textile industry, and it does not need cumbersome cleaning before textile processing, which shortens the production process and avoids the pollution of washing wastewater to the environment. Therefore, rabbit hair is used as a green Textile raw materials are more and more valued by enterprises and favored by consumers. [0003] However, ra...
