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 baki

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.
