Embodiment 1

[0026] A method for making wool fabrics have antibacterial and antistatic properties, the specific steps of which are:

[0027] (1) Synthesis of Gemini quaternary ammonium salt IDMA:

[0028] a. Weigh 4.083g of white powder BbmBP into a 250mL three-neck flask, add acetone drop by drop, and stir while adding, until the white solid is just completely dissolved. Fix the three-necked flask on the iron clip of the heat-collecting electromagnetic stirrer, add 4.764g DMAEMA in the dropping funnel, and add dropwise to the three-necked flask. After the dropwise addition, the temperature was raised to 50° C., and the reaction was stirred under reflux for 24 hours.

[0029] b. After the reaction is complete, take out the product, filter it with a suction filter bottle, and wash and filter it with acetone and carbon tetrachloride respectively to obtain a white solid, which is the relatively pure Gemini quaternary ammonium salt IDMA.

[0030] c. drying the synthesized product after sucti...

Embodiment 2

[0040] A method for making wool fabrics have antibacterial and antistatic properties, the specific steps of which are:

[0041] (1) Synthesis of Gemini quaternary ammonium salt IDMA:

[0042] a. Weigh 6.125g of white powder BbmBP into a 250mL three-neck flask, add acetone dropwise, and stir while adding, until the white solid is just completely dissolved. Fix the three-necked flask on the iron clip of the heat-collecting electromagnetic stirrer, add 7.146g of DMAEMA into the dropping funnel, and add dropwise to the three-necked flask. After the dropwise addition, the temperature was raised to 55° C., and the reaction was stirred under reflux for 18 hours.

[0043] b. After the reaction is complete, take out the product, filter it with a suction filter bottle, and wash and filter it with acetone and carbon tetrachloride respectively to obtain a white solid, which is the relatively pure Gemini quaternary ammonium salt IDMA.

[0044] c. drying the synthesized product after suctio...

Abstract

The invention relates to a new effective and lasting method for making wool fabric have the antibacterial and anti-static functions. According to the method, firstly Gemini quaternary ammonium salt IDMA is synthesized, the synthesized product is detected and analyzed through infrared spectroscopy, 1H-NMR analysis, mass spectrometry and element analysis, and it is determined that the product is a target product; then, tris(2-carboxyethyl) phosphine is used for pre-processing wool fabric, and disulfide bonds in keratin of wool fibers are ruptured so that high-activity sulfhydryl groups can be formed; finally, the wool fabric where TCEP pre-processing is performed is soaked in an IDMA configured solution, C=C in IDMA molecules and S-H on wool protein molecules react through click chemistry, and IDMA quaternary ammonium salt is introduced into the wool protein molecules through a chemical bonding method. The processed wool fabric has the antibacterial and anti-static functions. The processing method is easy to operate, excellent in performance, lasting in effect and can improve the mechanical strength of the fabric.

Description

technical field [0001] The present invention relates to an effective and environmentally friendly new method for imparting antibacterial and antistatic properties to wool fabrics. Background technique [0002] Wool is a natural fiber with excellent wearing properties, and has excellent properties in terms of elasticity, moisture absorption, warmth, stain resistance, gloss biodegradation and compatibility. With the continuous improvement of living standards, people's demand for product functions has changed to functions such as comfort, health, safety, easy care and health care. Wool plays an increasingly important role in the fields of automobiles, medical and aerospace. [0003] As a protein fiber, wool is often used as a source of nutrition for bacteria and worms. Under the right humidity and temperature, wool and silk will become a medium for the growth and spread of microorganisms, and produce unpleasant odors, fade colors, and degrade fabrics. and spread disease. Ther...
