Problems solved by technology

This method is relatively simple to process, but the washing resistance and antibacterial effect persistence are poor
The third is to add antibacterial agents to spinning materials to make antibacterial fibers, and then add antibacterial finishing agents in the finishing process of fabric printing and dyeing, and then make various antibacterial textiles. This method is only used in special fabrics with high antibacterial performance requirements. used in products that limit the scope of use
[0007] Although bio-enzyme immobilization technology and 3-(trimethoxysilyl)propyl dimethyl octadecyl ammonium chloride (abbreviation: DC-5700) have been reported for finishing natural textiles, but bio-enzyme immobilization technology employs the H 2 o 2 or NaIO 4 Treat the textile with a relatively strong oxidizing agent, and then fix the lysozyme on the textile, which will damage the fiber, thereby affecting the physical properties of the textile itself (such as breaking strength)
There is a large amount of solvent methanol in the DC5700 treatment liquid, and methanol is also produced during the treatment process, which brings safety hazards to people's health

preparation example Construction

[0056] The preparation method of this organic silicon betaine is:

[0057] 1) Preparation of tertiary amine-containing organosiloxane, and reacting the tertiary amine-containing organosiloxane with reactant B for 1-48 hours under stirring in an environment at a temperature of 20-80°C to obtain a white Precipitation matter;

[0058] 2) filtering or centrifuging the above-mentioned white precipitated substance to obtain organosilicon betaine, that is, to obtain the target product;

[0059] Above-mentioned reactant B is selected from propane sultone, butane sultone, acrylic acid, β-propionolactone, X(CH 2 ) v SO 3 - , or X(CH 2 ) v CO 2 - One of, wherein X is Br, Cl or I, and v is a positive integer greater than or equal to 1.

[0060] The typical synthetic route diagram of above-mentioned preparation method is:

[0061]

[0062] In the above-mentioned preparation steps, wherein the preparation method of the organosiloxane containing tertiary amine is: take (R 1 O) ...

Abstract

The invention discloses antibiotic-mould proof textile fabric, which is obtained by attaching organic silicon betaine onto a common antibiotic-mould proof textile fabric. The preparation method comprises the following steps of: 1, soaking the textile fabric in antibiotic finishing solution or brushing or spraying the antibiotic finishing solution on the textile fabric; 2, drying or air-drying the textile fabric processed by the step 1; and 3, washing and shaping the sample obtained by the step 2, and then drying the sample to obtain the finished product. In the antibiotic-mould proof textile fabric, the organic silicon betaine is guaranteed not to be lost in a washing process and the drug resistance in microorganisms is not generated, so that the textile fabric possesses sustained and highly efficient antibiotic, mould-proof and deodorization properties and hydrophilic property, the comfort of the textile fabric is improved, and simultaneously, and the breaking strength and the elongation at break of the textile fabric are not affected; and the preparation method is simple, easily operated and controlled and suitable for industrialized production.

Description

technical field [0001] The invention relates to a textile and a preparation method thereof, in particular to an antibacterial and mildew-proof textile and a preparation method thereof. Background technique [0002] Textiles can absorb sweat, sebum and other excretions secreted by the human body. In an environment with suitable temperature and humidity, microorganisms living on textiles can reproduce in large numbers, decompose human secretions, and produce odorous substances such as ammonia. The formation of bacterial plaque can cause discomfort or adverse effects on the human body during wearing or application, causing mildew, embrittlement or even deterioration of textiles. With the development of society and the improvement of people's living standards, new market demands have emerged. Consumers hope that textiles have antibacterial functions to meet the needs of a civilized and comfortable life. In textiles, natural fibers have better moisture absorption and perspiratio...
