Problems solved by technology

[0003] With the improvement of science and technology level and the emergence of nanotechnology, compared with traditional antibacterial agents, nano-antibacterial agents are more widely known, efficient and safe, but the disadvantage is that the binding force between nano-inorganic antibacterial agents and substrates is weak, easy to The organic silicon quaternary ammonium salt has excellent antibacterial properties, and its active reactive group can form a strong covalent bond with the substrate, which is washable, durable and not easy to fall off, but its defect is only for negative belts. Bacteria are inhibited

Embodiment 1

[0036] A preparation method of antibacterial and anti-mite cotton fiber, comprising the steps of:

[0037] first step:

[0038] The cotton fiber is subjected to surface oil and fruit wax removal treatment in clean water at a temperature of 90°C for 60 minutes and then washed;

[0039] Step two:

[0040] Completely soak the absorbent cotton product obtained in the first step into an aqueous solution with a mass fraction of 2% trimethoxysilane, heat it in a water bath at a temperature of 60° C. to obtain a cotton fiber suspension and keep it warm for 2 hours after fully stirring for 30 minutes;

[0041] third step:

[0042] The cotton fiber suspension is added to a mixed solution with a concentration of 5% dimethyl octadecyl ammonium chloride and a concentration of 8% propylene glycol and stirred; when heated to 80°C, an appropriate amount of 5% by mass fraction The citric acid was incubated for 3 hours, then dried at a constant temperature of 80°C for 60 minutes and cooled t...

Embodiment 2

[0049] A preparation method of antibacterial and anti-mite cotton fiber, comprising the steps of:

[0050] first step:

Abstract

The invention discloses a preparation method of a long-acting antibacterial anti-mite cotton fiber. The preparation method of the long-acting antibacterial anti-mite cotton fiber is characterized by comprising the following steps of (1) preparing absorbent cotton; (2) preparing a cotton fiber suspension; (3) carrying out binding reaction on organosilicon quaternary ammonium salt and the cotton fiber; (4) carrying out silver ion catalytic reaction; and (5) filtering and washing. The antibacterial and anti-mite cotton fiber prepared by the preparation method provided by the invention has the antibacterial rate of more than 99 percent for staphylococcus aureus, escherichia coli, candida albicans, klebsiella pneumoniae and the like, has the antibacterial rate of more than 99 percent for fungi such as trichophyton rubrum (dermatophytosis) and the like, has the repelling rate of more than 95 percent for dermatophagoides farinae according to the national standard GB / T 24253-2009 Evaluation of Textile Anti-mite Performance, and achieves a very strong anti-mite effect.

Description

technical field [0001] The invention relates to the field of natural cellulose fiber preparation, in particular to a preparation method of antibacterial and anti-mite cotton fiber and its product. Background technique [0002] In our daily life, people come into contact with many bacteria, fungi, viruses, and microorganisms every day. Many microorganisms are harmful to the human body. Infectious diseases such as influenza and skin diseases such as tinea pedis that occur every year are caused by bacteria and Viruses can seriously affect people's health and even life. Especially the textiles that are worn and used every day are very easy to breed germs. Mites are the living hotbeds of microorganisms and an important source of disease transmission. Mites can damage the skin and cause inflammation of skin hair follicles. Mites can also cause infectious diseases to spread after biting the human body; The demand for antibacterial and anti-mite textile materials is becoming strong...
