Fabric anti-mite post-coating finishing
Fabric anti-mite post-coating finishing
The processing process is to immerse the pure cotton fabric made from desizing, refining, bleaching and mercerizing in a treatment liquid [75% anti-mite agent and 25% urea-formaldehyde resin] with a liquid carrying rate of 80%. Microcapsules formed by wall materials (40% slurry) account for 5%, polyurethane emulsion accounts for 0.5% (solid content 40%), and magnesium chloride accounts for 0.3%]. After rolling, dry at 120°C for 2 minutes, and then bake at 160°C for 3 minutes to obtain a product with anti-mite effect.
The anti-mite post-coating finishing method for fabrics is a conventional technology, and its implementation methods include spraying, padding, coating, etc. The key to this technology lies in the selection of anti-mite coating finishing agents and the preparation of coating finishing agents. It can be seen from the relevant Japanese patent introduction that large textile companies such as Teijin, Kuraray, Mitsubishi Rayon, Toyobo Corporation, and many dyeing and finishing companies have participated in the development of this anti-mite fabric.
Secondly, dissolve the anti-mite coating finishing agent in the “shale tar A” solvent, use sorbic acid sol 2942S, heptane melt 100 and calcium dodecyl benzene sulfonate as emulsifiers, and stir thoroughly to form a uniform anti-mite coating. Mite Coating Finisher Lotion. The anti-mite coating finishing agent emulsion is then mixed with a latex liquid of polyacrylonitrile resin, polyester resin, and polyurethane to obtain an anti-mite treatment liquid. The method of treating fabrics with anti-mite treatment liquid is as follows: Dip 30 square centimeters of cotton and polyester/nylon (65:35) blended fabric into 200 mL of anti-mite treatment liquid. Use a mangle to dry it until the liquid content is 80%, then dry it at 80°C for 5 minutes, and then heat treat it at 130°C for 1 minute. After such treatment, the fibers and their fabrics can be given washing resistance.
In addition, the emulsion of isocyanothioacetate and the emulsion of polyester copolymer can also be used in the same bath to obtain an anti-mite effect with washability. The polyester copolymer is emulsified and dispersed in water with nonionic or anionic surfactants to form an emulsion. As an anti-mite coating finishing agent, isocyanothioacetate is emulsified and dispersed in water with a nonionic or anionic surfactant to form an emulsion. The polyester fabric is padded (liquor rate 80%), dried (100°C), and then heat treated at 180°C for 1 to 2 minutes to improve the anti-mite effect and washability.
Which kind of anti-mite fabric is good?
The anti-mite and antibacterial finishing agent has good safety, broad-spectrum and efficient anti-mite and antibacterial properties and excellent washing resistance. It is the nemesis of germs and mites and has a protective effect on tracheal asthma caused by mite allergy.
It is suitable for anti-mite and antibacterial finishing of cotton, linen, silk, wool, polyester-cotton, nylon, viscose and other fabrics. Such as the production of bedding, underwear, towels, knitwear, carpets, sofas, interior decoration products, etc. with anti-mite, antibacterial, deodorant, and anti-mildew functions. It has no adverse effects on the whiteness, color, strength, feel and moisture absorption and breathability of the fabric.
The Chinese People’s Liberation Army Academy of Military Medical Sciences, China Center for Disease Control, China Medical Laboratory Center, ITS, SGS and many other authoritative health units have tested and applied it to prove that anti-mite and antibacterial fabrics are non-toxic and have no allergic reaction to the skin. The repellent rate for dust mites, leather mites, chiggers, and demodex is over 93%, and it can completely kill Neisseria gonorrhoeae (941748 domestic epidemic strains), Neisseria gonorrhoeae (WHOQ61 international standard drug-resistant strain), and Staphylococcus aureus (ATCC6389), Escherichia coli (ATCC8099), Candida albicans (ATCC10231), Microsporum gypsum, Epidermophyton floccosum, Trichophyton rubrum, Bacillus subtilis nigricans (ATCC9372) and other more than 20 kinds of harmful bacteria The antibacterial rate is as high as over 99%, and it is highly resistant to dry cleaning and water washing; it is non-irritating to the skin, has no allergic reactions, is non-toxic, non-teratogenic, non-mutagenic, non-potential carcinogenic, and does not contain formaldehyde and heavy metal ions, etc. Hazardous substances, in line with environmental protection requirements, and meets the Oeko-Texstand100 standard; it can effectively prevent disease transmission through fabrics. v6P71nue9
