Abstract

A method of treating a textile fabric and a textile fabric having anti-microbial and durable wash properties comprising a textile substrate and one or more disinfecting agents, anti-viral agents, anti-fungal agents and emulsifying agents that are applied with one or more of an exhaust, padding, coating or spraying process and dried using a heat setting process.

Claims

1. A method of treating a textile substrate comprising:

applying a disinfecting treating composition comprising at least one compound selected from the group consisting of a quaternary ammonium organosilane compound, a silver salt, poly-glucosamine, propiconazole, biocoated silver particles, polyhexamethylene biguanide and combinations thereof using one or more of an exhaust, padding, coating or spraying process, wherein the treating composition comprises an antifungal agent which is at least one selected from the group consisting of thiabendazoles or propiconazoles and combinations thereof in a concentration range of between 0.5 ppm to 200 ppm and further comprises a cross-linking agent, which is selected from a type of adducts of, blocked isocyanate and is used in a concentration range of between 1 ppm to 300 ppm; and

drying the textile substrate using a heat setting process.

2. The method of claim 1, wherein the textile substrate is made of a natural textile or a synthetic textile that is woven, knitted, crocheted, bonded or non-woven.

3. The method of claim 2, wherein the textile substrate is made from a yam that is spun, electrospun, drawn or extruded, where the natural textile is at least one selected from the group consisting of wool, cotton, silk, linen, hemp, ramie and jute or the synthetic textile is at least one selected from the group consisting of rayon, nylon, non-acrylic olefin, acrylic polyester, PTFE, PP, PPE, carbon fiber, vinyon, polyvinylidene chloride (PVDC), spandex, vinalon, aramids, modal, sulfar, polybenzimidazole fibre, PLA, lyocell, polyacrylonitrile, fiber spun from a liquid crystal polymer (LCP) being an aromatic polyester produced by polycondensation of 4-hydroxybenzoic acid and 6-hydroxynaphthalene-2-carboxylic acid, and poly(p-phenylene-2,6-benzobisoxazole, acrylonitrile, and combinations thereof.

4. The method of claim 3, wherein the textile substrate is blended.

5. The method of claim 1, wherein the disinfecting treating composition is used in a concentration range of between 0.1 to 10%.

6. The method of claim 1, wherein a quaternary ammonium organosilane has the molecular structure

7. The method of claim 6, wherein the organosilane is an octadecylaminomethyl trihydroxysilylpropyl ammonium chloride, used in the range of 5 to 50 gram by weight.

8. The method of claim 1, wherein the silver salt of the treating composition is used in the range of 0.1% to 5%, and the polyhexamethylene biguanide (PHMB) is used in the range of 1 to 2% by weight.

9. The method of claim 1, wherein the treating composition further comprises an antiviral agent that is selected from the group consisting of compound methyl alcohol, octadecylaminomethyl trihydroxysilylpropyl ammonium chloride and chloropropyl trihydroxysilane, polyglucosamine, silver chloride based compound and silver chloride in aluminosilicate carrier base and polyhexamethylene biguanide and combinations thereof, in a concentration range of between 1 ppm to 500 ppm, and the polysaccharide or oligosaccharide or biocoated silver nanoparticles, in a concentration range of between 0.1 ppm to 150 ppm.

10. The method of claim 1, wherein the treating composition further comprises an emulsifying agent which is at least one selected from the group consisting of polyoxyethylene monostearate, polyoxyethylene sorbitan monolaurate, and polyethylene glycol 400 monolaurate and combinations thereof and is used in a concentration of between 0.1 ppm to 200 ppm.

11. The method of claim 1, wherein water, or any other solvent which is compatible with the at least one compound of the disinfecting treating composition, the antifungal agent and the cross-linking agent is added to create the treating composition.

12. The method of claim 1, wherein the treating composition further comprises at least one treating agent selected from the group consisting of water and oil repellents, abrasion resistant agents, antistatic agents, anti-pilling agents, easy care resins, wetting agents, wicking chemicals, softeners, mosquito repellants, UV protectors, soil releasing agents, viscosity modifiers, pH modifiers, emulsifying agents and combinations thereof.

13. The method of claim 1 further comprising passing the treated textile substrate through a stenter frame which provides heat of between 110°

C.−

180°

C. with a dwell time of between 1-7 minutes.

14. The method of claim 13, further comprising passing the textile substrate once again through the stenter frame for drying at a temperature of 110°

C.−

180°

C. with a dwell time of between 1-7 minutes, in order to penetrate the solution completely into the textile and complete polymerization.

15. The method of claim 1, further comprising

forming the disinfecting treating composition as a liquor;

and

spraying the liquor on the textile substrate for a specific time and in temperature range of 20-90 degrees Centigrade.
