摘要
(US10508386) The present disclosure relates to modified textile material, wherein the modification is carried out by treating textile material with Hydroxyapatite. Such modified textile materials show bacterio-repulsion by preventing bacteria from attaching to their surfaces, thereby preventing malodor formation. The present disclosure also relates to process for obtaining the modified textile material as well as use of Hydroxyapatite as a bacterial repellent agent for preparing odor free textile material.

主权利要求
(US10508386) We claim: 1. A modified textile material consisting of textile material and Hydroxyapatite, wherein the Hydroxyapatite is coated on the textile material and is in sol form. 2. The modified textile material as claimed in claim 1, wherein the textile material is selected from textile substrate, fabric or garment; and wherein the textile material comprises a component selected from the group comprising polyester, wool, cotton, spandex, linen and acrylic, or any combinations thereof. 3. The modified textile material as claimed in claim 1, wherein the hydroxyapatite is embedded into grooves of said textile material. 4. The modified textile material as claimed in claim 1, wherein the hydroxyapatite has particle size ranging from about 700 nm to about 2500 nm and nano spiky ends having width ranging from about 15 nm to about 30 nm; and wherein the ratio of the textile material to the Hydroxyapatite ranges from about 1:25 to about 1:70. 5. A process for obtaining the modified textile material as claimed in claim 1, said process comprising acts of:   a) coating a textile material with a hydroxyapatite sol to obtain a coated textile material; and   b) curing the coated textile material to obtain the modified textile material. 6. The process as claimed in claim 5, wherein prior to the act of coating the textile material with the hydroxyapatite sol, the hydroxyapatite sol is prepared by hydrolysis of calcium salt and cationic dihydrogen phosphate, optionally along with their hydrated form in alkaline water and pre-heated at temperature ranging from about 55° C. to about 60° C.; and wherein prior to pre-heating, the hydroxyapatite sol is optionally diluted. 7. The process as claimed in claim 6, wherein the hydrolysis comprises acts of:   a) adding about 20 ml to about 25 ml of ammonia solution dropwise to about 20 ml to about 25 ml solution of the calcium salt and the cationic dihydrogen phosphate, optionally along with their hydrated form, under stirring at temperature ranging from about 80° C. to about 85° C.; for time duration ranging from about 1 hour to about 2 hours, to obtain milky solution; and   b) stirring the milky solution for time period raging from about 0.5 hours to about 1 hour, preferably about 1 hour; at temperature ranging from about 80° C. to about 85° C. to obtain the hydroxyapatite sol. 8. The process as claimed in claim 7, wherein the calcium salt optionally along with its hydrated form is selected from calcium chloride and calcium nitrate tetrahydrate. 9. The process as claimed in claim 7, wherein the cationic dihydrogen phosphate, optionally along with its hydrated form is selected from sodium dihydrogen phosphate dihydrate and ammonium dihydrogen phosphate. 10. The process as claimed in claim 5, wherein the textile material is selected from textile substrate, fabric or garment; and the textile material is composed of component selected from the group comprising polyester, wool, cotton, spandex, linen and acrylic, or any combinations thereof. 11. The process as claimed in claim 5, wherein the hydroxyapatite has particle size ranging from about 700 nm to about 2500 nm and nano spiky ends having width ranging from about 15 nm to about 30 nm; and wherein ratio of the textile material to the hydroxyapatite sol ranges from about 1:25 to about 1:70. 12. The process as claimed in claim 5, wherein coating of the textile material with the hydroxyapatite sol comprises an act selected from dipping and dyeing, or a combination thereof; and wherein the coating is carried out at temperature ranging from about 55° C. to about 60° C.; for time period ranging from about 45 minutes to about 1 hour, preferably about 1 hour. 13. The process as claimed in claim 5, wherein the curing is carried out for time duration ranging from about 30 minutes to about 1 hour; at temperature ranging from about 105° C. to about 110° C. 14. The process as claimed in claim 5, wherein the modified textile material is processed to obtain a garment. 15. The modified textile material as claimed in claim 1, wherein the modified textile is a material selected from textile substrate, fabric or garment thereof, and is bacterial repellent and odor free. 16. The modified textile material as claimed in claim 2, wherein the textile material is polyester. 17. The modified textile material as claimed in claim 4, wherein the ratio of the textile material to the Hydroxyapatite is about 1:50. 18. The modified textile material as claimed in claim 1, wherein the modified textile material does not cause harm to skin flora.
