摘要
(US20170314187) 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
(US20170314187) We claim: 1.  A modified textile material comprising textile material and Hydroxyapatite. 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 is composed of component selected from the group comprising polyester, wool, cotton, spandex, linen and acrylic, or any combinations thereof, preferably polyester. 3. The modified textile material as claimed in claim 1, wherein the hydroxyapatite is coated on the textile material and is in sol form. 4. The modified textile material as claimed in claim 1, wherein the hydroxyapatite is embedded into grooves of said textile material. 5. 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, preferably about 1:50. 6. A process for obtaining modified textile material as claimed in claim 1, said process comprising acts of: a) treating textile material with hydroxyapatite solution to obtain treated textile material; and   b) curing the treated textile material to obtain the modified textile material. 7. The process as claimed in claim 6, wherein prior to the act of treating the textile material with the hydroxyapatite solution, the hydroxyapatite solution 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 deg. C. to about 60 deg. C., preferably about 60 deg. C.; and wherein prior to pre-heating, the hydroxyapatite solution is optionally diluted. 8. The process as claimed in claim 7, 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 deg. C. to about 85 deg. C., preferably about 85 deg. 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 deg. C. to about 85 deg. C., preferably about 85 deg. C., to obtain the hydroxyapatite solution. 9. The process as claimed in claim 8, wherein the calcium salt optionally along with its hydrated form is selected from calcium chloride and calcium nitrate tetrahydrate. 10. The process as claimed in claim 8, wherein the cationic dihydrogen phosphate, optionally along with its hydrated form is selected from sodium dihydrogen phosphate dihydrate and ammonium dihydrogen phosphate. 11. The process as claimed in claim 6, 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, preferably polyester. 12. The process as claimed in claim 6, 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 solution ranges from about 1:25 to about 1:70, preferably about 1:50. 13. The process as claimed in claim 6, wherein treating of the textile material with the hydroxyapatite solution comprises act selected from dipping and dyeing, or a combination thereof, preferably dipping; and wherein the treating results in coating of the hydroxyapatite on the textile material; and wherein the treating is carried out at temperature ranging from about 55 deg. C. to about 60 deg. C., preferably about 60 deg. C.; for time period ranging from about 45 minutes to about 1 hour, preferably about 1 hour. 14. The process as claimed in claim 6, wherein the curing is carried out for time duration ranging from about 30 minutes to about 1 hour, preferably about 1 hour; at temperature ranging from about 105 deg. C. to about 110 deg. C., preferably about 110 deg. C. 15. The process as claimed in claim 6, wherein the modified textile material is processed to obtain garment. 16. The textile assembly as claimed in claim 1, wherein the textile material selected from textile substrate, fabric or garment thereof, is bacterial repellent and odor free. 17. Use of Hydroxyapatite as a bacterial repellent. 18. The use as claimed in claim 17, 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. 19. Use of Hydroxyapatite for preparing odor free textile material selected from textile substrate, fabric or garment. 20. The use as claimed in claim 19, 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.
