Deodorizing spandex and manufacturing method therefor

Abstract

The present invention relates to a deodorizing spandex and a manufacturing method therefor, the deodorizing spandex comprising: an inorganic deodorant comprising at least any one selected from zirconium phosphate (Zr-phosphate), a composite metal oxide, or at least one of metal oxides selected from Zn, Si, Mg or Al; and a wet dispersant.

1 . A deodorant spandex prepared by comprising an inorganic deodorant, including at least any one selected from a metal phosphate containing Zr or a metal oxide or a composite metal oxide selected from at least one or more of Zn, Si, Mg or Al; and a wet dispersant. 
     
     
         2 . The deodorant spandex according to  claim 1 , wherein the deodorant spandex comprises an inorganic deodorant added in an amount of 1.0˜10 wt % with respect to solid content of a deodorant spandex yarn and a wet dispersant added in an amount of 1 to 17 wt % with respect to the inorganic deodorant. 
     
     
         3 . The deodorant spandex according to  claim 1 , wherein the metal phosphate containing Zr is any one selected from ZrP 2 O 7 , (ZrO) 2 P 2 O 7  or ZrO(H 2 PO 4 ) 2 , the metal oxide is ZnO or SiO 2 , and the composite metal oxide contains two or more metals selected from Zn, Si, Mg, or Al, or at least two or more metals including one metal selected from Zn, Si, Mg, or Al and other metal of Cu, Ni or Fe. 
     
     
         4 . The deodorant spandex according to  claim 1 , wherein the wet dispersant is any one selected from DISPERBYK-110, 111, 162; 164, 168; 180 or 185. 
     
     
         5 . A method of preparing a deodorant spandex, comprising the steps of: adding 1.0-10 wt % of an inorganic deodorant with respect to a solid content of a polymer for preparing a spandex including at least any one selected from a metal phosphate containing Zr or a metal oxide or a composite metal oxide selected from at least one or more of Zn, Si, Mg or Al; adding 1 to 17 wt % of a wet dispersant with respect to the inorganic deodorant; adding other additives including at least one of an antioxidant, a yellowing inhibitor, a quencher, an anti-adhesive agent, a function-improving agent, or dye enhancer; characterized in that it is added to a spandex polymer in slurry form through a milling process. 
     
     
         6 . The method according to  claim 5 , wherein the inorganic deodorant, the wet dispersant and other additives are mixed, then prepared into slurry form through a milling process and added to the spandex polymer. 
     
     
         7 . The method according to  claim 5 , wherein the additives are prepared in slurry form through a milling process and added to the spandex polymer, then the inorganic deodorant and the wet dispersant are mixed and added in slurry form to the spandex polymer which has the other additives in the slurry form added thereto. 
     
     
         8 . The method according to  claim 5 , wherein the metal phosphate containing Zr is any one selected from ZrP 2 O 7 , (ZrO) 2 P 2 O 7  or ZrO(H 2 PO 4 ) 2 , the metal oxide is ZnO or SiO 2 , and the composite metal oxide contains two or more metals selected from Zn, Si, Mg, or Al, or at least two or more metals including one metal selected from Zn, Si Mg, or Al and other metal of Cu, Ni or Fe. 
     
     
         9 . The method according to  claim 5 , wherein the wet dispersant is any one selected from DISPERBYK-110, 111, 162, 164, 168, 180 or 185.
