Multilayer coated multicolor yarn and manufacturing method thereof

Abstract

The multilayer coated multicolor yarn according to the present invention is part-colored and exposes various colors on the surface of the yarn, and, therefore, a fabric woven by the inventive yarn gives a unique aesthetic feeling. In addition, due to the multiple urethane coating layers, the yarn has excellent abrasion resistance, mechanical properties, durability, thermoformability and adhesion property.

What is claimed is: 
     
         1 . A multilayer coated multicolor yarn comprising a core yarn, a first coating layer formed on the core yarn and a second coating layer formed on the first coating layer, wherein at least a part of the first coating layer is not covered by the second coating layer so that each colors of the first and second coating layers appear at the surface of the multilayer coated multicolor yarn. 
     
     
         2 . The multilayer coated multicolor yarn of  claim 1 , further comprising a third coating layer formed on the second coating layer, at least a part of the second coating layer is not covered by the third coating layer and at least a part of the first coating layer not covered by the second coating layer is not covered by the third coating layer so that each colors of the first, the second and third coating layers appear at the surface of the multilayer coated multicolor yarn. 
     
     
         3 . The multilayer coated multicolor yarn of  claim 2 , further comprising an additional coating layer on the third coating layer, wherein each colors of the coating layers appear at the surface of the multilayer coated multicolor yarn. 
     
     
         4 . The multilayer coated multicolor yarn of  claim 1 , wherein the multilayer coated multicolor yarn color yarn is a twisted yarn twisted with a rotational speed of 1,000 to 10,000 rpm. 
     
     
         5 . A method for preparing the multilayer coated multicolor yarn of  claim 1 , comprising the steps of coating a first resin composition including a first pigment on the surface of the core yarn and drying the first resin composition to form the first coating layer on the core yarn; coating a second resin composition including a second pigment on the first coating layer to form the second coating layer; removing a part of the second coating layer so that the first coating layer is partially exposed to the outside; and drying the second coating layer. 
     
     
         6 . The method of  claim 5 , further comprising coating a third resin composition after drying the second coating layer; removing a part of the third coating layer so that the first and second coating layers are partially exposed to the outside; and drying the third coating layer. 
     
     
         7 . The method of  claim 6 , wherein a part of the second coating layer or the third coating layer is removed by scraping a part of the second or third coating layer before drying the second or third coating layer. 
     
     
         8 . The method of  claim 7 , wherein a part of the coating layer is scraped by making a coated yarn discharging from an outlet of a coater contact with an edge of the coater outlet at a predetermined angle by using a roller. 
     
     
         9 . The method of  claim 8 , wherein the roller is an eccentric roller and the coated yarn contacts with the edge of the coater outlet at different points. 
     
     
         10 . The method of  claim 8 , wherein the roller is mounted on a rotatable means which is rotatable at 360 degrees with respect to the center axis of the coater outlet, the coated yarn discharging from the coater is in contact with the circumference of the outlet edge. 
     
     
         11 . The method of  claim 5 , further comprising twisting finally dried coated yarn. 
     
     
         12 . The method of  claim 6 , further comprising twisting finally dried coated yarn.
