Method for coating knitted fabric

Abstract

A method for coating a knitted fabric includes the following steps of: attaching a knitted fabric flatly onto a carrier sheet to form a laminate, the carrier sheet having a tensile strength greater than that of the knitted fabric; forming a coating layer onto a top surface of the knitted fabric; and separating the knitted fabric with the coating layer from the carrier sheet.

1 . A method for coating a knitted fabric, comprising the following steps of:
 (a) attaching a knitted fabric flatly onto a carrier sheet to form a laminate, the carrier sheet having a tensile strength greater than that of the knitted fabric;   (b) forming a coating layer onto a top surface of the knitted fabric; and   (c) separating the knitted fabric with the coating layer from the carrier sheet.   
     
     
         2 . The method of  claim 1 , wherein step (b) is conducted by passing the laminate through a coating machine. 
     
     
         3 . The method of  claim 1 , further comprising a step (a1) of trimming edges of the knitted fabric after step (a). 
     
     
         4 . The method of  claim 1 , wherein, in step (a), the knitted fabric is attached to the carrier sheet by adhesives. 
     
     
         5 . The method of  claim 1 , wherein, in step (a), the knitted fabric is attached to the carrier sheet by sewing. 
     
     
         6 . The method of  claim 1 , wherein, in step (a), the knitted fabric is attached to the carrier sheet by high-frequency thermal bonding. 
     
     
         7 . The method of  claim 2 , wherein, in step (b), the laminate is driven by at least one roller to pass through the coating machine. 
     
     
         8 . The method of  claim 1 , wherein, in step (b), the coating layer is formed by roller coating. 
     
     
         9 . The method of  claim 1 , wherein, in step (b), the coating layer is formed by knife-over-roll coating. 
     
     
         10 . The method of  claim 1 , wherein, in step (b), the coating layer is formed by blade coating. 
     
     
         11 . The method of  claim 1 , wherein, in step (b), the coating layer is formed by foam coating. 
     
     
         12 . The method of  claim 1 , wherein, in step (b), the coating layer is composed of a functional coating material that is selected from, the group consisting of polyurethane resin, polymethylmethacrylate resin, rubber, pigment, polyvinylchloride adhesive, colored adhesive, waterproof breathable adhesive, and combinations thereof. 
     
     
         13 . The method of  claim 1 , wherein, in step (a), the carrier sheet is a woven fabric.
