Method of manufacturing stab-resistant fabric using water punching

Abstract

A method of manufacturing stab-resistant fabric using water punching is provided. Aramid fabric and nonwoven aramid fabric are combined through water punching, thereby enhancing activities by ensuring flexibility and stab-resistance performance, and the method is an aramid composite fabric manufacturing method which performs water punching with pressure of 50 to 250 bar when the water punching is performed.

What is claimed is: 
     
         1 . A method of manufacturing stab-resistant fabric using water punching, comprising:
 interlacing an aramid nonwoven fabric in a high strength fabric formed of aramid yarn through water punching.   
     
     
         2 . The method of  claim 1 , wherein a tissue of the high strength fabric is a tissue selected from plain fabric and twilled fabric. 
     
     
         3 . The method of  claim 1 , wherein the aramid yarn is spun yarn 40/3 (tex 40/strands 3) to 60/2 or 500 to 600 denier filament yarn. 
     
     
         4 . The method of  claim 1 , wherein the density of the fabric is 30×30 ply (wrap threads×weft threads) to 85×85 ply (wrap threads×weft threads)/5 cm, a basic weight is 100 to 200 gsm, and air permeability is 5 cm 3 /cm 2 /s or greater. 
     
     
         5 . The method of any one of  claim 1 , wherein the nonwoven fabric is formed of aramid fiber having fineness of 3 to 6 denier, and has a basic weight of 40 to 70 gsm and air permeability of 100 cm 3 /cm 2 /s or greater. 
     
     
         6 . The method of any one of  claim 2 , wherein the nonwoven fabric is formed of aramid fiber having fineness of 3 to 6 denier, and has a basic weight of 40 to 70 gsm and air permeability of 100 cm 3 /cm 2 /s or greater. 
     
     
         7 . The method of any one of  claim 3 , wherein the nonwoven fabric is formed of aramid fiber having fineness of 3 to 6 denier, and has a basic weight of 40 to 70 gsm and air permeability of 100 cm 3 /cm 2 /s or greater. 
     
     
         8 . The method of any one of  claim 4 , wherein the nonwoven fabric is formed of aramid fiber having fineness of 3 to 6 denier, and has a basic weight of 40 to 70 gsm and air permeability of 100 cm 3 /cm 2 /s or greater. 
     
     
         9 . The method of any one of  claim 1 , wherein the water punching is performed with water pressure of 50 to 250 bar. 
     
     
         10 . The method of any one of  claim 2 , wherein the water punching is performed with water pressure of 50 to 250 bar. 
     
     
         11 . The method of any one of  claim 3 , wherein the water punching is performed with water pressure of 50 to 250 bar. 
     
     
         12 . The method of any one of  claim 4 , wherein the water punching is performed with water pressure of 50 to 250 bar.
