High-strength and tear-resistant fabric

Abstract

A high-strength and tear-resistant fabric includes a first fabric yarn made of polyester filament yarn and a second fabric yarn made of a composite yarn including polyethylene filament yarn and polyester filament yarn. The fabric has a mass percentage of polyethylene filament yarn between 15% and 50%. When the second fabric yarn is a twisted or untwisted composite yarn and the mass percentage of polyethylene filament yarn in the fabric is approximately 20% to 25%, the resulting fabric exhibits exceptionally ideal strength and tear-resistant characteristics while effectively reducing the production cost of the fabric.

What is claimed is: 
     
         1 . A high-strength and tear-resistant fabric, comprising:
 a first fabric yarn, the first fabric yarn being made of polyester filament yarn; and   a second fabric yarn, the second fabric yarn being a composite yarn comprising polyethylene filament yarn and polyester filament yarn;   wherein a mass percentage of the polyethylene filament yarn in the fabric is not less than 15% and not greater than 50%.   
     
     
         2 . The high-strength and tear-resistant fabric according to  claim 1 , wherein an elongation of the fabric is 1% to 10%. 
     
     
         3 . The high-strength and tear-resistant fabric according to  claim 1 , wherein the polyethylene filament yarn is a high-performance polyethylene filament. 
     
     
         4 . The high-strength and tear-resistant fabric according to  claim 3 , wherein the high-performance polyethylene filament is an ultra-high molecular weight polyethylene filament. 
     
     
         5 . The high-strength and tear-resistant fabric according to  claim 1 , wherein the first fabric yarn is a warp yarn and the second fabric yarn is a weft yarn. 
     
     
         6 . The high-strength and tear-resistant fabric according to  claim 5 , wherein the second fabric yarn is an untwisted composite yarn. 
     
     
         7 . The high-strength and tear-resistant fabric according to  claim 6 , wherein the untwisted composite yarn has a polyester filament yarn as a core and a polyethylene filament yarn as a covering, and the covering at least partially covers the core. 
     
     
         8 . The high-strength and tear-resistant fabric according to  claim 7 , wherein the core is composed of at least one polyester filament yarn, and/or the covering is composed of at least one polyethylene filament yarn. 
     
     
         9 . The high-strength and tear-resistant fabric according to  claim 1 , wherein the second fabric yarn is a twisted composite yarn. 
     
     
         10 . The high-strength and tear-resistant fabric according to  claim 9 , wherein the polyethylene filament yarn in the twisted composite yarn is at least one filament, and/or the polyester filament yarn is at least one filament. 
     
     
         11 . The high-strength and tear-resistant fabric according to  claim 10 , wherein the polyethylene filament yarn and the polyester filament yarn in the second fabric yarn are twisted in an “S” or “Z” direction. 
     
     
         12 . The high-strength and tear-resistant fabric according to  claim 8 , wherein when the second fabric yarn is an untwisted composite yarn or a twisted composite yarn, a mass percentage of the polyethylene filament yarn in the second fabric yarn is 40% to 57%. 
     
     
         13 . The high-strength and tear-resistant fabric according to  claim 12 , wherein a linear density of the polyethylene filament yarn is 60 to 400 denier, and the linear density of the polyester filament yarn is 900 to 1000 denier. 
     
     
         14 . The high-strength and tear-resistant fabric according to  claim 13 , wherein the mass percentage of the polyethylene filament yarn in the fabric is 20% to 25%. 
     
     
         15 . The high-strength and tear-resistant fabric according to  claim 14 , wherein the fabric is a webbing. 
     
     
         16 . The high-strength and tear-resistant fabric according to  claim 15 , wherein the webbing is a woven webbing or a knitted webbing.
