High-tenacity circular fabric made of normal yarn rather than high tenacity yarn

Abstract

Disclosed is a high-tenacity circular fabric made of normal yarn rather than high-tenacity yarn. The high-tenacity circular fabric has a weight in a range of 150 g/sqm to 400 g/sqm and is woven with yarn having strength in a range of 3 g/den to 6 g/den, wherein the yarn is woven into the high-tenacity circular fabric by a circular knitting machine, and a cam of the circular knitting machine is formed with grooves which are sequentially formed according to arrangement of a running position, a clearing position, a modified running position, a tuck position and a knock-over position.

What is claimed is: 
     
         1 . A high-tenacity circular fabric made of normal yarn rather than high-tenacity yarn, wherein the high-tenacity circular fabric has a weight in a range of 150 g/sqm to 400 g/sqm and woven with yarn having strength in a range of 3 g/den to 6 g/den,
 wherein the yarn is woven into the high-tenacity circular fabric by a circular knitting machine, and   wherein a cam of the circular knitting machine is formed with grooves which are sequentially formed according to arrangement of a running position, a clearing position, a modified running position, a tuck position and a knock-over position.   
     
     
         2 . The high-tenacity circular fabric of  claim 1 , wherein a needle is connected to the groove and moves along positions of the grooves to perform a weaving work, and
 wherein, when the needle moves to the running position, the clearing position, the modified running position, the tuck position and the knock-over position, first feeding yarn is formed in rear of second feeding yarn to form a first loop and previous yarn is formed in front of the second yarn to form a second loop.   
     
     
         3 . The high-tenacity circular fabric of  claim 1 , wherein the yarn has radial tensile strength in a range of 30 kgf/30 mm to 90 kgf/30 mm, lateral tensile strength in a range of 25 kgf/30 mm to 75 kgf/30 mm, radial internal tearing strength in a range of 3.5 kgf to 10.5 kgf and lateral internal tearing strength in a range of 3.0 kgf to 9.0 kgf. 
     
     
         4 . The high-tenacity circular fabric of  claim 2 , wherein the yarn has radial tensile strength in a range of 30 kgf/30 mm to 90 kgf/30 mm, lateral tensile strength in a range of 25 kgf/30 mm to 75 kgf/30 mm, radial internal tearing strength in a range of 3.5 kgf to 10.5 kgf and lateral internal tearing strength in a range of 3.0 kgf to 9.0 kgf.
