Structure of touch-fastening anti-skidding material

Abstract

A touch-fastening anti-skidding material includes a knitted foundation layer and a plurality of synthetic yarns that is secured together by being collectively knitted in the foundation layer. The foundation layer is formed by knitting of pliable base yarns and synthetic yarns. The synthetic yarns are knitted in U-shaped loops and the base yarns are knitted between adjacent strands of the knitted synthetic yarns to make a large area cloth. The cloth may be in a planar form without hollow opening sections or it includes open sections to facilitate air permeability. The loops of the synthetic yarns have legs extending beyond the foundation layer by a predetermined length and the synthetic yarns show rigidity strength, whereby a flexible, resilient, light-weighted, and low-cost touch-fastening anti-skidding material is formed.

I claim: 
     
         1 . A touch-fastening anti-skidding material comprising a foundation layer that is formed by knitting a plurality of synthetic yams and pliable yams knitted together to form multiple layers that are each on a horizontal plane and stacked in a vertical direction and connected by the synthetic yams extending thereby and then cutting and separating the stacked layers to provide individual foundation layers, the knitting of each of the individual foundation layers being in such a way that each of said synthetic yams is accompanied by a respective one of said pliable yams, said synthetic yams and said pliable base yams being knitted on a common plane to form said foundation layer, each of the synthetic yams having a monofilament diameter φ range between 0.02 mm-0.5 mm and having a hardness between Shore D: 40 D-90 D to provide said synthetic yams with rigidity strength, said synthetic yams forming loops each having two outward-extending legs that have free ends, said loops being linked to each other so that a rear one of said loops is set to loop around a front one of said loops to form rows of loops each extending in a front-rear direction with the rows being exclusively arranged on the common horizontal plane to juxtapose each other in a transverse direction that is substantially normal to the front-rear direction and on the same horizontal plane, said free ends of said two legs extending out of said foundation layer in the vertical direction substantially perpendicular to the common horizontal plane, said pliable yarns being arranged to parallel accompany said synthetic yarns in such a way that said pliable yarns, after co-bent with said synthetic yarns to form loops, are set to individually and transversely extend to and subsequently parallel accompany an adjacent strand of said synthetic yarns so as to couple adjacent ones of the juxtaposing rows of loops together, whereby a flexible touch-fastening anti-skidding material is formed. 
     
     
         2 . The touch-fastening anti-skidding material according to  claim 1 , wherein the synthetic filaments are monofilaments selected from the group of synthetic materials consisting of nylon plastics, polyesters, polypropylene, and polyethylene. 
     
     
         3 . The touch-fastening anti-skidding material according to  claim 1 , wherein the pliable yarns are selected from the group consisting of processed DTY, polyester cotton, or cotton yarn. 
     
     
         4 . The touch-fastening anti-skidding material according to  claim 1 , wherein the pliable yarns are set to individually and transversely extend to the adjacent strand of the synthetic yarns in such a length that gaps are formed in the foundation layer to define hollow openings 
     
     
         5 . The touch-fastening anti-skidding material according to  claim 4 , wherein the hollow openings are of a shape selected from the group consisting of circle, honeycomb, and quadrangle. 
     
     
         6 . The touch-fastening anti-skidding material according to  claim 1 , wherein the free ends of the outward-extending legs are fused to form rounded ends. 
     
     
         7 . The touch-fastening anti-skidding material according to  claim 1 , wherein the free ends of the outward-extending legs are subjected to heating and compressed to form hooks.
