の糸条間のスリップが著しく、粗剛で、しかも嵩高であ
るため取扱いが難しいなどの致命的な欠点があった。In the case of knitted fabrics made of polyvinyl chloride or polyvinylidene chloride fiber threads, when these are heat-sewn together, the fibers melt at the heat-sewn portions of the fiber threads and adhere to each other. There was a drawback that the strength of the joint portion was reduced. In addition, when producing knitted fabrics using resin-coated yarn, the yarn surface friction resistance is large, making the weaving and weaving process difficult and the manufacturing efficiency low.Furthermore, the thread intersections are raised L, making it difficult to use. I didn't like the appearance. In addition, both products had fatal drawbacks such as significant slippage between the yarns in the product, being coarse, rigid, and bulky, making them difficult to handle.
