Warp-knitted self-fastening hook face fabric and manufacturing method thereof

Abstract

The invention discloses a warp-knitted self-fastening hook face fabric and a manufacturing method thereof. The fabric comprises bottom cloth formed through a warp-knitted mesh fabric knitted through a Raschel warp knitting machine, and a terry layer which is located on the surface of the bottom cloth and which is formed by a plurality of arched terries. Each arched terry is broken to form two hooks arranged oppositely, and the top of each hook is an irregular projection. Preferably, the bottom cloth is made of a warp-knitted mesh fabric by knitting polypropylene monofilaments, and the projection of the top of each hook is in irregular triangular shapes. The weight of the unit area of the bottom cloth ranges from 40 to 45g / m2, and the length of each hook ranges from 1 to 2mm. The manufacturing method of the warp-knitted self-fastening hook face fabric includes a knitting step, a heat setting step and a fusing step. The warp-knitted self-fastening hook face fabric is soft and light and high in fastening and hooking strengths, and substance exchange and tissue growth of human tissues are promoted after the warp-knitted self-fastening hook face fabric is implanted in a human body.

Description

technical field [0001] The invention relates to a Velcro hook fabric and a manufacturing method thereof, belonging to the technical field of Velcro fabrics. Background technique [0002] Velcro fabrics are widely used in clothing, hats, bags, sports equipment and medical equipment. Velcro fabrics include hook fabrics and suede fabrics. The combination of hook fabrics and suede fabrics can play the role of zippers. Use It is very convenient and fast to get up. The existing Velcro and hook fabrics are usually produced by woven method, injection molding method, injection molding insert method and roll forming method, wherein the woven method is to first spin the raw material into silk, and then fix the silk on the embryo belt , The spinning process is generally: polymer-spinning-oiling-pre-grid-winding-POY silk, and the equipment used to fix the silk on the embryo belt is a high-speed shuttleless loom. The injection molding method is to inject polyamide into a hook surface ma...

Problems solved by technology

Since the hook surface base fabric of this structure is made of woven fabric interwoven with warp and weft yarns, the hook surface base fabric is relatively hard and closed without air mesh. In some application fields, such as for planting In the human body fabric, the base fabric is stiff and thick, and the characteristics of no air-permeable mesh cannot meet the application requirements; moreover, because the hook surface distribution of this structure presents a certain regularity, the bonding strength and hooking strength are low. It is not conducive to the multiple punctures of the hook surface and the rough surface
