Non-woven needle of fabric

Abstract

The invention provides a non-woven needle of fabric. The non-woven needle comprises a needle rod segment, a work segment and a needle point segment. The work segment and the needle point segment longitudinally extend in the first direction in sequence. The work segment is a triangular spiral body and is provided with a plurality of hook tooth sets, each hook tooth set comprises three hook teeth located on the same horizontal plane, and the hook teeth in the hook tooth sets are located on the edges of the work segment and are gradually enlarged in the second direction opposite to the first direction. The hook tooth sets gradually enlarged in equal proportion are arranged on the spiral edges of the work segment of the non-woven needle of the fabric, so that the probability that the hook teeth hook fabric fibers is reduced, initial puncture resistance of the non-woven needle is reduced, and therefore work efficiency is improved, and the phenomenon of needle breakage is reduced.

Description

technical field [0001] The invention relates to an accessory of a textile machine, in particular to a cloth non-woven needle. Background technique [0002] As we all know, cloth non-woven needles are special needles for dense cloth fibers. Many fabric non-woven needles form a dense needle array, piercing up and down on the fabric at high speed, so that the fabric fibers are intertwined, and the fluff on the warp and weft threads is squeezed and pushed into the back of the fabric. [0003] The cloth non-woven needle in the prior art includes: a needle bar and a working section arranged at the end of the needle bar. The end of the working section is provided with a needle point, and several hook teeth are arranged on the surface of the working section. The cloth non-woven needle pierces the cloth vertically, making the cloth fibers in the cloth intertwined with each other, and squeezes the fluff on the warp and weft threads and pushes them into the back of the cloth.

AI Technical Summary

Problems solved by technology

Straight-shaped fabric non-woven needles, because multiple hook teeth are arranged in a straight line, during the puncture process, when the first hook teeth randomly hook the fabric fibers, the probability of the subsequent hook teeth hooking the fabric fibers will be significantly reduced. At the same time, the initial resistance when the non-woven needle punctures the fabric is relatively large, and the needle is prone to breakage, resulting in low production efficiency

Although the spiral non-woven fabric needle increases the probability of the hook teeth hooking the fabric fiber, the initial resistance of the puncture is also relatively large, and the needle is prone to breakage
