fabric non-woven needle

Abstract

The invention provides a nonwoven needle which comprises a shaft segment, an operating segment and a tip segment. The operating segment and the tip segment extend out sequentially lengthwise along a first direction. The operating segment is in a shape of a triangular spiral and is provided with a plurality of hooked tooth sets. Each hooked tooth set includes three hooked teeth on a same horizontal plane, and the hooked teeth in the hooked tooth set are located at edges of the operating segment and gradually enlarge in a second direction opposite to the first direction. The hooked tooth sets which gradually enlarge in equal proportion are arranged at spiral edges of the operating segment of the nonwoven needle, the probability that the hooked teeth hook to fabric fiber is increased, initial penetrating resistance of the needle is reduced, operating efficiency is improved, and 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
