Non-woven needle

Abstract

The invention provides a non-woven needle which comprises a needle bar section, a work section and a needle point section, wherein the work section and the needle point section sequentially extend along a first direction; the work section comprises a first local section, a second local section and a first reducing cone for connecting the first local section with the second local section; a plurality of first hook teeth are annularly distributed on the surface of the first local section; a plurality of second hook teeth are annularly distributed on the surface of the second local section; the diameter of the first local section is greater than that of the second local section; and the depths of the first hook teeth are greater than the depths of the second hook teeth. According to the non-woven needle disclosed by the invention, the work section of the non-woven needle is arranged into the first local section and the second local section of which the diameters are gradually reduced; and the first hook teeth and the second hook teeth are spirally and annularly arranged on the surfaces of the first local section and the second local section. Due to the adoption of the structure, the probability that fabric fibers are hooked by the hook teeth on the surface of the non-woven needle is remarkably improved, the initial resistance of needling is reduced and the production efficiency is increased.

Description

technical field [0001] The invention relates to an accessory of a textile machine, in particular to a non-woven needle. Background technique [0002] As we all know, non-woven needles are special needles for dense fabric fibers. Many 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 nonwoven needle in the prior art includes: a needle shaft and a working section arranged at the end of the needle shaft. 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 non-woven needle pierces the fabric vertically, making the fabric fibers in the fabric entangled with each other, and squeezing the fluff on the warp and weft threads and pushing them into the back of the fabric. [0004] The working se...

Problems solved by technology

For straight non-woven needles, since the multiple hook teeth are arranged in a straight line, when the first hook teeth randomly hook the fabric fibers during the puncture process, the probability of the subsequent hook teeth hooking the fabric fibers will be significantly reduced. 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 needle increases the probability of the hook teeth hooking the fabric fibers, the initial resistance of the puncture is also relatively large, and the needle is prone to breakage
