Problems solved by technology

In the acupuncture process, the requirements for the needles are relatively strict. In the face of nonwoven fabrics with different customer specifications and uses, different needle boards need to be replaced to process and produce the products, which increases the cost of production accessories for the enterprise.
[0012]②Stitch-bonding method: For the stitch-bonding method, there are certain requirements for the fiber arrangement of the fed web, and the stitch-bonding mechanical process and equipment structure are relatively complicated. And the rate of broken needles is high, and the maintenance cost is high
[0013]③Spunlace method: For the spunlace method, there is a certain requirement for water energy. According to the technical specifications of different commercial products, the water jet required in the process The hole diameter and arrangement need to be adjusted accordingly, which greatly increases the mold cost in the product production process
[0018] In summary, whether it is mechanical fixing based on physical mechanism or chemical bonding and thermal bonding based on chemical mechanism fixing, the fixing mechanism is relatively Single, their respective advantages and disadvantages are relatively prominent. While solving these shortcomings, it needs to consume a lot of production costs for production enterprises, which has a great impact on large-scale, high-efficiency, and high-performance production

Abstract

The invention discloses a net fixing method for a non-woven material and an electric-piercing net fixing device. The method comprises the following steps of melting the non-woven material under a high-voltage discharge tip. According to the net fixing method, the production efficiency is effectively improved, and the production cost is reduced; the mechanical property of the non-woven material is improved; and the breaking strength (the improvement rate is 10%-30%) and the tearing strength (the improvement rate is 10%-30%) of the non-woven material are effectively improved. The net fixing device is simple in structure, low in cost and short in processing flow, post-treatment on materials and processes is not needed, and the production process cost is reduced by 5%-20%.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric manufacturing, in particular to a method for fixing a nonwoven material and an electric stabbing device. Background technique [0002] Non-woven materials refer to sheets, webs or batts made of oriented or randomly arranged fibers combined with each other through friction, cohesion or bonding or a combination of these methods; non-woven technology is textile, paper, plastic, high It is a new discipline and new technology intersecting with other industrial edge sciences such as molecular materials and chemical industry. In recent years, the nonwovens industry has sprung up with its own vigorous vitality and developed vigorously. It has become the third field after weaving and knitting, and is known as the sunrise industry. [0003] The preparation process of nonwoven materials mainly includes web forming, fiber web reinforcement (fixed net), finishing and forming; among them, fiber web rei...
