Problems solved by technology

[0002] Non-woven fabrics refer to fabrics that are not woven, but are entangled with fibers by physical or chemical methods, or partially bonded together. It has the characteristics of high output and simple process, so the production of modern non-woven fabrics has developed rapidly. Especially for functional non-woven fabrics, functional particles are added to non-woven fabrics according to different needs, and various new functions are given to the finished fabrics, such as elastic non-woven fabrics, antibacterial non-woven fabrics, super absorbent non-woven fabrics, Flame-retardant non-woven fabrics, etc., there are generally three ways to add functional particles: melt blending method, coating method and the method of using particles to stick near the nozzle, the process is complicated and there is a lot of dust

preparation example Construction

[0008] The preparation method of the present invention is the following steps:

[0009] ①. According to the normal process, ordinary natural cotton staple fibers are combed into a web by airflow, and then the fiber web is folded and pre-wetted;

[0010] ②. Carry out spunlace reinforcement to the fiber net. During spunlace, add 20% of functional particles (to the weight of cotton fibers) into the spunlace water. The functional particles are nano-antibacterial agents, activated carbon, diatomaceous earth, zeolite and activated alumina, 8 % The dispersant to the weight of the functional particles is evenly mixed in the spunlace water, and it is brought into the interior of the fiber web by the positive and negative spunlace reinforcement of the spunlace. The number of spunlace heads is 7-12, and the commonly used water pressure is 90-200Bar, adjust the pH value of the water to 6.5-7.5, and at the same time save particles. Add a layer of fine cloth under the mesh curtain to filter...

Embodiment 1

[0014] Ingredients: cotton fiber short fiber, nano antibacterial agent, activated carbon, diatomaceous earth, zeolite and activated alumina total 20% (to the weight of cotton fiber);

[0015] Preparation:

[0016] ①. According to the normal process, ordinary natural cotton staple fibers are combed into a web by airflow, and then the fiber web is folded and pre-wetted;

[0017] ②. Carry out spunlace reinforcement to the fiber net. During spunlace, add 20% of functional particles (to the weight of cotton fibers) into the spunlace water. The functional particles are nano-antibacterial agents, activated carbon, diatomaceous earth, zeolite and activated alumina, 8 % The dispersant to the weight of the functional particles is evenly mixed in the spunlace water, and it is brought into the interior of the fiber web by the positive and negative spunlace reinforcement of the spunlace. The number of spunlace heads is 7-12, and the commonly used water pressure is 90-200Bar, adjust the pH...

Embodiment 2

[0020] Batching: polyester fiber, Fe3O4Nanomagnetic functional material and nanocrystalline composite rare earth permanent magnetic functional material total 18% (to polyester fiber weight), its implementation method is the same as embodiment one.

[0021] In summary, the functional non-woven fabric of the present invention uses short cotton fibers, nano-antibacterial agents, activated carbon, diatomaceous earth, etc. as raw materials, and has a simple process, does not require major modifications to existing equipment, and has less weaving dust. , suitable for multi-variety production, which improves the production value of the product.

Abstract

The invention provides a novel weaving concept of functional non-woven fabrics and a method thereof. Common natural staple fibers are combed into a net through air current or polymer fibers are melted and extruded into a net; the fiber net, after prewet out in a parallel laying or folding laying way, is in a spun-laced way consolidated and dried, then further consolidated by chemical adhesion or thermal adhesion. The functional particle of the fiber net can be added flexibly, and is suitable for multi-product production; the invention has simple technology, requires no dramatic alteration to the present equipment and can obviously improve weaving performance and improve weaving efficiency.

Description

technical field [0001] The invention relates to a weaving method of a non-woven fabric, especially a weaving method of a non-woven fabric containing functional microparticles. Background technique [0002] Non-woven fabrics refer to fabrics that are not woven, but are entangled with fibers by physical or chemical methods, or partially bonded together. It has the characteristics of high output and simple process, so the production of modern non-woven fabrics has developed rapidly. Especially for functional non-woven fabrics, functional particles are added to non-woven fabrics according to different needs, giving various new functions to the finished fabrics, such as elastic non-woven fabrics, antibacterial non-woven fabrics, super absorbent non-woven fabrics, Flame-retardant non-woven fabrics, etc., there are generally three ways to add functional particles: melt blending method, coating method and the method of using particles to stick near the nozzle, the process is complic...
