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.

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.
