AI Technical Summary

Problems solved by technology

However, the wet breaking strength is small, and the shrinkage deformation of the fabric made of pure viscose fiber is large
The strength of viscose fiber is lower than that of cotton fiber, it is not washable, its elongation at break is higher than that of cotton fiber, it has poor wear resistance, it is easy to deform under small load, it has poor dimensional stability, low stiffness and poor elasticity
[0013] Polyester fiber has the advantages of high strength, good recovery, and good heat setting, but the mass specific resistance of polyester fiber is large, and the electrostatic phenomenon is prominent, which makes it difficult to form a net in the process of carding pure polyester fiber.

Description

technical field [0001] The invention relates to the field of health-care spunlaced fabrics for medical textiles, in particular to a spunlaced nonwoven base fabric of isatidis antiviral fiber and a preparation method thereof. Background technique [0002] The principle of hydroentanglement to consolidate the fiber web is similar to the acupuncture method in the dry process. It relies on the ultra-fine high-pressure water flow (also known as water needle) sprayed by the hydraulic jet (water puncture head) to pierce the fiber web, making the short Fibers or filaments entangle to consolidate the web. The principle of hydroentanglement reinforcement is similar to that of acupuncture, but instead of needling needles, multiple fine water jets generated by high pressure are used to spray the fiber web, commonly known as "high-pressure water needles". After the water needle passes through the fiber net, it is entrusted to hold the rebound of the net curtain and penetrates the fiber ...
