Description

Water thorn microfiber composite nonwoven fabric

Technical Field

The utility model relates to the technical field of non-woven fabrics, in particular to a spun-laced microfiber composite non-woven fabric.

Background

In the technical field of industrial production of semiconductors, cosmetics and the like, the requirements on the production and processing environment are very high, and the degree of environmental cleanliness directly influences the yield and quality of the terminal product. The high-efficiency filter material matched with the ultra-clean production workshop is needed, so that the requirement of the production environment can be met when the external air is exchanged with the air in the workshop.

However, most of the filtering materials used in the prior art are chemical fiber materials such as glass fiber or polytetrafluoroethylene. The glass fiber has high rigidity and is easy to brittle fracture, so that the glass fiber is dispersed in the space in a production workshop, and on one hand, the reject ratio of a terminal product is increased; on the other hand, fine glass fibers are sucked into a human body and are difficult to metabolize, so that the health hidden trouble of production workers can be brought.

The superfine fiber has a larger specific surface area and proper pores, and can adsorb, capture and block solid particles in air, so that the superfine fiber becomes an excellent filtering material. At present, a large number of ultrafine fiber nonwoven fabrics are used in the field of air filtration, and are melt-blown nonwoven fabrics and electrostatic spinning materials. However, the existing filter uses short fibers to increase the filtering efficiency, and thus the receiving space can be increased. However, the use of the short fibers may cause the short fibers to fall off from the filter material to make the plant, which may affect the environment of the plant.

How to prepare a superfine fiber non-woven fabric as an air filtering material, short fibers are not used on both surfaces, so that the possibility of falling off of the short fibers is avoided.
