Core material of medical mask and N95 mask - melt blown cloth
Before 2020, most Chinese people are not familiar with the word melt blown cloth. Because of the new coronavirus, because of the large demand for masks, the word "melt blown cloth" came to the surface.
The melt blown cloth is the core material of the mask. The main material of the melt blown cloth is polypropylene. The diameter of the fiber can reach 1-5 microns. There are many voids, fluffy structure and good anti wrinkle ability. The superfine fiber with unique capillary structure increases the number and surface area of fibers per unit area, so that the melt blown cloth has good filtration, shielding, heat insulation and oil absorption. It can be used in the fields of air, liquid filter material, isolation material, absorption material, mask material, heat preservation material, oil absorption material and wiping cloth.
The melt blown cloth is mainly used in the following products, which are raw materials for production of these products:
Meltblown cloth is a kind of medical and health cloth: surgical clothes, protective clothing, disinfectant cloth, masks, diapers, women's sanitary napkins, etc;
Meltblown cloth is used for home decoration: wall cloth, tablecloth, bedspread, bedspread, etc;
Melt blown cloth is clothing cloth: lining, adhesive lining, flocs, set cotton, various synthetic leather bottom cloth, etc;
Melt blown cloth is industrial cloth: filter material, insulating material, cement packing bag, geotextile, wrapping cloth, etc;
Meltblown cloth is agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, heat preservation curtain, etc;
Meltblown cloth is used in space cotton, heat preservation and sound insulation materials, linoleum, smoke filter, tea bag, etc.
The melt blown cloth filter material is made up of polypropylene microfibres, which are randomly distributed and adhered together. The appearance of the material is white, flat and soft. The fineness of the material fiber is 0.5-1.0 μ M. the random distribution of the fiber provides more opportunities for thermal bonding between the fibers. Therefore, the melt blown gas filter material has a larger specific surface area and a higher porosity (≥ 75%). After high pressure electret filtration efficiency, the product has the characteristics of low resistance, high efficiency and high dust capacity.
The medical mask and N95 mask are composed of spunbond layer, melt blown layer and spunbond layer, among which the spunbond layer and melt blown layer are made of polypropylene PP material.
