China Meltblown Fabric for Korean 40g Kf94 Mask

Melt blown fabric (to meet the requirements of various width and weight), the product quality meets and passes the textile industry standard FZ / T 64078-2019 of the people's Republic of China

The core material of the mask is the fusible cloth
It mainly uses PP PP melt blown special material as the main raw material, which is developed and directly supplied by the polymer Department of Dajin new materials. The diameter of the fiber can reach 1 to 5 microns. The superfine fiber with unique capillary structure increases the number and surface area of fibers per unit area, so that the meltblown cloth has good filtration, shielding, thermal insulation and oil absorption.

Weight: 18g-500g
Width: generally 120cm, 160mm and 180cm
Production method of melt blown fabric:
Melt blown fabric is a kind of melt blown nonwovens made by high-speed hot air to draw the polymer melt from the spinneret hole of the die head to form superfine fibers, which are collected on the screen curtain or roller, and are self-adhesive to form melt blown nonwovens.
Production process of melt blown fabric:
1, melt preparation 2, filtration 3, metering 4, melt extrusion from spinneret hole 5, melt fine flow drafting and cooling 6, forming mesh
Product features: low resistance, high efficiency and high dust tolerance
The filter material of melt blown fabric is bonded together by polypropylene superfine fibers randomly, with white, smooth and soft appearance. The fiber fineness of the material is 1.0 mm of 0.5. The random distribution of fibers provides more opportunities for thermal bonding between fibers, so the melt blown gas filter material has larger specific surface area, higher porosity (≥ 75%), and better filtration efficiency after high pressure electret.
