Indispensable Hot Air Cotton For N95 Masks

Melt Blown Nonwoven and Hot Air Cotton are both raw materials of N95 masks, so what is the difference between them? The Hot Air Through Nonwoven Fabric, which is also called Filter Cotton, can only achieve the initial filter effect, so it cannot replace the melt blown Nonwoven Fabric. Since Hot Air Non Woven Fabric cannot replace melt blown nonwoven, what role does it play in KN95 masks? Is it an indispensable material?

The Hot Air Cotton Fabric is a kind of filling material in the KN95 mask, which takes into account the effect of warmth retention and protection. The middle of the folded mask mainly plays the role of thermal insulation, moisture - proof and moisture - proof, and improves the comfort of the wearer. Although hot air cotton fabric cannot replace Meltblown Nonwoven Fabric, both are N95 mask materials, and both are indispensable.

Hot air cotton ( non - glued cotton ) is a new type of thermal insulation material, which is a replacement product of spray - glued cotton and imitation silk cotton. Its fixation method is to mix a certain amount of low - melting fiber or two - component fiber in the raw material. After heat drying in the production process, the fibers are fused immediately, so the production speed of hot air cotton is fast, the output is high, and the cost is low.

Hot air cotton can be used in various fields according to the density. The general thickness is used for KN95 protective masks, baby diapers, adult incontinence pads, fabrics for women's hygiene products, napkins, bath towels, disposable tablecloths, etc. Thick products are used to make cold - proof clothes, quilts, baby sleeping bags, mattresses, sofa cushions, etc. High - density hot - melt adhesive products can be used to make filter materials, sound insulation materials, shock absorption materials, etc.
