Melt Blow non-woven fabric is an important raw material for the production of face masks, commonly known as the "heart" of the masks. It is a conventional fabrication method of micro- and nanofibers where a polymer melt is extruded through small nozzles surrounded by high speed blowing gas. It has good filtering, shielding, heat insulation and oil absorption properties. It can filter out viruses attached to body fluids. It mainly plays an indispensable filtering role in KN95 face masks.
Hot air cotton non-woven fabric is a kind of filling material in KN95 face masks. In order to balance the effect of warmth and protection, some manufacturers use hot air cotton non-woven fabric with high bulkiness, good elasticity, soft feel, strong warmth and good air permeability. It is sandwiched between the KN95 folding masks, which mainly plays the role of heat insulation, moisture and moisture resistance, and improves the wearer's comfort.
As opposed to traditional materials, such as cotton, linen, wool, and silk; non-woven fabrics do not necessitate weaving or knitting. They are broadly defined as sheet or web structures bonded together by entangling fiber or filaments mechanically, thermally, or chemically.
