Meltblown non-woven fabrics use polypropylene as the main raw material, and use high-speed hot air flow to draft the thin stream of polymer melt extruded by the die spinneret, thereby forming microfibers and collecting them on the condensation curtain or drum, and at the same time bonding themselves to become meltblown nonwovens.

Medical three-antibody spunbond spray melt composite non-woven fabrics SMS, SMMS, SMMMS still rely on imports. After SARS, domestic SMS non-woven fabrics developed rapidly, and in 2006, a production capacity of more than 60,000 tons was formed, but due to technical and device reasons, the production line was not operating normally, the output was only more than 20,000 tons, and the operating rate was only 30%. By 2010, China's online composite SMS non-woven fabric production capacity reached 260,000 tons, with an output of 91,000 tons. Since thin and medium-thickness SMS non-woven fabrics are mainly used for medical and hygiene products, their original production capacity matches the production capacity of protective clothing, masks and other production capacity, and the current surge in demand for downstream protective products has also led to a shortage of SMS non-woven fabric supply.

Meltblown non-woven fabric is used for the filter layer of masks.

Spunlace non-woven fabric is to spray high-pressure fine water flow into one or more layers of fiber network, so that the fibers are intertwined with each other, so that the fiber mesh can be reinforced and has a certain strength, the resulting fabric is spunlace non-woven fabric.

Clean and high whiteness viscose staple fiber is mainly used in the production of spunlace non-woven fabrics, which can be used to produce masks, gauze, surgical covers, medical napkins, wet wipes, face masks, cotton pads, clothing interlinings and other products.

Spunlace non-woven fabrics are used for the outer and inner layers of masks.
