What we know about spunbond nonwoven fabric?

Spunbond Nonwoven fabric, as a traditional and mature process belonging to nonwoven fabric, still maintains a core position through continuous innovation and technological iteration.

Spunbond nonwoven fabric is mainly formed through four steps: melt extrusion, drawing, web laying and hot rolling.

First, polypropylene or polyester (PET) polymers are melted at high temperatures.   Then, the melt is stretched into continuous filaments by high-pressure gas flow.   The fibers randomly fall to form a uniform fiber web.   Finally, the intersections of the fibers are pressed together by hot-rolling rollers.

Application scope

In the field of medical protection, surgical gowns/isolation suits are used. In the field of filtration, melt-blown layers are combined to achieve filtration efficiency. Other applications include the coating layers of hygiene products and furniture linings.
