Spunbond non woven bag: After the polymer is extruded and stretched to form continuous filaments, the filaments are spread into a net shape, and then the fiber net is self-bonded, thermally bonded, and chemically bonded. A combination or mechanical reinforcement method of making a fiber web into a non-woven fabric.
