What are the differences and advantages of SS spunbond non-woven fabrics?

  Spunbond non-woven fabric : After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally  bonded, chemically bonded or mechanically reinforced to make the web It becomes a non-woven fabric. SS non-woven fabric : It is made by hot rolling of two layers of fiber net, the finished product is non-toxic, tasteless, and has high-efficiency isolation. Through special treatment of  equipment and technology, it can achieve antistatic, anti-alcohol, anti-plasma, and water-repellent properties. . SS: Spunbond non-woven fabric + spunbond non-woven fabric = two-layer fiber web hot rolled Spunbond non-woven fabric , the main materials are polyester and polypropylene, with high strength and good high temperature resistance.

  Elastic non woven fabric   is a brand-new non woven product, which breaks the situation of air-impermeable, over-tight, and low-stretchability of elastic film materials. Elastic non-woven fabrics are widely used in some life care products. So, what are the characteristics and advantages of elastic non woven fabrics compared with ordinary non woven fabrics? Currently, there are various types of  elastic materials , using various production processes and having different characteristics. 1. Elastic spandex yarn High stretch recovery, the product is combined with the surface layer non-woven fabric to form a longitudinal stretch non-woven fabric, with mature technology and low cost. 2. Hot melt elastomer The elastomer spinneret is combined with the surface layer non-woven fabric to form a longitudinal elastic non-woven fabric. 3. Four-sided stretch non woven fabric/film Spunbond process production, elastic body spinneret spreading, forming and winding, the product is combin...
