Definition editor:
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 bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the web It becomes a non-woven fabric.
Featuresedit:
Good high temperature resistance, good low temperature resistance (polypropylene can be used for a long time in an environment of 150 ℃, polyester can be used for a long time in an environment of 260 ℃), aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance , Sound insulation, mothproof, non-toxic.
Main purposeedit:
The main materials of spunbond non-woven fabrics are polyester and polypropylene.
The main products of spunbond non-woven fabrics are polypropylene and polyester (long fiber, short fiber) non-woven fabrics. Our most common and commonly used applications are non-woven bags, non-woven packaging, etc.; for spunbond non-woven fabrics It is easy to identify and generally has good two-way fastness. Generally, the nip point of spunbonded non-woven fabric is diamond-shaped.
At the application level, it can also be used for flower packaging cloth, luggage cloth, etc. The characteristics of wear resistance, firm hand feeling, etc. make it the best choice for making this type of product.
