Structure characteristics of spunbond non-woven fabrics and introduction to its process flow

Spunbond non-woven fabric: After the polymer has been extruded and stretched to form discontinuous filaments, the filaments are laid into a web, and the web is then self-bonded, thermally bonded, chemically bonded or sluggishly reinforced. , So that the fiber web becomes a non-woven fabric.　　 High strength, good high temperature resistance efficiency (can be used for a long time at 150℃), aging resistance, UV resistance, high stretch rate, strength and air permeability, corrosion resistance, sound insulation, mothproof, non-toxic. The secondary spunbond non-woven fabric is coated non-woven polyester (long fiber, staple fiber). The most common and most commonly used is the operation of non-woven bags, non-woven packaging, etc., and it is also very It is easy to identify, because the nip of the spunbond non-woven fabric is obituary.　　The level of use is also roughly done. Flower packaging cloth, luggage cloth, etc., are endowed with abrasion resistance, good knot feel, etc., making him the best choice for creating such products.
