Method or hot-air bonding method to form a non-woven fabric. Its output has High quality Airlaid Paper manufacturers accounted for 60% to 70% of the world's total output of nonwovens, and its application range is becoming wider and wider. The filament web is subjected to needle punching, spunlacing, chemical bonding, and hot rolling bonding.Spunbond non-woven fabric is based on the principle of chemical fiber spinning. In general, spunbond non-woven fabrics have a high comprehensive strength level, a smooth surface, low lintability, soft hand feel, fold and abrasion resistance, good shading and air permeability, good water absorption and lipophilicity, and heat resistance, acid resistance, and alkali resistance.

It is precisely because of the simple production process, short process flow, low product cost, unique structure and superior technical performance of spunbonded non-woven fabrics that it is widely used in the automotive industry, and its usage by area is far greater than that of other non-woven fabrics. During the process of polymer spinning, continuous filaments are laid into a net. The spunbond production technology can adapt to different types of polymers, the process flow is short, flexible and diverse, the technology is mature, the technology content is high, the degree of automation is high, and the spinning speed has doubled, the single fiber strength is greatly improved, and the fiber is more and more The finer the web, the faster the web formation speed and the better the web uniformity. Spunbond non-woven fabrics can be used not only as various interior decoration materials for automobiles, but also as sealing and waterproof materials for automobiles, as well as reinforcing skeleton materials for automobiles, as well as various packaging protection materials for automobiles, and it is also an ideal automobile Industrial filter materials..

Because spunbond non-woven fabric is directly formed by laying continuous filaments into a net, it has high fiber utilization factor, large coverage per unit area and good covering performance, so it can be processed into a low areal density non-woven fabric, which is other Unmatched by various non-woven fabrics. Weaving cloth. It is mildew and mothproof, good dimensional stability, easy to process, and easy to recycle. The spunbond nonwoven fabric is composed of continuous filaments, so it has good tensile strength; the filament density of the nonwoven fabric can be large or small, and the range of changes is wide; the web can be reinforced by various methods , So as to endow products with good application performance and enhance competitiveness
