Spunbonded nonwoven fabrics utilize the principle of chemical fiber spinning. Continuous filaments are laid into a web during the process of polymer spinning. The filament webs are subjected to needle punching, hydroentanglement, chemical bonding, and hot-roll bonding. The nonwoven fabric is formed by reinforcement by hot air or air bonding.

Spunbond production technology can adapt to different types of polymers, the process is short, flexible and diverse, mature technology, high technology content, high degree of automation, and spinning speed multiplied, single fiber strength is greatly increased, fiber The finer the speed is, the faster the network becomes and the better the uniformity of the network.

Its output has accounted for 60% to 70% of the total production of nonwoven fabrics in the world, and its application range is also growing. Spunbonded nonwoven fabrics are composed of continuous filaments, so they have good tensile strength; the density of the filaments that make up the nonwoven fabric can be varied, or can vary widely; the web can be reinforced by various methods. This gives the product good application performance and enhances its competitiveness. Since the

spunbonded nonwoven fabric is laid directly into a cloth after being laid into a net by a continuous filament, the fiber has a high coefficient of utilization, a large coverage per unit area, and a good covering property, so that it can be processed into a nonwoven fabric with a low surface density.

This is unmatched by other kinds of non-woven fabrics. In general, spunbonded nonwovens have a high level of comprehensive strength, a smooth surface with low lint, a soft hand, a good folding and abrasion resistance, a good light-blocking and air-permeability, good water-absorption and lipophilicity, and heat, acid, and alkali resistance. Anti-mold and mothproof, good dimensional stability, easy processing, easy recycling.

    Due to its simple production process, short process flow, low product cost, unique structure, and superior technical performance, spunbonded nonwovens are widely used in the automotive industry, and their usage is much larger than other non-wovens by area. Weaving cloth. Spunbond nonwoven fabrics can not only be used as a variety of automotive interior decoration materials, but also can be used as a car's seal waterproof material, can also be used as a car's reinforced skeleton material, but also can be used as a variety of car packaging protective materials, but also the ideal car Industrial filter material.
