The important reason for the rapid development of the spunbond method is that it uses synthetic polymers as raw materials. The method uses the principle of fiber spinning, which is made of continuous filament during the process of polymer spinning. The method is very simple and fast. A series of tedious intermediate processes, such as curling, cutting, packing, transporting, mixing, and combing. The most significant effect of this continuous and mass production is to reduce the cost of the spunbonded products, the quality of the products, the strong market competitiveness, and to the textiles, paper and film in various uses that are used for the sake of abandoning and durability. In the market area. Secondly, because of the large amount of polypropylene used in spunbonded nonwoven fabric as the main raw material, its advantages in price, process and production cost have greatly promoted the continuous development of the spunbonded non-woven fabric industry. In addition, spunbonded nonwoven fabric has excellent mechanical properties, and its tensile strength, elongation at break and tear strength are better than dry, wet, and meltblown non-woven fabrics, especially in recent years, the rapid development of spunbond in production line scale, technology and equipment and product market development, greatly expanding spunbonded non-woven fabric. The field of application.
