PP spunbond nonwoven technology has always been to improve the ability of the production line and solve the problems of uniformity, covering, rough hand feel, etc., to improve the strength, softness, uniformity and comfort of spunbond nonwovens. hygroscopicity and other properties.
The important reason for the rapid development of the spunbond method is that it uses synthetic polymers as raw materials. This method uses the principle of chemical fiber spinning. In the process of polymer spinning, continuous filaments are directly bonded after spinning. Non-woven fabrics, the manufacturing method is very simple and fast. Compared with dry non-woven fabric processing technology, it saves a series of tedious intermediate processes such as fiber curling, cutting, packaging, transportation, mixing and carding. The most significant effect of mass production is that spunbond products can be reduced in cost, stable in quality, and highly competitive in the market. They can enter the market fields of textiles, paper and films in various applications of disposable and durability. Secondly, since spunbond nonwovens use a lot of polypropylene as the main raw material, it has many advantages in terms of price, processing process, production cost, etc., which also greatly promotes the sustainable development of the spunbond nonwoven industry. In addition, PP spunbond nonwoven products have excellent mechanical properties, and their tensile strength, elongation at break, tear strength and other indicators are better than those of dry, wet and meltblown nonwovens, especially in recent years, spunbond The rapid development in production line scale, technology and equipment and product market development has greatly expanded the application field of PP spunbond non-woven fabrics.
