PP spunbond non-woven fabric is one of the many types of non-woven fabrics. It is made of polypropylene (PP material) as raw material, which is polymerized into a mesh through high-temperature drawing, and then bonded into cloth by hot rolling. A kind of non-woven fabric.
PP spunbond non-woven fabrics are widely used in various fields such as medical and sanitary materials due to their simple production process, large output, and non-toxic and harmless to human body.
PP spunbond non-woven fabrics Among the many manufacturing methods of non-woven fabrics, due to the obvious advantages in product performance and production efficiency made by the spunbond method, it has gained worldwide attention in the past 20 years. Rapid development.
About 40% to 50% of non-woven fabric production currently uses melt spinning methods (including spunbonding methods, melt-blown methods and composite methods of the two).
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. During the polymer spinning process, continuous filaments are formed into a web after spinning and then directly bonded. The manufacturing method of non-woven fabrics is very simple and fast. Compared with dry non-woven fabric processing technology, it eliminates a series of tedious intermediate processes such as fiber curling, cutting, packaging, transportation, mixing, and carding. This kind of The most significant effect of continuous and large-scale production is that the cost of spunbond products is reduced, the quality is stable, and the market competitiveness is strong. It can enter the textile, paper and film markets in various uses of disposable and durability. middle.
The pp spunbond non-woven fabrics supplied have high strength, small difference in vertical and horizontal strength, aging resistance, melting point of 164~170℃, and the products can be sterilized at temperatures above 100℃.
It has the characteristics of no deformation at 150℃ without being affected by external force.
