Do you know the difference between PP non woven fabric and SMS non woven fabric?

May , 27 2021

Non woven fabric is a general term, because PET can also be used as non woven fabric, but PP non woven fabric limits the types of plastics. In principle, there is no difference between them. SMS is added on the basis of two spunbond production lines, a meltblown M production line. PP non woven fabrics are spunbond non woven fabrics, and PP refers to the raw materials for the production of non woven fabrics. Polypropylene, the product name in China is polypropylene, so sometimes you see polypropylene non woven fabrics, but they are all the same. The spunbond non woven fabric refers to the non woven fabric produced by S or SS. The production process of spunbond is different from the production process of meltblown M, and the forming is also different. S is spinning forming, and meltblowning is spray forming. SMS is added on the basis of two spunbond production lines, a meltblown M production line. The materials used are also different, and the process temperature is different. It is not difficult to see the difference between SMS and PP.

PP non woven fabric and SMMS non woven fabric information:

SMS non woven fabric (English: Spunbond + Meltblown + Spunbond Nonwovens) is a composite non woven fabric, which is a composite product of spunbond and meltblown. It has the advantages of high strength, good filtering performance, no adhesive, and non-toxic. At present, it is mainly used in medical and health labor protection products such as surgical gowns, surgical caps, protective clothing, hand washing clothes, handbags, etc. The material component is fiber.

The full name of pp is polypropylene, and the Chinese name is polypropylene. Nw is the abbreviation of nonwoven. It is a non woven fabric formed by airflow or mechanical formation of fibers, and then spunlacing, needle punching, or hot rolling reinforcement, and finally after finishing. ppnw means non woven fabric made of pp fiber. Due to the nature of pp, the final performance of the cloth is high, but the hydrophilic performance is poor. Usually the process flow of ppnw is spinning into a net and hot rolling reinforcement. Generally, ppnw has a wide range of uses, such as packaging bags, surgical protective clothing, industrial cloths, etc.
