Release time:
2017-12-14
SMS is an addition to two spunbond production lines, a melt blown M production line. PP non-woven fabric refers to spunbonded non-woven fabric, and PP refers to the raw material for the production of non-woven fabric. Polypropylene, the product name in China is polypropylene, so sometimes we see polypropylene non-woven fabric, which is actually the same. Spunbonded non-woven fabric refers to the non-woven fabric produced by S or SS. The production process of spunbond is different from that of melt blown M, and the forming process is also different. S is spinning forming, while melt blown is spray forming. The materials used are also different, and the process temperature varies. This way, it's not difficult to see the difference between SMS and PP.
PP non-woven fabric and SMMS non-woven fabric information:
SMS non-woven fabric belongs to composite non-woven fabric, which is a composite product of spunbonded and melt blown. It has advantages such as high strength, good filtration performance, no adhesive, and non-toxic. Currently, it is mainly used for medical and health labor protection products such as surgical gowns, surgical hats, protective clothing, hand washing clothes, handbags, etc. The material composition is fiber.
The full name of PP is polypropylene, and its Chinese name is polypropylene. Nw is the abbreviation for nonwoven, which is either non-woven or non-woven fabric. It is a non-woven fabric formed by weaving fibers into a web through airflow or mechanical means, followed by water pricking, needle punching, or hot rolling reinforcement, and finally finishing. PPNW means non-woven fabric made of PP fibers. Due to the inherent properties of PP, the fabric ultimately exhibits high strength but poor hydrophilicity. The usual process for PPNW is spinning into a web and hot rolling reinforcement. Generally, PPNW has a wide range of uses, such as packaging bags, surgical protective clothing, industrial fabrics, etc.
