Talk about the difference between pp non-woven fabric and sms non-woven fabric

<p>Pp stands for polypropylene. Nw is the abbreviation of non-woven, that is, non-woven fabrics. It is a non-woven fabric made by weaving fibers into a net shape by air flow or machine, and then reinforced by shot peening, needle punching or hot rolling, and finally finished.</p><p>&nbsp;</p><p>PPNW stands for non-woven fabric made of PP fibers. Due to the nature of pp itself, the final performance of the cloth is high strength, but poor hydrophilicity. The PPNW process is typically spun into mesh, hot-rolled rebar. Generally, PPNW is widely used in packaging bags, surgical protective clothing, industrial cloth, etc.</p><p><br></p><p><a href="https://www.synwinchina.com/sms-non-woven-fabric" rel="noopener noreferrer" target="_blank"><strong>SMS nonwovens</strong></a> (Spunbond+meltblast+Spunbond nonwovens) is a composite nonwoven, spunbond and meltblown composite product, which has the advantages of high strength, good filtration performance, no adhesive, and non-toxicity. At present, it is mainly used in medical and health labor protection supplies such as surgical gowns, surgical caps, protective clothing, hand washing clothes, and handbags.</p><p>&nbsp;</p><p>S table spunbond, Chinese translation is spunbond non-woven fabric; M stands for melt-blown, meaning melt-blown non-woven fabric. In the non-woven process, there is a sandwich structure material called SMS, which is a spunbond-meltblown-spunbond structure. This material combines the characteristics of good strength of spunbond cloth and good barrier properties of meltblown cloth, and is often used in medical medical materials. Some of the abbreviations you mentioned, we don't use them very often.</p><p>&nbsp;</p><p>SMS non-woven fabric is composed of two processes and production of spunbond and meltblown. , The waterproof performance is concentrated on one material, forming the advantages of strong waterproof performance, good air permeability and effective isolation performance, which can effectively cut off the penetration of bacteria and penetrate into the blood.</p><p><br></p><p>SMS non-woven products can effectively prevent cross infection between doctors and patients, and protect the health of medical staff. SMS offers many advantages over spunlace medical materials in terms of price and barrier properties. In recent years, more modular composite materials technologies, such as SMMS, SSMMS, etc., have been developed to form multi-layer composites, thereby improving product quality while increasing yield.</p><p><br></p><p>For spunbond/meltblown nonwoven composites, the surface layer (spunbond layer) determines the hand, and the inner layer (meltblown layer) improves barrier properties, filterability, and thus improves spunbond/meltblown properties. The comfort, softness and high barrier properties of blow-molded composite non-woven materials are the core, which further improves the core competitiveness of my country's medical non-woven fabric production industry.</p><p><br></p><p>Synwin is a <a href="https://www.synwinchina.com/" rel="noopener noreferrer" target="_blank"><strong>non woven manufacturer</strong></a> and non woven material cloth factory for agriculture and medical non woven fabric.
