What is the difference between medical PP, SMP, SM, SSPP and other materials? S stands for spunbond, spunbond non-woven fabric, M is meltblown non-woven fabric, and PP stands for polypropylene.

In the non-woven fabric process, there is a sandwich material called SMS, which has spunbond, spunbond and spunbond structures. This material has both good strength of spunbond fabric and good barrier properties of melt spunbond fabric, and is often used in medical products.

What is the difference between medical PP, SMP, SM, SSPP and other materials

SMS non-woven fabric is a combination of spunbond and melt-blown processes and production. The spun-bonded non-woven fabric has high strength, poor vertical and horizontal strength, poor performance, and melt-blown non-woven fabrics have high shielding properties. , 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 penetration into the blood.

SMS non-woven products can effectively prevent cross-infection between doctors and patients and protect the health of medical staff. In terms of price and isolation performance, SMS has many advantages over spunlace medical materials. In recent years, more modular composite material technologies have been developed, such as SMMS, SSMMS, etc., to form multilayer composite materials, thereby improving product quality while increasing output.

For spunbond/meltblown non-woven fabric composites, the surface layer (spunbond layer) determines the hand feel, and the inner layer (meltblown layer) improves shielding and filterability, thereby improving spunbond/meltblown properties. The comfort, softness and high barrier properties of blow-molded composite nonwoven materials are at the core, which further enhances the core competitiveness of my country's medical nonwoven fabric production industry.
