What is the Characteristics of SMS spunbond meltblown nonwoven fabric
In the nonwoven fabric process, there is a sandwich material called SMS, which is spunbond, meltblwon and spunbond. This material has both good spunbond fabric strength and good barrier properties of meltblwn fabric, and is often used in medical supplies.
SMS non-woven fabric is composed of spunbonded and melt-blown processes and production. The spunbonded non-woven fabric has high strength, poor vertical and horizontal strength, poor performance and melt-blown non-woven fabric has high shielding property. The waterproof property is concentrated on one material, forming strong waterproof property, good permeability and effective isolation property, which can effectively cut off the penetration of bacteria and penetrate into the blood.
SMS non-woven products can effectively prevent cross-infection between doctors and patients, and protect the health of medical staff. Compared with spunlace medical materials, SMS has many advantages in terms of price and isolation performance. In recent years, more modular composite technologies have been developed, such as SMMS, SSMMS, etc., to form multi-layer composite materials, thus improving product quality while increasing production.
For spunbonded/meltblown nonwoven composites, the surface layer (spunbonded layer) determines the feel, and the inner layer (meltblown layer) improves the shielding and filtration, thus improving the spunbonded/meltblown properties. The comfort, softness and high barrier of blow-molded composite nonwovens have further improved the core competitiveness of China’s medical nonwovens production industry.
