What is the difference between hydrophilic PP, SMP, SM, SSPP in medical non woven fabrics?
S stands for spunbond, spunbond nonwoven fabric; M is a melt-blown non woven fabric. PP stands for polypropylene In the non woven fabric process, there is a sandwich material called SMS, which is a spunbond, spunbond and spunbond structure. This material has both good spunbond strength and good barrier properties of melt spunbond, and is often used in medical supplies. SMS non woven fabric is a combination of two processes and production of spun-bonded and melt-blown. The spun-bonded non woven fabric has high strength, poor vertical and horizontal strength, poor performance and melt-blown non woven fabric with high shielding The waterproof performance is concentrated on one material, which has 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. SMS non woven products can effectively prevent cross infection...
