1.Description of SMS composite nonwoven fabric
Meltblown nonwoven fabric have the advantages of good uniformity, high filtration efficiency or strong barrier ability. However, due to the low strength of meltblown fibers and insufficient bonding strength between fibers, it has poor mechanical properties, small extension and no wear resistance. It is generally difficult to use independently before treatment.
Spunbonded nonwoven fabric have high strength and good wear resistance, but their uniformity and filtration accuracy are lower than those of meltblown nonwoven fabric. If the two advantages can be combined to achieve the effect of complementary advantages, the products can not only have good filtration and barrier effects, but also have good air permeability.
SMS Composite Nonwoven Fabric use composite technology to stack melt blown nonwoven fabric and spunbond nonwoven fabric to form a new nonwoven fabric with "sandwich" structure. SMS refers to a composite product with "three-layer" structure composed of two kinds of fiber networks. It is a general term of this kind of products. The actual number of layers of the product can be more than three, such as four-layer SMMS structure, five-layer SMMMS structure, six-layer SSMMMS structure, etc.
2.Advantages of SMS Composite Nonwoven Fabric
Because SMS composite products combine the advantages of spunbond nonwoven fabric and melt blown nonwoven fabric, they have the properties of high strength, good wear resistance, high filtration efficiency or strong barrier ability. They have been widely used in the fields of medical, health, health care and protective products. The products treated with anti-static, water repellent, alcohol repellent and blood repellent functions are the preferred materials for high-end medical protective articles.
