The characteristics of irritation, rich color, low price, recycling and other characteristics. For example, polypropylene (PP material) granules are used as raw materials, and it is produced by high temperature melt, spraying, paving, and hot pressure rolls. It is called cloth due to the appearance and certain performance.
For those who are new to the nonwoven fabric industry, non woven fabrics of various materials and various processes make people easily confuse, especially for business or sales, the difference between the non -woven fabric process is not distinguished. It is not uncommon to find that bad orders are bad due to craftsmanship, so what does S, S, SMS, SMMS often say in nonwoven fabrics mean?
Non woven fabrics can be divided into S, SS, SMS, SMMS
S: spinning non woven fabric = single -layer fiber mesh hot rolling;
SS: spinning non woven fabric+spinning non woven fabric = two layers of fiber nets;
SMS: Spinning non woven fabric+melting jet non woven fabric+spinning non woven fabric = three -layer fiber net hot rolling;
SMMS: Spinning non woven fabric+melting jet non -woven fabric+melting no woven fabric+spinning nonwoven fabric = four layers of fiber mesh.
Non -woven fabrics, also known as non woven fabrics are composed of targeted or random fibers. They are a new generation of environmentally friendly materials. They have moisture -proof, breathable, flexible, light light, non -combustion, easy to decompose, non -toxic and irritating, rich color, low price, low price The characteristics of recycling and then use. For example, polypropylene (PP material) granules are used as raw materials, and it is produced by high temperature melt, spraying, paving, and hot pressure rolls. It is called cloth due to the appearance and certain performance.
s: spunbond spinning M: Meltblow
So SMMS is the composite of spinning +2 melting spray+spinning
