What is the spun-bonded non-woven fabric process? The main materials of spunbonded non-woven fabrics are polyester and polypropylene. The world's spun-bonded non-woven fabric technology is mainly the German Leifen Lecofer technology, Italy's STP technology, Japan's Kobe steel technology. At present, especially the Levin technology has become the mainstream technology in the world. At present, it has developed to the fourth generation technology. It is characterized by the use of negative pressure ultra-high speed air draft, and the fiber can be stretched to about 1 denier.

What is the spun-bonded non-woven fabric process? The spun-bonded non-woven fabric process is as follows:

Polypropylene: polymer (polypropylene + feedback) - large screw high temperature melt extrusion - filter - metering pump (quantitative transport) - spinning (spinning inlet up and down stretch suction) - cooling - air traction - mesh curtain into mesh - upper and lower press roller (pre-reinforcement) - rolling mill hot rolling (reinforcement) - winding - reverse cloth sashing - weighing packaging - finished products into storage

Polyester: Processed polyester slice -- large screw rod high temperature melt extrusion -- filter -- metering pump (quantitative transport) -- spinning (spinning inlet drawing up and down suction) -- cooling -- air traction -- mesh curtain into mesh -- upper and lower press roller (pre-reinforcement) -- rolling mill hot rolling (reinforcement) -- winding -- reverse cloth sashing -- weighing and packaging -- finished product storage
