According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.
Needle-punched cotton is a kind of non-woven fabric, including many non-woven fabrics.
The development of the melt-blown method began in the early 1950s.
Melt blown cloth looks nothing special, but the production process is very complicated.
During the production process, the heated high-pressure air is blown out at a very high speed from the stretching air duct.
Melt-blowing method is to spray the melt extruded by the screw with a high-speed and high-temperature airflow, so that the thin stream of the melt is stretched at a higher magnification to form ultra-fine short fibers.
The non-woven fiber formed by the process of dividing and laying the net has only a simple physical entanglement between the fiber filaments.
