Spunbond nonwoven fabric, main material is polyester and polypropylene, high strength, high temperature resistance.

Spunbond nonwoven fabric: extruded the polymer, stretch, form a continuous filament, the filaments are laid into the net, the fiber is then bonded, thermally bonded, chemically bonded or mechanically reinforced, Turn into a non-woven fabric.

The main purpose:

The main material of the spunbond nonwoven fabric is polyester and polypropylene.

The main products of the  spunbond nonwoven fabric have polypropylene, polyester (long fiber, short fiber) non-woven fabric, our most common application is the non-woven bag, non-woven packaging, etc .; for spunbond nonwoven fabrics It is easier to identify, and the general bidirectional fastness is generally, and the general spunning nonwoven fabric is rhombic.

The apparatus can also be made of flowers packaging, box cloth, etc.

Technical type

The world's spunbonded non-woven technology mainly has German Lefen's Lekfel Technology, Italy STP technology, Japan's Kobe Steel Technology, etc. Current conditions, especially Leffen technology has become the world's mainstream technology. It has been developed to the fourth generation technology. It is characterized by draging a negative pressure ultra-high-speed airflow, and the fibers can be stretched to 1 denier. There have been many companies in China to make imitation. Because of many of their core technologies, there is no solve or master, domestic equipment manufacturing enterprises must reach the Leffen technology level still stay.

Characteristic

High temperature resistance, low temperature resistance (polypropylene can be used in a 150 ° C environment, polyester can be used for a long time in 260 ° C), aging, anti-ultraviolet, high stability and gas resistance, corrosion resistance , Sound, anti-mite, non-toxic.
