At present, there are many production processes for the manufacture of non-woven fabrics, among which the spunbond method is one of them. High-efficiency and low-resistance spunbond non-woven fabric is a kind of non-woven fabric produced by the spunbond method.
The spunbonding method combines fiber spinning technology and nonwoven molding technology. It uses the principle of melt spinning. After the raw materials are melted and mixed by the extruder, they are extruded from the spinneret of the spinning head to form a melt. Body trickle.
Using high-speed quenching air to cool the extruded melt thin flow, and at the same time, the fiber is stretched by the drawing air flow during the cooling process, forming a continuous filament with higher strength and more stable performance.
High-efficiency low-resistance spunbond non-woven fabrics are made by extruding and stretching polymers to form continuous filaments. The filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically. Reinforcement method to turn the fiber web into non-woven fabric.
It has good high temperature resistance, good low temperature resistance (polypropylene can be used in an environment of 150℃ for a long time, polyester can be used in an environment of 260℃ for a long time), aging resistance, UV resistance, high elongation, stability and breathability Good, corrosion-resistant, sound-insulating, moth-proof and non-toxic.
High-efficiency and low-resistance spunbond non-woven fabrics for sale can be widely used in air filtration, packaging materials, medical tapes, cable wrapping, biofilms and other fields.
