What is spunbonded non-woven fabric process and process
What is spunbonded non-woven fabric? Spunbonded non-woven fabric process and process;
Spunbonded non-woven fabric refers to the method of laying the filament into a net after the polymer has been squeezed out and stretched to form a continuous filament, and the fiber net is then bonded, bonded, chemically bonded or mechanically reinforced by itself, make the fiber mesh into a non-woven fabric.
It is characterized by high strength and good high temperature resistance (Can be used in 150 ℃ environment for a long time)
, Aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, moisture resistance and non-toxicity.
The main products of spunbonded non-woven fabrics are polypropylene polyester (Long fiber, staple fiber)
The most common and commonly used applications are non-woven bags, non-woven packaging and so on, and they are also easy to identify, because the rolling point of spunbonded non-woven fabrics is diamond-shaped.
The application level can also make flower packaging cloth, luggage cloth and so on, wear-resistant, firm and feel good, making him the best choice for making such products.
Spunbonded non-woven fabric process polymer (Polypropylene, return)--Large screw stalk high temperature melting extrusion--Filter--Metering pump (Quantitative delivery)--Spinning (Spinning inlet up and down stretching suction)--Cooling--Airflow traction--Mesh--Up and down Roller (Pre-reinforcement)--Rolling Mill hot rolling (Reinforcement)--Winding--Split--Weighing package--
Finished products are put into storage and the technical types of spunbonded non-woven fabrics. The world's spunbonded non-woven fabrics mainly include lecofel technology from Germany, STP Technology from Italy, Kobe Steel technology from Japan, etc.
The current situation, especially Laifen technology, has become the mainstream technology in the world. At present, it has developed to the fourth generation technology.
It is characterized by negative pressure ultra-high speed airflow drafting, and the fiber can be stretched to about 1 but Neil.
Many domestic enterprises have already copied it. Since many cutting-edge problems in their core technologies have not been solved or mastered, it will take some time for domestic equipment manufacturing enterprises to reach Laifen's technical level.
