In the production process of two-component non-woven thermal composite filter media, two different thermoplastic polymer slices are micro-emulsified through the hopper to the screw extruder. Under the action of high temperature and shear extrusion It is softened and melted to form a polymer, which is filtered through a melt filter to remove impurities. It is quantitatively fed into the multi-mode component under the action of a metering pump, and is extruded by a spinneret according to a certain proportion and arrangement.
Afterwards, it is refined and cooled by the drafting wind to form a two-component filament with a certain fineness and strength.
Finally, the bicomponent filaments are split, laid, and reinforced to form a nonwoven fabric.
It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
