In recent years, with the rapid development of my country’s economic development and the improvement of productivity levels, many new products and new technologies have been well applied. Imported PP polypropylene filament non-woven fabrics are among them. Specifically, Let’s find out.
Imported PP polypropylene filament non-woven fabric is made by melting polymer particles or powder, then entering the extruder and spinning into continuous filament bundles through one or a series of spinnerets.
The filaments are then arranged irregularly by rotating spinnerets or controlling air flow, changing the speed of the conveyor belt, passing current, etc., and then laying them on the conveyor belt to form a fiber network.
The fiber web is bonded by hot pressing or adhesive bonding when the filaments are not completely solidified, or mechanically reinforced with needle punching to form a continuous and uniform geotextile.
Can be used in various projects such as reinforcement, separation, filtration and drainage.
Imported PP polypropylene filament non-woven fabric refers to extruding and stretching the polymer to form continuous filaments, then laying the filaments into a web, and then the fiber web is bonded by itself, thermally bonded, and chemically bonded Or mechanical reinforcement method to turn the fiber web into non-woven fabric.
The main materials of imported spunbond non-woven fabrics are polyester and polypropylene.
The main products are polypropylene, polyester (long fiber, short fiber) non-woven fabrics.
