Non-woven fabric equipment - Screw extruder

Non-woven Fabric Equipment - Screw Extruder The screw extruder is a widely used basic equipment in polymer processing and an important device in the production lines of spunbond and meltblown non-woven fabrics. The basic working principle of the screw extruder: Solid raw materials enter the feed section of the extruder from the feed inlet and are pushed forward as the screw rotates. During this process, the heat energy provided by the heating device, the shear heat generated by the rotation of the screw itself, and the changes in the volume of the screw groove continuously compress the raw materials, generating strong friction that leads to continuous heating. This causes the raw materials to transform from a solid state to a highly elastic state, and finally to a molten viscous state of polymer melt. Under the thrust of the screw, the material is extruded from the die head at a certain pressure. The screw extruder mainly consists of the screw and barrel, drive device, heating and cooling devices, and electrical control system.

Light weight: Polypropylene resin is used as the main raw material for production, with a specific gravity of only 0.9, only three-fifths of cotton, with fluffy and good hand feeling. 2. Soft: composed of fine fibers (2-3D) light point-like hot melt bonding molding. The finished product is moderately soft and comfortable. 3. Water repellency and breathability: Polypropylene chips do not absorb water, have zero moisture content, and the finished product has good water repellency. It is composed of 100% fiber, which is porous and has good air permeability. It is easy to keep the cloth surface dry and easy to wash. 4. Non-toxic and non-irritating: The product is produced with FDA-compliant food-grade raw materials, without other chemical components, with stable performance, non-toxic, no peculiar smell, and does not irritate the skin. 5. Antibacterial and anti-chemical agents: Polypropylene is a chemically passive substance, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and finished products do not affect the strength due to erosion. nonwoven fabric joint machine--make big width nonwoven fabric for agriculture cover 6. Antibacterial properties. The product is water-repellent, not moldy, and can isolate the erosion of bacteria and insects in the liquid, and is not moldy.
