Spunbonded non-woven fabric refers to the polymer that has been extruded, stretched, and formed into a continuous filament, the filament into a mesh, the mesh after its bonding, thermal bonding, chemical bonding, or mechanical reinforcement method, so that the mesh non-woven fabric is high strength, good high Characterized by temperature resistance (can be used in 150 ℃ environments for a long time), aging resistance, UV resistance, high elongation, good durability and air permeability, corrosion resistance, sound insulation, insect-proof, non-toxic.
Spunbonded non-woven fabric process flow:
Polymer (polypropylene {{0} return material) -High-temperature melt extrusion of large screw straws -Filter -Metering pump (quantitative transmission) -Spinning (spinning inlet up and down drawing and pumping) -Cooling -Airflow traction -Mesh screen in mesh- Upper and lower pressure roller (pre-stressing)-Rolling mill Hot rolling (strengthening)-Rotating-Reverse cloth cutting-Weighing and packaging-Finished product storage.
Main applications of spun-bonded non-woven fabrics:
1. Medical and healthcare: such as disposable medical supplies, protective clothing, diapers, sanitary napkins, and personal healthcare supplies.
2. Packaging materials and lining materials: such as all kinds of shopping bags, storage bags, packaging bags, household goods, and lining materials.
3. Agricultural covering materials: used as sunscreen, pest control, cold and heat preservation, moisture covering film, grass and cropping film, etc.
