Spunbonded nonwoven fabric, the main material is polyester and polypropylene, high strength, good high temperature resistance
Spunbonded nonwoven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the web into a non-woven fabric.
Good high temperature resistance and low temperature resistance (polypropylene can be used for a long time in an environment of 150 °C, and polyester can be used in an environment of 260 °C for a long time), aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance , sound insulation, mothproof, non-toxic.
The main purpose
The main materials of spunbond nonwovens are polyester and polypropylene.
The main products of spunbond non-woven fabrics are polypropylene and polyester (long fiber, short fiber) non-woven fabrics. The most common and commonly used applications are non-woven bags, non-woven packaging, etc.; for spunbond non-woven fabrics It is easier to identify, and generally has good two-way fastness. Generally, the rolling point of spunbonded non-woven fabrics is diamond-shaped.
At the application level, it can also be used as flower wrapping cloth, bag cloth, etc., and its characteristics of wear resistance, firmness and good hand feeling make it the best choice for making such products.
process flow
Polypropylene: Polymer (polypropylene + return material) - large screw high temperature melt extrusion - filter - metering pump (quantitative delivery) - spinning (spinning entrance up and down stretching and suction) - cooling - Airflow traction—net curtain forming—upper and lower pressing rolls (pre-reinforcement)—rolling mill hot rolling (reinforcement)—winding—reverse fabric slitting—weighing and packaging—finished product storage
Polyester: processed polyester chips - large screw stalk high temperature melt extrusion - filter - metering pump (quantitative delivery) - spinning (spinning entrance stretched up and down suction) - cooling - air traction ——Mesh curtain forming——Upper and lower pressure rolls (pre-reinforcement)——Rolling mill hot rolling (reinforcement)——Coiling——Reversing and slitting——Weighing and packaging——Product storage.
