What is the important material of spunbonded non-woven fabric? How is spunbonded non-woven fabric made?

The important materials of spunbonded non-woven fabrics are polyester and polypropylene.

The important products of spunbonded non-woven fabrics are polypropylene, polyester (long fiber, short fiber) non-woven fabrics, and the most common operation we see is non-woven bags, non-woven packaging, etc. The identification of spunbonded nonwovens is easier, the individual bidirectional fastness is good, and the rolling point of individual spunbonded nonwovens is diamond shaped. The level of operation can also be made of flower packaging cloth, luggage cloth, etc., wear resistance, stable feel good, etc., so that he becomes the best choice to build such products.

Process: Polypropylene: polymer (polypropylene + feedback) - large screw rod low temperature melt extrusion - filter - metering pump (quantitative transport) - spinning (spinning inlet high and low tensile suction) - cooling - air traction - mesh curtain into mesh - high and low pressure roller (pre-reinforcement) - rolling mill hot rolling (reinforcement) - winding - reverse cloth sashing - weighing packaging - products into storage Polyester: Finished polyester slicing - large screw rod melt extrusion at low temperature - filter - metering pump (quantitative transport) - spinning (spinning inlet high and low tensile suction) - cooling - air traction - mesh curtain into mesh - high and low pressure roller (pre-reinforcement) - rolling mill hot rolling (reinforcement) - winding - inverted cloth sashing - weighing packaging - products into the warehouse spunbond non-woven performance And features: pp spunbonded non-woven fabric comprehensive strength is high, the general situation is greasy and fleecy, soft feel, folding and wear-resistant, good light permeability, excellent water absorption and oiliness, while heat resistance, acid resistance, alkali resistance, mildew and mothproofing, good size imchangeability, easy processing, easy to receive and receive.
