Spunbond non-woven fabric: after extruding and stretching the polymer to form continuous filaments, the filaments are laid into a net, and the web is then subjected to self-bonding, thermal bonding, chemical bonding or mechanical reinforcement to make the web It becomes non-woven fabric.

It has good high temperature resistance and high temperature resistance (polypropylene can be used for a long time in 150 °C environment, polyester can be used for a long time in 260 °C environment), aging resistance, UV resistance, high elongation, stability and permeability. Corrosion resistant, soundproof, anti-mite, non-toxic.

Process flow

Polypropylene: polymer (polypropylene + return material) - large screw high temperature melt extrusion - filter - metering pump (quantitative delivery) - spinning (spinning inlet up and down stretching suction) - cooling - Airflow traction - mesh curtain netting - upper and lower pressure roller (pre-reinforcement) - rolling mill hot rolling (reinforcement) - winding - inverted cloth cutting - weighing packaging - finished product storage

Polyester: Treated polyester chips - high-temperature melt extrusion of large snails - filter - metering pump (quantitative delivery) - spinning (spinning inlet up and down stretching) - cooling - air traction - Net curtain forming net - upper and lower pressure roller (pre-reinforcement) - hot rolling (reinforcement) of rolling mill - winding - inverted cloth cutting - weighing packaging - finished product storage

Its main purpose

The main materials of the spunbonded nonwoven fabric are polyester and polypropylene.

The main products of spunbonded non-woven fabrics are polypropylene, polyester (long-fiber, staple fiber) non-woven fabrics. The most common and most commonly used applications are non-woven bags, non-woven packaging, etc. The identification is easier, generally the two-way fastness is good, and the rolling point of the generally spunbonded nonwoven fabric is diamond-shaped.

The application level can also be used as a flower wrapping cloth, luggage cloth, etc., which is resistant to abrasion and firm hand feeling, and makes him the best choice for making such products.

Qingdao Runjuxiang Co., Ltd. was established in Wenzhou in 1998. With the development of the company and the expansion of its business, it moved to Qingdao in 2008 and established Qingdao Runjuxiang Machinery Co., Ltd. Up to now, only more than 200 sets of machining and manufacturing equipment, and equipped with professional testing equipment, have produced more than 200 production lines of polypropylene spunbonded non-woven fabrics.

Qingdao Runjuxiang Co., Ltd. has established a perfect after-sales service system, which eliminates the worries of customers, quick response, one-stop service, and aims to “satisfy customer needs”, and march forward and climb.
