Spunbonded nonwovens are formed by continuous filaments laid in a random manner on a moving conveyor belt. In a typical spunbond process, the resin particles are heat treated to melt and then fed through a spinneret to produce tens of thousands of elongated filaments, and a fluid jet (such as air) causes the fibers to Stretched, then the fibers are blown or transported to a moving web where the fibers are laid in a random pattern and drawn onto the web to form a fabric, which then passes through a fabric Bonding position.

The bonding position generally comprises a light roller and a bonding roller (flower roller), and the irregular fiber fabric forms a series of identical convex spots on the nonwoven fabric after passing through the bonding roller (sticky) Joint point). The existing adhesive structure requires high bonding pressure, and the nonwoven fabric produced is not bulky and soft.

SUMMARY OF THE INVENTION The object of the present invention is to overcome the deficiencies of the prior art and to provide a spunbonded nonwoven fabric production process which achieves a fluffy and soft modified nonwoven fabric.

Spunbonded nonwoven fabric production process, including polypropylene (PP) - heating and melting - filtration - metering - split spinning - cooling drafting - splitting wire laying - rolling mill thermal bonding - winding slitting - packaging into The library process, specifically includes:

1) Polypropylene (PP) is pumped to the loading system of the large screw extruder through a vacuum device, and the polypropylene enters the large screw extruder by gravity;

2) The large screw extruder melts and mixes the polypropylene and gradually transports it forward to the filtration device of the melt;

3) The filtering device filters out the impurities affecting the spinning in the polypropylene, and the melt is accurately metered by the metering pump, and the melt is conveyed to the spinning die according to the set amount;

4) The melt passes through the distribution plate on the spinning die to keep the flow rate of the melt at each position consistent. After the melt enters the spinneret, the melt is spun into the raw fibers through the orifice of the spinneret due to the pressure;

5) the fiber is cooled and drawn by cold air, and the fiber is gradually cooled and stretched to obtain a desired fiber;

6) continuous fibers are scattered on the forward running mesh belt under the air separation of the yarn splitter to form a fiber web;

7) After the fiber web passes through the hot rolling mill, the fiber web is subjected to local melt hot rolling to impart a certain strength to the fiber web to form a nonwoven fabric;

8) The continuous non-woven fabric is wound into a roll by a winder, and is cut according to the user's requirements, and then packaged and stored in the warehouse.

Qingdao Runjuxiang Machinery 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.
