SMMS PP Nonwoven Fabric Production Line Automatic

Nonwoven Fabric Making Machine High Quality SMMS PP Nonwoven Fabric Production Line

• Polypropylene nonwoven fabric making machine use polypropylene granule as raw material and get melting by high temp. extrusion machine. Nonwoven fabric production line produce fibers/filaments by the latest RF 4 spunbond / meltblown spinning technology in the world. All of long fibers/filaments are collected by high speed conveyor belt and uniform random; finally the uniformed fibers are thermal boned by calendar machine.
• The four-layer nonwoven fabric produced by SMMS Nonwoven Machine, like the SMS Nonwoven fabric, the meltblown nonwoven here is doubled.
• The SMMS is more symmetry, water repellency, bacterial resistance and durability than SMS.

The working process of the whole line is:

Feeding hopper--main extruder-- metering pump-- filter machine-- spinning box with spinneret-- drafting and distributing part--web-forming machine-- calender machine with pattern-- automatic winding and cutting machine

Advantages

1. Energy-saving:
All main motors of machine use Variable Frequency Motor(AC), eliminating three-phase asynchronous motors;
Variable Frequency Motor:
(1) Speed regulation is easy and energy saving.
(2) AC motor has simple structure, small volume, small inertia, low cost, easy maintenance and durability.
(3) It can expand output and achieve high speed and high voltage operation.
(4) Soft start and fast brake can be achieved.
(5) No spark, explosion-proof, and strong environmental adaptability.
2. High output:
Take "PP" material as an example, the PP material is tested on the customer's site, our machines' actual production output
is10%-20% higher than the same model in the market;
3. Simple installation:
The equipment is easy to install, only need to be connected to the inlet and outlet water, which can save 2 days of installation time.

The resin chips are fed into a screw extruder, heated and melted and extruded from a nozzle. The polymer melted at the exit of the die is subjected to high speed. At the same time, cold air comes from both sides of the die to cool and solidify the fibers to form ultra-fine short fibers. The effect of air flow, these short fibers are aggregated on the fiber collection device to form a web or core.The melt-blown process is a one-step process from thermoplastic resin slicing to making a fiber mesh belt (cloth / core tube).Therefore, the process is short, the product is formed in one step, and the production efficiency is high.By adjusting the combination of meltblown processes, different fiber structure (such as fiber diameter (0.5 ~ 3um), web pore size,etc.) can be achieved. The meltblown process is suitable for a wide range of raw materials and is suitable for processing variousmaterials such as polypropylene, polyester, and nylon. At present, polypropylene materials account for more than 95%.
