Polypropylene High strength filament - excellent textile material!

Polypropylene high strength yarn is a kind of synthetic fiber material with excellent performance.

I. Characteristics

High strength

With very high strength, its strength can be compared with polyester fiber, nylon and other high-performance fibers. This makes polypropylene high strength filaments perform well in applications that require greater tension.

For example, in the fields of ropes, safety belts, lifting belts, etc., polypropylene high-strength yarn can provide reliable strength assurance.

Low density

Polypropylene is one of the least dense of all synthetic fibers, which makes polypropylene high strength yarn with a light weight. In some applications with strict weight requirements, such as aerospace, outdoor sports equipment, etc., polypropylene high-strength yarn becomes the ideal choice.

Corrosion resistance

It has good tolerance to acid, alkali and other chemicals, and can be used in harsh environments for a long time. This feature makes polypropylene high strength filament widely used in chemical industry, Marine and other fields.

Abrasion resistance

It has good wear resistance and can withstand friction and wear. In some applications that require frequent friction, such as carpets, conveyor belts, etc., polypropylene high-strength yarn can maintain a long service life.

Good insulation

Polypropylene high strength filament has good insulation properties and can be used in electrical insulation materials and other fields.

Second, the production process

High strength polypropylene filament is usually produced by melt spinning. The specific process is as follows:

Raw material preparation

The polypropylene resin particles are dried to remove moisture and impurities to ensure a smooth spinning process.

Melt extrusion

The dried polypropylene resin particles are heated to a molten state, and the molten resin is extruded into filaments by a screw extruder.

Cooling forming

The extruded filaments are cooled by a cooling device so that they can be cured quickly.

stretch

The cooled filaments are stretched to improve the strength and orientation of the fibers. The drawing process is usually carried out on a multistage drawing machine, and the properties of the fiber are optimized by gradually increasing the drawing multiple.

Heat setting

After stretching, the fibers are heat-shaped to eliminate internal stress and improve the dimensional stability and performance stability of the fibers.

wind

The heat-set high strength polypropylene filament is wound into canisters for easy storage and transportation.
