Polypropylene industrial silk is a synthetic fiber made from polypropylene. Due to its unique performance characteristics, it holds an important position in the industrial field. The following is an introduction from three aspects: performance advantages, production processes, and application fields.

I. Performance Advantages

The core advantage of polypropylene industrial filament lies in its lightweight and high-strength characteristics. Its density is only 0.90-0.92 g/cm, making it the lightest variety among common chemical fibers, even lighter than polyester and nylon. This characteristic gives it an advantage in applications where weight reduction is required. Meanwhile, the strength of polypropylene industrial filament is outstanding, with a breaking strength of 5 to 8 grams per denier. Moreover, its wet strength is basically the same as its dry strength, making it particularly suitable for products with high strength requirements such as ropes and fishing nets.

In addition, polypropylene industrial silk also has chemical corrosion resistance and a good resistance to acids, alkalis and other chemicals, making it suitable for filter materials and packaging materials. Its wear resistance and low moisture absorption also make it stable in damp or frictional environments, such as being widely used in products like geotextiles and safety belts. However, the heat resistance and light resistance of polypropylene are relatively poor and need to be improved by adding anti-aging agents.

Ii. Production Process

The production of polypropylene industrial filament mainly consists of two processes: one-step spinning and two-step spinning. The one-step spinning process has the characteristics of short flow and low cost, but the strength of the fibers produced is relatively low. Two-step spinning, through multi-stage stretching and heat treatment, can produce products with higher strength, which are more suitable for industrial applications.

In recent years, the quality of polypropylene industrial filament has been improved through the application of new technologies such as masterbatch melt injection. This method involves melting colored or functional masterbatches (such as flame-retardant and antistatic masterbatches) through an independent screw and then injecting them into the main spinning system to reduce masterbatch degradation and maintain good physical properties of the fibers. In addition, the development of fine denier and ultra-fine denier polypropylene filaments has further expanded their application fields, such as for high-tech products like lithium battery separators.

Iii. Application Fields

The application scope ofpolypropylene industrial silk is extensive, covering multiple industrial fields:

Thread products: Used for sewing woven bags, shoe material threads, luggage threads, etc. With features such as low price, high strength and corrosion resistance, they can replace traditional materials.

Rope and net products: including construction safety nets, fishing nets and sports nets. Due to their light weight, high strength and wear resistance, they ensure safe use.

Belt products: such as flexible bulk bags, safety belts and fire hoses, by taking advantage of their high strength and low elongation, meet the requirements for safety factors.

Industrial fabrics: including geotextiles, filter fabrics and cord fabrics, play a role in reinforcement and filtration in infrastructure construction (such as DAMS and expressways).

Emerging fields: Through modification technology, polypropylene industrial filament can also be used in functional products such as medical and health care (such as surgical gowns) and new energy (such as battery separators), demonstrating development potential.
