High-tenacity Polypropylene Network Yarn is a kind of polypropylene fiber made through a special spinning process. It has the characteristics of High strength, corrosion resistance and lightweight, and is widely used in the fields of industry, construction, medical care and special textiles. Compared with traditional polypropylene filament, its unique network structure endows it with superior mechanical properties and processing adaptability. This article will objectively analyze the technical value and market potential of high-strength polypropylene network filament from aspects such as material properties, production processes, application fields and future development trends.
I. Core Characteristics of High-strength Polypropylene Network Filament
High strength and low elongation
Breaking strength: It can reach 6-8 CN /dtex, approaching the level of some polyester industrial filaments, and is suitable for high-load scenarios.
Low creep: The molecular chain orientation is high, and the deformation is small under long-term force, making it suitable for long-term load-bearing applications such as ropes and lifting slings.
2. Lightweight and chemical resistance
With a density of only 0.91g/cm, it is lighter than polyester (1.38g/cm) and nylon (1.14g/cm), which can reduce the weight of the end product.
It is resistant to acids and alkalis and mold, and performs exceptionally well in Marine engineering and chemical environments.
3. Advantages of network node structure
Through high-speed airflow network technology, physical cross-linking points are formed between fibers, endowing them with:
Direct weaving without sizing reduces the post-treatment process;
Good bundling property reduces the rate of fuzz and breakage during processing.
Iii. Key Points of the production process
The production of high-strength polypropylene web filaments requires the combination of high-orientation spinning and web processing technologies. The core processes include:
High-magnification stretching process: Multi-stage hot stretching (stretching ratio 5-8 times) is adopted to enhance the regularity of molecular chain arrangement.
Online network node formation: Before winding, the filament is blown through a compressed air nozzle to form uniform network points (the node spacing is usually 10-50cm).
Low-temperature setting control: To prevent excessive thermal stress from causing fiber shrinkage and ensure dimensional stability.
Technical difficulty: Control of network uniformity, which requires balancing air pressure, filament speed and fiber tension.
Iv. Innovative Application Scenarios
1. Industrial field
Marine ropes and fishing nets: Resistant to salt water corrosion, with a strength retention rate of over 90% (after UV treatment).
Geogrids: Used for reinforcing soft foundations, they can replace some steel wire materials and reduce project costs.
2. Safety protection
Cut-resistant gloves: Blended with aramid, balancing lightness and protection level (EN388 standard).
High-altitude work safety belts: They are 20% lighter than polyester products and are less prone to aging.
3. Healthcare and Environmental Protection
Absorbable sutures: Achieve biocompatibility through modification and are applied in non-load-bearing wound suturing.
Filter material: Hollow network wire structure enhances the efficiency of sewage filtration (retention rate ≥95%).
