Introduction of polypropylene high strength filament!

Polypropylene high strength yarn refers to the polypropylene composite yarn with a breaking strength greater than 6cN/dtex. Here's what to know about it:

peculiarity

High strength: has a high breaking strength, made of rope, net and other products durable, can withstand greater tension.

Light weight: relatively small density, light texture, easy to handle and use, for example, in the production of geotextiles, light weight makes it more convenient to lay.

Good wear resistance: It has good wear resistance and can be used to make items that need to be used for a long time and are easy to wear, such as filter cloth and canvas.

Strong chemical resistance: It has good stability to high concentrations of acids and alkalis and common chemicals, and can maintain performance in harsh chemical environments. It is suitable for filtration and protective materials in chemical and environmental protection industries.

Small thermal shrinkage: good dimensional stability, under different temperature conditions, its shape and size change is small, is conducive to ensuring the quality and performance of the product.

Low thermal conductivity: It has a low thermal conductivity and can be used to make some materials that need heat insulation.

Almost non-hygroscopic: small hygroscopic, not easy to be damp, can maintain performance in a humid environment, such as in the production of ropes, fishing nets, not easy to affect the strength and weight due to water absorption.

Production process: two-step and one-step spinning process can be used. The two-step process first spun to produce undrawn silk, and then after stretching and other post-treatment processes to obtain high-strength silk, the resulting silk fracture strength is high, up to 6-8cN /dtex. The one-step method is to continuously complete the spinning and drawing processes on a single device, which has low energy consumption, but the produced silk strength is roughly 5-7cN /dtex.

Application field

Rope nets: Used in the manufacture of construction, transportation, agriculture, fishing, sports nets and ropes, such as safety nets, lifting belts, etc., using its high breaking strength, wear resistance, corrosion resistance, light safety characteristics.

Thread: The polypropylene wire made of low price, high strength, anti-aging, wear resistance, seawater corrosion resistance, good elasticity, mainly used in sewing cement bags, fertilizer bags, plastic woven bags, fishing net weaving and other industries.

Cloth type: woven geotextile suitable for road, railway, airport, seawall and other engineering projects; Made of high-strength polypropylene fiber filter cloth, mainly used in metallurgy, mineral processing, chemical industry, light industry, food, environmental protection and other industries, using its acid and alkali resistance, corrosion resistance, high strength, no water absorption, light weight, good stability, good filter stripping and other advantages.

Other: can also be used to make high pressure fire hose, seat belts, container bags and other products with high safety requirements.
