High strength polypropylene double twisted yarn professional manufacturer - Tongjia!

High strength polypropylene double twisted yarn is a type of polypropylene yarn product that has undergone special processing technology and has many excellent characteristics and wide application fields. The following is a detailed introduction about it:

Production process:

Raw material selection: Polypropylene is the main raw material, which undergoes strict screening and processing to ensure the purity and quality of the raw materials. Polypropylene has the characteristics of narrow relative molecular weight distribution and high crystallinity, providing a good foundation for the production of high-strength polypropylene fibers.

Spinning process: Advanced spinning equipment and technology are used to heat and melt polypropylene raw materials, which are then extruded through a spinneret to form continuous polypropylene filaments. During the spinning process, parameters such as temperature, pressure, and extrusion speed are strictly controlled to ensure the quality and performance of the silk.

Double twisting treatment: Twist the spun polypropylene filament through a double twisting machine. The working principle of the double twisting machine is to twist the yarn under a certain tension through the rotation of the spindle and the traction of the yarn. After double twisting treatment, the strength, wear resistance, and fatigue resistance of polypropylene yarn

The performance such as fatigue has been significantly improved.

characteristic:

High strength: This is one of the most prominent characteristics of High strength polypropylene double twisted yarn. Its strength is much higher than that of ordinary polypropylene yarn, capable of withstanding greater tensile and compressive forces, and not easily broken. Therefore, in some fields that require high material strength, such as seat belts, safety ropes, industrial harnesses, etc., high-strength

High strength polypropylene double twisted yarn has obvious advantages.

Lightweight: Polypropylene fiber has the lowest density among all synthetic fibers, so high-strength polypropylene double twisted yarn is lightweight, easy to transport and process, and also reduces the burden during use.

Small and uniform thermal shrinkage: During the heating process, the shrinkage rate of high-strength polypropylene double twisted yarn is small and uniform, which can ensure the dimensional stability and quality of the product. This characteristic has made it widely used in some fields that require high dimensional accuracy, such as textile fabrics, industrial fabrics, etc

Universal application.

Flame retardant and anti-aging: It has good flame retardant performance, which can prevent the spread of flame to a certain extent and improve the safety of use. At the same time, after special anti-aging treatment, it is not easy to age and deteriorate during long-term use, and has a long service life.

Wear resistance and seawater corrosion resistance: High strength polypropylene double twisted yarn has good wear resistance and can withstand the test of friction and wear. In addition, it also has good resistance to seawater corrosion and has broad application prospects in fields such as marine engineering and shipbuilding.

Application areas:

Industrial field: widely used in the manufacturing of industrial lifting belts, cables, container bags, conveyor belts and other products. For example, in ports, docks, and other places, suspenders and cables made of high-strength polypropylene double twisted yarn can withstand the lifting and traction of heavy objects, ensuring safety and reliability; In mines, factories, and other places

Therefore, conveyor belts need to have high strength and wear resistance, and high-strength polypropylene double twisted yarn is an ideal material choice.

In the field of safety protection: Due to its high strength and flame retardant properties, it is commonly used in the production of safety nets, seat belts, safety ropes and other safety protection equipment. In construction and high-altitude operations, these safety protective equipment can provide effective protection for workers.

Textile field: can be used to manufacture functional textiles, such as sportswear, outdoor clothing, etc. These garments need to have good wear resistance, breathability, and lightness, and high-strength polypropylene double twisted yarn can meet these requirements, providing consumers with a comfortable wearing experience.

Suining County Tongjia Chemical Fiber Factory was founded in 2013, the main products 300D-3000D color high strength polypropylene yarn, polypropylene double twist, polypropylene industrial silk, polypropylene high-strength silk, etc., the products have high strength, light weight, heat reduction uniform, flame retardant, anti-aging, low thermal conductivity, are widely used in a variety of industrial cloth, cable, container bag, anti-cracking engineering fiber and other products.
