The process flow of polypropylene FDY network yarn!

polypropylene FDY network yarn is a type of polypropylene filament that has undergone special processing. The following is a detailed introduction about it:

Production process:

In the production process of polypropylene FDY (fully stretched filament) network filament, the filament passes through the network nozzle. Under the action of the jet airflow, the single filaments bond to each other, forming a periodic network of points. This network processing intertwines the monofilaments, increasing the adhesion and stability of the fiber bundle.

According to the number and distribution density of network points, network fibers can be divided into different types such as microgrids, light nets, and heavy nets. For example, a microgrid has about 3 network points within a length of 10 centimeters; There are about 5 network points within 10 centimeters of the lightweight mesh; There are 8 or more network points within a length of 10 centimeters in the heavy net type.

characteristic:

High strength: Polypropylene itself has high strength. After full stretching process and network processing, the strength of polypropylene FDY network yarn is further improved, making it more stable and durable when subjected to tension. It can be used for products with high strength requirements, such as ropes, woven belts, etc.

UV resistance: Polypropylene material has good UV resistance performance. The specially treated polypropylene FDY network yarn can effectively resist UV erosion when used outdoors, and is not easy to age and fade. It is suitable for outdoor products and products exposed to sunlight for a long time.

Good adhesion: Network processing enables the single fibers in the filament bundle to bond with each other, increasing the adhesion of the filament bundle and making it less prone to unraveling during textile processing, thereby improving production efficiency and product quality.

Lightweight: Polypropylene has the lowest density among all synthetic fibers, so polypropylene FDY network fibers are lightweight and can reduce the overall weight of the product. They are suitable for products with strict weight requirements, such as components in aerospace, automotive and other fields.

Application areas:

Ribbon industry: can be used to produce various types of ribbons, such as backpack straps, seat belts, clothing accessory straps, etc. Its high strength and good grip make the webbing have good load-bearing capacity and durability.

Rope industry: used for manufacturing ropes, such as lifting ropes, traction ropes, climbing ropes, etc. The high strength and UV resistance ensure the safety and service life of the rope in various complex environments.

Wig industry: Due to its lightweight, softness, and certain toughness, it can be used to make wigs, providing a natural appearance and comfortable wearing experience.

In the field of geotechnical materials, it can be used to produce geotextiles, geogrids and other geotechnical materials, playing an important role in soil reinforcement, water conservancy engineering, road construction and other aspects.
