Polypropylene hollow filament: A fiber material with characteristics and applications!

Polypropylene hollow filament is a special kind of chemical fiber, which has a unique structure and forms a continuous hollow tubular space inside the fiber. This special structure gives it many excellent properties, so that it can be widely used in many fields.

In the production process, special spinneret and spinning technology are usually used to manufacture polypropylene hollow yarn. By precisely controlling the parameters of temperature, pressure and melt flow during spinning, it is ensured that the thin flow of melt extruded from the spinneret can form fibers with hollow structure. In the production process, the control of the process is very critical, and a slight deviation may affect the integrity and uniformity of the hollow structure, and then affect the performance of the fiber.

The performance advantage of polypropylene hollow filament is obvious. First of all, because of its internal hollow, with light weight, this feature makes the use of polypropylene hollow wire products to ensure strength at the same time, can effectively reduce the overall weight. Secondly, the hollow structure gives it good thermal performance, the air in the hollow part to form a insulation layer, hinder heat transfer, the thermal effect is better than ordinary solid fiber. In addition, polypropylene itself has the characteristics of chemical corrosion resistance, hollow wire also inherited this advantage, can remain stable in a variety of chemical environments, not easy to be eroded.

Based on these characteristics, polypropylene hollow fibers are widely used. In the field of home textiles, it is often used to make warm quilt core, mattress filler, etc., and its good warmth and lightness bring people a comfortable and warm sleep experience. In terms of industrial textiles, it can be used to manufacture filter materials, which can effectively filter impurities in liquids or gases with hollow structure and chemical stability, and have a long service life. In some special agricultural covering materials, you can also see the figure of polypropylene hollow silk, which can play a certain role in insulation and moisturizing, and because of its chemical stability, it will not have adverse effects on soil and crops.

With its unique structure and excellent performance, polypropylene hollow wire plays an important role in many industries, providing strong support for the performance improvement and application expansion of related products.

Shanghai Jinci Industrial Co., Ltd. was established in March 2006, including polypropylene general strong yarn, polypropylene high strength yarn, polypropylene anti-aging yarn, polypropylene twist yarn, polypropylene hollow yarn, polypropylene fluorescent silk, polypropylene luminous silk, polypropylene flame retardant silk, polypropylene air change yarn, polypropylene waterproof yarn, etc. Color based, with a number of fast prototypes, according to requirements, accurate, timely tailored products for customers. Since the factory opened, it has developed and produced tens of thousands of products with different specifications and colors. Wide range of product densification. Raw silk products 300D-3000D.
