Shanghai Jinci Industrial Polypropylene Filament: The fusion of craftsmanship and quality, the support of diverse applications!

In the field of chemical fiber materials, Polypropylene Filament holds an important position due to its unique properties. Shanghai Jinci Industrial Co., Ltd. specializes in the production of polypropylene filament. With its exquisite craftsmanship and strict quality control, it has created high-quality polypropylene filament products that are widely used in multiple industries.

Polypropylene filament, also known as polypropylene fiber filament, is spun from isotactic polypropylene obtained by the polymerization of propylene. Shanghai Jinci Industrial is extremely strict in the selection of raw materials, carefully choosing high-quality polypropylene resin to ensure its high purity, good fluidity and stable molecular structure, laying a solid foundation for the production of high-quality polypropylene filament.

During the production process, the company employs advanced melt spinning technology. First, put the polypropylene raw materials into a high-temperature environment to rapidly melt them into a uniform melt. This stage has extremely high requirements for temperature control, which needs to be precisely maintained within a specific range, generally 50-130 °C higher than the melting point of polypropylene, that is, 260-300 °C, to ensure the ideal fluidity of the melt and facilitate subsequent spinneret operations. Then, the melt is extruded through a precision spinneret to form extremely fine filaments. The quality and design of the spinneret directly affect the uniformity and quality of the filament. The spinnerets adopted by Shanghai Jinci Industrial are carefully manufactured, with evenly and smoothly distributed holes, which can ensure the uniform extrusion of the melt and guarantee that the initial state of each filament is consistent.

After the filament is extruded, it immediately enters the cooling process. Due to the relatively fast crystallization rate of polypropylene during cooling and molding, Shanghai Jinci Industrial strictly controls the cooling temperature and speed. Generally, the cooling temperature is lower than that of polyester and nylon to prevent excessive crystallinity from affecting subsequent processing. By precisely controlling the cooling conditions, the filament can solidify rapidly and achieve an appropriate degree of crystallinity and orientation, laying a foundation for the subsequent stretching process. During the stretching process, the internal structure of the filament is further adjusted to enhance the strength and toughness of the fibers. Under the action of specific temperature and tension, the molecular chains are highly oriented along the fiber axis, thereby enhancing the physical properties of polypropylene filament.

The Polypropylene Filament produced by Shanghai Jinci Industrial has many outstanding properties. It is lightweight, with a density of only 0.90-0.92g /cm³, making it the lightest variety among common chemical fibers. It is 20% lighter than nylon and 30% lighter than polyester. This characteristic gives it a significant advantage in fields with strict weight requirements, such as aerospace fabrics and lightweight outdoor sports equipment. The hygroscopicity of polypropylene filament is extremely low, and its moisture regain rate is nearly zero under normal atmospheric conditions. This not only endows it with excellent waterproof performance, effectively preventing water penetration when used to make waterproof fabrics, rain gear and other products, but also makes polypropylene filament fabrics easy to wash and dry quickly, making them suitable for daily wear and frequently used textiles. In addition, the mechanical strength of polypropylene filament is quite high, with almost equal dry and wet strength and elongation at break. It also has excellent wear resistance, especially a long service life against repeated bending. At a break Angle of 175°, it can withstand 200,000 repeated bends. This makes it perform exceptionally well in the manufacturing of industrial ropes, lifting slings, fishing nets and other products that need to withstand significant external forces and frequent friction. Meanwhile, polypropylene filament also has excellent chemical resistance. Except for strong corrosive substances such as concentrated nitric acid and concentrated caustic soda, it has strong resistance to most acids, alkalis and other chemical agents. It is suitable for making filter materials, chemical fabrics, etc., and can maintain stable performance in harsh chemical environments.

Based on these excellent properties, the polypropylene filament of Shanghai Jinci Industrial has an extremely wide range of applications. In the textile industry, it can be made into various types of clothing fabrics. When blended with other fibers, it can add unique properties to the fabric. For example, when blended with cotton fibers, it can enhance the quick-drying property and wear resistance of the fabric. When making home textile products such as curtains and bedding, the waterproof and stain-resistant properties of polypropylene filament can extend the service life of the products and reduce maintenance costs. In the industrial field, polypropylene filament is used to manufacture geotextiles, which play roles such as reinforcement, protection and filtration in the construction of roads, DAMS and other projects. It can also be made into industrial filter cloth. In the liquid and gas filtration links of the chemical, food, pharmaceutical and other industries, it can efficiently intercept impurities with its chemical corrosion resistance and high strength, ensuring the smooth progress of the production process and product quality. In the field of medical and health care, non-woven fabric made of polypropylene filament can be used in disposable medical supplies such as surgical gowns and masks. Its excellent breathability and barrier properties not only provide a comfortable experience for medical staff and patients but also effectively prevent the spread of bacteria, safeguarding health and safety.
