Read about Polypropylene filament: Characteristics, production and multiple applications!


In the large family of fiber materials, polypropylene polypropylene fibers with its unique properties and wide applications, occupy an important place. Today, we're going to take a closer look at this amazing material.


First, what is polypropylene Polypropylene filament?


Polypropylene Puqiang, you know it's related to polypropylene by the name. Yeah, he's one of the big guns in the Polypropylene family. Polypropylene fiber, that is, polypropylene fiber, and polypropylene polypropylene fiber is a kind of polypropylene fiber with high strength after special process treatment. Its strength is much higher than ordinary polypropylene fiber, which is also the origin of its name "Puqiang". From the appearance, it is similar to ordinary fiber, thin and long, but it contains powerful energy.


Second, the unique performance of the big reveal


High strength: The strength of polypropylene polypropylene filament is considerable, which makes it in many occasions that need to withstand greater tension. For example, in the production of industrial ropes, safety belts and other products, it can easily cope with, to ensure the safety and reliability of the use process. Compared with some other fiber materials, its strength advantage is very obvious, and it can withstand greater external forces without breaking.


Light weight: polypropylene itself is a less dense fiber, and polypropylene polypropylene filament also inherits this advantage. Light weight is very important in many application scenarios, such as in the aerospace field, the use of lightweight materials can reduce the weight of the aircraft, thereby reducing energy consumption and improving flight performance. In daily life, some of the backpacks we use, travel bags, etc., if the webbing made of polypropylene polypropylene silk is not only strong and durable, but also more portable.


Good wear resistance: It has excellent wear resistance and is not easy to damage after a long time of friction. This feature makes it widely used in some products that are often subjected to friction, such as car seat belts, shoe LACES and so on. These products will frequently rub with other objects in daily use, and polypropylene polypropylene filament can withstand the test and extend the service life of the product.


Strong chemical resistance: polypropylene filament has good tolerance to acid, alkali and other chemical substances. In some chemical, agricultural and other fields, often come into contact with a variety of chemical reagents, the use of polypropylene polypropylene filaments made of filtration materials, protective supplies, etc., can effectively resist the erosion of chemical substances, to ensure the performance and use of products.


Small hygroscopic: it almost does not absorb water, which makes the product made with it can maintain good performance in a humid environment. For example, in outdoor goods, such as tents, tarps, etc., if the polypropylene polypropylene wire is used, even in rainy days, it can be quickly drained, and will not become heavy because of the absorption of water, affecting the use of.


Third, production process analysis


Raw material preparation: The main raw material for the production of polypropylene polypropylene filament is polypropylene resin, and some additives will be added, such as antioxidants, ultraviolet absorbers, etc., to improve the performance of the fiber. These raw materials need to go through strict screening and inspection to ensure that the quality meets the production requirements.


Melt extrusion: The prepared raw material is fed into the screw extruder, and the polypropylene resin is melted at high temperature. The screw extruder pushes the molten raw material forward through the rotation of the screw, and controls the extrusion amount of the raw material through a precise metering pump. The molten material is then extruded through a spinneret with a specific aperture to form a fine filament-like stream of melt.


Drafting and cooling: The just-extruded melt is still soft and needs to be drafted. Through the drafting device, the melt flow is stretched to a certain multiple to make its diameter thinner, and the molecular chain is also oriented to improve the strength of the fiber. In the process of drafting, it is also necessary to cool the fiber so that it can be cured quickly. There are usually two cooling methods: air cooling and water cooling, and different cooling methods will have a certain impact on the performance of the fiber.


Post-treatment: After being drawn and cooled, the fiber also needs to undergo some post-treatment processes, such as twisting and oiling. Twisting can improve the adhesion of fiber and make it more stable in the subsequent processing. The oil can reduce the friction between the fiber and the equipment and improve the workability of the fiber. Finally, the treated polypropylene fiber is wound to form a finished product.


4. Multiple application scenarios


Civil field: In our daily life, polypropylene Puqiang wire can be seen everywhere. Like backpack straps, shoelaces, mobile phone straps, etc., many are made of polypropylene Puqiang silk. Its high strength and wear resistance ensure that these products are not easily damaged during long-term use. In addition, in some household items, such as curtains, sofa covers, etc., polypropylene polypropylene wire will also be used to increase the strength and durability of the product.


Industrial field: In industrial production, polypropylene fiber is playing an important role. For example, in the packaging industry, it is widely used to make a variety of packaging belts, ropes, etc., for binding and fixing goods to ensure the safety of goods during transportation and storage. In the field of construction, polypropylene polypropylene fibers can be used to make geotextiles, which are used to strengthen soil and prevent soil erosion. In the automobile manufacturing industry, it can be used to make automobile seat belts, interior materials, etc., to improve the safety and comfort of automobiles.


Sporting goods field: Due to the high strength and lightweight characteristics of polypropylene polypropylene filament, it is also widely used in the field of sporting goods. Products such as climbing ropes, safety nets, sports backpacks and so on are inseparable from polypropylene. It can provide reliable protection for athletes, while reducing the weight of equipment, so that athletes in the exercise process more relaxed.


Other areas: In addition to the above areas, polypropylene Polypropylene filament is also used in agriculture, fisheries and other fields. In agriculture, it can be used to make insect-proof nets, greenhouse covering materials, etc. In the fishing industry, it can be used to make fishing nets, ropes, etc., to improve the service life and performance of fishing gear.


With its unique properties and diverse applications, polypropylene fiber has become an indispensable fiber material in modern industry and life. With the continuous progress of science and technology, I believe that polypropylene will play a greater role in more fields, bringing more convenience and surprises to our lives.
