Producing polypropylene high-strength yarn essentially involves the processes of melting, extruding, cooling, and stretching of polypropylene pellets. To achieve the "high-strength" performance standard, the key lies in the parameter coordination during the spinning and stretching processes. The selection of the melt index of the raw materials needs to be done carefully. The PP pellets used for high-strength filaments have their fluidity controlled within a certain range to ensure that the molten material forms a uniform fine stream when it is extruded from the spinneret.
The physical properties of polypropylene high-strength yarns determine their stable demand in multiple specialized markets. Observing several major application areas can help understand the value of this product.
Scene 1: Luggage Straps and Binding Materials
This is one of the markets where polypropylene strong filament is used in large quantities. The puller covers of luggage, the shoulder straps of backpacks, and the handle straps of handbags - these parts are frequently stretched and bent during daily use. Using straps woven from strong polypropylene filament has the advantage of low density, being much lighter than polyester straps of the same volume, reducing the overall weight of the luggage. At the same time, its wear resistance can meet the usage intensity of general outdoor activities. Many luggage accessory factories in Guangdong and Fujian use it as a standard raw material for woven straps.
Scene 2: Home Textiles and Sofa Accessories
In the home furnishing industry, polypropylene strong yarn is commonly used for sofa bottom fabric and mattress edging. The sofa bottom fabric needs to balance cost and durability. Ordinary polyester bottom fabric is prone to mold when exposed to moisture, while polypropylene does not absorb water and maintains its performance in humid environments. The mattress edging requires long-term resistance to the tension of springs. The low elongation property of polypropylene strong filament ensures that the edging does not significantly loosen after two years of use. These seemingly insignificant applications collectively support the stable market demand for polypropylene strong filament.
Scene 3: Industrial Filter Cloth
In industries such as chemical production, electroplating, and wastewater treatment, plate and frame filter presses require polypropylene filter cloth. The filter cloth made from Prong Strong fibers has good tolerance to acidic and alkaline solutions, especially in highly acidic environments. Its hydrophobic property makes it easier for the filter cake to be separated from the cloth surface, thereby improving the efficiency of the filtration process. Compared to single-fiber filter cloth, the Prong Strong fiber composite filter cloth has higher filtration accuracy and is suitable for intercepting tiny particles.
