Why is Polypropylene high-strength fibre widely used in the industrial weaving field?
In the field of industrial weaving, the selection of materials directly affects the performance and service life of the final products. Polypropylene high-strength fibre, as a common type of polypropylene filament, has seen a continuous increase in its application share in areas such as safety nets, conveyor belts, and fire hoses in recent years.
From a physical perspective, the fineness specifications of Polypropylene high-strength fibres currently available on the market mainly fall within the range of 250d to 2000d. The strength of filaments of this specification typically reaches above 8.5g/d, while the elongation at break is controlled within the range of 15% to 20%. In industrial applications, the balance between strength and elongation is quite ideal, as it can withstand significant tension while also having a certain degree of shock absorption. For example, in the production of lifting and hoisting belts, Polypropylene high-strength fibres have a relatively light weight, allowing them to float on the water surface. This is a practical feature for dock operations or emergency rescue equipment.
Apart from mechanical properties, chemical resistance and thermal stability are also important indicators for industrial users. During the manufacturing process of polypropylene high-strength yarns, through process adjustments, their dry heat shrinkage rate can be controlled within 5% at 130℃. This means that when used in long-term outdoor conditions or in complex industrial environments, the size stability of the tarpaulins or filter cloths made from it is better, and they are less likely to become brittle or deformed due to temperature changes or contact with acidic or alkaline substances.
The improvement of the production process is also one of the reasons for its application. By using specific polypropylene resins in combination with a two-stage stretching process, uniform filament with high strength can be produced. This production route not only reduces the equipment investment cost but also makes the twisting uniformity of the multifilament higher, meeting the requirements of high-speed weaving on industrial looms.
Jiangyin Jinmeng Textile Co., Ltd. is a manufacturing enterprise specializing in high-strength polypropylene industrial yarn, polypropylene luminous yarn, polypropylene UV-resistant fabric strips, polypropylene flame-retardant fabric strips, polypropylene fabric strips, polypropylene threads, polyester threads, and other products. It is located in the Yuntin Street Industrial Park of Jiangyin City, which is adjacent to Taihu Lake and facing the Yangtze River. The transportation here is very convenient.
Polypropylene high-strength fibres possess the advantages of being environmentally friendly, non-toxic, resistant to acids and alkalis, having a low specific gravity, a small thermal shrinkage rate, low thermal conductivity, less static accumulation, and almost no moisture absorption. The product has great potential in industrial yarns and can be widely used in industries such as industrial belts, safety belts, conveyor belts, woven geotextiles, filter cloths, sail cloths, filament production, ropes and cables, and cables, etc. It is a novel textile material that can partially replace nylon and polyester.
