High strength wire is usually produced using melt spinning method. The polypropylene resin is added to the vertical or horizontal screw extruder heating melting, and the film is extruded by the spinneret by the metering pump, cooled in the air. The membrane cracked fibers were made by membrane cracking fibers.
The polypropylene high strength fibre melt spinning is: 1 single-headed pitch screw extruder, in order to adapt to the high viscosity of the fibropase, the fluidity is characterized, the screw compression is large, the smaller is 2.8, meter The section is as short as possible, the screw has a long diameter ratio ranges from 20 to 26. 2 Due to the large molecular weight, the melt temperature is simple to mellow to 130 ° C during spinning, and a method of adding a molecular weight regulator can also be used to reduce the spinning temperature. 3 The crystallization speed is faster during the cooling process, and the cooling temperature should be slightly lower.
The polypropylene high strength fibre has been treated with short-range textile or tightening texture, i.e., the cooling process is short, and the ramp can be 1m or less. For example, the annual production of 1 kt short fiber production line, from spinning, stretching, constitutive, curling to cutting, can be placed in a factory with high 8m, 30m long, with less investment, high efficiency, cost reduction.
Application range of polypropylene high strength fibre: polypropylene high strength fibre is widely used in safety net, seat belt, safety rope, industrial suspender, industrial cloth, cable, container bag, anti-cracking engineering fiber, high pressure fire water belt, conveyor belt, industry Sewing thread, polypropylene anti-cracking fiber, etc.
Use polypropylene high strength fibre weaving, suitable for roads, railways, airports, seawall, water channels, reservoirs, harbor and bridges, have no need to break saving, building a dam, damping, fast, high indecisive, investment Provincial, quality and other advantages. Using polypropylene high-strength wire resistance, resistance, high strength, no water, light, stability, filter peeling, etc. Work, food, environmental protection and other industries.
Jiangyin Jinmeng Textile Co., Ltd. is a professional manufacturer specializing in the high-strength polypropylene industrial silk, engineering fiber, polypropylene high strength wire, woven geotextile and apropular radio, located in the south to Taihubei, Jiangyin Yunting Industrial area, traffic is very convenient.
