The cable made of polypropylene high-strength wire and the net used in construction, transportation, agriculture, fishery and sports activities have high breaking strength, wear resistance, corrosion resistance, light weight and safety.
Polypropylene wire made of polypropylene high-strength wire, because of its low price, high strength, aging resistance, wear resistance, seawater corrosion resistance, good elasticity and other characteristics, Mainly used in woven bag sewing, football, volleyball, baseball, yo-yo lines, cable lines, nets, shoes material line, with lines bags line, kite line, ground line, the waste line, bags, sewing thread, lines to bundle of money, the curtain line, construction, engineering, line belt, line, toy lines, rope lines, optical cable around the line, line of fishing nets, and other industries.
What influences the strength factor ofpolypropylene high-strength wire?
1. The influence of melting index
The melting index of the raw material indicates the molecular weight of the raw material to a certain extent, and the fiber content increases under the same process conditions. If the molecular entanglement degree is high, the strength of the stretched fiber increases with the increase of molecular weight, and the molecular chain slippage is easy to occur when the molecular weight is low, which is manifested in the decrease of fiber strength. Several raw materials with different melting indices are used in the spinning process of polypropylene high strength wire.
In the trial spinning process, it is found that under the same technological conditions, the strength of the finished silk varies with the melting index of the raw material, and shows a certain regularity.
Under the same spinning temperature, the same number of stretching times and the same process parameters, the lower the melting index of polypropylene slices, the higher the strength of polypropylene high-strength filaments.
2. The influence of stretch factor
The stretching process of fiber is destroyed the original structure of fiber morphology, generate a new sequence state structure, under the action of tensile stress and the thermal effect, increase the activity of the macromolecular chain segment, any structural unit gathered the fiber axial orientation, rearrange, adding new combining site, the more molecular chain in a particularly good stress in the fiber under state, The fiber density increases with the increase of the stretch ratio.
The strength of the fiber increases with the increase of the stretch factor, and the contribution of the stretch factor to the fiber strength is greater.
Xuzhou Heping Chemical Fiber Co., Ltd. is located in Xuzhou, Jiangsu.
