Background

The steel wire rope is a spiral steel wire bundle formed by twisting steel wires with mechanical property and geometric dimension meeting requirements together according to a certain rule, and comprises a rope core and strands. The steel wire rope plays the roles of lifting, traction, tensioning and bearing in the mechanical handling of materials, has high strength, light dead weight and stable and reliable work, and is widely applied to various industries such as machinery, mining, metallurgy and the like.

The wire rope core is one of the important components of the wire rope, plays a role in supporting in the radial direction and reducing the pressure among strands, can not only keep the stable physical structure of the wire rope, but also store lubricating grease, and releases part of the grease to lubricate among the wire rope strands when the wire rope is under pressure. The steel wire rope core comprises a fiber core and a metal material core, and the steel wire rope adopting the fiber core is flexible and has good flexibility; the steel wire rope adopting the steel core has high rigidity but relatively poor flexibility. In order to enable the steel wire rope to have high strength and flexibility, the fiber and the metal material are combined in a composite structure mode, and the steel wire rope has a good development prospect.

The fiber rope core of the steel wire rope in the market is mainly made of sisal, and the sisal rope core has the advantages of firm texture, good elasticity, friction resistance, corrosion resistance, good oil absorption and the like, and can play a better role in supporting, damping and oil storage in the steel wire rope. However, the sisal hemp is adopted to prepare the rope core of the steel wire rope, and the defects are that the sisal hemp has thicker fibers and uneven thickness of single fibers, and the problem of non-uniformity is easily caused during spinning, so that the diameter of the rope core fluctuates greatly along the length direction, and the service life of the steel wire rope is shortened. In addition, the global planting amount of the sisal is less and less, the sisal is limited by the yield and is used in large amount, the supply and demand of the sisal are short, and the price of the sisal is increased year by year. The jute fiber is shorter than sisal fiber, but the jute fiber is thinner and softer, has low price and can be used as a substitute of sisal, but the strength of the rope core prepared by the jute fiber is insufficient. If synthetic fibers are used in their entirety, there is a problem of insufficient lubrication inside the steel cord, and thus, an unexpected effect is obtained by properly combining natural fibers and synthetic fibers.
