Description
Technical field
The present invention relates to Wire Rope Production technical fields more particularly to a kind of steel wire rope composite fiber core and preparation method thereof
With application.
Background technology
Currently, the material as elevator wire rope fibre core based on sisal hemp, restrict by part governor rope and balance in the market
Wire rope core select polyolefins synthetic fibers be made.Sisal Hemp Rope Core have solid quality, the good, rub resistance of elasticity, it is corrosion-resistant and
The advantages that oil absorption is good can play the role of preferably support, damping and oil storage in steel wire rope.But global sisal hemp
Plantation amount is fewer and fewer, is limited by sisal hemp yield and a large amount of uses of Sisal Hemp Rope Core, the price of sisal hemp go up year by year, compels
In cost pressure, each elevator ropes manufacturing enterprise is all in the substitute for finding Sisal Hemp Rope Core.
In fact, preparing wire rope core using sisal hemp, there is also some disadvantages, and relatively thick and single fiber the thickness of sisal fiber is not
, it causes to be difficult to control the uniformity when spinning, manufactured wire rope core diameter has larger fluctuation along its length, and then increases electricity
Vibration and noise of the terraced steel wire rope when elevator is run.And Huang harl is very short, fiber is thinner, more soft with respect to sisal hemp,
And price is relatively less expensive.
Invention content
The purpose of the present invention is to provide a kind of steel wire rope composite fiber cores and the preparation method and application thereof, using jute yarn
