Abstract
The utility model relates to a polyamide wear-resistant stranded rope, which relates to textile ropes and is fine in wear-resistant property. The polyamide wear-resistant stranded rope is characterized in that a layer of polyamide is coated on the outer layer of the polyamide wear-resistant stranded rope. The wear-resistant stranded rope keeps original characteristics of a polyamide fiber rope, can be applied to occasions with high wear-resistant requirements, such as construction, cleaning and the like of buildings, is particularly adapted to ultra-high occasions needing ultra-long ropes to hoist constructors, and can avoid problems that strands of the rope are easy to be twisted and deformed and can not recover after usage.
Description
Technical field
The utility model belongs to the weaving rope.
Background technology
Because the service failure of polyamide (PA) fibrecord all is based on wearing and tearing, existing polyamide (PA) fibrecord is for improving anti-wear performance, obtain by the following method: adopt the twist factor method that the rope twist reduces rope that strengthens during manufacturing, this defective that reduces the twist factor method of rope is the fracture strength of having lost cord material significantly, can only be every meter weight method to increase rope wire density, thereby increased use cost and lost the many serviceabilities of rope, and the easy distortion of rope strand after rope uses can't be replied the risk that structural instability and distortion are scrapped ahead of time.
The utility model content
The problem that the utility model need solve provides the good polyamide abrasion-proof torsade of a kind of anti-wear performance.
The technical solution of the utility model adopts the polyamide torsade, it is characterized in that at the outer one deck polyurethane that coats of polyamide torsade.
Useful effect of the present utility model is: the polyurethane that anti-wear performance is good is coated on polyamide torsade skin, has improved the anti-wear performance of whole rope, and the every increase of polyurethane-coated thickness 1mm anti-wear performance just improves more than 50%; And the twist that can reduce rope when making increases the twist factor method of rope, and the twist factor advantage of this increase rope is the fracture strength that has increased substantially rope, and rope wire density has reduced 15%-25%, and fracture strength has improved 20%-30%; Thereby reduced use cost, increased the use occasion of rope, and eliminated thigh that rope uses the back rope risk that easily distortion can't be replied and distortion etc. is scrapped ahead of time.
The utility model is the compound wear-resisting torsade of a kind of polyamide fiber and polyurethane, and its advantage is that the product scope of application is wider; After rope coats polyurethane, can not influence original every function of use of polyamide fiber rope, and kept the original characteristic of polyamide fiber rope, can be applied to architecture construction and cleaning etc. and need wear-resisting demanding place, use superelevation and overlength occasion especially for lifting construction, can avoid thigh that rope uses the back rope easily distortion can't reply distortion and cause the risk of great personnel's economic loss that hanging basket and workmen fall.
Description of drawings
Accompanying drawing is represented polyamide fiber rope and polyurethane composite anti-wear torsade.
The specific embodiment
The utility model adopts solid wire density 3dtex-10dtex, multifilament threads density 200dtex-6000dtex polyamide 66 fiber; On yarn-twisting machine, twist with the fingers into 400dtex-50000dtex rope yarn; Adopt the rope yarn of line density 400dtex-50000dtex on the stranding machine of rope, to twist with the fingers into rope strand; Three, four, six strands of rope machines manufacture three, four with rope strand, six gangs of diameter 4mm-102mm, and line density (Mi Chong) 6Ktex-7500Ktex (g/m) twists with the fingers twisted rope 1 (seeing accompanying drawing); Coat the thick polyurethane of 1mm-5mm again at torsade skin 2 again.
Claims (2)
1. the polyamide torsade is adopted in polyamide abrasion-proof torsade, it is characterized in that at the outer one deck polyurethane that coats of polyamide torsade.
2. polyamide abrasion-proof torsade according to claim 1 is characterized in that the outer polyurethane 1mm-5mm that coats of polyamide torsade is thick.
