Abstract
The utility model discloses a high-strength high-modulus polyvinyl acetate (PVA) fiber based stranded rope and relates to the field of ropes. The high-strength high-modulus PVA fiber based stranded rope comprises a PVA fiber stranded rope body (5), wherein the PVA fiber stranded rope body (5) is formed by stranding at least three PVA fiber rope strands (4), each of the PVA fiber rope strands (4) is formed by stranding multiple PVA fiber sub yarns (3) which are of a core+skin structure and arranged in a double-layer mode, each of the PVA fiber sub yarns (3) is formed by stranding at least three PVA fiber rope yarns (2), and each of the PVA fiber rope yarns (2) is formed by stranding 4-12 PVA fiber filament yarns (1) in a doubling mode. The high-strength high-modulus PVA fiber based stranded rope is simple in structure, low in cost and long in service life, the stranding process is easy to operate, and the rope has the advantages of being high in strength, high in modulus, good in corrosion resistance and weather resistance and the like.
Description
Technical field
The utility model relates to rope field, a kind of high strength high modulus PVA fiber base torsade specifically.
Background technology
Torsade is widely used as a kind of rope, so torsade is a kind of important daily living article, in existing torsade, for the application of high-performance fiber seldom.High strength high modulus PVA fiber is compared with nylon, polyester, high tenacity staple fibre etc., has that intensity is high, modulus is large, ductility is low, impact strength is high, good weatherability, good water absorption, a feature such as acidproof, alkaline-resisting, is a kind of desirable rope making raw material.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides the torsade of a kind of high strength high modulus PVA fiber base, utilizes the physical characteristic of PVA fiber, makes torsade have high strength, high-modulus, the feature such as corrosion-resistant, good weatherability.
For achieving the above object, the technical scheme that the utility model adopts is:
The torsade of a kind of high strength high modulus PVA fiber base, comprise PVA fiber torsade body, described torsade body is formed by the PVA fiber rope strand twisting of at least 3 strands, described PVA fiber rope strand is formed by many PVA fiber burst twistings with core+skin structure dual layer arrangement, described PVA fiber strand is formed by least 3 PVA cordage yarn twistings, and described PVA cordage yarn is formed by 4-12 bundle PVA fiber filament doubling twisting.
The dual layer arrangement rule of described PVA fiber thigh is 0+3,0+4,0+5,1+6,2+8,3+9,4+10 or 5+11.
The utility model is simple in structure, and twisting process is easy to operate, and rope has the features such as high strength, high-modulus, corrosion-resistant, good weatherability, and cost is low, long service life.
Accompanying drawing explanation
Fig. 1 is the utility model rope yarn 2 structural representations;
Fig. 2 is the utility model rope strand 3 structural representations;
Fig. 3 is the utility model overall structure schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As Figure 1-3, this high strength high modulus PVA fiber base torsade, comprise PVA fiber torsade body 5, described torsade body 5 is formed by PVA fiber rope strand 4 twistings of at least 3 strands, described PVA fiber rope strand 4 is formed by many PVA fiber burst 3 twistings with core+skin structure dual layer arrangement, described PVA fiber thigh 3 is formed by least 3 PVA cordage yarn 2 twistings, and described PVA cordage yarn 2 is formed by 4-12 bundle PVA fiber filament 1 doubling twisting, adopts 10 PVA fiber filaments 1 in the present embodiment.
The dual layer arrangement rule of described PVA fiber thigh 3 is 0+3,0+4,0+5,1+6,2+8,3+9,4+10 or 5+11; In the present embodiment, adopt 0+5.
The utility model is that the PVA fiber filament 1 of some is become to rope yarn 2 through doubling twisting, then the yarn 2 of restricting adds and is twisted son thigh 3 through secondary, then count share thigh 3 and become rope strand 4 through two-for-one twister, last rope strand 4 becomes torsade body 5 through rope machine twisting, in whole process, the twisting of adjacent step is twisted with the fingers on the contrary, guarantees the high strength of torsade.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
