Polysulfonamide fiber compound rope and manufacturing method thereof

Abstract

The invention discloses a polysulfonamide fiber compound rope and a manufacturing method thereof. The polysulfonamide fiber compound rope comprises a rope surface and a rope core, wherein the rope surface is formed by weaving part of polysulfonamide fiber strands in the S twist direction and the other part of the polysulfonamide fiber strands in the Z twist direction, the rope core is arranged inside the rope surface, the rope surface is an outer sleeve formed by weaving the polysulfonamide fiber strands which are composed of a plurality of twisting polysulfonamide fiber filaments, the surfaces of the polysulfonamide fiber filaments are processed, and the rope core is an aggregate of polysulfonamide fiber filaments. The polysulfonamide fiber compound rope is woven compactly and has reasonable processing technologies, good heat resistance, good thermo-oxidative aging resistance and small thermal contraction.

Description

technical field

[0001] The invention belongs to the technical field of ropes, and in particular relates to a sulfonamide fiber core-spun rope and a preparation method thereof. Background technique

[0002] The core-spun rope is widely used due to its good properties of the inner and outer materials. Therefore, the core-spun rope is an important daily necessities. In the existing core-spun rope, although it has other high performance, However, the heat resistance and thermal oxygen aging resistance are poor, and the thermal shrinkage performance is relatively large. At present, the aramid fiber that can make up for these deficiencies has not been applied to the field of rope nets. Contents of the invention

[0003] The object of the present invention is to provide a polysulfonamide fiber core-spun rope with good heat resistance, good thermo-oxidative aging resistance and small heat shrinkage and a preparation method thereof.

[0004] In order to achieve the above-mentione...

Embodiment Construction

[0013] figure 1 It is a schematic diagram of the polysulfone fiber core-spun rope of the present invention, and this embodiment is specifically described in conjunction with the accompanying drawings. The polysulfone fiber core-spun rope includes a rope sheath 1 and a rope core 2, the rope core 2 is arranged in the rope sheath 1, and the rope The skin 1 is configured as an outer body woven from multiple bundles of sulfonamide fiber strands twisted from a plurality of surface-treated sulfonamide fiber filaments. The rope sheath 1 is a cylinder braided according to the S twist direction of part of the sulfonamide fiber strands and the Z twist direction of the other part of the sulfone fiber strands, and the rope core 2 is set as an aggregate of sulfone fiber fibers. In this embodiment, the rope sheath 1 is set as a cylinder formed by weaving 16 bundles of sulfonamide fiber strands according to 8 strands in the S twist direction and 8 bundles in the Z twist direction.
