Embodiment 1

[0023] Such as figure 1 , 2 , shown in 3, a kind of rope-forming method of polyimide fiber twisted rope, manufacturing process is as follows:

[0024] 1) Use 8 bundles of polyimide filaments 1 with a specification of 1000 denier to perform parallel twisting to form a rope yarn 2 with a twist of 50 twists / m and a reverse twist in the twist direction;

[0025] 2) Twisting the three rope yarns 2 described in step 1) into sub-strands 3, the twist is 65 twists / m, and the twist direction is positive twist;

[0026] 3) Arranging the sub-strands 3 in step 2) in a double-layer sheath-core structure, and then twisting them into rope strands 4 with a twist degree of 60 twists / m and a reverse twist direction;

[0027] 4) The three rope strands 4 in step 3) are twisted into a twisted rope body 5, the twist degree is 50 twists / m, and the twist direction is positive twist.

Embodiment 2

[0029] Such as figure 1 , 2 , shown in 3, a kind of rope-forming method of polyimide twisted rope, manufacturing process is as follows:

[0030] 1) Use 6 bundles of polyimide filaments 1 with a specification of 1000 denier to perform parallel twisting to form a rope yarn 2 with a twist of 80 twists / m and a reverse twist in the twist direction;

[0031] 2) Twisting the three rope yarns 2 described in step 1) into sub-strands 3, the twist is 90 twists / m, and the twist direction is positive twist;

[0032] 3) Arranging the sub-strands 3 in step 2) in a double-layer sheath-core structure, and then twisting them into a rope strand 4 with a twist degree of 50 twists / m and a reverse twist direction;

[0033] 4) The three rope strands 4 in step 3) are twisted into a twisted rope body 5, the twist degree is 35 twists / m, and the twist direction is normal twist.

Embodiment 3

[0035] Such as figure 1 , 2 , shown in 3, a kind of rope-forming method of polyimide twisted rope, manufacturing process is as follows:

[0036] 1) Use 8 bundles of polyimide filaments 1 with a specification of 1000 denier to perform parallel twisting to form a rope yarn 2 with a twist of 80 twists / m and a positive twist in the twist direction;

[0037] 2) Twisting the three rope yarns 2 described in step 1) to form sub-strands 3 with a twist of 100 twists / m and reverse twist in the twist direction;

[0038] 3) Arranging the sub-strands 3 in step 2) in a double-layer sheath-core structure, and then twisting them into rope strands 4 with a twist degree of 50 twists / m and a positive twist direction;

[0039] 4) The three rope strands 4 in step 3) are twisted into a twisted rope body 5, the twist degree is 25 twists / m, and the twist direction is reverse twist.

Abstract

The invention discloses a producing method of a polyimide fiber stranded rope. 3 to 15 strands of polyimide filaments are combined and stranded into a rope yarn, at least three rope yarns are stranded into a sub strand, the sub strand is arrayed in a dual-layer manner to form a leather core structure and is stranded into a rope strand, and at least three rope strands form a stranded rope body. The producing method can utilize performances of polyimide fibers effectively, producing process is simple and reasonable, and the stranded rope has the advantages of high strength, fire proof and high-temperature resistance, radiation resistance and good insulation property.

Description

technical field [0001] The invention belongs to the technical field of ropes, in particular to a method for forming a polyimide fiber twisted rope. Background technique [0002] High-performance organic polymer fibers have developed rapidly in recent decades, and polyimide fibers have become one of the important varieties of high-tech fibers. With the improvement of polyimide synthesis technology, fiber spinning With the advancement of technology, the industrialization process of polyimide fibers with excellent comprehensive properties such as radiation resistance, high temperature resistance, and high strength has gradually accelerated, and it has played an increasingly important role in aerospace, national defense and military industries, new building materials, environmental protection, and fire protection. more important role. As a commonly used type of rope, twisted rope is widely used in various fields, but in the existing twisted rope, there are few applications of p...
