preparation example Construction

[0022] The preparation method of this escape rope is realized through the following steps:

[0023] (1) Select raw materials: select high-strength polyester fiber filaments with a specification of 1000D;

[0024] (2) Initial twist: 3 high-strength polyester fiber filaments are combined into one strand, with a twist of 120-160 twists / m; 10 high-strength polyester fiber filaments with a specification of 1000D are combined into one strand, with a twist of 80-120 twist / m;

[0025] (3), re-twisting: take three strands of high-strength polyester fiber strands after primary twisting for re-twisting, and the twist is 50-70 twists / m;

[0026] (4) Pre-weaving: 3 high-strength polyester fiber strands twisted by the twisting machine are pre-woven on the automatic pre-looming machine into bobbins that meet the spindle size of the high-speed weaving machine for weaving;

[0027] (5) Rope: The aggregate of 10 high-strength polyester fiber three-strand twisted yarns is the rope core 2, and ...

Abstract

The invention discloses an escape rope and a preparation method thereof and relates to the field of woven ropes. The escape rope comprises a rope skin (1) and a rope core (2), wherein the rope skin (1) sleeves the exterior of the rope core (2) so as to be combined and woven to form the rope, the rope skin (1) is a jacket body which is formed by twisting and pre-weaving a high-strength polyester fiber filament, a plied yarn of the high-strength polyester fiber for pre-weaving the rope skin (1) is formed by twisting three high-strength polyester fiber filaments, the rope core (2) is prepared by twisting three high-strength polyester fiber filaments, and ten high-strength polyester fiber filaments for twisting the rope core (2) are arranged. By adopting the high-strength polyester fiber filaments for preparing the rope skin and the rope core, the rope skin and the rope core are combined and woven integrally to form the rope which is compact in structure. By means of characteristics of the high-strength polyester fibers, the rope has the characteristics of being light in weight, low in ductility, high in strength and good in safety performance and is widely applied to the fields of fire safety, fire rescue, building escape, mining escape and the like.

Description

technical field [0001] The invention relates to the field of braided ropes, in particular to an escape rope and a preparation method thereof. Background technique [0002] Escape rope is an important daily necessities, and it is also an essential product for fire safety, fire rescue, construction escape, and mining escape. It has very high requirements for the quality, ductility, strength and safety performance of the rope. The rope on the rope cannot meet the performance requirements of the escape rope. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides an escape rope and its preparation method. High-strength polyester fiber filaments are used as raw materials to make the rope sheath and rope core, and the performance of the rope meets the requirements of the escape rope. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] An escape rope...
