Method for serging shuttleless sleeve band for heavy parachute rope

Abstract

The invention discloses a method for serging a shuttleless sleeve band for a heavy parachute rope. The method comprises the steps as follows: selecting low-melting-point synthetic fiber multifilaments with the same characteristics as serging lines based on the original weft yarns and the serging lines; combining and twisting the low melting point synthetic fiber multifilaments with the original serging lines to serve as the serging lines; leading serging twisted yarns with hot melt fibers into the edge of a tubular sleeve band fabric by cooperation of a weft insertion needle and a serging bearded needle of a shuttleless ribbon loom to form knitted serging; and after finishing the serging operation, hotly shaping low-melting-point thermal links, controlling the shaping temperature for bonding the fibers with one part of the warp yarns, the weft yarns and the serging lines at selvedges, and cooling and shaping at a normal temperature for enabling the other part of the warp yarns, the weft yarns and the serging lines outside the selvedges to form bonding points under the action of the thermal links. According to the method, the low-melting-point thermal links with the similar characteristics are combined into a serging structure of a weaving system, so that the wear resistance and the stability of the knitted selvedges are improved and the problem of continuous weft sloughing caused by breakage of local serging lines due to larger load on the fabric or selvedge hooking is solved.

Description

technical field [0001] The invention relates to a method for overlocking the parachute of a heavy parachute. Background technique [0002] The parachute is an aerodynamic braking system, and the parachute is an important part of the system, while the heavy-duty parachute uses a woven narrow tubular sleeve as the parachute to ensure that the system meets the aerodynamic braking requirements of balanced high-speed and heavy loads. With the continuous development of science and technology, parachute has developed into an independent system as a kind of air-stabilized reducer. Parachutes have a wide range of uses and many types, and their classifications are also different. According to the purpose and characteristics of parachutes, it can be summarized into four categories: human parachutes for people returning to the ground from the air, such as various parachute parachutes, lifesaving umbrellas, sports umbrellas, etc.; Umbrellas, aerial bomb umbrellas, etc.; aircraft umbrel...

Problems solved by technology

[0004] In order to overcome the performance defect of the unstable belt edge structure of the shuttleless loom belt machine sleeve, the task of the present invention is to provide a parachute cord shuttleless sleeve with stable and reliable belt edge structure, high wear resistance, creep resistance, and no deformation. The edge-locking method of the belt is used to solve the problem of continuous weft detachment caused by the decoupling of the fabric pulled by the shuttleless belt for the parachute parachute
