Abstract

The invention provides a preparation method for a mooring rope applied to a deep-sea buoy. The preparation method comprises the steps of a rope yarn preparation step, wherein a plurality of polyamidefiber multifilaments are subjected to twisting and doubling to form one rope yarn, a rope strand preparation step, wherein a plurality of rope yarns are subjected to doubling and twisting to form onerope strand, a rope preparation step, wherein a plurality of rope strands are subjected to weaving to form a rope, a heat setting step, wherein the rope is subjected to setting treatment in high-temperature steam at the temperature of 100 DEG C-140 DEG C for 1 h-8 h, and a pre-drafting step, wherein after the heat setting treatment, the rope is subjected to circular pulling force for drafting, andthe pulling value is 15%-35% of the breaking force. The mooring rope has the advantages that the mooring rope is applied to the deep sea operation, the stretching elongation rate is high, and the elastic recovery rate is high.

Description

technical field [0001] The present invention relates to the field of cables, and in particular, to mooring cables suitable for deep-sea buoys, their preparation methods and applications. Background technique [0002] In order to measure and collect data of the marine environment, observation buoys are widely used based on their long-term, continuous and unattended characteristics, and become the most important means of marine environment observation. [0003] The mooring system is an important part of the ocean observation buoy. The mooring system of the deep-sea mooring buoy is several kilometers deep. In order to control the weight of the system, the mooring system adopts a chain-cable hybrid structure, and the main body in the middle uses fiber cable. [0004] Deep-sea mooring buoys usually adopt the form of tension mooring, so the basic requirements for mooring cables are high strength and high ability to absorb wind and wave energy. The mooring cable has high strength...
