Problems solved by technology

[0002] The stable and safe docking of large ships at the pier is inseparable from the credit of mooring ropes. At present, ropes made of polypropylene, polyester and polyamide fibers are mainly used as mooring ropes, but in actual use, there are many such mooring ropes. Problems, for example, although the specific gravity of polypropylene rope is smaller than that of water, it can float on the water surface, but polypropylene fiber is not resistant to ultraviolet rays, it is easy to age under sunlight, and has poor durability; polyester and polyamide ropes have a large specific gravity and will sink into It is not easy to find in the water, and it is easy to cause accidents caused by the rope being entangled with the propeller, and as the use time increases, mildew and biological adhesion will appear on the surface, which will affect further use

Abstract

A floating hollow polyester fiber mooring rope is a fiber rope made of hollow polyester fibers, wherein a plurality of through cavities distributed in the axial direction of the hollow polyester fibers are formed in each hollow polyester fiber, the through cavities are the same in shape and are symmetrically distributed with the center of the hollow polyester fiber as a symmetry axis, the hollow rate of the hollow polyester fibers ranges from 25% to 40%, the density of the hollow polyester fibers ranges from 0.95 g / cm<3> to 1.00 g / cm<3>, and the hollow polyester fibers are prepared from a polyester modified composite material. The polyester modified composite material is prepared from polyester slices, an ethylene-vinyl acetate copolymer, an antioxidant 1010, an auxiliary antioxidant DLTP and a nano silver-loaded cuprous oxide antibacterial agent, wherein the weight of the ethylene-vinyl acetate copolymer is 0.12-0.35% of the weight of the polyester slices, the weight of the antioxidant 1010 is 0.01-0.25% of the weight of polyester slices, the weight of the auxiliary antioxidant DLTP is 0.05-0.12% of the weight of the polyester slices, and the weight of the nano silver-loaded cuprous oxide antibacterial agent is 0.01-0.2% of the weight of the polyester slices.
