Light-storage elastic covered wire and production method thereof

Abstract

The invention provides an elastic covered wire with a light storage function and a production method thereof. The light-storage elastic covered wire comprises a sheath layer material and a core wire,wherein the sheath layer material covers the core wire, and a crystal phase and an amorphous phase in at least a part of region of the sheath layer material are subjected to phase separation ; one ormore of the sheath layer material and the core wire contain a light storage material. According to the light-storage elastic covered wire, the crystal phase and the amorphous phase of the sheath layermaterial are in phase separation, so that the radial contraction of the sheath layer is realized, the radial contraction (namely radial expansion) of the sheath layer is combined with the axial contraction (namely radial expansion) of the core wire, and the sheath layer is tightly combined with the core wire, so that the strength, the bending resistance, the scratch resistance and the abrasion resistance as well as the elasticity recovery rate are improved, and the elasticity recovery rate of stretching, bending and compression exceeds 99%; during stretching, bending and extruding, the core wire and the sheath layer are not prone to stripping. The light storage material is distributed in the sheath material or the core wire to achieve the effects of absorbing, storing and emitting light and has good washing resistance, oxidation resistance, luminous efficiency and light intensity.

Description

technical field

[0001] The invention relates to a fiber and a production method thereof, in particular to a light storage elastic covered wire and a production method thereof. Background technique

[0002] Higher strength filaments or yarns are the first choice for many shoes, outdoor products, backpacks, etc.; usually filaments or yarns are multifilaments composed of many tiny monofilaments, which are easy to snag during use , Not wear-resistant, not waterproof and other shortcomings. The current solution is usually to dip, coat or coat the textiles, but after the treatment, the gaps between the unique fibers of the textiles are covered, sacrificing the air permeability, softness, luster, texture, etc. of the textiles, and The shrinkage difference between the coating and the fabric often affects its usability, fit, etc. If the multifilament is replaced by monofilament of the same thickness, although the problem of snagging can be solved, the monofilament has the defects o...
