A light storage elastic covered wire and its production method

Abstract

The invention provides an elastic covered wire with a light storage function and a production method thereof. The light storage elastic covered wire includes: a skin layer material and a core wire, and the skin layer material is coated on the outside of the core wire, wherein the skin layer The crystalline phase and the amorphous phase are phase-separated in at least part of the material; one or more of the skin layer material and the core wire contains a light storage material. In the light-storing elastic covered wire of the present invention, the crystalline phase and the amorphous phase of the cortex material are separated, and the radial contraction of the cortex and the combination of the axial contraction (that is, radial expansion) of the core wire are realized, and the cortex and the core wire are tightly packed. Combined, the strength, bending resistance, scratch resistance and elastic recovery rate are improved, and the rebound rate of stretching, bending and compression exceeds 99%; when stretching, bending and extrusion, the core wire and the cortex are not easy peel off. The light storage material is distributed in the skin material or the core wire to achieve the effect of light absorption-light storage-luminescence, and is washable, anti-oxidation, luminous efficiency and light intensity are good.

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...

AI Technical Summary

Problems solved by technology

The development of light storage coated fabric is rapid, but it is easy to fall off after washing, the luminous performance declines, and the service life is short

There have been related reports on the development of light-storing fibers and yarns. Generally, polymer nanofibers and inorganic nanofibers doped with rare earths and other light-storing properties are used. Oxidation, light absorption and luminous efficiency are weak, which greatly limits its market development
