Light-storing polyvinyl chloride composite fiber for wig and preparation method

Abstract

The invention relates to a light-storing polyvinyl chloride composite fiber for a wig and a preparation method thereof. Polyvinyl chloride is adopted as a base material. The light-storing polyvinyl chloride composite fiber mainly comprises the following materials: Eu2<+> and Dy3<+> activated alkine earth silicate, which accounts for 5-20% of total weight of the composite fiber and of which the grain size, and 20 parts of chlorinated polyvinyl chloride added to 100 parts of polyvinyl chloride, wherein the grain size of Eu2<+> and Dy3<+> activated alkine earth silicate is 3-15 microns. The initial luminance is 700-1500mcd / m<2> after the composite fiber is excited for 10 minutes under the illuminance of 1000LX; the composite fiber is fed to a low-speed mixer after adopting sub-step charging and mixing steps, and is metered, melted, extruded, wound, drafted and subjected thermal treatment to be finally prepared into the composite fiber. By adopting the light-storing polyvinyl chloride composite fiber, the Eu2<+> and Dy3<+> activated alkine earth silicate is taken as a light-storing material; the light-storing polyvinyl chloride composite fiber is free of harm to a human body, uniform in light-storing material distribution, good in spinnability of light-storing fiber, high in initial luminance, and long in persistence; a person does not feel discomfort; the requirements for fabricating a wig product can be met by the physical properties.

Description

[technical field] [0001] The invention relates to a light-storage artificial filament and a preparation method thereof, in particular to a light-storage polyvinyl chloride composite fiber for wigs and a preparation method thereof. [Background technique] [0002] Wigs, as a necessary fashion element in life and a must-have consumer product for beauty makeup, have increasingly entered people's daily lives, and increasingly need differentiation and functionalization. The functional upgrade of wig products is fundamentally a Upgrading of wig raw materials. [0003] Polyvinyl chloride fiber is widely used in man-made fibers for hair decoration because of its excellent strength, curl retention and modification properties. Light-storing polyvinyl chloride fiber is a new type of functional fiber. By adding long The afterglow luminescent material has the novel performance of storing light energy and long-term automatic luminescence in the dark. The wig products made to a certain ext...

Problems solved by technology

[0004] Traditional light-storing fibers are mostly made by coating method, which has poor hand feeling, washing resistance and luminous effect, and the pollution to the environment is serious during use, which will cause damage to the human body

The skin-core composite spinning method has complex processes and equipment, resulting in high production costs, and there are problems with the fastness of the skin-core layer.

Fibers prepared by the blend spinning method have uneven luminescence due to uneven distribution of light-storing materials in the polymer.

Patent CN103184569A discloses a method for manufacturing light storage fibers. In this method, the light storage agent is added through a volumetric powder adding device, mixed with photopolymers, and then extruded by a screw to produce light storage fibers. However, the alkaline earth aluminum used as the light storage agent Salt has poor water resistance, poor chemical stability, and high requirements for raw material purity

Patent CN1107749C discloses a luminescent synthetic fiber and its preparation method. The method is to mix luminescent materials with mixed additives to make luminescent masterbatches and then blend and spin them with polymers. Because the granulation process is involved, the process and equipment are complicated and costly. Higher, and because the wig raw materials have higher requirements, the luminosity needs to be highly uniform, and the masterbatch spinning method is lacking in this aspect
