Problems solved by technology

Wigs are generally divided into animal keratin fiber hair and synthetic wigs. Animal keratin wigs generally include human hair, horsetail, horse mane, yak hair, oxtail, etc. Animal keratin wigs are better in simulation, but the production of animal keratin fibers is low. The price is high and the growth cycle is long, which is far from meeting the large demand of the market; synthetic polymers are cheap and easy to process. In addition to the general superior properties of chemical fibers, such as high strength, light weight, easy to wash and dry, and good elasticity , Not afraid of mildew and moth, etc., it b

Abstract

The invention belongs to the field of functional fiber materials and discloses a luminous color-changing monofilament and a preparation method thereof. The preparation method includes: melting a polymer matrix raw material, and adding an additive identical with the polymer matrix raw material in refraction coefficient; melting, blending and extruding in a melt extruder, performing cooling, stretching, thermosetting and winding to obtain a color-changing fiber monofilament, and thermally fitting one end of the color-changing fiber monofilament onto an LED lamp strip to obtain the luminous color-changing monofilament. With the help of the additive identical with the polymer matrix raw material in refraction coefficient, the monofilament has good light transmission performance; by changing a fiber end light source and color thereof, monofilaments different in color and having brightness are obtained. The monofilament can be used for doll hair, human hairpieces, woven luminous color-developing fabric, warning boards and photoconduction induction control sensing units.

Description

Technical field [0001] The invention belongs to the field of functional fiber materials, and specifically relates to a luminous color-changing monofilament and a preparation method thereof. Background technique [0002] Color-changing fiber is one of a wide variety of new clothing materials. Its appearance is mainly due to modern high-tech, so that the color or pattern of textiles will show up with changes in light, temperature, and humidity. Different effects. Color-changing fibers were first used in 1970. On the battlefield of the Vietnam War, CYANAMIDE of the United States developed a fabric that can absorb light and change its color in order to meet the functional requirements of better concealment and camouflage during combat. . Since then, various color-changing materials such as embroidery velvet, knitting yarn, and woven yarn have emerged. It has gradually been widely used in sweaters, sports shoes, hats, stockings, decorative leather and various clothing and apparel. ...
