Embodiment 1

[0039] A color-changing clothing fabric is obtained by knitting and weaving a color-changing fiber, and the color-changing fiber is made by the following steps:

[0040] The first step is to prepare the following raw materials in parts by weight: 15 parts of polyvinyl alcohol, 6 parts of deionized water, 2 parts of carboxymethyl cellulose, 1 part of discoloration agent, 1 part of absolute ethanol and 1 part of self-cleaning filler;

[0041] In the second step, add polyvinyl alcohol and deionized water into the reaction kettle, control the reaction temperature at 90°C, and stir for 5 minutes at a speed of 300r / min. Dehydrated ethanol was added into the reaction kettle in turn, and the rotation speed was constant, and the stirring was continued for 10 hours, and after standing for 2 hours, the spinning solution was obtained;

[0042] The third step is to place the spinning solution obtained in the second step in the electrospinning device under the condition of avoiding light, t...

Embodiment 2

[0055] A color-changing clothing fabric is obtained by knitting and weaving a color-changing fiber, and the color-changing fiber is made by the following steps:

[0056] The first step is to prepare the following raw materials in parts by weight: 18 parts of polyvinyl alcohol, 7 parts of deionized water, 2 parts of carboxymethyl cellulose, 1 part of discoloration agent, 1 part of absolute ethanol and 1 part of self-cleaning filler;

[0057] In the second step, add polyvinyl alcohol and deionized water into the reaction kettle, control the reaction temperature at 92°C, and stir for 5 minutes at a speed of 400r / min. Dehydrated ethanol was added into the reaction kettle in turn, and the rotation speed was constant, and the stirring was continued for 11 hours, and after standing for 2.5 hours, the spinning solution was obtained;

[0058] The third step is to place the spinning solution obtained in the second step in the electrospinning device under the condition of avoiding light,...

Embodiment 3

[0071] A color-changing clothing fabric is obtained by knitting and weaving a color-changing fiber, and the color-changing fiber is made by the following steps:

[0072] The first step is to prepare the following raw materials in parts by weight: 20 parts of polyvinyl alcohol, 8 parts of deionized water, 3 parts of carboxymethyl cellulose, 1 part of discoloration agent, 1 part of absolute ethanol and 1 part of self-cleaning filler;

[0073] In the second step, add polyvinyl alcohol and deionized water into the reaction kettle, control the reaction temperature at 95°C, and stir for 5 minutes at a speed of 500r / min. Dehydrated ethanol was added into the reaction kettle in turn, the rotation speed was constant, and the stirring was continued for 12 hours, and after standing for 3 hours, the spinning solution was obtained;

[0074] The third step is to place the spinning solution obtained in the second step in the electrospinning device under the condition of avoiding light, the c...

Abstract

The invention discloses a color-changing garment fabric. The color-changing garment fabric is prepared from color-changing fibers through a knitting weaving method; the color-changing fibers are prepared from 15-20 parts of polyvinyl alcohol, 6-8 parts of deionized water, 2-3 parts of carboxymethyl cellulose, 1 part of color-changing agent, 1 part of absolute ethyl alcohol and 1 part of self-cleaning filler through electrostatic spinning, wherein the color-changing agent is subjected to a ring-closing reaction under ultraviolet irradiation, and the color changing agent becomes blue from a achromatic color, and is subjected to reversible ring-opening reaction under irradiation of visible light to recover the achromatic color, so that the fiber has the fantastic function of color changing; and the self-cleaning filler contains nano titanium dioxide and cuprous oxide, has the photocatalytic self-cleaning function and also has the antibacterial property, and therefore, the garment fabric prepared by the invention not only has a lasting color-changing function, but also has the characteristics of antibiosis, self-cleaning and good air permeability, and has huge utilization value in the preparation of color-changing clothing.

Description

technical field [0001] The invention belongs to the technical field of garment fabric preparation, and in particular relates to a color-changing garment fabric and a preparation method thereof. Background technique [0002] Color-changing clothing was first developed by the U.S. Department of Defense as an "invisibility cloak" for soldiers, which can change color with the surrounding environment. After the 1980s, color-changing clothing has been widely used in civilian fields. After entering the 21st century, the development of color-changing clothing has made greater progress. For example, Japan has studied a photochromic dye that can make synthetic fiber fabrics "dye" the color of the surrounding scenery and "melt" people's clothing into the natural scenery. Among them, British scientists processed liquid crystal material microcapsules into printable inks, coated on the surface of a black fiber, and displayed fascinating colors that changed rapidly with different body part...
