Embodiment 2

[0028] Embodiment 2: This embodiment is improved on the basis of Embodiment 1. Others remain the same, only a number of fixed blocks 10 are set on the surface of the further described reflective column 3, and each of the fixed blocks 10 is connected with The reflective column 3 is integrally formed, and each of the fixing blocks 10 is inserted into the transparent layer. Each of the fixing blocks 10 can be needle-shaped, cylindrical, or other shapes. Several protrusions 11 are provided on the surface of 10, and each protrusion 11 is integrally formed with the fixing block 10, and each protrusion 11 is needle-shaped or cylindrical.

[0029] Furthermore, each of the reflective columns 3 is a cylindrical structure, and the adjacent reflective columns 3 are arranged perpendicular to each other, so that each of the reflective columns 3 can be more stable inside the light-transmitting layer 2, The reflective column 3 will not move in the light-transmitting layer 2 due to the weaving...

Embodiment 3

[0030]Embodiment 3: Embodiment 3 is an improvement carried out on the basis of Embodiment 2. The bottom layer 12 of the fabric is also provided on the light-transmitting layer 2. The bottom layer 12 of the fabric is made of nanofiber material to improve the light-transmitting layer. 2 and the friction between the base layer of the fabric, to avoid the smooth surface of the light-transmitting layer 2, which will not be well twisted with the base layer of the fabric during the weaving process and affect the performance of the fabric.

[0031] Furthermore, the surface of the light-transmitting layer 2 is provided with air-permeable micropores 13 to improve the overall air permeability of the fabric.

Abstract

The invention relates to the technical field of clothing fabrics, in particular to a color-changing fabric under sunlight, which includes a fabric base layer and a color-changing material layer. There is a cavity inside the column, and several through holes are opened on each of the reflective columns, and each of the through holes communicates with the corresponding cavity, and a number of inorganic light beams are also provided on the surface of each of the reflective columns. Each of the cavities is provided with photochromic microcapsules, each of the photochromic microcapsules is filled with an organic photochromic agent, and an antioxidant is added to the organic photochromic agent. Combined with organic photochromic, the organic photochromic agent is not directly exposed to sunlight, which prolongs the color life of photochromic fabrics, and the setting of the reflective layer improves the color changing experience and the visual effect is better.

Description

technical field [0001] The invention relates to the technical field of clothing fabrics, in particular to a fabric that changes color under sunlight. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's demand for textiles has gradually changed from practicality to diversity and functionality. Color-changing products can meet people's needs for functionality and diversity of textiles. [0003] Photochromic fabrics are made by adding photochromic substances inside or adhering to the surface of the fabric. The photochromic substances are used to absorb visible light and ultraviolet light under sunlight to change the color. When the light disappears, it will reversibly change back to the original. color, but the photochromic fabric prepared by the prior art has the defects of poor stability and short service life due to long-term direct exposure to sunlight. Contents of the invention [0004] ...
