Abstract

The invention provides a reversible thermochromic fabric, and relates to the technical field of functional fabrics; the reversible thermochromic fabric is composed of a basic fabric and a functional coating layer, wherein the functional coating layer includes the following substances in parts by weight: 50-60 parts of a high-molecular polymer emulsion, 30-40 parts of crystal violet lactone microcapsules, 10-15 parts of a discoloring additive, 5-8 parts of a fluorocarbon surfactant, 3-8 parts of a crosslinking agent, 3-5 parts of a penetrating agent, and 3-8 parts of silica. The reversible thermochromic fabric can show different colors at different temperatures, is beautiful and fashionable, also is used as a sensor, can help people perceive changes of the environment in time, and has the advantages of simple preparation method, stable performance and long service life.

Description

technical field [0001] The invention relates to the technical field of functional fabrics, in particular to a reversible thermochromic fabric. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's aesthetics have also changed, and they show different needs from traditional ones in clothing, food, housing, transportation and other aspects. The emergence of color-changing textiles meets people's individual needs. With the help of modern high-tech, the color or pattern of textiles shows a change from conventional "static" changes with changes in light, temperature, and dryness. For the looming "dynamic" effect. Since this color change is caused by the fabric being "automatically" changed by external stimuli, it is called an intelligent color-changing textile. The manufacturing technology of color-changing materials mainly includes two kinds of color-changing fibers and color-changing dyes. The ...
