Under the action of light, heat and other physical or chemical factors, dyes that can reversibly change color are called color-changing dyes. Electrochromic materials); but the rubbing fastness and washing fastness of these dyes themselves are not ideal.
In the late 1990s, people introduced microcapsule technology into the preparation of color-changing dyes to make color-changing microcapsule materials. It can protect the color-changing material from the erosion of chemical substances, and at the same time improve the resistance and solvent resistance of the color-changing material to the external environment, and also improve the affinity of the color-changing material to the fiber, so as to better meet the requirements of textile finishing, processing and use. , so that the application of color-changing dyes in textiles has achieved a qualitative leap and improved performance.
Using color-changing microcapsule materials, textiles (fibers, yarns and fabrics or ready-to-wear garments, etc.) are processed by textile dyeing, printing/coating and post-finishing processes, so that they have color-changing properties; color-changing microcapsules are used for textile fabrics / Yarn dyeing and finishing processing, simple and stable operation, suitable for paint printing, coating finishing, dipping and padding processing, etc., and has a wide range of applicability; it is also suitable for plastic resin, ink and ceramic industries.
Compared with the color-changing microcapsule printing and dyeing technology, the microcapsule color-changing fiber technology has obvious advantages: the made color-changing fabric has good hand feeling, good washing resistance and long-lasting color-changing effect.
