Abstract
AbstractA kind of tungsten‐based polyvinyl alcohol (PVA) waterborne coating has been synthesized successfully. Two kinds of composite discoloration fabrics are prepared by cotton and polyester with coating method, which have a UV detection function. The color of composite discoloration fabric changes from white to blue under 365 nm UV lamp irradiation for 30 s and sunlight irradiation for 3 s. The influence of PVA concentration on the washability of fabric and the influence of polyurethane seal on discoloration of fabric are studied. In addition, the application of the water‐based coating shortens the preparation time of composite fabric, and greatly improves the preparation efficiency. This work lays a foundation for the development and application of photochromism textiles.
