Abstract

The invention discloses a coating size composition for a thermosensitive discoloring and energy storing textile and a coating preparation method. The coating size composition comprises the following components in parts by weight: 100 parts of waterborne polyurethane or polyacrylate adhesive and associative polyurethane thickener or polyacrylic acid synthetic thickener for adjusting viscosity, and 5 to 50 parts of thermosensitive discoloring and energy storing microcapsule powder. The coating preparation method comprises that the thermosensitive discoloring and energy storing microcapsule powder is used as a raw material, the waterborne polyurethane or polyacrylate adhesive is used as a coating finishing agent, and the thicker is adopted to adjust the viscosity, so that the coating size can be prepared; and then the coating size is uniformly coated on the surface of the textile in a way of direct blade coating, and the textile is subject to pre-baking and baking processes so as to obtain the thermosensitive discoloring and energy storing textile. The prepared textile has dual functions of thermosensitive discoloring and energy storing, thus having relatively wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of functional textiles, and in particular relates to a coating slurry composition for functional textiles with dual responsiveness to ambient temperature and a coating preparation method. The textiles can change color as the external ambient temperature changes. Reversible changes, and endothermic and exothermic reactions can also occur when the temperature changes, so as to achieve the purpose of adjusting the temperature. Background technique [0002] With the development of science and technology and the improvement of people's living standards, great changes have taken place in people's aesthetics, so they show different needs from traditional ones in clothing, food, housing, transportation and other aspects. People not only pursue the comfort and aesthetic features of traditional clothing, but also hope that the clothing itself can endow it with distinctive functions and characteristics, thus promoting ...
