Thermochromic yarn is an intelligent fiber that can change color with temperature. There have been studies and applications of thermochromic yarn in clothing, home furnishings and other fields at home and abroad, but the design and development of variable color striped knitted fabrics is still in the preliminary stage. The future development trend of the textile industry will pay more attention to green, intelligent and personalized. The research and development and application of new fiber materials, the innovative design of intelligent textiles, and the satisfaction of personalized needs will become the focus of industry attention. Functional knitted fabrics have now been widely used in various fields. In order to meet people's needs, the development and application market of new fibers is becoming more and more popular. Thermochromic fiber, as an intelligent material with unique optical properties, has attracted widespread attention in the field of textile science. Its uniqueness lies in the fact that its color can change visibly with the rise and fall of temperature, providing new possibilities for the design and functionality of textiles. In the field of textiles, the introduction of thermochromic fiber has brought new possibilities for clothing design, creating colorful fashion products that change at different temperatures.
