New Type Intellectualized Clothing Materials - Color-changing Materials

摘要

This article mainly introduces the manufacture and application principle of photosensitive color-changing fiber and thermosensitive color-changing fiber in clothing color-changing materials so as to let people better understand them. People all have natural instincts to pursue niceness. All the colors in nature bring people nice enjoyment, which is what they earnestly yearn for and pursue. If clothing materials that constantly come into contact with people could be like "chameleon", changing color along with time, scene, temperature and even mood, it would bring much pleasure to people's life. Meanwhile, in some industry and field, color-changing materials also play the role of safety protection. This is not Arabian Nights. British scientific researchers have already developed color-changeable clothing. This type of clothing can change color at will. This type of clothing is also called liquid crystal fashionable dress, which belongs to the latest technological synthetic material. Liquid crystals that have been manufactured have reached over 3000 types, which all have fluidity of liquid and constitutive property of crystal. Therefore, once the crystal is influenced by external factors magnetism, electricity, sound, light, heat, force and etc, its molecular arrangement changes immediately, forming different colors. Experts mix two or three kinds different liquid crystals according to the demand of color change, and then spread them on textiles of different materials, a suit of fashionable dress that can change color is accomplished. There are two kinds of color-changing clothing developed in Britain. One is to change color along with time, which can change to many colors in one day. The other is to change color along with temperature. This kind of color-changing clothing adopts thermosensitive color-changing materials, which is to blend thermosensitive chemical compounds into dyestuff, and then print and dye on the fabric. Dyestuff is made of adhesive resinous microcapsules. Each capsule has liquid crystal that can appear different refractive index along with temperature change, so as to make the clothing v to many colors. Nowadays, scientists have already studied and mastered some technologies that subtly adjust thermosensitive color-changing materials, which make this kind of fabric bring out colorful effect under normal temperature environment. There is another luminous fabric that can store luminous energy, and then shine again in the darkness, which is especially suitable for staffs who work at night. Below is the introduction that focuses on photosensitive color-changing fiber and thermosensitive color-changing fiber.
