Abstract

The invention discloses a photochromic nylon fiber and a preparation method thereof. The photochromic nylon fiber is composed of the following components in parts by weight: 6-100 parts of nylon, 1-5 parts of photochromic material, and 1-10 parts of spinning auxiliary; the photochromic material is selected from phosphomolybdic acid isonicotinic acid, spiropyrane derivatives or azobenzenes. The photochromic nylon fiber disclosed by the invention has the beneficial effect that the obtained photochromic nylon fiber can become as yellow green from primary faint yellow under the effect of ultraviolet light; and the discoloring function cannot be lost along the time, the processing is simple and the industrial implementation is convenient; the photochromic nylon fiber has great application prospect in the fields of national defenses, civilian use and counterfeiting prevention.

Description

technical field [0001] The invention relates to a photochromic fiber and a preparation method thereof. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people put forward higher requirements for the color of clothing, not only need the appropriate color, but also hope that the color of the pattern can also change with the light, and for special fields, For example, the clothing of the army also hopes to change with the intensity of sunlight; the color of the material also has special significance in the field of anti-counterfeiting. [0003] At present, many patents disclose their respective technologies, but most of the color-changing materials are formed by coating color-changing materials, such as inks and coatings, on the base material. Adopt this method, the life-span of discoloration material is shorter, when coating comes off, discoloration function also just loses thereupon, therefore, can...
