Preparation method of fluorescent textile fiber with infrared radiation

Abstract

The invention relates to preparation method of a fluorescent textile fiber with infrared radiation. The fluorescent textile fiber comprises an infrared radiation fluorescent material, a textile fiber material and an assistant material. The fluorescent textile fiber with infrared radiation is characterized by comprising 5-8wt% of the infrared radiation fluorescent material, 91-94wt% of the textile fiber material and 1wt% of the assistant material. The preparation method comprises the following steps: fully and uniformly mixing the infrared radiation fluorescent material, the textile fiber material and the assistant material; after melting at a high temperature, drawing to textile cellosilks which are 0.001-0.1mm in diameter, wherein the infrared radiation fluorescent textile cellosilks emit near infrared fluorescence which cannot be seen by human under excitation of a long-wave ultraviolet light source or a blue light source, and when the exciting light is stopped, infrared long afterglow continuously exists in over 100 hours; forming various fiber products with infrared radiation function through spinning and weaving processes and the like. The fiber products such as wrist supports, socks, gloves, masks, waistbands and underwear have the functions of health-care and physiotherapy, signal identification at night, anti-counterfeit labels and the like.

Description

technical field [0001] The invention belongs to the field of preparation of textile fiber silk weaving materials. Background technique [0002] Most of the textile fiber materials and products with fluorescent effect now use visible light long afterglow luminescent materials, which are mixed with fibers to prepare luminescent textile fiber products with luminous effect, such as clothing, plush toys, etc., and the long afterglow luminescent materials used The material is a fluorescent material such as rare earth aluminate or zinc sulfide, which emits visible light under the excitation of ultraviolet light, and the afterglow can last for about 10 hours, as disclosed in Chinese patents 02156930, 201110407246, and 201210086916. [0003] Existing products with infrared radiation function are mostly produced by electrified heating, chemical reaction thermal effect, red laser irradiation, infrared lamps, and infrared spectrum instruments. They mainly produce near-infrared and far-i...
