Abstract

The invention discloses a preparation method for a nanometer platinum viscose fiber. The preparation method comprises the following steps of: carrying out pre-processing: firstly, carrying out acid pickling on nanometer platinum micro-particles, and then, washing the nanometer platinum micro-particles by potassium hydroxide alkaline liquor until the platinum micro-particles are neutral; (2) carrying out surface processing: adding the nanometer platinum micro-particles into ethyl alcohol or water, carrying out ultrasonic dispersion, and then, adding a coupling agent; (3) compounding a loading system: evenly dispersing the nanometer platinum micro-particles subjected to the surface processing and an inert carrier in an ethyl alcohol and ethylene glycol mixed solution, carrying out ultrasonicdispersion, and under a high-speed stirring condition, loading the platinum micro-particles to the surface of the inert carrier by a microwave heating method to obtain the loaded platinum micro-particles; (4) blending the loaded nanometer platinum micro-particles and a viscose spinning solution, and carrying out spinning by a two-bath method, so as to obtain a mixed fiber; and (5) carrying out steam processing: processing the mixed fiber by steam for 10-30 min, then, carrying out high-pressure steaming for 10-20 min, and finally, carrying out drying.

Description

technical field [0001] The invention relates to a method for preparing a fabric in the field of home textiles, and in particular discloses a method for preparing a nano-platinum viscose fiber. Background technique [0002] With the development of social economy and science and technology, people's consumption concept and demand for various textile products are also constantly changing. They not only have requirements for the appearance and comfort of textiles, but also pay more and more attention to the functionality and environmental protection of fabric materials. etc., so various new fibers emerge as the times require. The viscose-based fiber not only has the natural comfort of cotton fiber, but also has the smoothness and coolness of silk, high moisture regain, good color fastness, and complete color spectrum, which is very suitable for clothing and home textile products. [0003] The raw material used for nano-platinum is platinum (platinum) metal, with a particle size...
