Abstract

The invention discloses a preparation method of a liquid-state nano disperse dye modified by graphene and graphene derivatives. A disperse dye filter cake and the graphene or the graphene derivativesare mixed, wherein the graphene derivatives comprise a graphene oxide and a reduced graphene oxide; the mixture is ground to obtain the liquid-state nano disperse dye modified by the graphene and thegraphene derivatives. A high-temperature high-pressure one-bath dyeing method is adopted for dyeing a terylene fabric, and reduction of the graphene oxide can be achieved in the reduction cleaning process. The fabric is endowed with the color performance by the disperse dye and endowed with the functionality by the reduced graphene oxide, dyeing and finishing are completed through a one-step method, the fabric is endowed with the colors and functionality, the after-treatment technology is omitted, the reduction time of the reduced graphene oxide is shortened, and the liquid-state nano dispersedye has great application potential in the field of textiles.

Description

technical field [0001] The invention relates to a preparation method and application of a liquid nano-disperse dye modified by graphene and its derivatives, and belongs to the technical field of development of functional dye auxiliaries and functional textiles. Background technique [0002] With the development of science and technology and the requirements for environmental protection, functional additives and textiles have become the focus of research in the textile field in recent years. People's requirements for textiles are not only for aesthetics, but also for functionality, such as anti-ultraviolet, anti-static, etc. . Due to its structural characteristics, synthetic fibers are prone to static electricity, which affects comfort during wearing. Solving the static electricity of synthetic fibers is a necessary problem. [0003] At present, there are also studies on functional textiles in the market, most of which are finished through pre-treatment or post-finishing pro...
