Problems solved by technology

[0005] Conductive fiber is a kind of conductive fiber invented earlier. There are two main methods for preparing conductive fiber by using inorganic conductive nanoparticles. The first type is the blending method of conductive particles and polymers, and the second type is conductive polymer adsorption. Conductive particle method, however, the obtained conductive fibers still need to be further improved in terms of conductive heat generation, resistance, strength and color fastness

Description

technical field [0001] The invention relates to the field of water-based carbon nanotube dyes, in particular to a dye composition and a preparation method thereof, a conductive heating fiber and a preparation method thereof, and a conductive heating fabric. Background technique [0002] Disperse dyes are a class of hydrophobic non-ionic dyes, usually with small molecular weight and simple structure, and can be in a uniformly dispersed state when interacting with dispersants in aqueous solution. Dye molecules can enter the interior of the fiber and dye through the interaction of hydrogen bonds, van der Waals forces and fibers. [0003] Carbon nanotubes are seamless nanotubes rolled from single-layer or multi-layer graphite sheets. Due to their unique structure and nano-effects, carbon nanotubes exhibit excellent mechanical properties and good thermal and electrical conductivity. [0004] Graphene is a carbon atom with sp 2 The honeycomb planar film formed by the hybrid meth...
