Nano-carbon black can be applied in polyester printing color paste, but many friends do not know how to apply it, and do not know where is the difficulty of adding nano-carbon black to polyester printing color paste. Introduce the role of nano carbon black in polyester printing.
Difficulties in the application of nano-carbon black in polyester printing
1. Liquid nano-carbon black needs to use a dispersant to solve the problem of poor dimensional stability that is easy to agglomerate. At the same time, the particle size, particle size and other components of carbon black greatly affect the color brightness and fastness of the fabric;
2. The compatibility of anionic/nonionic surfactants, liquid nano-carbon black and synthetic thickeners, to solve the viscosity increase or even gelation caused by the compatibility of liquid nano-carbon black and acrylic thickeners, and the flow of colorants Poor, difficult to print;
3. Nano-carbon black needs to be bonded to the fabric with adhesives and other additives, and it is difficult to unify the high color fastness and hand feeling of printed fabrics.
What role does nano carbon black play in polyester printing?
Nano carbon black has excellent blackness, high temperature resistance, and light resistance. Printed textiles made of nano carbon black have the functions of conducting electricity, removing static charge accumulation and preventing ultraviolet light. Nano carbon black printed fabrics have excellent antistatic properties, anti Ultraviolet, light-shielding and low thermal conductivity. However, there are still some difficulties in the processing of nano-carbon black in printing paste. In addition to the fact that nano-carbon black is prone to agglomeration, the direct or binding fastness to the fiber matrix is weak, resulting in poor color fastness to rubbing, which seriously affects its process application. .
