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, anti- Ultraviolet, light-shielding and low thermal conductivity.
However, there are still some difficulties in the processing of nano-carbon black in the printing paste. In addition to the easy agglomeration of nano-carbon black, the direct or weak combination with the fiber matrix leads to poor color fastness to rubbing, which seriously affects its process application.
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.
