Abstract

The invention provides nanogold-based printing paste and application thereof in silk fabric. A preparation method of the silk fabric specifically includes: adding modified gold powder treated with alkaline liquid, nanogold sol, a carbon nanotube water solution, an imidazolidine-type surfactant and citric acid into polyacrylic paste, and grinding to form the nanogold-based printing paste; washing and air-drying the surface of the silk fabric, coating the surface with the nanogold-based printing paste, removing redundant paste to form a paste layer, laying gold foils on part of the fabric, performing hot rolling, thermally treating, and naturally cooling to obtain the silk fabric treated with the nanogold-based printing paste. The prepared printing paste contains nanogold and nanocarbon, so that thermal viscosity, film forming performance and stability of the paste are improved, adhesion of the gold foils is facilitated, and the silk fabric is endowed with multifunctionality.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a printing paste based on nano-gold and its application on silk fabrics. Background technique [0002] Since ancient times, textile printing technology has been closely related to human life, and traditional textile technology is closely related to ancient textile technology. Gold foil printing technology is a kind of traditional printing technology. The application of gold on textiles is initially to beat gold into gold leaf, and then directly stick it to the surface of the fabric, and the adhesive is also a simple natural substance such as protein, gelatin, and gum. However, with the continuous development of modern technology, gold foil printing technology has also made a qualitative leap. The raw materials have also changed from gold foil to gold powder, to copper-zinc alloy and aluminum instead of gold and silver powder, and the binder has also develope...
