Embodiment 1
[0029] Printing method of silk fabric
[0030] (1) Add the silk power textile to the pretreatment bath containing 0.8g / L alum, 0.5g / L nonionic surfactant AEO9, 1.0g / L sodium pyrrolidone carboxylate, adjust pH=5, control the bath ratio The ratio is 1:50, and the temperature is raised to 60°C for 45 minutes of pretreatment. After the end, the silk electric textile fabric is taken out, dehydrated, and dried at 80-100°C to obtain a pretreated silk electric textile fabric.
[0031] (2) Add the natural dye chestnut shell pigment into tetraethylene glycol and nonionic surfactant AEO3, mix well, then dissolve with a small amount of deionized water to make a natural dye solution; use a small amount of citric acid and tannic acid respectively Dissolve in water to make citric acid solution and tannic acid solution; add the 8% guar collagen paste with solid content into the enamel beaker, add the natural dye solution and the citric acid solution respectively under stirring, and finally ad...
