Dyeing method of polyester fabric

The invention belongs to the technical field of fabrics, and particularly relates to a dyeing method of a polyester fabric, which comprises the following steps: cleaning a disperse dye, carrying out alkali treatment and trichloromethylsilane deposition, and hydrolyzing to form a hydroxylated disperse dye; the method comprises the following steps: roughening a polyester fabric, dip-dyeing the roughened polyester fabric in a dye solution containing a hydroxylated disperse dye for constant-temperature dip-dyeing and heating treatment, and finally cooling, washing and drying to obtain the dyed polyester fabric. According to the method, the defect of high-temperature and high-pressure dyeing of the polyester fabric is overcome, surface modification of the disperse dye is formed by utilizing the negative electricity adsorbability of the surface of the disperse dye and deposition of trichloromethylsilane, the connection stability of the disperse dye on the polyester fabric is improved, and the wear resistance of the disperse dye is also improved.

A nickel-copper-nickel-nickel tungsten multilayer plating layer and a preparation method thereof

The application discloses a nickel-copper-nickel-nickel tungsten multilayer plating layer and a preparation method thereof. After pretreatment of a base material, a nickel bottom layer is obtained by first electroplating nickel, a copper layer is obtained by electroplating copper, a nickel intermediate layer is obtained by second electroplating nickel, a nickel tungsten alloy surface layer is obtained by electroplating a nickel tungsten alloy, and then heat treatment is performed to obtain the nickel-copper-nickel-nickel tungsten multilayer plating layer. When electroplating the nickel tungsten alloy, a titanium base-iridium tantalum oxide coating anode is used, and the electroplating solution for electroplating the nickel tungsten alloy is a citric acid system. In the titanium base-iridium tantalum oxide coating anode, the mass fraction of tantalum is more than 5% higher than the mass fraction of iridium. The corrosion resistance of the plating layer is greatly improved through the cooperation of the multilayer plating layer and the improvement of the quality of the outermost plating layer.
