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...

Abstract

The invention discloses a natural dye ecological printing method for a protein fiber fabric. The method comprises the following steps that the protein fiber fabric is pretreated, wherein natural dye is added into tetraglycol and a nonionic surfactant AEO3, the materials are mixed to be uniform and dissolved with a little amount of deionized water, and a natural dye solution is prepared; citric acid and tannic acid are dissolved with a little amount of water separately to prepare a citric acid solution and a tannic acid solution; printing raw paste is added into an enamel beaker, the natural dye solution and the citric acid solution are added into the enamel beaker separately under stirring, the tannic acid solution is lastly added, the solutions are stirred to be uniform, and printing color paste is prepared; the pretreated protein fiber fabric is processed through the printing color paste according to a conventional printing technology. According to the method, a fabric printing method taking urea as an additive is not adopted, and influences on the environment are reduced and the whole printing processing ecological property is improved while it is guaranteed that a good printing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to an ecological printing method for protein fiber fabrics with natural dyes. Background technique [0002] When textile fabrics are used in clothing and home textile products, in order to obtain bright colors and rich patterns, different dyes must be used for dyeing or printing. The development of synthetic dyes has brought us convenient and fast printing and dyeing processing technology and a colorful world. However, the high chemical stability and low biodegradability of synthetic dyes increase the difficulty of printing and dyeing wastewater treatment and aggravate the pollution of the ecological environment. The harm of synthetic dyes to the human body has also become increasingly prominent. Natural dyes have good compatibility with the environment, are biodegradable, non-toxic and harmless, non-allergic and carcinogenic to the skin, meet the ecological requi...
