Abstract

The invention provides a textile product printing and dyeing method including: subjecting natural fibers to ionic modification; adding aluminum salt or ferric salt modifiers when the water temperature in a dyeing vat is 45-55 DEG C, increasing the temperature to 70-90 DEG C and holding; dyeing the modified natural fibers; and adding natural dye when the water temperature in the dyeing vat is 40-60 DEG C, regulating the pH (potential of hydrogen) to 3-10, increasing the temperature to 70-99 DEG C and holding. Textile products printed and dyed by the textile product printing and dyeing method are environment-friendly and uniform in dyeing without fading.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a method for textile printing and dyeing. Background technique [0002] Textiles are essential daily necessities for human beings. The properties of dyes and other chemicals used in textile printing and dyeing directly affect people's health and social development. With the rapid development of the textile industry, a large number of dyes with bright color, high color strength, excellent dyeing performance and good fastness have been continuously developed. At the same time, high-grade dyes such as vat dyes, reactive dyes, and disperse dyes have also been added. However, many intermediates in the production of these dyes are toxic. With the improvement of people's awareness of environmental protection, the pollution problems caused by synthetic dyes in the process of production and application have attracted more and more attention. People began to abandon synthetic dy...
