Abstract

The invention provides a method for dyeing cotton fabrics by a humulus scandens wood dye, which comprises the following steps of: a, preparing materials, namely collecting fresh plants, cleaning, cutting and drying in the air; b, preparing dye solution; c, preparing a pre-mordant; d, performing pre-mordant treatment on the cotton fabrics, namely putting the cotton fabrics into the pre-mordant, boiling and cooling at room temperature; and e, dyeing the cotton fabrics, namely putting the treated cotton fabrics into the dye solution, heating for a certain period of time, cooling to room temperature, washing, and drying in the air to obtain yellow cotton fabrics. The invention discloses a method for dyeing cotton fabrics by a humulus scandens wood dye. The natural plant is utilized as a coloring dye and has no toxic or side effect, a synthetic dye is saved, the printing and dyeing cost is reduced, and the method is a green printing and dyeing process worthy of promotion.

Description

technical field [0001] The invention relates to a printing and dyeing method for cotton fabrics, in particular to a method of using natural plants as dyes for printing and dyeing, which belongs to the field of printing and dyeing. Background technique [0002] In recent years, the world has been very concerned about the deterioration of environmental quality and the imbalance of ecological balance. Human beings are facing the most serious environmental crisis in history. Most of the environmental pollution is directly related to the pollution of industries and industrial products. Aromatic amines, as dye intermediates, have been listed as suspected carcinogens by government agencies in some countries, and benzylamine in benzidine has been identified as the most potent carcinogen to humans. According to the requirements of ecological textiles and since 118 dyes were banned, environmentally friendly dyes have become the focus of the development of the dye industry and the prin...
