Abstract

The invention relates to a method for dyeing cellulose fiber fabric by using suaeda salsa natural dye, and the method comprises the following processes: 1) a modification process of the cellulose fiber fabric: placing the cellulose fiber fabric into a solution containing 4-8% (o.w.f) (on weight of fabric) of cationic modifier and 4-6g / L of NaOH modifier at a bath ratio of 1:50, heating up to 70-90 DEG C at the heating-up speed of 2 DEG C / minute at room temperature, and performing reaction for 10-20 minutes; and modifying, washing the fabric with hot water, washing with cold water, carrying out acid washing, washing with cold water and drying; and 2) a dyeing process: using a direct dyeing method to dye the cellulose fiber fabric after the modification, washing with water, soaping, washing with water, and drying in the shade. The cellulose fiber fabric dyed by the method is natural and elegant in color and luster, and has the advantages of good washing fastness and rubbing fastness, suitability for industrial production, no toxicity, no harmless and no pollution free and good application prospects.

Description

technical field [0001] The present invention relates to a method for applying the dyeing extract of the plant itself on textiles, in particular to a method for dyeing cellulose fiber fabrics with Suaeda salsa natural dyes. Background technique [0002] In recent years, due to the influence of environmental problems and energy problems, people tend to pursue sustainable, environmentally friendly and beneficial methods to prepare dyes. The development of natural dyes is the general trend of the development of applied dyes in the world. Natural dyes refer to dyes obtained from plants, animals or mineral resources with little or no chemical processing. Many natural dyes are safe, reliable, natural in color, and close to natural substances. And other advantages, natural, multi-functional is the development trend of dyes. [0003] Salsa salsa (Suaeda salsa), the young seedlings are called "wolf's tail strips", often called "haiyingcai", "alkali", "saltworm", annual herb, stems ar...
