Abstract

The invention provides a preparation method of a natural zephyranthes grandiflora capsule dye-stuff and application thereof. The preparation method comprises the following steps: washing, draining and then grinding zephyranthes grandiflora capsules into slurry; adding an organic solvent into the slurry, and then dipping the mixed slurry under a normal-temperature enclosed condition; and merging, filtering and then spray-drying the obtained impregnation liquid to obtain the natural zephyranthes grandiflora capsule dye-stuff. The application method of the natural zephyranthes grandiflora capsule dye-stuff comprises the following steps: firstly taking 10-20% of the natural zephyranthes grandiflora capsule dye-stuff and 2-10% of a mordant based on the mass of the dyed fabric; adding water to form dye liquor with the liquor ratio of 1:45-55; adjusting pH value of the dye liquor to 3-4; and finally placing the fabric fully moistened with hot water into the dye liquor for dyeing at the temperature of 60-80 DEG C for 30-60 minutes. The invention realizes waste utilization of the zephyranthes grandiflora capsules and improves dyeing effect and grade of fabrics, thus being especially applicable to dyeing silk fabrics and ensuring safe wearing of the fabrics; and the invention has the advantages of no any anaphylactic reaction, good ecological environment compatibility, biodegradability, rich raw materials and simple preparation process and simple dyeing process of the dye-stuff.

Description

technical field [0001] The invention relates to a preparation method and application of a natural dye, in particular to a preparation method and application of a natural dye from leek lotus capsules. Background technique [0002] At present, most of the dyes used in textile dyeing and finishing are synthetic dyes, and a large part of the raw materials and intermediates of these synthetic dyes are toxic substances. The research results show that there are more than 20 kinds of aromatic amines, more than 100 kinds Synthetic dyes may produce carcinogens, and more than 20 kinds of synthetic dyes are allergic to the skin, which not only seriously pollutes the environment, but also brings direct and indirect damage to the wearer or producer; and, due to the continuous consumption of petroleum resources, synthetic The problem of raw materials for dyes has also become increasingly tense. With the continuous enhancement of people's environmental protection and health awareness, trad...
