Method for dyeing of cotton fiber fabric with lonicera caerulea

Abstract

The invention discloses a method for dyeing of cotton fiber fabric with lonicera caerulea. The method includes the steps of: firstly making lonicera caerulea into a lonicera caerulea slurry; then subjecting the lonicera caerulea slurry to first filtering, adding filter residue A into anhydrous ethanol to perform extraction, then conducting second filtering and collecting a filtrate B; mixing filtrate A with anhydrous ethanol to obtain a mixed solution, subjecting the mixed solution to heating and uniform mixing, then performing standing for 8-24h, and subjecting the mixed solution to third filtering and then collecting filtrate C; mixing the filtrate B with the filtrate C and conducting evaporation to dryness, collecting the evaporated mixture, dissolving the mixture to make a dye concentrated solution; adding the dye concentrated solution into water to perform dilution, then putting cotton fiber fabric into the dye solution, carrying out dyeing, soaping, washing and release from a jar. The fabric made by the method provided by the invention has bright color, is safe and nontoxic, and has special fruit fragrance. Wearing of the clothes made from the fabric can avoid the harm caused by synthetic dyes to the human body.

Description

technical field [0001] The invention relates to a method for dyeing cotton fiber cloth with indigo fruit, belonging to the technical field of printing and dyeing. Background technique [0002] The raw materials of synthetic dyes commonly used in the printing and dyeing industry are aromatic hydrocarbon chemical products, so most of the synthetic dyes have varying degrees of impact and harm on the human body. These products can decompose more than 20 kinds of carcinogenic or allergic substances during the production process. The banned azo compounds can dissociate heavy metals such as lead (Pb), chromium (Cr), cadmium (Cd), cobalt (Co), copper (Cu), nickel (Ni) and mercury (Hg) under certain conditions ion. Even the synthetic dyes currently allowed to be used are not necessarily safe dyes, which more or less have certain effects and hazards on the human body, especially children's clothing and intimate textiles. At this stage, the so-called environmentally friendly syntheti...

Blue indigo fruit is a perennial shrub that grows in wet grasslands, forests or near mountain streams. It is a pure natural, pollution-free high-quality wild fruit. It is one of the unique plants in East Asia. Its stems, leaves and fruits also contain a large number of genus flowers. The purple-red pigment of cyanine pigments, indigo carmine, is bright in color, good in coloring, high in safety, and has a special fruity aroma. It is easily soluble in water and ethanol. If it can be fully extracted, it can be used as an excellent Vegetable dyes and blue berry dyes have been used as food dyes, but have not been reported as textile dyes
