Problems solved by technology

[0004] In the existing field of plant dyeing, some plant dyes have been known and used by everyone, such as: rhubarb, tea, hematoxylin and pagoda japonica and other plant dyes have been applied in batches. As people's requirements for environmental protection and ecology become more and more Higher, the textile dyeing and finishing industry has already focused on the green production process. Therefore, it is extremely urgent to improve the color spectrum of plant dyes. Blue plays an important role in the color spectrum. At present, natural blue plant dyes are The most commonly used are isatidis and indigo. The active ingredient of isatidis is also called Daqingye. It is a vat dye made through a series of fermentation processes. It is not easy to control in the actual industrial production process; indigo can be used at this stage but It cannot be produced on a large scale; therefore, it is necessary to conduct in-depth research on the method of dyeing textile fabrics with vegetable dyes into blue

Embodiment Construction

[0024] A method for dyeing protein fiber fabrics with natural plant dyes. The dyeing method includes preparing natural plant dyes from gardenias and dyeing protein fiber fabrics blue with the prepared natural plant dyes. The specific method steps are as follows:

[0025] (1) Take a certain weight of air-dried gardenias, crush the gardenias first, and then pass through a 15-30 mesh sieve to obtain crushed gardenias

[0026] (2) Put the crushed gardenia fruit into a container, add petroleum ether 5-8 times the weight of the gardenia fruit, ultrasonically extract for 40-60 minutes, filter under reduced pressure to obtain filtrate I and filter residue I; the filter residue I can be refilled into the container Inside, repeat the operation twice according to the above method, and the finally obtained filter residue I is used to prepare natural vegetable dyes; this step mainly uses petroleum ether to remove vegetable oil and pectin in the broken gardenia fruit, and the filtrate I obtained ...

Abstract

The invention provides a method for dyeing a protein fiber fabric through a natural plant dye .The dyeing method comprises the steps that the natural plant dye obtained from cape jasmine fruits is used for dyeing the protein fiber fabric blue, the cape jasmine fruits are smashed and screened, plant oil and pectin are removed, purification and concentration are performed, a macroporous resin column is adopted, cellulose is added, and the natural plant dye is obtained; surface impurities are removed after the protein fiber fabric is pretreated, rare earth or a rare earth derivative is added, the obtained natural plant dye is added, the protein fiber fabric is dyed blue, finally, and the dyed fabric is washed with water, soaped, rinsed, dehydrated and dried in the shade to obtain the blue protein fiber fabric .According to the dyeing method, the natural plant dye obtained from the cape jasmine fruits is adopted for dyeing the protein fiber fabric blue, the dyeing effect is good, the whole process can be easily and accurately controlled, large-scale production can be carried out, and the obtained protein fiber fabric has the natural antibacterial effect.

Description

Technical field [0001] The invention relates to the field of textile dyeing and finishing, in particular to a method for dyeing protein fiber fabrics blue by using natural plant dyes prepared from gardenia fruit. Background technique [0002] At this stage, most printing and dyeing companies use chemical dyes, such as reactive dyes, disperse dyes, acid dyes and cationic dyes, etc. These dyes are artificially synthesized from coal and petroleum as raw materials as intermediates, which have a serious impact on the environment. Moreover, some chemical dyes are irritating and allergic to human skin, which is not good for health. [0003] Compared with chemical dyes, natural dyes have natural and bright colors and high safety. Some natural dyes also have certain health-care functions and are deeply loved by people. Vegetable dyes are the dyes with the longest application history and the widest application range among natural dyes. Plant dyes are mainly extracted from the stems, leaves...
