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

[0025] A method for dyeing cotton fiber fabrics with natural vegetable dyes, the dyeing method adopts natural vegetable dyes produced from gardenia fruit to dye cotton fiber fabrics blue, and the specific method steps are as follows:

[0026] (1) Take a certain weight of air-dried gardenia fruit, first crush the gardenia fruit, and then pass through a 15-30 mesh sieve to obtain broken gardenia fruit;

[0027] (2) Put the crushed gardenia fruit into a container, add petroleum ether 5 to 8 times the weight of the gardenia fruit, ultrasonically extract for 40 to 60 minutes, and filter under reduced pressure to obtain the filtrate I and filter residue I; the filter residue I can be put into the container again 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 crushed gardenia fruit, and the filtrate I obtained t...

Abstract

The invention provides a method for dyeing cotton fiber fabric through natural plant dye .According to the method, the natural plant dye prepared from gardenia fruit is adopted for dyeing the cotton fiber fabric into blue, the gardenia fruit is subjected to the steps of crushing, screening, plant oil and pectin removing, purification, concentration, macroporous resin column applying, cellulase adding and the like, and then the natural plant dye is obtained; the cotton fiber fabric is subjected to pretreatment so that surface impurities can be removed, then a setting machine is used for soaking the cotton fiber fabric twice and rolling the cotton fiber fabric twice, then sodium bicarbonate is used for treatment, rare earth or a rare earth derivative is added, then the obtained plant dye is added, the cotton fiber fabric is dyed into blue, and finally water washing, soaping, rinsing, dehydrating, drying and setting are carried out to obtain the blue cotton fiber fabric .According to the dyeing method, the natural plant dye prepared from the gardenia fruit is adopted for dyeing the cotton fiber fabric into blue, the dyeing effect is good, precise control over the whole process is easy, large-scale production can be carried out, and the cotton fiber fabric obtained through dyeing has a 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 cotton fabrics blue with natural plant dyes prepared from gardenia fruits. Background technique [0002] At present, most of the printing and dyeing enterprises use chemical dyes, such as reactive dyes, disperse dyes, acid dyes and cationic dyes, etc. These are dyes produced artificially from coal oil 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 conducive to health. [0003] Compared with chemical dyes, natural dyes have natural bright colors and high safety, and some natural dyes also have certain health care functions, which are very popular among 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 plant stems, leav...
