Problems solved by technology

Natural dyes refer to dyes obtained from plants, animals or mineral resources, without artificial synthesis, with little or no chemical processing, but the existing purple rice natural dyes have a relatively small scope of application, and the purple rice dyes Spray-dyeing equipment is required for spray-dyeing, but common spray-dyeing equipment is not convenient for multi-directional spray-dyeing of products, and because there are more or less certain impurities in the dye, it is very easy to cause damage during the spray-dyeing process. The blockage of the nozzle is not only inconvenient to clean, but also reduces the spraying efficiency, thus greatly reducing the practicability of the device

Embodiment 1

[0051] Such as figure 1 Shown in, the preparation method of the purple rice natural dye provided by the invention comprises the following steps:

[0052] S1. Put the above-mentioned purple rice pigment, sodium alginate, neutral red, organic solvent, iron ion, emulsifier, basic fuchsin, safranin and cellulose ether into the stirring tank in turn for stirring and mixing. The rotation speed is 1000R / min-1500R / min, stirring for 40 minutes, while stirring, put an organic solvent into it, continue stirring for 20 minutes, and make it fully mixed;

[0053] S2. The uniformly stirred mixture in S1 is left to ferment, and the fermentation time is controlled within 5-8 days;

[0054] S3. Filter the mixture after fermentation in S2 through a filter device to filter out impurities in the mixture, then place it in a pot, heat and boil it, and control the temperature after boiling between 75°C and 85°C , at the same time, put solid green into it, make it react with the mixed solution, and ...

Embodiment 2

[0058] The purple rice natural dye of the present invention comprises the following components in parts by weight: 35 parts of purple rice pigment, 5 parts of sodium alginate, 22 parts of fast green, 18 parts of neutral red, 8 parts of Several parts of organic solvent, 16 parts of iron ion, 12 parts of emulsifier, 19 parts of basic fuchsin, 11 parts of safranin and 2.2 parts of cellulose ether.

Embodiment 3

[0060] The purple rice natural dye of the present invention comprises the following components in parts by weight: 32 parts of purple rice pigment, 2.5 parts of sodium alginate, 18 parts of fast green, 11 parts of neutral red, 5.5 parts Several parts of organic solvent, 11.5 parts of iron ion, 8.5 parts of emulsifier, 14.5 parts of basic fuchsin, 8.5 parts of safranin and 1.2 parts of cellulose ether.

[0061] Known by above-mentioned three examples: the purple rice natural dye that obtains in embodiment 1 is poor in coloring effect, easily fades, and the purple rice natural dye that obtains in embodiment 2 is good in color, but fixation effect is relatively poor, and The purple rice natural dye obtained in Example 3 not only has better coloring effect, but also is not easy to fade, so it is the best formula.

Abstract

The invention discloses a purple rice natural dye and spray dyeing equipment used by the same. The purple rice natural dye is prepared from the following components in parts by weight: 25 to 35 parts of purple rice pigment, 1 to 5 parts of sodium alginate, 13 to 22 parts of fast green, 5 to 18 parts of neutral red, 2 to 8 parts of an organic solvent, 8 to 16 parts of iron ions, 3 to 12 parts of an emulsifier, 13 to 19 parts of basic fuchsin, 6 to 11 parts of sarranine and 0.8 to 2.2 parts of cellulose ether. The natural purple rice dye prepared according to the formula is free of peculiar smell, good in coloring effect and better in color fixing effect, the spray dyeing equipment used by the natural purple rice dye can conduct all-directional spraying on products, the dye in a storage barrel can be evenly stirred and mixed all the time in the spraying process, therefore, the dye can be effectively prevented from being precipitated during spraying, and the practicability is good.

Description

technical field [0001] The present invention relates to the technical field of purple rice natural dye and its preparation method and the spray-dyeing equipment used, in particular to a purple rice natural dye and its preparation method, and especially to a purple rice natural dye spray-dyeing equipment . Background technique [0002] Dyes are colored substances. But a colored substance is not necessarily a dye. As a dye, it must be able to attach a certain color to the fiber, and it is not easy to fall off and change color. Dyes are usually soluble in water, and some dyes require a mordant to make the dye stick to the fiber. Natural dyes refer to dyes obtained from plants, animals or mineral resources, without artificial synthesis, with little or no chemical processing, but the existing purple rice natural dyes have a relatively small scope of application, and the purple rice dyes Spray-dyeing equipment is required for spray-dyeing, but common spray-dyeing equipment is ...
