Problems solved by technology

Due to the great difference in the combination degree of different plant dyes and fibers, color matching is more difficult, and the shade of the dye obtained after color matching is poor, which further leads to less color spectrum of plant dyes, which cannot meet the needs of printing, making plant dye printing basically unrealistic at present. economic value

Embodiment 1

[0033]A plant dye color printing process using 40S + 30D bamboo extract, door width weight 180cm * 210, including the following steps: 1) The pre-treatment gray fabric, adjusted with citric acid to be printed with the pH of 7.1.

[0034]2) Color paste:

[0035]1 # Orange: 5% of Guar Tom Gum, 1% citric acid, 2% acid gradation orange, 1% antioxidant

[0036]Add 100% of ion water synthesis;

[0037]2 # Brown: Guar bean gum 2% + tamarind 5%, citrate 1%, 2% sour orange 2% + sand color, 1% anti-oxidant, add ion water to synthesize 100%;

[0038]3 # Dark Brown: Guar Beans 2% + 4% of Luozi, 1.5% citric acid, 2% of sour orange, 2% of the sand color, 2% antioxidants, and add 100% of ionic water;

[0039]4 # Black: 5% of the alginate 5% + pure base, 10% fermentation sugar, 5% bamboo charcoal, and 100% of ion water;

[0040]5 # Yellow: Guar Beans 2% + Tamaro 5%, 1% citric acid, 3% 黄 黄 0.2%, ion orange 0.2%, add ionized water to synthesize 100%;

[0041]6 # Green: 5% of Guar Tom Gum, 1% citric acid, 0.8% 姬 蓝 蓝 0.8% + 黄...

Embodiment 2

[0050]A plant dye color printing process using 50S cotton cotton hair, door width weight: 185 cm * 195g, including the following steps: 1) The front treatment gray fabric is adjusted to be 6.4.

[0051]2) Color paste

[0052]1 # Green: 5% citric acid 1%, olive green 20g / L + hay color 5g / L

[0053]Add 100% of ion water synthesis;

[0054]2 # orange: Guar bean gum 5%, 1% citric acid, orange 15g / L + rouge red 5g / L

[0055]Antioxidant 1%, add ionized water to synthesize 100%.

[0056]3) Print: Magnetic rod 8 #, 150 mesh screen, vehicle speed 30m / min.

[0057]4) Dry: Temperature 120 ° C.

[0058]5) Steaming: Temperature 130 ° C * 5 min, the temperature must be grasped, too low, can not be fully color, too high affecting the color light.

[0059]6) Wash: Plant dye is low in cotton, floating, so the water is washed, and the pH is 7.5.

[0060]7) Set. Temperature control 130 ° C, speed of 28m.

Embodiment 3

[0062]A plant dye color-fitting process, on the basis of Example 1, the vaporization temperature was set to 140 ° C.

Abstract

The invention discloses a vegetable dye color matching and printing process, and belongs to the technical field of vegetable dye printing. Due to good environmental compatibility and resource reproducibility of vegetable dyes, numerous dye plants have the effects of bacteriostasis, ultraviolet prevention and the like. Due to the fact that the vegetable dyes are large in structure difference and poor in compatibility, color matching is difficult, and application of the vegetable dyes to printing is relatively little. According to the invention, appropriate conditions such as a preparation method, the ageing temperature and the washing pH of vegetable dye color paste are found, the compatibility among various different vegetable dyes is improved, the color matching and printing effect of the vegetable dyes is remarkably improved, and meanwhile, rosemary extract is provided as an antioxidant and can be better matched with the vegetable dyes, so that the economic value of vegetable dye printing is improved.

Description

Technical field[0001]A plant dye color printing process belongs to the field of plant dye printing technology.Background technique[0002]The plant dye is due to its good environment compatibility, the renewability of resources, and many dye plants have the effects of bacteriostatic and anti-UV line, causing attention to many research and application institutions at home and abroad, plant dyes research and development and application have achieved large Progress, the fabric whose plants dye is increasingly welcomed.[0003]Whether it is domestic or foreign, the study of plant dyes is currently concentrated on the dyeing of plant dyes, due to the difference in structural dyes, poor integration between dyes, and the color matching, leading to printing There is fewer applications, and the fabric can be fully proliferated into the fiber in the dye bath, and the printing is the evaporation of the post-treatment, and the dye is increased to increase the diffusion rate of the dye. Due to the d...
