Problems solved by technology

However, the tone of the bamboo chip itself is relatively single, which cannot meet the needs of the market, and cannot achieve the effect of improving visual effects and increasing product added value. There are many deficiencies in the existing bamboo dyeing process: first, the color fastness after dyeing is not good. Horizontal organization is not conducive to the lateral penetration of dyes, so the dyed products show false color, light color, easy to fade, and easy to change color; secondly, most of the dyes used are artificial chemically synthesized dyes, which cause certain pollution to the environment
[0004] However, the technical literature on the application of walnut skin to bamboo dyeing has not been disclosed, and some research and development is necessary.

Embodiment 1

[0024] Embodiment 1: the direct dyeing method of walnut skin vegetable dyestuff to thin bamboo sheet

[0025] Add water in the high-pressure container at a bath ratio of 1:10, add plant dye powder at a concentration of 1g / L, adjust the pH value to 9-11, add 0.1-0.5g / L penetrating agent, and put the thin bamboo presoaked in clear water Put the bamboo slices into the dyeing solution, control the thickness of the bamboo slices at 0.2-1mm, cover the high-pressure container tightly, heat to 130°C, keep warm for 20 minutes, cool to room temperature, take out the dyed bamboo slices, rinse with water and dry, the color is red brown.

[0026] Present embodiment uses walnut skin to dye bamboo slices, and the gained bamboo slices color is reddish-brown, simple and unsophisticated, natural in color and luster; There is the effect of imitating teak wood, walnut wood, and color fastness is better, and dry rubbing fastness reaches 4-5 grades, Wet rubbing fastness reaches grade 3-4. The pro...

Embodiment 2

[0027] Embodiment 2: the mordant dyeing method of walnut skin plant dyestuff to thin bamboo slice

[0028] Add water in the high-pressure container at a bath ratio of 1:10, add plant dye powder at a concentration of 1g / L, adjust the pH value to 11, add 0.1-0.5g / L penetrating agent, and put the thin bamboo slices pre-soaked in clear water into In the dyeing solution, cover the high-pressure container tightly, heat to 130 ° C, keep warm for 20 minutes, cool to room temperature, take out the dyed bamboo slices, rinse with clean water, put the dyed bamboo slices into a bath containing mordant 2g / L solution, the bath ratio is 1:10, after mordant dyeing at room temperature for 5 hours, the bamboo slices are taken out, rinsed and dried in clear water, the color of the obtained bamboo slices is greenish brown or yellowish brown, which is darker than that obtained by direct dyeing method.

[0029] In this example, walnut skin is used to dye bamboo slices, and mordant is used for mordan...

Embodiment 3

[0030] Example 3: Add water in a high-pressure container at a bath ratio of 1:5, add plant dye powder at a concentration of 0.5g / L, adjust the pH to 9, add 0.5g / L of penetrating agent, and pre-soak the thin film with clear water. Put the bamboo slices into the dyeing solution, cover the high-pressure container tightly, heat to 120°C, keep warm for 40 minutes, cool to room temperature, take out the dyed bamboo slices, rinse with water and dry, the color is reddish brown.

[0031] Present embodiment uses walnut skin to dye bamboo slices, and the gained bamboo slices color is reddish-brown, simple and unsophisticated, natural in color and luster; There is the effect of imitating teak wood, walnut wood, and color fastness is better, and dry rubbing fastness reaches 4-5 grades, Wet rubbing fastness reaches grade 3-4. The process of dyeing bamboo chips with walnut skin vegetable dyes is simple, environmentally friendly, low in cost, can be used as waste, and there is no environmenta...

Abstract

The invention discloses a method for dyeing a bamboo chip by a walnut skin plant dye, successively comprising the following steps: (1) piling collected outer walnut skins, naturally fermenting after the walnut skins are heated, and drying to obtain a puce massive plant dye raw material; (2) smashing the above plant dye raw material to obtain dye powder, adding the dye powder into a container filled with bath lotion, meanwhile adding a penetrating agent, adjusting the pH value of dye liquor to 9-11, adding the bamboo chip, sealing the container, heating to 120-140DEG C, and dipping; and (3) cooling to room temperature after dipping, taking out the bamboo chip, cleaning with clear water, and drying to obtain the rufous bamboo chip. The invention also discloses a method for dyeing brown green bamboo chips. Compared with the prior art, the method has the advantages of simple technology because of dying the bamboo chips by the walnut skins, abundant raw materials and good dry and wet friction colour fastness after dyeing, is safe, reliable and free from pollution and can ensure that the bamboo chips do not fade for a long time.

Description

technical field [0001] The invention relates to a method for dyeing bamboo slices, in particular to a method for dyeing bamboo slices by using walnut exocarp. Background technique [0002] Bamboo has the advantages of rich resources, short time to become useful, high yield, strong reproductive ability, and environmental protection, which makes bamboo products more and more widely used. Thin bamboo chips can be made into special wallpaper after being processed in the factory, which can be used in home decoration, and can also be made into various handicrafts and household items. However, the tone of the bamboo chip itself is relatively single, which cannot meet the needs of the market, and cannot achieve the effect of improving visual effects and increasing product added value. There are many deficiencies in the existing bamboo dyeing process: first, the color fastness after dyeing is not good. Horizontal organization is not conducive to the lateral penetration of dyes, so t...
