Embodiment 1

[0043] Get 10g of natural dye sorghum red and place it in 1L of water to prepare 1L of 10g / L sorghum red solution. Take 1g of sorghum red solution and place it in 20g of molten beeswax, and stir it at 8000r / min for 15min to make sorghum red batik emulsion.

[0044] Heat the sorghum red batik emulsion to 72°C, and use the sorghum red batik emulsion to draw patterns on the primary color vegetable tanned leather. Afterwards, the vegetable tanned leather with the pattern is blown for 30s at 70° C. with a hot air dryer. Paint the area not batiked with colorless beeswax, and blow it with a hot air dryer at 70°C for 30s. Finally, the sorghum red dye remaining on the vegetable tanned leather is collected.

Embodiment 2

[0046] Take 20g of natural dye copper chlorophyllin sodium salt and place it in 1L of water to prepare a 20g / L copper chlorophyllin sodium salt solution. Take 1g of copper chlorophyllin sodium salt solution and place it in 20g of molten beeswax, and stir for 30min at 10000r / min to prepare copper chlorophyllin sodium salt batik emulsion.

[0047] Heat the sodium copper chlorophyllin batik emulsion to 70°C, and use the sodium copper chlorophyllin batik emulsion to draw patterns on the primary color vegetable tanned leather. Afterwards, the vegetable tanned leather with the pattern is blown for 60s at 75° C. with a hot air dryer. Paint the area not batiked with colorless beeswax, and blow it with a hot air dryer at 70°C for 60s. Finally, the copper chlorophyllin sodium salt dye remaining on the vegetable tanned leather was collected.

Embodiment 3

[0049] Take a total of 40 g of natural dye copper chlorophyllin sodium salt and pomegranate peel mixed dye, put it in 1 L of water, and prepare a 40 g / L mixed dye solution. Take 1g of the mixed dye solution and place it in 20g of melted beeswax, and stir it for 40min at 12000r / min to prepare the mixed dye batik emulsion.

[0050] Heat the mixed dye batik emulsion to 74°C, and use the mixed dye batik emulsion to draw patterns on the primary color vegetable tanned leather. Afterwards, the vegetable tanned leather with pattern is blown for 90s at 78° C. with a hot air dryer. Use colorless beeswax liquid to paint the area that has not been wax painted, and blow it with a hot air dryer at 70°C for 120s. Finally, the residual copper chlorophyllin sodium salt and pomegranate peel mixed dyes were collected on the vegetable tanned leather.

Abstract

The invention relates to a wax dyeing dye, a vegetable tanned leather wax dyeing product and a vegetable tanned leather wax dyeing method. The wax dyeing dye is an emulsion, and the wax dyeing dye comprises the following components: a dye, water and beeswax. The wax dyeing dye is produced into the emulsion by coating the dye with the beeswax, and dye particles coated with the wax have a good dyeing effect, so that the dyeing fastness of vegetable tanned leather wax dyeing is improved; in addition, the wax dyeing dye contains the dye and the beeswax, so that dyeing and waxing processes can be finished in one step, the need of dyeing and waxing separately is avoided, and thus a wax dyeing technology is simplified.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a batik dye, a vegetable tanned leather batik product and a vegetable tanned leather batik method. Background technique [0002] In recent years, with the improvement of people's living standards and the enhancement of environmental awareness, consumers are more keen on purchasing personalized and green leather products. Vegetable tanned leather is increasingly favored by consumers because it is tanned with vegetable tannins and does not contain harmful substances to the human body. However, vegetable tanned leather has good hygroscopicity and plasticity in wet state, it is easy to get dirty during use, and it is easy to deform after absorbing water. Therefore, vegetable tanned leather must be coated with anti-dyeing agent on the surface before use to avoid pollution and water absorption deformation. [0003] Batik is an ancient folk printing and dyeing handicraft in my country....
