Embodiment 1

[0048] The process of printing and dyeing artificial leather with mustard juice comprises the following steps:

[0049] a. Preparation of mustard dye: take mustard, ultrafinely pulverize it to obtain mustard juice, then add alcohol with a concentration of 80%, the ratio of the volume of the alcohol to the mass of mustard is 7:1, soak for 15 hours, and filter with a 100-mesh sieve , collect the filtrate; then impregnate the filter residue with the same alcohol, filter with a 100-mesh screen for 14 hours, and collect the filtrate; combine the filtrate collected twice, concentrate, and dry in vacuo to obtain a solid, i.e. mustard dye;

[0050] b. Dye preparation: take the following components in parts by weight: 30 parts of mustard dye obtained through step a, 5 parts of tannin extract, 2.3 parts of cetylpyridinium chloride, and 1.1 parts of sodium dioctyl succinate sulfonate , 0.3 parts of sodium chloride and 50 parts of water; the above components are mixed and homogeneously st...

Embodiment 2

[0056] A process for printing and dyeing artificial leather utilizing mustard juice, comprising the steps of:

[0057] a. Preparation of mustard dye: take mustard, ultrafinely pulverize it to obtain mustard juice, then add alcohol with a concentration of 80%, the ratio of the volume of the alcohol to the mass of mustard is 5:1, soak for 12 hours, and filter with an 80-mesh sieve , collect the filtrate; then impregnate the filter residue with the same alcohol for 12h, filter with an 80-mesh sieve, and collect the filtrate; combine the filtrates collected twice, concentrate, and dry in vacuo to obtain a solid, i.e. mustard dye;

[0058] b. Dye preparation: take the following components in parts by weight: 28 parts of mustard dye obtained through step a, 4 parts of tannin extract, 1.5 parts of cetylpyridinium bromide, 0.8 part of lecithin, and 0.2 part of sodium chloride and 40 parts of water; the above components are mixed and stirred homogeneously to obtain the dye;

Embodiment 3

[0064] A process for printing and dyeing artificial leather utilizing mustard juice, comprising the steps of:

[0065] a. Preparation of mustard dye: take mustard, ultrafinely pulverize it to obtain mustard juice, then add alcohol with a concentration of 80%, the ratio of the volume of the alcohol to the mass of mustard is 10:1, soak for 24 hours, and filter with a 100-mesh sieve , collect the filtrate; then impregnate the filter residue with the same alcohol, 24h, filter with a 100-mesh sieve, and collect the filtrate; combine the filtrates collected twice, concentrate, and dry in vacuo to obtain a solid, i.e. mustard dye;

[0066] b. Dye preparation: take the following components in parts by weight: 32 parts of mustard dye obtained through step a, 6 parts of tannin extract, 2.5 parts of crosslinking color-fixing agent DE, 1.2 parts of dioctyl sodium sulfosuccinate, 0.5 parts of sodium chloride and 60 parts of water; the above components are mixed and homogeneously stirred to...

Abstract

The invention relates to a process for printing and dyeing artificial leather by using leaf mustard juice, comprising the following steps: a, preparing a leaf mustard dye; b, preparing a dye; c, treating the artificial leather; d, dyeing; e, heating for evaporation; f, performing afterfinish. The printing and dyeing process can improve the attachment of the vegetable dye on the artificial leather, so that the printed and dyed artificial leather is not easy to fade.

Description

technical field [0001] The invention relates to the field of artificial leather printing and dyeing technology, in particular to a technology for printing and dyeing artificial leather by using mustard juice. Background technique [0002] The deterioration of environmental quality and the imbalance of ecological balance have made human beings face a serious environmental crisis. Industrial production is a major source of environmental pollution, among which the printing and dyeing industry bears the brunt. Dye wastewater has deep chroma, high content of organic pollutants, complex components, heavy metals and biological toxicity, and is difficult to biodegrade. The dye has strong resistance to photolysis and oxidation, and contains a variety of organic substances that are biologically toxic or cause "three causes" performance , which is very harmful to environmental pollution. [0003] In order to protect the environment, return a suitable living environment for human bein...
