Embodiment 1

[0047] The process of printing and dyeing artificial leather with mangosteen bark juice comprises the following steps:

[0048] a. Preparation of mangosteen skin dye: take mangosteen skin, superfinely pulverize it to obtain mangosteen skin juice and then add alcohol with a concentration of 80%. Filter through the purpose sieve to collect the filtrate; then impregnate the filter residue with the same alcohol for 14 hours, filter through a 100-mesh sieve, and collect the filtrate; combine the filtrate collected twice, concentrate, and dry in vacuo to obtain a solid, i.e. mangosteen bark dye;

[0049] b. Dye preparation: take the following components in parts by weight: 30 parts of mangosteen bark dye obtained through step a, 5 parts of tannin extract, 2.3 parts of cetylpyridinium chloride, 1.1 parts of sodium dioctyl sulfosuccinate part, 0.3 part of sodium chloride and 50 parts of water; the above-mentioned components are mixed and stirred homogeneously to obtain the dye;

Embodiment 3

[0063] A process for printing and dyeing artificial leather utilizing mangosteen bark juice, comprising the steps of:

[0064] a. Mangosteen bark dye preparation: take mangosteen bark, ultrafine pulverize, and then add the alcohol with a concentration of 80% to obtain mangosteen bark juice, the ratio of the volume of the alcohol to the mass of mangosteen bark is 10:1, soak for 24h, use 100 Filter through the purpose sieve to collect the filtrate; then impregnate the filter residue with the same alcohol for 24 hours, filter through a 100-mesh sieve, and collect the filtrate; combine the filtrates collected twice, concentrate, and dry in vacuo to obtain a solid, i.e. mangosteen bark dye;

[0065] b. Dye preparation: take the following components in parts by weight: 32 parts of mangosteen bark dye obtained through step a, 6 parts of tannin extract, 2.5 parts of crosslinking color-fixing agent DE, and 1.2 parts of sodium dioctyl succinate sulfonate , 0.5 parts of sodium chloride a...

Abstract

The invention relates to a process for printing and dyeing artificial leather by using mangosteen bark juice, comprising the following steps: a, preparing a mangosteen bark dye: taking mangosteen bark, performing superfine grinding to obtain the mangosteen bark juice, then adding ethyl alcohol with the concentration of 80 percent, dipping for 12-24h, filtering with a sieve of 80-100 meshes, and collecting filter liquor, wherein a ratio of the volume of the ethyl alcohol to the mass of the mangosteen bark is (5 to 10) : 1; dipping filter residues by adopting the same ethyl alcohol for 12-24h, filtering with a sieve of 80-100 meshes, and collecting filter liquor; combining filter liquor obtained by two times of collecting, concentrating, and vacuum-drying to obtain the solid, i.e., the mangosteen bark 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 leather, so that the printed and dyed leather is not easy to fade.

Description

technical field [0001] The invention relates to the field of leather printing and dyeing technology, in particular to a technology for printing and dyeing artificial leather by using mangosteen bark juice. Background technique [0002] Printing and dyeing is also called dyeing and finishing. After the dye molecules are processed by physical and chemical processes, they form a stable combination with the cloth or leather body. During the printing and dyeing process, the usual chemically synthesized dyes will produce a lot of pollution, and there will be more substances harmful to human health on the dyed and printed cloth or leather, which is not conducive to human health. For this reason, people have discovered natural dyes in the process of printing and dyeing, mainly vegetable dyes for printing and dyeing cloth, leather, etc., which can not only achieve better printing and dyeing effects, but also avoid harmful substances remaining in leather and cloth, which is beneficia...
