Embodiment 1

[0046] The process of printing and dyeing animal skin with mulberry juice comprises the following steps:

[0047] a. Preparation of mulberry dye: take mulberries, ultrafinely pulverize them to obtain mulberry juice, then add alcohol with a concentration of 80%, the ratio of the volume of the alcohol to the mass of mulberries is 7:1, soak for 15 hours, and use a 100-mesh screen Filtrate 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 vacuum-dry to obtain a solid, that is, mulberry dye;

[0048] b. Dye preparation: take the following components in parts by weight: 30 parts of mulberry 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 hom...

Embodiment 2

[0054] A process for printing and dyeing animal skins using mulberry juice, comprising the steps of:

[0055] a. Preparation of mulberry dye: take mulberries, ultrafinely pulverize them to obtain mulberry juice, then add alcohol with a concentration of 80%, the ratio of the volume of the alcohol to the mass of mulberries is 5:1, soak for 12 hours, and use an 80-mesh screen Filtrate and collect the filtrate; then impregnate the filter residue with the same alcohol for 12 hours, filter with an 80-mesh sieve, and collect the filtrate; combine the filtrate collected twice, concentrate, and dry in vacuo to obtain a solid, namely mulberry dye;

[0056] b. Dye preparation: take the following components in parts by weight: 28 parts of mulberry 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-mentioned components were mixed and stirred homogeneously to obt...

Embodiment 3

[0062] A process for printing and dyeing animal skins using mulberry juice, comprising the steps of:

[0063] a. Preparation of mulberry dye: take mulberries, ultrafinely pulverize them to obtain mulberry juice, then add alcohol with a concentration of 80%, the ratio of the volume of the alcohol to the mass of mulberries is 10:1, soak for 24 hours, and use a 100-mesh screen Filtrate 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 filtrate collected twice, concentrate, and vacuum-dry to obtain a solid, that is, mulberry dye;

[0064] b. Dye preparation: take the following components in parts by weight: 32 parts of mulberry dye obtained through step a, 6 parts of tannin extract, 2.5 parts of crosslinking color-fixing agent DE, 1.2 parts of sodium dioctyl succinate sulfonate , 0.5 parts of sodium chloride and 60 parts of water; the above components are mixed and ...

Abstract

The invention relates to a technology for printing and dyeing animal skin through mulberry juice. The technology includes the following steps that a, mulberry dye is prepared; b, the dye is compounded; c, the animal skin is treated; d, dyeing is conducted; e, hot steaming is carried out; f, after treatment is performed. By the adoption of the printing and dyeing technology, the adhesive force of plant dye on leather can be increased, and the printed and dyed leather is not prone to fading and losing colors.

Description

technical field [0001] The invention relates to the field of leather printing and dyeing technology, in particular to a technology of using mulberry juice to print and dye animal skin. 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 beneficial Human health, but ...
