Embodiment 1

[0046] The process of printing and dyeing artificial leather with kiwi fruit juice comprises the following steps:

[0047] a. Preparation of kiwi fruit dye: take kiwi fruit pulp, superfinely pulverize it to obtain kiwi fruit 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 vacuum to obtain a solid, namely kiwi fruit dye;

[0048] b. Dye preparation: take the following components in parts by weight: 30 parts of kiwifruit dye obtained through step a, 5 parts of tannin extract, 2.3 parts of cetylpyridinium chloride, 1.1 parts of sodium dioctyl succinate sulfonate part, 0.3 part of sodium chloride and 50 parts of water; the above components are mixed and homogeneously stirred to obtain the dye;

[0049] c. Artificial leather tr...

Abstract

The invention relates to a technology for printing and dyeing artificial leather by using a kiwi fruit juice. The technology comprises the following steps: 1, preparing a kiwi fruit dye; 2, preparing a dye; 3, processing artificial leather; 4, dyeing the artificial leather; 5, carrying out heating evaporation on the artificial leather; and 6, after-finishing the artificial leather. The printing and dyeing technology can improve the adhesion of plant dyes on leather, and makes the color of the printed and dyed leather difficultly 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 kiwi fruit 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 beneficial Hu...
