Description
Technical field
The present invention relates to leather technology field field of printing and dyeing, and in particular to a kind of work using strawberry juice printing and dyeing Animal Skin
Skill.
Background technology
Printing and dyeing are also referred to as dyeing and finishing.Dye molecule is formed surely after being handled by physical and chemical process with cloth or leather green body
Surely it combines.Plant printing and dyeing refers to using the extraction pigment such as flower, grass, tree, wood, leaf, stem, fruit, kind, skin, root of nature to spinning
Fabric is painted, and this method is known as " vegetation dye " in ancient times.Early in the Neolithic Age, people begin to use natural plant to contaminate
Material.It has been found that the root of flowers and fruits, stem, leaf, skin can extract dye liquor with warm water immersion all over the mountains and plains.
During vegetable colour prints and dyes Animal Skin, dye molecule is by hydrogen bond and belongs to water key and the glue in Animal Skin
Original combines, to increase the binding force of vegetable colour and animal's leather.
The main component of strawberry pigment is pelargonin -3-O- glucosides, and No. CAS is 18466-51-8, is a kind of
Preferable red stain, can be as the coloring of food, beverage toy for children etc..But because strawberry pigment is soluble easily in water, ethyl alcohol etc.
Substance, so, strawberry pigment print and dye Animal Skin there may be dyeing loosely, washing property it is poor the problems such as.

Specific embodiment
A kind of technique using strawberry juice printing and dyeing Animal Skin includes the following steps：
A. strawberry juice dyestuff is prepared：Strawberry pulp is taken, then ultramicro grinding adds in absolute ethyl alcohol, the absolute ethyl alcohol
Volume and the mass ratio of strawberry are 5-10:1,12-24h is impregnated, with the screen filtration of 80-100 mesh, collects filtrate；Then will
Filter residue is impregnated using identical absolute ethyl alcohol, 12-24h, with the screen filtration of 80-100 mesh, collects filtrate；Merging is collected twice
The filtrate arrived concentrates, and vacuum drying obtains solid, i.e. strawberry juice dyestuff；
B. dye solution is prepared：Following component is taken according to weight：28-32 parts of strawberry juice dyestuff, the tannin extract obtained by a steps
40-60 parts of 4-6 parts, 1.5-2.5 parts of color fixing agent, 0.8-1.2 parts of surfactant, 0.2-0.5 parts of sodium chloride and water；It will be above-mentioned each
Component mixes, and homogeneous stirring obtains dye solution；
Tannin extract in the step, the general name of a kind of complicated native compound.It is also non-wherein in addition to main component tannin
Tannin and insoluble matter, including but not limited to chestnut extract, oak tannin extract and larch bark tannin extract；Color fixing agent in the step,
Can be the color fixing agent of field of printing and dyeing, including but not limited to cetylpyridinium chloride and brocide and crosslinking
Color fixing agent DE；Color fixing agent in the step can be the surfactant of field of printing and dyeing, including but not limited to lecithin, ten
Dialkyl benzene sulfonic acids sodium, dioctyl succinate disulfonate acid and Tween-80；
The general adhesive force of phytochrome is relatively low, in dyeing and printing process of the invention, by adding in color fixing agent and containing tannin
Tannin extract as mordant, enable to the ligands such as hydroxyl, carboxyl contained on phytochrome molecule and in Animal Skin
Contained hydroxyl forms complicated multicomponent complex on collagenous fibres molecule so that phytochrome and the collagenous fibres in Animal Skin
Active force increase between molecule, promotes adhesive force of the vegetable colour in Animal Skin；
C. Animal Skin is handled：Learning from else's experience tanning treated, Animal Skin carries out acidleach, neutralisation treatment, the acid solution that acidleach uses
PH value is 1.5-2.5；Neutralisation treatment is specially：Alkali is added in the acid solution of dipping and is neutralized 30-45min, per 5min
Improve pH value 0.4-0.6；

Steam under heat steam 30-90min；
After dyeing, hot steaming processing is carried out, can speed up the movement of Animal Skin plants on surface pigment molecular, and by collagen
Gap is further opened between fiber so that phytochrome molecule enters the higher depth of Animal Skin so that the plant on Animal Skin surface
Pigment molecular is less, and the fixation ability of Animal Skin is stronger；
F. final finishing：It will be cleaned by the Animal Skin of step e processing with clear water, shady place air-dries.
In the present invention, preferred scheme further includes a patterning step between the Step d and step e：Using printing machine
Stamp processing is carried out to the Animal Skin by Step d processing, the environment temperature that stamp is handled is 25-35 DEG C, humidity 35-
50%.Using the stamp processing environment of above-mentioned temperature and humidity range, enable to printing quality more preferable.
In the present invention, preferred scheme is that the clear water cleaning in the f steps is specially：It is cleaned with clear water by step e
The Animal Skin 30s of processing is cleaned 2-3 times.
