The present invention provides a kind of dye black-labour skills of fur, include the following steps, after fur cladding and dye plate dyestuff are carried out high temperature dye plate first, obtain semi-finished product；Then after the semi-finished product and dye plate dyestuff above-mentioned steps obtained carry out retanning fixation, the fur cladding after obtaining fixation；Fur cladding, dye plate dyestuff and the dye hair dyestuff after fixation that above-mentioned steps obtain finally are carried out high temperature hair plates to contaminate altogether, the fur after being dyed after cleaning.Each key point technology is carried out creative optimization and combined by the present invention, plate+dye hair-cleaning process flow is contaminated using high temperature dye plate-retanning fixation-high temperature, dye plate carries out in two times, it first carries out high temperature and contaminates plate, hair plates is carried out after fixation at high temperature again to contaminate altogether, to improve dyestuff absorptivity, and uniform coloring, tone are full, coloration is high.The reduction of dye dosage is realized, and also improves coloration, significantly improves Bearable dry and wet wipe color fastness.
Description
Technical field
The invention belongs to leather processing technical field, in particular to the dye black-labour skill of a kind of fur.
Background technique
The processing of leather has had thousands of years history, and by developing for a long time, process hides is from original originally simple
Manual operations, develop as an important industrial technical field.From in the early 1980s, the leather industry in China is dashed forward
Fly the development pushed ahead vigorously, has become one of most important leather and the leather goods production center in the world at present.The ox-hide in China, pig
The resources such as skin, sheepskin rank first in the world, and annual light leather yield ranks first in the world, and account for 20% or more of world's total amount, and make
Leather industry is just constantly becoming the distinctive industry in China, and increasingly important role is played in national economy.
Leather processing refers to the rawhide that will be easy to addle, i.e., after series of processes is processed, rawhide just becomes former skin
At the process of leather that is soft and not addling.Usually by former skin to finished leather is made, it is broadly divided into three phases, the preparation stage,
The tanning stage and arrange (ornamenting) stage, mainly contain immersion, fleshing, depilation, liming, degreasing, softening, pickling, tanning and
-- (fleshing) -- weighing -- pre- immersion -- (fleshing) -- weighing -- main leaching that the subsequent arrangement stage, batching can be subdivided by specifically having
Water -- (degreasing) -- depilation, liming -- (fleshing) and/or split -- weighing (multiple ash) -- deliming -- softening -- (washing one's face) -- leaching
Acid-pre- tanning, main tanning and retanning and etc..
As leather pattern and application field are further widened, existing leather not only includes that surface is a kind of special grain
Surface layer, i.e. plate face, with natural graining and gloss, the characteristics of comfortable feel, untreated original skin (pelt) is known as removing from office
Skin also includes leather and fur or double-face leather, refers to leather (hair of the Animal Skin with hair through tanning, the obtained one side of dyeing and finishing with hair
Leather), untreated original skin is also referred to as fur.Fur is made of fleece and dermatotome two parts, and wherein fleece refers to animal
The one side of hair, dermatotome is then the surface with natural graining and gloss.
However for fur, due to the structure that its special fleece and dermatotome two parts are constituted, in treatment process
In terms of with biggish difficulty, especially dyeing effect, although carrying out dyeing processing to leather has more mature technology, mesh
Preceding that dyeing processing is carried out on fur product, especially dye black also still remains many problems, this is primarily due to fur product
It needs hair plates to take into account when dyeing to account for, should guarantee fleece blackness, good dry and wet wipes effect again.
And the conventional black process flow of dye are as follows: retanning-dye hair-dye plate-fixation.The technique has problems in that, dyestuff
Dosage is big, and dyestuff absorptivity is low, and then causes blackness low, and a large amount of dyestuffs are remained in dyeing waste-water；And finished product Bearable dry and wet wipe jail
Spend difference etc..
Thus, a kind of dye black-labour skill of fur preferably how is obtained, especially for the black technology of dye of hair leather vamp,
As numerous production firm's urgent problems to be solved in the industry.
Summary of the invention
In view of this, the present invention provides the technical problem to be solved in the present invention is that providing a kind of dye black-labour skill of fur
Fur dye black-labour skill, can reduce dye dosage, improve dyestuff absorptivity, to improve blackness, reduce in dyeing waste-water
Remaining dyestuff, moreover it is possible to improve the Bearable dry and wet wipe fastness of finished product.

Referring to Fig. 1, Fig. 1 is the general flow chart of the dye black-labour skill of fur provided by the invention.
The present invention carries out at normal temperature for dye plate traditionally, although avoiding hair on dye plate, dry and wet is caused to be wiped
Low problem.The process flow that this technique is bathed altogether using high temperature dye plate+retanning fixation+high temperature dye plate dye hair, high temperature improve dye
The infiltration and combination activity of material, substantially increase the absorptivity of dyestuff, color is more pitch-black, full.In order to solve on dye plate
It the problem of hair, after dyeing, further uses suitable sodium hydrosulfite and hair side is gently floated, removal remains on hair side
Sodium hydrosulfite, thus the problem for avoiding fleece Bearable dry and wet wipe bad.
Dyeing is complicated physics, a chemical process.After chrome leather anion retanning agent retanning, surface positive electricity is removed from office
Lotus decline, negative electrical charge increases, when then being dyed with anionic dye, then its surface not easy coloring, especially dye Black Leather surface
Whiting or burnt hair.This is a competitive reaction, and first retanning is then not easy to surface coloring；It first dyes, then retanning decreased effectiveness.This
Invention is based on this, using following technology path: dye plate-chrome retanned-dye plate+dye hair-fixation-cleaning, and dye plate is carried out in two times, imitated
Fruit is obviously better than traditional dye black-labour skill, and uniform coloring, tone are full, pitch black degree is high, the absorption rate of dyestuff is high.Substep contaminates
Color carries out emphatically padding based on first time dyeing for the second time.It to contaminate for the first time, want full for the second time.
Present invention is particularly suitable for hair leather vamp high-selenium corns to contaminate black technology, by dyes selection and replacement, contaminates black-labour skill
Rationally setting, color fixing agent selection and use.By Thinking Creation and experimental summary, each key point technology is carried out best excellent
Change, and combine, to realize that the reduction of dye dosage uses, Bearable dry and wet wipe color fastness is substantially improved.Experiment knot
Fruit shows the dye black-labour skill using fur provided by the invention, plate dye dosage 7.5g/L is contaminated, far below the 12g/ of traditional handicraft
The dosage of L, and product blackness is good, meets customer requirement；Xerotripsis grade is 3.0, and wet rubbing grade is 2.0.
In order to further illustrate the present invention, with reference to embodiments to a kind of dye black-labour skill of fur provided by the invention into
Row detailed description, but it is to be understood that these embodiments are to be implemented under the premise of the technical scheme of the present invention, are given
