Description
Technical field
The invention belongs to leather processing technical field, it is related at a kind of finishing agent, comprehensive Coating technology and wet blue
Science and engineering skill more particularly to a kind of finishing agent for abortive calfskin, the synthesis Coating technology for abortive calfskin and for abortive calfskin
Wet blue treatment process.
Background technology
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 into 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.
As leather pattern and application field are further widened, existing leather includes not only that surface is a kind of special grain
Face layer, i.e. plate face, with natural graining and gloss, the characteristics of comfortable feel, untreated raw hide (pelt) is known as removing from office
Skin also includes leather and fur or double-face leather, refers to the Animal Skin with hair through tanning, leather of the obtained one side of dyeing and finishing with hair,
Untreated raw hide is also referred to as fur.Fur is made of fleece and dermatotome two parts, and wherein fleece refers to one with animal wool
Face, dermatotome are then the surfaces for having natural graining and gloss.
Leather processing refers to the rawhide that will be easy to addle, i.e. after series of processes is processed, rawhide just becomes raw hide
At the process of leather that is soft and not addling.Usually by raw hide to finished leather is made, it is broadly divided into three phases, the preparation stage,
Tanning stage and fin-ishing stages, mainly contain immersion, fleshing, depilation, liming, degreasing, softening, pickling, tanning, neutralization, filling,
Stuffing, dyeing and subsequent fin-ishing stages.Among these, most start to be taken off the skin to get off and be commonly referred to as fur, also referred to as rawhide,
And it is deoiled with lime, akali sulphide, chlorine powder, nitric acid and chromium powder etc., can be in indigo plant after degreasing, depilation and first time tanning processing
Color, and carry moisture, commonly referred to as wet blue, also known as bark.
In the production technology of current abortive calfskin, at present mainly based on plane, the production of contracting line class abortive calfskin product
Process it is relatively fewer, production and processing generally pass through two ways：First, tempering, then uses aldehyde product under the conditions of high pH value
By the quick in conjunction with realizing contracting line of surface, but tempering risk is big and the lines size that contracts is uneven, elastic with hide
Degree has much relations, is unfavorable for controlling；Second is that leather color embryo falls soft to fall by heat, pass through temperature, humidity and time
Control come contracting branching, but it is this under the conditions of scytoblastema is handled consistency requirement it is very high, the line that otherwise contracts not only open with
It is widely different between, and the different parts of same skin also will appear lines situation not of uniform size, and production is difficult to control.
Thus, a kind for the treatment of process of contracting line class abortive calfskin production preferably how is obtained, is solved in above-mentioned production process
There are the problem of, it has also become numerous production firms and many line researcher's urgent problems to be solved in the industry.
