Abstract
The invention relates to a production process for leather for painting. The modern leather picture does not adopt the advanced production process for leather products, has a poor manufacturing method, a complex manufacturing process and single style, has no storage stability, and has high possibility of fading. The leather for painting is prepared by the steps of soaking in water, removing meat, degreasing, liming and removing hair, removing lime, softening, soaking in acid, tanning, extracting alkali after tanning, drying, painting, coating, shaping, mounting and obtaining the finished product, so that the leather has storage stability and is not damaged by worms when being placed for a long time. Painting adopts different painting methods of Chinese painting and oil painting, so that different styles are shown. The leather subjected to painting is treated, so the leather is anti-oxidant and is not faded along with the time. Chromium is not used in the tanning process, so environmental pollution is little.
Description
Technical field
The present invention relates to a kind of Process for producing leather, be specifically related to a kind of the drawing with the production technique of leather.
Background technology
Skin is drawn a kind of artwork that artistic value is arranged very much that (having another name called the skin carve and paint) is the people of Mongols invention.Skin is being decorated with very long history, and the origin that skin is drawn can be traced back to pastoral stage, and is the most common with sheepskin map, simple decoration painting.Modern Mongolian skin is drawn except that keeping simple and unsophisticated charm, dissolves in modern nationality's skill and technique more, need form such as colored paint, painted, pure making by hand of tens procedures such as layer dyes, polishing, typing, embossment convex-concave.The skin picture makes full use of and has showed that natural leather has characteristics such as the lines flow smoothly, the structure tracing is unique, stereoscopic sensation is strong, color is soft, gives brand-new artistic treat.
It is to have making a present and upholstery of reserve value and enjoying value that skin is drawn.The artistic level that skin is drawn is very high, and it makes full use of and has showed the cortex color of the leather that natural leather had, and has characteristics such as the lines flow smoothly, and the structure tracing is unique, and stereoscopic sensation is strong, and color is soft, gives brand-new artistic treat.Even but modern skin draws and still to adopt advanced leather goods production technique, manufacture technique falls behind, complex manufacturing technology, single, the not anti-storage of style and fade easily.
Along with development of science and technology, and though modern leather on working method or the resultant leather quality all than very big leap was arranged in the past.But the skin painting making technology still rests on the method in the past, produces skin with the mode of producing handicraft and draws, and soon leather is cut into small pieces and is attached on the drawing board; Adopt manual process then; Spray paint, operation such as polishing, making method is very complicated, production efficiency is low; The attractive in appearance and integrity of drawing is not more suitable for this name of skin carve and paint in fact.
At first be not have to be fit to the Process for producing leather of directly on leather, painting in the reason of directly drawing a picture on the hide, such leather is not only wanted the whiteness height, and the thickness difference at each position and pliability are low, and the degree of packing is very high; Next is direct drawing back pigment fugitive color on leather, store after for some time pigment oxidized easily and variable color takes place, phenomenon such as fade, reduce skin image quality amount greatly.
Summary of the invention
The purpose of this invention is to provide simple, anti-storage of a kind of technology and drawing not easy to fade production technique with leather.
The technical scheme that the present invention adopted is:
A kind of drawing with the production technique of leather is characterized in that:
Realize by following steps:
Step 1: immersion:
Place its quality 2-6 30-35 ℃ of immersion liquid discontinuous doubly to rotate 12-24h hide;
Step 2: fleshing:
Hide after the immersion of immersion liquid is carried out mechanical fleshing to be handled;
Step 3: degreasing:
Hide behind the fleshing is placed its quality 2-6 35-40 ℃ of degreasing fluid doubly, intermittently rotate 1-4h;
Step 4: liming depilation:
Hide after the degreasing is placed its quality 1-3 35-40 ℃ of liming liquid doubly, intermittently rotate 12-24h;
Step 5: deliming:
Hide after the liming is placed its quality 0.5-2 25-35 ℃ of deliming liquid doubly, intermittently rotate 1-4h;
Step 6: softening:
Hide behind the deliming is placed its quality 1-3 25-35 ℃ of bating liquor doubly, intermittently rotate 1-4h;
Step 7: pickling:
Hide behind the deliming is placed its quality 1-3 25-35 ℃ of pickling liquid doubly, intermittently rotate 1-4h;
Step 8: tanning:
In pickling liquid, add tanning agent and carry out tanning, tanning time 2-6h;
Step 9: carry alkali after the tanning:
The sodium bicarbonate that in tanned liquid, adds tare weight 1%-10% is carried alkali, carries alkali time 1-5h, leaves standstill 12-24h after carrying alkali;
Step 10: drying:
The stretching shady and cool place of the method Air drying that leather behind the alkali uses toggling is carried in tanning, time of drying 12-36h;
Step 11: drawing:
Hide behind the finish-drying is carried out deburring, make hide edge uniformity, directly on hide, paint then;
Step 12: cover with paint, lacquer, colour wash, etc.:
Carry out polished finish after fully drying Deng pigment, make the color and luster of drawing more bright;
Step 11: typing:
With the crust leather excess pressure roller after covering with paint, lacquer, colour wash, etc., it is more firm that its coating and decorating material is combined;
Step 12: mounting:
Crust leather mounting after the ironing in photo frame, is obtained finished product.
In the step 1, comprise the chlorinated lime that accounts for tare weight 0.1%-0.5%, the soda ash of 1%-5%, the grease-removing agent of 0.1%-1.0%, the soaking enzyme of 0.1%-0.5%, the immersion auxiliary agent of 1%-5% in the described immersion liquid.
