The method of obtaining three-dimensional pattern on the front surface of the pig skin using elektrovyzhigatelem device
(57) Abstract:The method relates to light industry, namely, leather goods, footwear industry, producing clothing as decoration, and art crafts. This method retrieve the image on the front surface of the skin allows you to combine modern production of leather goods with folk traditions, thereby folk art and, in particular, folk crafts from the field of decorative-applied art are moving into the area of production of consumer goods with improved aesthetic and performance properties, is expanding the range of manufactured from pig skin products. Another important advantage of this method is the possibility of using the skin with minor marriage front surface and allow the fat content in the skin, and to regulate it yourself. For regulating the fat content in the skin, you must first wet the front surface of the pig skin, but after 10 minutes, apply Shoe cream the required color. Next put a figure on the obverse surface of the skin with the edge of the knife using a stencil and burn the resulting line in the example is abayat Shoe cream thereby fix the resulting image. Then perform a cut on the obtained drawing on a depth of 0.1 to 0.2 mm are repeated burning figure in the direction opposite to the incision. Again to secure the figure it is treated with Shoe cream. Next highlight the contrast of the figure, the dashed movements of the needle apparatus for burning, thus creating a difference in color, and receiving three-dimensional image. In conclusion, put Shoe Polish for the final fastening of the picture and give it elasticity. During operation visual difference between processed by burning and raw plots of figure increases over time. The dark surface becomes darker, and the light is brighter and the picture becomes sharper and bigger. This is the main advantage of this method is conducive to the longevity of use of the product while maintaining the product. 5 Il. The invention relates to light industry, namely, leather goods, footwear industry, producing clothing as decoration, and art crafts.Analogue of the invention is a method techniques of burning, CLASS="ptx2">On the skin by working drawing put the sketch. First needle apparatus for burning issue main line, then details. The desired texture of the surface can be achieved using lines, points. When the burning need to check the temperature on a separate piece of skin. The desired temperature depends on the fat content in the skin. Because the skin quickly burn, it's impossible to use too hot needle and push on the skin. You need to work quickly and smoothly. The needle should not on the skin to stop. The work requires a steady hand.In conclusion, the leather is dyed with synthetic dyes, mixed with a small solution of acrylic paint, tempera, markers, etc. to Paint carefully. You cannot wet paint line burning (see Technology artistic leather goods, CULV E. P., Kirma K. K., Rama H. K. Summatavet E. G., Light and food industries, 1982, S. 129).The closest analogue of the claimed invention is a method of obtaining three-dimensional pattern on the front surface of the pig skin, which consists in the fact that the figure put on the facial skin surface using a stencil and burn the resulting line drawing using for burning (the book of Anninou T. C., Artistic leather goods, M, Russian peoples friendship University, 1994, S. 24-26, 74-75, 77-82).The technical result of the claimed invention to provide a new range of competitive products with high quality from the point of view of the aesthetic needs for appearance and superior performance characteristics and provides a new direction of art processing the front surface of the pig skin.To achieve the technical result of the claimed invention is that the image is applied on the front surface of the pig skin using a stencil and burn the resulting line drawing by means of the apparatus for burning, perform allocations contrasting parts of the drawing stroke movements of the needle apparatus for burning, and before patterning first moisturize the facial skin surface with the subsequent implementation of aging for 10 minutes, then applied to the front surface of the Shoe cream desired color, and then drawing on the front surface is performed with the blade of a knife, burning these lines is carried out in the direction opposite to the drawing, then the drawing,nomu drawing for a thickness of 0.1 to 0.2 mm and are repeated burning figure in the direction opposite the incision, and again put Shoe Polish for fixing the drawing, in conclusion, put Shoe Polish for the final fixing of the image.In Fig. 1-5 depicts the drawings on the skin.The claimed method differs from the closest that you can use the raw material is not depending on the fat content in the skin, and by using appropriate processing to adjust its content in the use of raw pork skin. The picture painted is not needle apparatus or a pencil and a sharp knife with direct cutting of the front surface of the skin. Also for drawing figure is not used to drawing and stencils of different configurations, which can be applied is not the whole picture at once, but gradually, layer by layer. Thus manages to reach the volume of the resulting figure, which allows to improve the performance properties of the product and increases its service life.Staining of the skin dyes is not after all operations, and before that promotes fixation of the resulting colors in the product.The invention is reduced to a serial execution of some operations.First moisturize the facial surface of the pig skin with p is th the cream of the required color. Next, drawing on the obverse surface of the skin carry a sharp knife using a stencil. Burns received a line using the apparatus for burning in a direction opposite to the drawing figure, then the figure obtained by burning, handle Shoe cream to secure it. Next, perform an incision on the obtained drawing on the thickness of 0.1-0.2 mm and are repeated burning figure in the direction opposite to the notch, and again put Shoe Polish for fixing the picture, then highlight the contrast of the figure, the dashed movements of the needle apparatus for burning, in conclusion, put Shoe Polish for the final fixing of the image.Currently, when the organization of any production requires large investments, such an outdated concept as manual work becomes not only an aesthetic but also a new economic sense. The claimed invention allows to avoid high material costs for the purchase of equipment, payment of energy and the use of foreign technology gives you the ability to organize a large number of jobs, thus partially solving the problem of rising unemployment. Also given is the front surface defects, thus makes it possible to reduce the number of defects and waste in the leather industry. The use of the claimed method allows not only to improve the appearance of products, but also to use such basic quality pigskin as durability and wear resistance. The main disadvantage of pig skin has always been that after brief use of the products, they began to zaselyatsya and shiny, thus quickly losing marketable products while maintaining performance properties. Extend the use of the product allows this method, excluding the occurrence of defects during operation of the product. This is ensured by the fact that the visual difference between processed by burning and raw plots of figure increases over time, the dark surface becomes darker, and the light is brighter, the picture becomes sharper and bigger.The flexibility of this method allows us to strictly follow the requirements of a constantly changing fashion by changing the product shape and pattern.The range of decoration products unlimited - this method allows you to migrate any existing pattern on the skin.

FIELD: leather industry.
SUBSTANCE: preparation of composition is conducted on vertical-type bead mill. Induline, kerosene, and diesel fuel are consecutively charged into mill before stirring mechanism is energized, after which apparatus and contents thereof are slowly heated. Stirring is then stopped for 1 h while slow heating of mill contents is continued. When specified time expires, carboxylic acid or acid mixture, white spirit, fat additive, and aluminum oxide or hydroxide are added. Mechanic stirring is then switched on and contents of the bead mill are ground and the process is carried out at spontaneously fixed temperature caused by heat effects of the processes and natural cooling. When temperature is lowered to 85-120°C, desired product is discharged.
