Imitation coloring of skins. Simple recipes and tips
Directory / Factory technology at home - simple recipes Here are some recipes imitation skin coloring. Cheap skins, with proper processing and coloring, can look like magnificent furs. Until recently, the methods of dyeing and processing skins were secrets. Previously, dyeing was done with mordants, iron sulfate, chromic, copper sulfate, in combination with pyrogallic acid and a few natural dyes. The introduction of ursols and furrolls into practice greatly simplified production. The strength and the number of shades obtained have also increased. Dyeing of the simplest varieties of animal skins is practiced: hares, cats, dogs and squirrels. The skins of animals are rarely dyed in a single color. Usually, by tinting, they make the fur look like more expensive varieties. This processing is done by hand and requires some skill. In dyeing animal skins come fermented and wrinkled. When using ursols and furrols, the color appears on the fibers after the use of oxidizing agents (potassium manganese salt, sodium perborate, hydrogen peroxide, chromic peak, ferric chloride). The most common brands of these dyes are as follows: Ursol R, Ursol D, Ursol DB and Ursol 2G, Furrol B, Furrol S and Furrol 5B. Of the oxidizing agents, sodium perborate is best used. Sodium perborate is more convenient than hydrogen peroxide because it doesn't degrade as quickly and is cheaper. The degree of strength of the solution is determined depending on the desired shade of color. "Ursol D" and "Ursol DB" give a black coloration. "Ursol D" gives an intense black color, and "Ursol DB" - blue-black. "Ursol 2G" gives a yellowish brown tint. "Ursol R" gives a reddish tint. When combined, they give a good brown tone. "Furrol V" paints in brown tones, "Furrol S" - in a black shade and "Furrol SB" - in gray. Dyeing of animal skins can be done in two ways. According to the first method, the entire skin is immersed in the dye bath. According to the second, the dyeing liquid is brushed onto the hair (pointing). If the skin is rich in fat, then before dyeing it is necessary to treat it with lime or a mixture of lime and soda. It is best to cover the skin on the front side with the following mixture:
The mixture is applied with a brush, after which the skins are dried and washed well. Thanks to this treatment, the hair is freed from fat and becomes more receptive to coloring. For some types of skins, you can use a soda solution with a strength of 6 ° Be. Very oily skins can be treated with a weak solution of caustic soda. If this treatment is not desirable, then degrease the skins in a soap solution, to which you can add a little soda. Treatment with caustic soda should be avoided whenever possible.

Mordant for gray and black tones
The skins are immersed in one of these solutions at a temperature of 38 °C for 2-3 hours, depending on the type of skins being processed. After thorough washing with cold water, the skins go for dyeing, which lasts about 3 hours. Below are some examples of dyeing animal skins. Sable rabbit coloring The long-haired rabbit is painted under. brown sable as follows. The hair is treated with caustic soda with a strength of 2 °Be, then pickled for 3 hours in the following solution:
After pickling, the skin enters the dye solution, which is composed as follows:
First, dissolve all the ursols and pyrogallic acid in 5 liters of water. They take half of the solution obtained in this way and lower the skins into it for 1-2 hours, then pour hydrogen peroxide into the bath and leave the skins in this bath for another 2 hours. After this time, the second half of the remaining used solution is added. The skins remain in the bath to obtain the coloring of the desired shade. During dyeing, in order to avoid uneven coloring, it is necessary to sort out the skins continuously. Processing of hare skins Cheap hare skin can give an imitation of expensive varieties of goods, if you first dye the skin in one tone, and then use a brush to paint the ends of the hair in a different color. For example, the ground is given a dark brown, and the ends of the hair are black or brown-black. In practice, this can be done like this: The skin is subjected to processing (degreasing and pickling), as indicated above, with a composition of lime, iron sulfate and alum using a brush. Then, after rinsing, they are dipped for 6 hours in a chrome pickle, after which the skins are washed and enter the dye bath, composed as follows:
In this solution, the skins remain for 6 hours, after which the following composition is applied to the ends of the hair:
Imitation groundhog under sable The marmot is dyed sable brown in the following way: The marmot skin is degreased as above, treated with a mixture of lime, iron sulfate and alum, followed by bleaching by immersing the skins in a hydrogen peroxide solution (equal parts water and hydrogen peroxide). Next, the skin is immersed in a dye bath, compiled according to the following recipe:
Staining lasts about three hours, after which, with the help of a brush, a tip follows, composed as follows:
Imitation of a rabbit under a cat A sheared rabbit gives an imitation of a cat, for which, after a 6-hour chrome mordant, the skins are immersed in the following bath:
In this bath, the skins remain for 4 hours, after which they are subjected to a tip, consisting of the following composition:
Imitation of a muskrat under a cat To obtain a more expensive imitation of a cat, the desman skin is etched with chromium, and then painted in a bath:
Leave in the bath for 6 hours and subjected to a pickup consisting of the following composition:
Black dyeing of muskrat, ground squirrel, foals and dogs The skins, defatted and finished after fermentation, are placed in a solution obtained by dissolving 1 g of logwood extract and 800 g of turmeric in 400 bucket of hot water. The solution is used cooled to 40 °C, the skins are left in it for 12 hours, the product is allowed to flow around and placed in a pile. Then 1 g of iron sulfate and 600 g of copper sulfate are dissolved in 85 bucket and added to the heated first solution resulting from the previous operation. The skins are loaded into this bath at a temperature of 40 °C for 12 hours, removed from the bath, wrung out and hung for 12 hours. Then the remaining mixture is heated to 40 °C and the skins are immersed there again for an hour. Next, the skins are removed, squeezed and hung for 12 hours, thoroughly washed and dried.
