Fundamentals of color science.

Sheepskin coats of different colors and shades.

Light is electromagnetic waves.

The color varies in wavelength.

The scale of electromagnetic oscillations.

Part of the scale is visible light.

Decomposed white light is a spectrum.

Three zones of the spectrum.

White, gray and black colors form a chromatic group that is not decomposed into tones.

All the colors of the spectrum make up a chromatic group, decomposed into tones.

In fact, we see only those rays that are reflected from the product.

Correctly selected colors are the basis of beautiful colors, pure tones.

Before painting, the product is inspected, defects are detected, and cleaned of impurities.

Fur products are loaded into the machine.

Processing-cleaning is carried out in a two-step way in the medium of perchloroethylene.

Perchloroethylene is poisonous and volatile, you need to be careful.

In the first bath for 2 minutes.the solvent acts with a liquid module of 1 to 10.

In the second bath with a liquid module 1 to 15, cleaning is carried out for 6 minutes, with constant solvent filtration and the addition of the greasing agent Avylene 1, at the rate of 80-100 gr. per liter.

At the next stage of preparing the product for dyeing, the product is wetted with a solution of synthanol or synthamide 5.

All preparation operations take place at a temperature of 35-37 degrees.

After the solution is drained from the bathroom, the product is washed with water for 15-20 minutes.

Then lightly squeeze.

On the laboratory assistant's desk there are paints for leather and fur.

All containers with dyes should have stickers with information.

Neutralization-dyeing of fur in the workshop.

Dyeing of products is carried out in dyeing barges.

The dyeing barges in the workshop are placed at a distance of at least 2 meters from each other.

The floor in the workshop must be resistant to acids, alkalis, hot water and non-slip.

Wooden floor grilles.

When loading toxic substances, respirators are used.

The process of neutralization of fur products.

After this operation, a dye is added to the bark.

Add glacial acetic acid.

After the end of dyeing, 2 washings are carried out.

The first using detergent, the second with clean water.

During the dyeing process, fats and salts are washed out of the skin tissue.

They are replenished by adding a fat emulsion and a solution of table salt to the barge.

Pressing of products.

Drying of products on hangers.

Drying chambers.

Supply and exhaust ventilation in the shop.

The process of splitting and rolling back fur products.

This process is carried out in rolling drums with foam sponges, where the leather fabric softens and the pile rises.

Painted products.

Aerosol dyeing.

The product is pre-treated with surface-active substances of wetting action.

Preparation of dyes.

Painting of the product with an aerosol installation.

To obtain a uniform color, the product is dyed three times.

At the final finishing, the product is covered with a greasing emulsion.

The aerosol painting method can only be used in special chambers with exhaust devices.

Fire-fighting poster.

The product is dried in special drums with foam sponges.
