What is pressed leather?
Pressed leather is not leather, but leatherette! How is it made? Leather scraps, sawdust, shavings and dust are mixed, all this is subjected to special chemical treatment with various compounds and the resulting mass is glued under pressure and under the influence of a certain temperature.
First of all, people who are far from understanding the specifics of creating leather products need to understand one important point – no matter how the version of leatherette is called and produced, it will never be compared with natural material in quality.
Today, many people think that products made from eco-leather or pressed leather are made from a natural product, they just use special technologies. In fact, everything is not so at all! Pressed leather production:
As noted above, the components of “pressed leather” are trimmings and shreds, shavings, leather dust and other waste remaining after the production and cutting of natural leather, and even secondary waste of the “pressed” leather itself. On the granulator, all this waste from natural hides chopped into small pieces, then everything is mixed.
Next, the second component is added – synthetic binder fibers made of synthetic materials: polyester, polyamide, polyethylene.
When heated, they melt and stick together. The third chemical component is synthetic thermoplastic resins – they are introduced for additional bonding and strengthening of the fibrous structure.
The resulting mixture is then pressed to form a flat sheet. The sheet is sent to the furnace, where chemical processes take place under the influence of heat, then the layer is pressed again. The resin melts and holds the fibrous structure together. After cooling, the sheet is painted with special paints and decorated with embossing.
The result is a matter similar to leather, which is called pressed leather. It must be remembered that Genuine leather is made only from a single piece of skin!
Methods for determining pressed leather
Determining authenticity, it is necessary to look at the reverse side of the skin – Bakhtarma. In natural leather, Bakhtarma has a different structure. On one skin, it can have a long and short pile at the same time, the finger effect always remains (that is, you can draw on it with your finger and the pile will lean in different directions), and various intravital defects and scratches can also be observed on the wrong side. Pressed leather, on the contrary , pile over the entire surface is the same and uniform.
To determine what material is in front of you, you can also look at the skin section. Genuine leather is uniform. The pressed leather on the cut will have a border between the base and the top coat. The surface of genuine leather will differ in different parts of the product.
Somewhere the picture will be larger, somewhere smaller. The surface of the pressed leather is homogeneous everywhere, the same, the pattern of the material is of the same type, without visible differences. Testing leather with an open flame will not always give a result, since now special additives are widely used to prevent open burning, and pressed leather will sometimes smolder, like genuine leather, which will not give you an understanding of what is in front of you in the end.
We describe the main differences between natural material and its surrogate.
Place your hand on the product for 30-40 seconds. The warmth of the hand is instantly transferred to the natural material and remains for some time, while the skin remains dry. The surface of the substitute heats up slowly, and a greenhouse effect forms between it and the palm.
Softness and elasticity
A leather thing does not stretch well, but it does it in all directions! Pressed leather drapes well, but if it is slightly stretched, it stretches according to the principle of any fabric: it is good along the transverse threads and badly along the longitudinal ones.
The animal’s skin is pierced with pores that allow it to breathe. Small holes are located randomly, they can be seen with a magnifying glass. New technologies make it possible to imitate even this feature of natural material, but a close examination with a magnifying glass reveals that these punctures have a repeating pattern.
A simple test will help determine the skin from a substitute: bend the fabric and evaluate the shade of the fold. If it has not changed, but at the same time remains a hall, you have leatherette or pressed leather in front of you. If it brightens slightly, but gradually straightens without traces, the skin is real.
Inexpensive analogues of natural material have a characteristic synthetic smell, which makes it easy to identify a substitute. But manufacturers who want to sell the product at a higher price use flavors and fragrances that give synthetics a smell similar to genuine leather!
You can check the naturalness of the leather with water (only aniline treatment will give the result!, without coating with varnishes and paints!) – The leather item will absorb moisture and change color. This will not happen with semi-aniline, pigmented, and artificial polyurethane material. In this way, mainly sheepskin coats and jackets are checked for authenticity.
Bring a lit lighter to the fabric for a few seconds: there will be no trace left on the leather item, it will not deform. A scorched mark may appear on synthetics, and a characteristic smell will be released. If the fire is held longer, the leather copy will begin to smolder, the pressed leather forms ashes during combustion. Only premium quality in our ANGEL LB store!
