Artificial Leather Definition
Leatherette is a polymeric material used instead of genuine leather. Examples of leatherette are: dermatin, polyvinyl chloride, tarpaulin, polyurethane, etc.
What are they made of?
A more sophisticated technique is used for the manufacture of leatherette using the portable method. Here, vinyl layers are applied to a preparatory paper base having a relief structure, and then a textile backing.
Next, the paper web is removed from the workpiece and placed in a special drying machine, where all layers are finally bonded to each other.
Reference! Other production methods are also used: lamination and lamination.
How to do it yourself?
Selection of the basis (fleecy part)
Knitwear
Leatherette and at the same time durable are leather substitutes made on a knitted substrate. They have heat-shielding properties. Such artificial leather is often used in the manufacture of gloves or outerwear.
the cloth
Durable and dense materials are used for the production of fabric-based leather substitutes. They are quite expensive and have low extensibility. In the manufacturing process, the risk of marriage is likely to occur, which affects the quality of the product during wear.
Non woven backing
As part of such a fabric, like fabrics, there are threads. Only they are not intertwined, but are connected by special protective impregnations. Such a canvas is most often used in the manufacture of leatherette.
Paper
Such a material will have low strength, lack of extensibility and high wettability.
Selection of the upper polymer layer (depending on the purpose of the skin)
Polyurethane (PU)
This polymer gives the product strength characteristics and increased ductility. PU has high resistance to high and low temperatures, as well as hygroscopicity.
It is very difficult to distinguish polyurethane from other non-natural materials. Externally, PU is very similar to genuine leather and does not have a smell, unlike PVC.
Polyvinyl chloride
It is obtained as a result of the synthesis of vinyl chloride. It is not hygroscopic and not frost-resistant, has an unpleasant odor. The positive properties include:
- resistance to chemical compounds (acids, alkalis, solvents);
- does not burn when interacting with air;
- low cost.
IMPORTANT! Many manufacturers make multi-layer leatherette. If the seller proves that you have polyurethane, but the product smells unpleasant, you can be sure that there is a polyvinyl chloride sheet under the PU layer.
Finishing, fastening
Reference! Using various dyes, they achieve any shades that imitate animal skins. The result is a plain or multi-color canvas.
Conclusion
Thanks to artificial substitutes, mankind has solved the problem of a shortage of natural materials. Complex technological processes, various additives eliminate various imperfections in leatherette, increase their strength and softness. Things from them turn out practical and universal in the process of wearing.
