Imitation leather

Imitation leather (also: imitation leather, imitation leather, skai) is an imitation of leather that consists of a plastic that is applied to a textile carrier. A drawing and structure

that resembles the structure of a type of leather is printed in the plastic. Artificial leather is used for chairs, sofas, handbags, coats and shoes. One of the great advantages is that it does not absorb or transmit moisture. This is important when it is applied in clothing or shoes.


Polyester is spun into filament by melt spinning. For applications in the clothing sector, polyester is also sold as a partly oriented yarn (POY). The yarn is then only pre-stretched and then fully stretched and usually textured in the same step.

Polyesters melt before they burn. The flame is clearly sooty and a hard, brown ball remains. The fibers / threads burn with a sweet smell and extinguish when the flame is removed. The melting temperature is around 255 ° C. The heat resistance of polyester is thus better than that of polyamide 6 and approximately equal to polyamide 6.6.

The elastic modulus is higher than that of polyamide. Polyester is therefore very suitable as an admixture in fabrics that must not be wrinkled and whose shape must be retained. Polyester absorbs virtually no moisture in a normal climate. The percentage is only 0.4%. Polyester is highly resistant to acids, oxidizing agents and diluted lyes. It is less resistant to warm, concentrated lye. Polyester is resistant to sunlight. It is therefore often used for net curtains. Bacteria and fungi do not attack the threads
