Polyester fibres belong to the group of polymers and when further processed they are now among the most popular synthetic fibres in the textile industry. Originally polyester was developed as an alternative to silk, but as a microfibre polyester fibres can be up to three times thinner than silk fibres. Nowadays, they are developed and processed in a wide variety of strengths.
The properties of polyester fibres include their tear resistance and ease of care. They hardly absorb moisture due to their low pore density and ensure that moisture can evaporate quickly.
Polyester fibres are often used as blended fabrics, for example as a cotton-polyester blend.
