Abstract

Polyester fibres are the mostly used synthetic fibres in textile industry. As the majority of polyester in commercial terms, polyethylene terephthalate (PET) is generally dyed at 130°C. High-pressurised dyeing equipment and excessive energy are required to achieve the high temperature for dyeing. The high temperature also limits the dyeing of blend fabrics with fibres unstable to high temperature, such as wool. Polylactic acid (PLA) fibres show strength loss after high temperature dyeing due to the hydrolysis of the fibre. Low temperature dyeing for polyester was carried out with carriers or additional process, which increases the production costs. Therefore, it is beneficial to carry out low temperature dyeing of polyester fibres without additional surfactant of process.
