Abstract
A comparative analysis of methods of extracting oiling agent from chemical fibres showed that one extraction in a shaker could be used for all types of fibres investigated. Repeated extraction of the oiling agent using a Soxhlet apparatus can be recommended for all fibres investigated except for polyamide and polypropylene, since other compounds are extracted from these fibres together with the oiling agent.
