Abstract
A method and apparatus for the thermal treatment of textile articles in which a moving yarn is delivered from a yarn supply and a main thermal treatment is carried out in a conventional manner by contact with a heated oven, the yarn is cooled and a false twist is applied which feeds back to the main thermal treatment zone. The yarn is then subjected to a further heat treatment and the untwisted yarn is rewound. The yarn is subjected to a complementary heat treatment before and/or after the main thermal treatment by wetting the yarn and then heating it by high frequency heating.
