Abstract
An elongate textile material liquid-permeably wound on a bobbin and a treatment liquid are enclosed in a container with a gaseous phase portion remaining within the container. The container is conveyed through an elongate heating bath for heating the treatment liquid at a predetermined temperature. During conveyance, the container is rotated to cause the textile material to move alternately through the treatment liquid and the gaseous phase portion within the container.

A method of treating an elongate textile material with a treatment liquid, comprising the steps of:
- (a) sealingly holding in a container an elongate textile material to be treated which is liquid-permeably wound on a bobbin and a treatment liquid while keeping a gaseous phase portion within the container;
- and
- (b) conveying the container longitudinally through an elongate high-temperature treatment zone to heat the treatment liquid at a predetermined temperature while rotating the container together with the bobbin held therein to cause the textile material to move alternately through the treatment liquid and the gaseous phase portion within the container, thereby treating the textile material with the treatment liquid.
An apparatus for treating an elongate textile material with a treatment liquid, comprising:
- (a) a bobbin for winding thereon an elongate textile material and having a liquid-permeable structure;
- (b) a container for sealingly holding therein said bobbin and a treatment liquid with a gaseous phase portion kept within said container, said bobbin being immovably held within said container;
- (c) means defining an elongate high-temperature treatment zone;
- (d) a conveyor device for conveying said container longitudinally through said elongate high-temperature zone for heating said treatment liquid at a predetermined temperature;
- and
- (e) a rotating device for rotating the container to cause the textile material to move alternately through said treatment liquid and said gaseous phase portion while said container is being conveyed by said conveyor device.
