Abstract
The invention relates to the wet processing in particular of knitted tubular material in the broad tubular state which in a first processing section is led through a fluid bath then inflated to form a balloon section and afterwards led in the broad tubular state through the gap between a pair of squeezer rollers. Within the fluid bath the incoming material in hank form is subjected to twist sensing and if any twist is detected the incoming tubular material is rotated in the region before the first processing section to undo the twist. The completely and stably relaxed and untwisted tubular material leaves this first processing section in a stable broad tubular state and can then be passed in an optimum manner through the succeeding principal processing sections.
Claims7
A method of wet processing tubular textile material in the broad tubular state comprising the steps of:
- (a) wetting the material in a fluid bath located in a first processing section;
- (b) sensing any twists in the material after the material has been wetted inthe fluid bath by means of a sensing apparatus;
- (c) rotating the material upstream of the fluid bath to relieve any twisting sensed in the material by the sensing apparatus, the amount of rotation being controlled in proportion to the degree of twisting sensed by the sensing apparatus;
- and
- (d) further processing the textile material after the step of sensing any twist in the material by
- (i) blowing gas into the material downstream of the fluid bath to form a ballon section for inflating the material into a broad tubular state;
- (ii) passing the material after it has had gas blown into it through a gap between a pair of squeeze rollers;
- and
- (iii) storing the material in a storage zone after it has been passed between the squeezer rollers.
