The crease displacement and the achievable dilution factor in the conventional continuous pretreatment or aftertreatment operations of fabric ropes with liquid means in rope washers are not adequate, and consequently the water consumption necessary for satisfactory results is too high. To date the existing problems can only be solved with squeeze rollers which, however, have an adverse effect on the goods. According to the invention the textile rope is now introduced into a treatment store of a liquid-operated jet apparatus, is subjected to the action of the treatment liquor, is then carried along by a steam- or more generally gas-operated jet arrangement and conveyed into an interim store, where dewatering takes place. From the interim store the goods, with satisfactory dilution factor, are then passed to the next isothermal or non-isothermal treatment stage of the same or a very similar structure.
A process for treating textile woven or knitted fabric rope guided through jet apparatus during the continuous passage of the rope through various successive but separate wet-treatment zones of the apparatus, the process comprising the steps of supplying a treatment liquor to the textile rope entering a wet-treatment zone as the rope passes through a liquid-operated jet arranged to move the rope along its path of travel, simultaneously forcing the rope into an immediately following storage space filled with the same treatment liquid, where the continuously moving rope is subjected to the action of the treatment liquid, continuously removing the textile rope thus wet-treated from the storage space by a downstream steam- or gas-operated jet, and feeding the rope into a subsequent interim store where the continuously moving rope is largely freed of the previously applied treatment liquid.
An apparatus for treating textile woven or knitted fabric rope comprising a liquid-operated jet arranged to receive and move the rope along its path of travel, an immediately following storage space holding treatment liquor and arranged to receive the passing textile rope, a steam- or gas-operated jet arranged downstream of the storage space to receive and move the rope along its path of travel, and an interim store directly downstream from the steam- or gas-operated jet for receiving the textile rope and freeing the rope of the previously applied treatment liquid.
