Estimating the term…
In the textile industry there is a constant need for processes where the textile material to be treated can be treated in a simple form, for example in rope form instead of in the open-width state, and continuously. According to the invention, this need is met when the textile material is introduced via pressure seal elements into a specially constructed jet dyeing machine, is impregnated there with treating liquor during entry or immediately thereafter and is conveyed further in the machine by means of at least one jet operated by means of a gas stream, the treating agent applied, preferably dye, having advantageously been subjected to fixation in the course of the presence in the gas atmosphere. The necessary physical conditions (pressure, temperature) for this are created by the driving gas. Moreover, in the course of the passage of the textile material it is possible to carry out a further, including a completely different, impregnation.
A process for continuously treating textile material made of synthetic and/or natural fibers in continuous loop rope form with an aqueous liquor containing at least one treating agent on a jet dyeing machine having a self-contained treatment zone and a recirculating gas stream generated by actuation of a jet system, the kinetic energy of which provides the propulsive force for continuously transporting the textile material spirally through the self-contained treatment zone, comprising the steps of continuously introducing the textile material into the self-contained treatment zone through a sealing inlet thereof, impregnating the textile material with the aqueous liquor in the course of its passage through the treatment zone, conveying the textile material forward through the treatment zone by means of the circulating gas stream via an aerodynamically active jet arrangement comprising at least one transport jet, allowing the textile material to dwell under conditions capable of being effective for the treating agent towards the textile material in the treatment zone up to 20 minutes, and transporting the textile material out of the treatment zone through a sealing outlet thereof.
