Abstract: A dyeing apparatus (10) is described which is provided with a single tank (12) comprising: side walls (14); a bottom wall (16), which has a convex outer surface; a first inner partition wall (18) and a second inner partition wall (20), which delimit a dyeing compartment (26) and define respectively a first interspace (28) and a second interspace (30); and at least one mobile and/or removable upper lid (32), which closes the dyeing compartment in a watertight sealed manner. A first hydraulic circuit (34, 36; 38, 40) is designed for circulation of a first process fluid (B), whereas a second fluid circuit (42) is designed for circulation of a second process fluid (N). The first hydraulic circuit comprises first means (34, 36) for entry/exit of the first process fluid, which are designed to feed the first process fluid up to a first predefined filling level (L1) both in the dyeing compartment and in the interspaces, and second means (38, 40) for entry/exit of the first process fluid, which are designed to feed the first process fluid up to a second predefined filling level (L2) both in the dyeing compartment and in the interspaces. The second distance (D2) is greater than the first distance (D1), so that the second predefined filling level (L2) is greater than the first predefined filling level (L1).

Abstract: A dyeing machine comprising at least one dyeing module in which a first squeezing device for a textile support, a first treatment tank, a central tank, a second treatment tank and a second squeezing device are located in sequence is described. The dyeing machine also includes a hydraulic system for feeding, circulating and alternately adjusting the levels of process fluids in the tanks. The tanks are preferably enclosed in a hermetically sealed upper covering shell. The two treatment tanks have the same shape, the same dimension and capacity characteristics, and are symmetrical with respect to a plane of symmetry lying in the central tank and arranged perpendicularly with respect to the direction of advance of the textile support. The dyeing machine is provided with means for moving the textile support, configured to advance the textile support alternately in both directions, i.e. either from the first squeezing device to the second squeezing device, sequentially through the tanks, or from the second squeezing device to the first squeezing device, again sequentially through the tanks.

Abstract: The invention relates to a tank for washing a warp thread, provided with a device for intensifying the washing effect set in rotation inside the tank. Each device includes a body having cylindrical geometry, having circular cross section, which has a plurality of longitudinal bars arranged along the cylindrical side surface of the device. Between each pair of adjacent bars a longitudinal slit is defined. The body also has a pair of end elements extending radially, forming the opposite bases of the body and configured to support and enclose the bars. The body also has a pair of opposite rotation pins, obtained on the respective outer surfaces of the end elements and that extend along an axial direction and parallel to the direction of extension of the bars. The body also has a tangential turbodynamic flow generator, arranged inside the body and configured to intensify the interchange between the washing liquid and the warp thread through the longitudinal slits during the rotation of the device.
