Abstract
For the treatment, especially the dyeing of fabrics, a container is illustrated, which is subdivided into at least two compartments, and is provided, above the compartments, with a motor-driven winch, the direction of which is reversible. The fabric, which can be in rope form, or in open-width form, runs on the winch, and is moved thereby in combination with a system of or nozzles, which spray the dyeing bath onto the fabric. The fabric is anchored on each end at spaced locations in the container which are substantially opposite to each other, in the container area above the compartments, and is made alternately moveable, gathering from either of the compartments into the other one.
Claims25
Process for the batchwise treatment of fabrics, wherein the fabric is treated inside a treatment container by being collected from one stationary part of the container and being laid down in another part of the container, and undergoes the action of a treatment fluid during its movement inside the container, comprising keeping the respective fabric ends inside respective parts of the container, providing driven transport means having a stationary tangential substantially vertical fabric delivery on respective sides thereof in combination with a stationary nozzle substantially vertically below each respective delivery above each of said respective parts of said container for treating said fabric with fluid, alternately gathering said fabric inside said one, and said another part of the container, with said fabric being treated during said gathering from said one part to said another part of the container including lifting the fabric substantially vertically from said one stationary part of the container by passing the fabric about said transport means which turns alternately in opposite directions, and laying down the fabric substantially vertically in said another stationary part of the container.
Machine for treating fabrics comprising:
- a treatment container having at least two stationary parts;
- a winch rotatable about a stationary axis over which the fabric is moved from one stationary part to another stationary part of the container;
- a stationary tangential substantially vertical fabric delivery on respective sides of said winch;
- means subjecting the fabric to the action of a treatment medium during its movement inside the container including a stationary nozzle substantially vertically below each respective delivery above each of said respective parts of said container for treating said fabric with fluid;
- means for maintaining the two ends of the fabric in respective parts of the container such that the winch can be alternately driven in opposite directions;
- said winch lifting the fabric substantially vertically from one part of the container, and laying it down substantially vertically in the other part of the container, and vice-versa,
- whereby the fabric is treated along the route of the fabric between said parts of the container means.
The method of dyeing a length of fabric comprising the steps of:
- depositing said length of fabric in a stationary container;
- providing driven transport means having a stationary tangential substantially vertical fabric delivery on respective sides thereof in combination with a stationary nozzle substantially vertically below each respective delivery;
- lifting the fabric substantially vertically in running length from one stationary part of the container by said transport means;
- continuing to move the fabric in running length substantially vertically downwardly from a stationary tangential delivery in a substantially tensionless state while applying a dyeing liquid from a stationary nozzle to said fabric and depositing same in another part of the container;
- then reversing the direction of movement of the fabric again lifting the fabric upwardly in running length from said another part of the container;
- and
- then again applying a dyeing liquid to said fabric while continuing to move said fabric in running length, prior to depositing same vertically in said one part of the container;
- whereby a dyeing liquid may be applied evenly and without immersion during application thereof.
Apparatus for dyeing a length of fabric comprising:
- a liquid container;
- a partition dividing said container into at least a pair of stationary vertical compartments;
- a power operated transport means having a stationary axis and a stationary tangential substantially vertical fabric delivery on respective sides thereof alternately moving said fabric from one of said compartments into the other of said compartments;
- a nozzle carried substantially vertically below each of said deliveries fixed with respect to said compartments each receiving said fabric and delivering same into one or the other of said compartments;
- pump means collecting liquid from respective compartments so that substantially no liquid remains therein to impede the fall of the fabric and returning collected liquid to at least one of said nozzles;
- whereby said fabric may be dyed while being conveyed rapidly from one compartment to the other without substantial tension.
