Abstract:
Apparatus for performing optical readings on yarn spools subjected to dyeing in a dyeing tank or machine (1) in which a spool (6) provided with a pierced axial shaft (6A) is placed with the said shaft on the outlet of a feedpipe (IM) of a circuit that feeds a dyeing bath in the same tank or machine (1), so that the dyeing bath enters the dyeing tank or machine (1) passing by the feedpipe (IM) through the shaft (6A) and is subsequently collected through collecting conduit (IR) of the same feeding circuit. The apparatus comprises optical detection means connected with electronic processing means and the said optical detection means comprise a detector (9) with an optical window (92) located inside the dyeing tank or machine (1), a base of the spool (6) being cyclically put in contact with said optical window (92), periodically, the said spool being moved towards the optical window (92) by means of an actuator (7) which, cyclically, moves the said shaft (6A) the said base of the spool (6) towards a part (2) of the dyeing tank or machine (1) where the said optical window (92) is located.
Abstract:
A multi-container dyeing machine includes a machine frame base, a heating and cooling module having multiple temperature-controlled heating and cooling devices each consisting of a housing, a container, a heating unit, a temperature sensor, a transmission wheel and an electric fan and a mounting plate mounted in the machine frame base to carry the temperature-controlled heating and cooling devices, an automatic quantitative feeder for selectively feeding an auxiliary agent to the containers of the temperature-controlled heating and cooling devices selectively without interrupting the machine and a swinging mechanism controllable to tilt the mounting plate of heating and cooling module and the temperature-controlled heating and cooling devices.
Abstract:
A dyeing machine includes a beaker and a carrier within the beaker. The carrier includes a perforation and supports a sample. A pump assembly circulates a processing solution to a first side of the carrier. The processing solution passes through the perforation for dyeing the sample from the inside-out. The carrier is substantially a cylinder.
Abstract:
An apparatus for dyeing textile materials is provided that includes one or more chambers for dyeing and one or more storage baskets. The apparatus has a first station with a container hydraulically connected with the chamber. The first station is for the drawing and metering of dyeing solutions and for the admission of the dyeing solutions into the container to feed the chamber for dyeing the material disposed inside the storage basket. A second station has a stirrer. The basket is connected in a stable but removable way to the stirrer. The basket is located in correspondence with the chamber.
Abstract:
Each beaker is pivoted in such a manner that its longitudinal axis is tilted. Each beaker is equipped with a dosing hose, via which additives can be fed into the inner space of the beaker. Accordingly, the additives can be fed in a controlled manner and continuously or step-by-step into the beakers which are continuously moving, i.e. without any interruption of the movement of the beakers. This leads to a more uniform laboratory dyeing within the surface of the specimens.
Abstract:
Apparatus in accordance with the invention is of the type in which textile fabric samples are dyed in a generally cylindrical vessel containing a liquid dyeing bath while being moved in a cyclical fashion by a sample holder having a generally vertical rod connected to an overhead stirrer. The improved apparatus includes means connected to the generally vertical rod for holding the textile fabric sample in a generally cylindrical configuration, a pump for pumping a concentrated chemical solution at a controlled rate, and means for supplying the concentrated chemical solution from the pump under the surface of the dyeing bath in at least two vertically spaced-apart locations.
Abstract:
Equipment for wet processing a textile sample is described in which the sample is located in a container and the treatment liquid is made to flow past the sample by a magnetic agitator rotatably driven from outside the container by a magnetic field producing mechanism.
Abstract:
TEST DYEING APPARATUS COMPRISING A FRAME, AT LEAST TWO DRIVING ROLLS ROTATABLY SUPPORTED ON SAID FRAME IN A HORIZONTAL PLANE IN PARALLEL RELATIONSHIP AT SUITABLE DISTANCES, MEANS FOR DRIVING SAID DRIBING ROLLS, HOLLOW DRUMS EACH ADAPTED TO BE PUT ON A PAIR OF SAID ADJACENT DRIVING ROLLS AND HELD IN TANGENTIAL CONTACT THEREWITH SO AS TO BE DRIVEN THEREBY AND TUBULAR DYEING TANKS FOR CONTAINING DYEING SOLUTION AMD MATERIAL TO BE DYED, EACH OF SAID TUBULAR DYEING TANKS BEING ADJUSTABLY SUPPORTED IN SAID HOLLOW DRUM SO THAT THE FORMER MAY BE SET AT A DESIRED ANGLE RELATIVELY TO THE LATTER.
