The COLORCOMBI is the ideal machine for dyeing polyamide, nylon, cotton, wool and their blends, also ready-to-wear garments.
By means of a high-capacity pump, the dyeing bath circulates parallel to the outer drum of the machine. This circulation results in a gentle recirculation of the dyeing bath in addition to the drum rotation. This process allows extremly gentle dyeing processes with low drum speeds.
In connecton with a multi-function dosing system, the liquor ratio remains unchanged when dosing chemicals and dyestuffs, as for the dosing process liquor from the machine can be used (istead of fresh water). Thus, rinse water accruing from the dosing process do not change the liquor ratio.
As a standard, all drum dyeing machines of the type COLORCOMBI can reach a maximum dyeing temperature of 104 °C (220 °F) at a pressure of 0,3 bar (4,35 psi). The outer drum is designed as a
low-pressure vessel in accordance with the valid precriptions of the German Technical Supervisory Board (TÜV).
The exterior drum is connected to the stable base frame of the machine by vibration absorbers so that a machine operation poor in vibrations is guaranteed. If the admissible unbalance is exceeded, the machine switches off automatically.
The inner drum is available in following types of construction:
1. as Y drum, i. e. with three compartments
2. as open drum
The inner drum is provided with a special perforation and is mirror-finished in a special process.
The heat exchanger for the indirect heating and cooling is located in the outer drum and ensures heating and cooling speeds of 5° C per minute at respective steam and water conditions.
It is also possible to cool down the machine directly from a liquor temperature of ≤ 98 °C. For this, optionally the machine overflow in order to rinse oils as well as the liquor drain valve can be used. Flottenablassventil benutzt werden.
The sampling device is located in the upper third of the drum cross-section.Die Mustervorrichtung ist im oberen Drittel des Trommelquerschnittes angeordnet.
The machine is equipped with a dosing system with four dosing tanks (standard) where all dyeing stuffs and auxiliaries can be prepared prior to operation start. These tanks are installed at the frame of the dyeing machine optionally at the left- or on the right-hand side.
The dosing system includes the water connections for:
1. soft water cold
2. soft water warm
3. hard water cold
For cleaning the tanks, a seperate rinsing line is provided as well. The dosing is effected automatically by means of th machine control.
The drum of the machine is driven by a three-phase servo motor which covers the whole tange of the dyeing as well as the hydro extracting speeds.
All machine parts coming in contact with the dyeing liqour such as drum, heating device, valves, etc. are made of stainless steel, materrial no. 1.4571 or 1.4404 resp.
As a standard all switch cabinets are made of stainless steel and equipped with a cooling device.
The standard control unit of all drum dyeing machines is the Sedomat. The entry of programs into the control device is realized in dialogue in plain text via an LCD display. In automatic operation, the dyeing process is displayed as a graphic diagram and executed accordingly. The nominal and the real values are shown graphically and render possible a quick optical control of the dyeing process.
