The BLO-WASH range is the culmination of a development programme carried out to avoid these faults in which the prevention of running lines has been resolved by eliminating nip rollers.
- Rope scouring / softening of a huge range of fabrics
- No fears of running marks
- Low maintenance costs
- Easy to operate
- Easy to clean
- Low power consumption
- Low water consumption and Liquor / Goods ratio
- Manual or Automatic operation
- Unique circulation system ensuring even application of chemicals
- Constant pH monitoring
The Blo-wash machine works on the principle of a double venturi system contained in a precisley engineered channel head. The first venturi passes circulating scouring liquor or fresh rinsing water via a self-priming centrifugal pump, and the second circulated air. Both venturis have filtration systems in line to avoid blockages with lint etc. Fabric in rope form is presented to the system using a single fabric lift roller having minimal fabric contact, thus avoiding the formulation of creases in the fabric rope – there are no nip rollers in the machine.
Following the venturi system is a specially designed blow tube in which the fabric is carried on a cushion of air or air/liquor mixture. On exiting the blow tube, the air – air/liquor mixture dissipates over a large area thus opening the fabric rope, further avoiding the formulation of creases.
The fabric running speed, controlled by the fabric lift roller, is variable and determined by the total weight of the fabric and liquor passing through the blow tube. Typically scouring speeds of 350 m/min are achievable whilst dry tumbling speeds of 700 m/min are common. At these speeds the fabric is thrown against a perforated plate installed in the rear door of the machine achieving a softening / milling effect. Within the perforated rear door is a catchment tray through which liquor passes for re-circulation via the centrifugal pump.
pH monitoring is installed and chemical additions are made through a tank installed between between the catchment tray and the circulation pump. This system enables even application of chemicals such as chemical softeners and fireproofing agants for wool / woolen fabrics. Heating of the liquor using a steam coil installed in the sub-base of the main tank enables processing temperatures up to 80°C to be reached.

FABRICS SUCCESSFULLY PROCESSED IN BLO-WASH MACHINES
- Featherweight fabrics used in 100% wool/worsted, cashmere or linen
- Polyester / viscose and polyester / wool blends for scouring and softening
- Poylester / wool blends with Lycra, at 80°C, to promote initial development of stretch
- 100% nylon workwear fabrics
- Woolen coatings, jacketings and fabrics for travel rugs and blankets
- 100% cotton fashion fabrics
- Silk and blends of silk with viscose, wool and other fibres
- Acrylic fabrics with chenille weft
- Dry tumbling to achieve “stone-washed effects”
The Blo-Wash is controlled by means of a touch screen. From the main screen, the various control screens can be activated.
All operations may be controlled manually, including the lift roller speed which is infinitely variable up to 700m/min. A manual process timer is included. The system status and any faults present are displayed.
The selected cycle program is activated from the automatic screen, and its progress monitored. The cycle may be halted at any time to enable process inspection. Again, the system status and any faults present are displayed.
Many different programs may be prepared and stored within the control system, which can be developed for different fabrics and required effects. Variables which may be controlled include step times, fabric speed, and liquor temperatures throughout the various stages of a program
