Bio polishing is a commonly used treatment for cleaning knit fabrics to improve their quality. However, there are many challenges inherent in this process:
- Fluff management on the shop floor
- Considerable reduction in the depth of the shade after bio-polishing
- No consistency in results, as it is a batch-wise treatment
- High weight loss
- High tensile strength loss
- Expensive chemistry
- High increase in the COD volume and process effluent due to the water and auxiliaries used for bio-polishing
- Bio polishing is an additional process which increases the effluent volume
Bio polishing hence has high costs associated with it. Moreover, with ecological concern and sustainability assuming global importance, it is even more important imperative for the industry to change its processes to address these concerns. Continuous open-width singeing is an excellent, economical, and sustainable alternative that can effectively overcome the challenges posed by bio polishing.
A.T.E., the complete solution provider in textile machinery, represents Osthoff-Senge GmbH, Germany, and the market leader in open width singeing technology.
Osthoff-Senge has specially developed a new singeing machine for processing open-width knit goods with a working width of up to 2600 mm.
Open-width knit singeing offers many significant advantages, such as;
- Improved surface quality
- Reduced loss of weight and tensile strength
- Lower production costs
- No increase in effluent loads
- Clean shopfloor
- Consistency in results
Features
The system features well-proven double jet burners and proportional gas-to-air mixing with pre-selected singeing positions. It includes a selvedge uncurling mechanism, driven spreading scroll roll assembly, and centering devices. A short distance between the guiding rollers prevents the selvedge from rolling off. The fabric is protected by a water-cooled roller when the flame is active. The machine is designed to singe on one or both sides of the fabric in a single passage. After singeing, the material is guided to a suction cleaning unit. A fabric pull roller is installed on top of the singeing machine to pull the fabric without stretching it. To avoid fire hazards, the knit fabric is guided via a scroll roller into a steam box. Finally, the fabric is delivered via a plaiter into box carriages.
Around 150 Osthoff open-width knit singeing machines are now working satisfactorily across the world. Three machines are already working in India: Tee Jay (Vishakhapatnam), Bhoomi Textiles (Ahmedabad), and Victus Dyeing (Tirupur). The machine supplied to Arvind (Ahmedabad) is under execution.
Many delighted customers have acknowledged that the operational cost of the Osthoff knit singeing machine is nearly 50 per cent lower than the bio polishing process.
