Santex is primarily involved with the finishing of knit fabrics.
However, every stage from spinning, knitting to dyeing, affects the behaviour of the fabric and determines the fabrics characteristics and how the finishing machines need setting in order to achieve the best results.
Reference to best results not only refers to fabric quality but also optimization of machine usage and minimising of costs especially energy costs. Following on from the successful Santex Enairsave heat recovery system, Santex have further developed the area of energy saving with the new ESC (energy saving chamber). From the outside the Santex ESC chamber looks just like a standard Santashrink heating chamber, but internally the air is handled in a completely new way. The Santex ESC is a chamber which can be added in front of an existing Santashrink Standard dryer.
What is the difference between Santex Enairsave and Santex ESC?
Whereas Enairsave is mainly used on Santashrink Jumbo or Super Jumbo dryer and is focused solely on saving energy, Santex ESC is also designed to increase productivity.
Up to 20% Energy saving
Standard energy saving devices use hot exhaust air to preheat the incoming fresh air through external heat exchangers. Santex ESC however uses the hot exhaust air to directly preheat the incoming wet fabric. Efficient use of energy is ensured through cycling of air in the ESC chamber. The effectiveness of the ESC can be identified through reduced exhaust air temperatures at the exit. With a Santex ESC chamber at the inlet of a dryer, and depending on exhaust air temperatures, an increase in productivity of between 15% to 20%, and a similar range in energy saving, can be achieved. The ESC can be supplied either with standard Santashrink manual filters, or integrated within the automatic lint cleaning system of the existing dryer. The nozzles in the ESC have been specially developed to further increase dryer productivity.
Automatic filter belt
On request the retrofit Santex ESC chamber can be supplied with an automatic lint belt cleaning system to work independently of an existing dryer with manual filters. Similarly the choice of machinery shouldn’t only look at installed power heat exchanger capacity, but ultimately at what is the productivity and what the energy costs per kilo fabric are. In the end the cost of machinery is a lesser part of the overall cost of purchasing a machine particularly when future costs of power and fuel are likely to rise. In addition, features such as the high lofting action of Santashrink may also lead to less softener being necessary to achieve the required fabric feel. With increased pricing pressure from buyers, ever increasing utilities costs and environmental constraints from governments or from retailers the more efficient use of current equipment and the adoption of new technologies will enable textile manufacturers meet the new challenges of the market.
