The Superiority of EVAC System Modules
Evac provides you with process capability and reproducibility at low running cost due to the following System Modules: Patented EVAC Slot, EVAC Separators, EVAC Pumping Station, and EVAC System Controls.
Process Capability and Reproducibility at the Lowest Cost
No other vacuum system available today contains all of these design features, which make Evac systems the superior choice in overall performance.
Vacuum Technology - The Principle
Evac systems integrated into open-width textile ranges will improve fabric quality, increase production speed, signiﬁ cantly lower production cost per meter, and lessen the overall environmental impact of textile processes. Following are just a few examples of how vacuum technology can achieve these advantages for the textile producer.
Improved Fabric Quality
Vacuum technology improves fabric quality by removing lint and dust when dry, and by improving chemical penetration in wet processes. Lint or dust removal can be very advantageous in printing where “stickins” result in second quality fabric. In chemical ﬁnishing and pigment “dyeing”, vacuum can pull the chemicals deep inside the fabric, where the end-user appreciates them most. Vacuum technology also prevents the “windowpane” effect, or chemical build-up between yarns.
Increased Production Speed
By lowering residual moisture below the level of typical padmangles, vacuum technology allows stenters and other drying devices to dry fabric faster, thus increasing production speed, or lessen the energy consumption.
Lower Production Costs
In washing, vacuum technology separates contaminants from the washing line before they are carried into following washing boxes. The effect: less clean water is needed, which also results in less energy consumption for hot washing purposes. In ﬁnishing, vacuum technology removes the chemicals suspended between fabric yarns. The chemicals stay inside the ﬁber bundles of the yarn, not in between the yarns, and can, easily be recycled. Therefore, fewer grams of chemicals per square meter of fabric are required when using vacuum technology in ﬁnishing than when using the padder alone.
Reduced Environmental Impact
In washing, parts of the counterﬂowing dirty liquor is sent to separate treatment by using the vacuum system. PVA size, bleaching chemicals or unﬁxed dyestuffs are removed from the washing line before they enter the succeeding wash boxes. Likewise in ﬁnishing, by removing chemicals such a ﬂuorocarbons, resins, softeners and even pigments normally left in between fabric yarns, very little chemicals remain to become vaporized and exhausted as emissions out of the stenter’s exhaust outlets.
Easy to Handle – Safe Operation
The operator only selects the vacuum pressure needed and the Evac automatically adjusts pump speeds and airﬂows to ensure consistent pressure and production results. Pumps as well as seals and separators need only minimal, routine
More than 30 Years of Experience
It is not just the quality of our vacuum systems that makes us number one world-wide. It is also the process experience behind the Evac system designs that ensures that the customer receives a vacuum system that is tailored to his speciﬁc needs, for as yarn characteristics and fabric constructions vary tremendously, so too do the potential
effects of vacuum pressure vary from fabric to fabric. Take advantage of Evacs knowledge in vacuum technology!
