Non-contact spray application of liquids for functionalising

The WEKO-Fluid-Application-System (WFA) scores high with precision and economy. WEKO provides application precision, potential savings of energy and chemistry as well as gentle handling of nonwovens and textiles. The system meters the liquid application exactly and reproducibly. The finishing liquids can be applied entirely as needed and according to the intended purposes in smallest amounts. Thanks to the minimum application, drying can be excluded in many cases. Solutions remain free from contamination through the non-contact application and can be reused. Depending on the application scenario, annual savings up to 6-digit amounts are possible. WEKO application systems represent both highest industrial requirements and also cost and ecology-minded production.

WEKO-Fluid-Application-System (WFA) for the finishing of nonwovens are comprised of the Liquid Supply Unit and System Controller WEKO-FLOW and the Rotor Carrier WEKO-SIGMA. Compact and adaptable to a variety of system configurations, they allow for the rapid change to the respective necessary product formats, product speeds, scope of application, etc. Based on the WEKO rotor technology, proven in practice, we have developed an encapsulated rotor carrier which safely and reliably prevents contamination of the surroundings. With the WEKO-ProTec we have succeeded in combining the numerous benefits of non-contact liquid application of WEKO with the requirements on an extremely clean production environment - expanding the application options of WFA for our customers.

WEKO offers non-contact precision application systems for a wide variety of fluids enabling the functional finishing of your textile fabrics and nonwovens. Convincing factors are the economy and exactly reproducible application quantity that guarantee high process reliability. In addition, WEKO-ProTec, the encapsulated application unit, allows you to safely handle substances that should not be perceivable in the working environment. This may include aerosols exhibiting unpleasant odours or also slippery silicons or oils. With the encapsulation and highly efficient extraction, WEKO provides a solution that reduces the health risk at the workplace while preventing unpleasant odours at the same time.

Principle of WEKO-ProTec encapsulation: The significant improvement of protection against undesirably escaping aerosols and the cleanliness of the environment is achieved through the very easy to operated encapsulated application unit. By opening, the material is easily and quickly introduced. After closing, the highly efficient extraction provides the desired protection. Benefits of WEKO-ProTec:

• PROTECTION OF THE WORKERS’ HEALTH  because the escape of harmful aerosols is prevented
• SAFETY AT THE WORKPLACE  by preventing environmental contamination through slippery substances
