WEKO 
The company for contact-free and precise surface application of specific functional properties, Weko, Weitmann & Konrad GmbH & Co. KG, Leinfelden-Echterdingen/Germany, is specialized in applying finest surface coatings in liquid or powder form contact-free, precisely and easily repeatable on (technical) textiles or nonwovens in a variety of process steps.
From water-based and oil-based liquids to alkalis and acids, the systems are adapted on the material side to the individual requirements, e.g. in order to achieve specific special properties, such as hydrophilic, hydrophobic, dirt, grease and oil repellent, flame retardant, antimicrobial, alcohol repellent, anti-fog, antistatic, grip changing (or other diverse functions.
The contact-free Weko-Fluid-Application-System (WFA) applies liquids by fast rotating rotor discs which spray ultra-fine micro-droplets to the material web. To prevent the undesirably escaping of aerosols and to achieve a working environment, the encapsulated Weko-ProTec offers very clean precision. With non-contact spray application the material is handled with great care since no mechanical stress is applied on the fabrics by squeezing between rollers.
WFA only applies the amount of chemicals which are really needed. The drastic reduction of chemical auxiliaries is important for a sustainable and cost efficient production. Up to 70% can be saved with the WFA system due to possible single-sided and purely surface application if necessary.
With the classic padding procedure, roughly 70% of moisture is retained by the fabric even after squeezing. By comparison, the non-contact application system from WEKO has a reduced pick-up of approx. 15–25%.
Consequently, the finishing requires significantly less drying energy and energy savings up to 60% are feasible. Alternatively the reduced energy required during drying allows obvious increasing machine speeds up to 100%.
Textiles, specially knitted fabrics, need to be cut at the selvedge to obtain a strait and regular side for a parallel roll and perfect doubling. Depending on the required processes, some fabrics need to be cut several times (2 or 3 times).
To reduce this waste and on the other hand increase the material output, WEKO has developed his cutting system Cut-it 2.0. With special fabric guiding, de-curling and stabilization solutions, the cut selvedge can be reduce up to 80% compared to common cutting systems.
