Finishing with powdery substances
Altering the characteristics and properties of hygiene papers
Special hydrophilic behaviour is desired with hygiene papers such as kitchen towels, napkins or toilet paper to make them absorbent. At the same time, these papers must not lose any of their strength to prevent them from becoming too soft and tear. In addition, they shall feature skin care properties or fragrances. The task is to furnish tissue with the desired characteristics or individual properties through a precision-metered application of a substance.
Application of powdery substances
The application of powdery materials, such as encapsulated substances, makes tissues, for example, especially absorbent without losing strength. Fragrances and skin care substances can also be applied.
Exactly metered application of powdery substances
WEKO-Powder-Application-System (WPA) such as WEKO-AP provide many choices with the production of tissues. Even at top speeds and the associated dynamic processes, PAS work with high precision and reliability because of their highly efficient application nozzles. This reduces the required application quantity as well as soiling of the plants and provides maximum quality.
Tissues need WEKO-AP
The powder systems WEKO-AP and WEKO-ESC are custom-tailored for the high demands of advanced machines for the production of tissues. They have been designed specifically for the preparation of a powder-air mixture and an accurately reproducible and extremely uniform powder application. Several compact systems with widths up to four metres are available for you to choose from. In addition, the WEKO-AP200 and WEKO-AP300 offer the VARIOBOX® System for quick powder change.
