The right web cleaning method for your production process depends on a variety of factors, including:
- sensitivity of the surfaces to be cleaned.
- level and type of contamination.
- web speed.
- web tension.
Every kind of moving surface has its specific properties.
Fibrous webs such as tissue or non-woven, for instance, can’t be cleaned via contact cleaning. The mechanical forces of the cleaning not only gets rid of the contamination from the web, but also damages the structure and surface of the web.
Film and foil can be cleaned perfectly by means of sticky polymer rollers. This is because the surface of the web has a good mechanical resistance against the cleaning power and the level of contamination is usually moderate.
Textiles need a non-contact method, because increasing web tension leads to a variation in web width. These are just a few examples of the aspects that are involved when choosing the right web cleaning method.
