HiTech cleaning wipers (also known as cleanroom wipers) consist of decontaminated multifilament knitted yarns made of polyester or polyamide. The knitted roll material is cut into handy wiper formats with laser cutters and then, depending on the purity requirements of the user, decontaminated in one or more stages.

In our glove portfolio, we manufacture non-slip flat-lay gloves made of polyurethane nonwoven that are highly comfortable to wear. The gloves are breathable so that perspiration from the hand can evaporate.

Stretchbond ™ gloves are worn where the high level of comfort justifies the additional price and no liquid barrier is required.

The production of our standard cleanroom wipers from nonwovens, on the other hand, is almost fully automated. Our Interfalz wipers are suitable for dispensers. The "interfold" type of folding allows only a single wipe to be taken from the dispenser each time a wiper is needed.

In our special paper production, electronically controlled cutting machines with stacking lifts are used. The development of cutting dust on the edges of the paper is monitored microscopically and eliminated if necessary. Notebooks and logbooks for use in clean working areas are also produced here, as are disc separators for ultra-pure flat products.


Monitoring our delivery quality is the core task of our quality assurance. For us, this includes the following measures:

  • The involvement and motivation of all employees in the constant improvement of manufacturing quality.

For the highest possible transparency of our product quality, we publish the test data of our best-selling high-tech cleaning cloth on the Internet every week:

Our HiTech cleaning wipers are available in various decontamination levels. In addition, depending on the intended use, they can be carried out in the decontamination types aquatic, organic and supercritical.

Since 1985 we have published 40 technical articles and 10 patents on the subject of surface cleanliness and wiping cleaning procedures.
