Current dust cloths are mostly made of nonwoven polyester or polypropylene. The synthetic fibers become electrostatic through friction, so that the cloth attracts fine dust and hairs. But these materials are weakly particle-attracting due to the weight of particles. Current disposable dust cloths have a low wettability of water-based liquids. Improvements can be made by adding fibers or other components which increase wettability and absorbance. But this weakens the cloth and the electrostatic properties.
Target: We are seeking for proposals for a disposable material that is mainly used for dry dusting and is able to entrap fine dust as well as larger particles. In addition the material can be treated with water-based liquids for “wet” applications.
The successful technology will provide a disposable cloth for wiping surfaces that will meet the following criteria:
Approaches should not include adhesives, oily impregnation or superabsorbants.
