Cleaning cloth contg. detergent - fixed to web or foam with organic binder and covered with porous top

摘要

Cloth contains one or more deposit layers (1), in which detergent is fixed with water-insoluble organic binders, e.g. wax or thermoplastics. At least the flat sides of the deposit layers are covered with porous top layers. Cloths can be used for household cleaning, for cleaning wind-screens, offices etc. Cloth can be used repeatedly without exhausting deposit. In an example, viscose web was (1) treated with 22 g/m2 of paste contg. 40 g alkylbenzene sulphonate in 20 g wax + 150 g C2HCl3, (2) lined with fleece. Detergent activity (measured as foam level in mm) fell from 37 mm to 15 mm after 5 cycles and to 2 mm after. 10.
