Abstract:
Odor-absorbing sheet-like structure comprising vegetable and/or manmade fibers, in particular a sheet-like structure having an air permeability suitable for filters and vacuum cleaner bags, which sheet-like structure has zinc ricinoleate in an amount in the range of 0.1 to 20% by weight, based on the weight of the sheet-like structure, in finely divided solid form on at least a part of the free fiber surface, and method for its production by treatment of a sheet-like structure with a dispersion of fine zinc ricinoleate particles or by spraying on a mist of a melt or solution of zinc ricinoleate.
