Abstract

Cellulose fibres having a low water retention capacity and a low water holding capacity as well as a high immersion time, and that are processable into a non-woven exhibiting as short a droplet penetration time as possible, as low a wet retention as possible and as slight a wetback as possible, contain, (a) as mineral fillers, barium sulphate, talcum, muskovite, or a mixture thereof, in an amount of from 15 to 60% of the total fibre mass, and, if desired, (b) additionally, hydrophobic, polymer or oligomer substances, such as polyethylene, polypropylene, polystyrene, polyacrylic acid ester, polyester, polytetrafluorethylene or waxes, in an amount of from 1 to 60% of the total fibre mass. The fibres are produced in a process in which the mineral fillers and, if desired, the hydrophobic, polymer or oligomer substances - preferably as an aqueous suspension of the same - are admixed to a viscose, and the mixture is wet- spun.
