Abstract

Highly adsorbent and water-absorbent artificial fibres are obtained by incorporating in a spinning solution finely divided activated charcoal which has been impregnated with an alkali-stable emulsifying agent, and then extruding the solution and forming fibres therefrom. The activated charcoal may be incorporated in viscose, cellulose acetate solutions or other cellulosic solutions. The alkali-stable emulsifying agent may be a poly-galacturonic acid, a saponin or a polyhydric alcohol. The proportion of activated charcoal incorporated in the spinning solution may be up to 10 per cent. by weight based on the filament-forming substance. The fibres so obtained may be used for making bandage materials. The Specification as open to inspection under Sect. 91 comprises also the production of artificial fibres from spinning solutions which contain silica gel or which contain water-glass. In the latter case a coagulating bath containing sulphuric acid is employed, whereby silica gel is deposited in the fibre during its production. The use of an emulsifier is not essential. This subject-matter does not appear in the Specification as accepted.
