Sorptive properties of fibres prepared from cuprimonium solutions of cellulose

-- The sorption of water vapor by copper-containing and by final hydrocellulose fibres from the cuprimonium preparation method essentially does not depend on the concentration of the water-diethylene glycol precipitation bath or on stretching in the range up to 34%, which indicates formation of structures which are close to amorphous fibre in packing density under these conditions.
