Physico-Mechanical Properties And Application Of Man-Made Fibres


-- It has been found that the primary swelling of fibres prepared from solutions of cellulose curpimonium complex has an extremal dependency on the composition of the aqueous—organic precipitation bath.

-- The character of the dependence of the swelling of the finished CuC and HC fibres on composition of the mixed precipitant indicates a structural memory of the fibre during the transition CuAC → CuC → HC.

-- The extremal character of the temperature dependence of swelling of HC fibres in a solvent + precipitant mixture is probably brought about by several oppositely directed processes, including complex formation, change in solubility, ionization, etc.
