Effect of Electrolytes on the Rate of ‘Supercontraction’ of Wool Fibres


WOOL fibres have been shown to shorten (super-contract) when held in steam and rapidly stretched and relaxed, or when treated with hot solutions of reagents breaking disulphide bonds, with cold solutions of metal ammonium hydroxides, or with hot solutions of formamide, certain phenols, or lithium bromide (see Alexander and Hudson1).
