    摘要: This invention provides a combined dyeing and polymer deposition process for protein fibres. The fibres are treated in a liquid containing a dye, a polymerisable olefinic monomer and a catalyst in the form of a complex of copper, iron, chromium, manganese, vanadium, cobalt, nickel and aluminium together with a trihaloacetic acid or a salt or ester thereof. Other substances which can form trihalomethyl ions or free radicals in the presence of the complex can also be used. The combined catalyst of metal complex and trihaloacetic acid enables polymerisation of the monomer to be carried out in the presence of air and also permits formation of the polymer within the fibre substance rather than at the surface or in the liquid. The dye may be an acid, premetallised or reactive dye and is usually applied simultaneously with the polymer, for example by heating the fibres in an aqueous solution containing the reacting materials gradually from room temperature up to a temperature in the range 50* to 100*C and maintaining them at that temperature for between 30 minutes and 2 hours. The invention enables wool to be coloured and to have its physical and mechanical properties altered by polymer deposition in a single operation in a single bath, as well as ensuring that as much as possible of the polymer forms within the substance of the fibres.

    摘要: The invention includes a method and apparatus for use in wool scouring operations and the treatment of the aqueous scouring liquids after and during use to extract recoverable lanolin or wool grease and heat from such liquids, and separate solid and extraneous matter from the liquids prior to discharge. The method and apparatus provides for removal of excess liquid from wool leaving a main scouring tank, passage of hot liquor and suspended solids from the wool and main scouring tank to a side tank, recycling of liquid from which solids have precipitated and passage of the solids to a heavy solids settling tank via a dump tank, removal of heavy solids precipitated in the settling tank and passage of the remaining liquid through a lanolin extractor; and recycling the remaining liquid or discharging all or part of such remaining liquid to waste via a heat exchanger which recovers heat from the discharge liquid for heating fresh water or liquid.
