Abstract

Keratinic textile fibres, e.g. wool, are given improved resistance to setting and may be bleached, by treating them with a solution containing an alkali metal salt of N-dichloroisocyanuric acid and an alkali metal permanganate and having a pH of 6.5-9. The pH of the solution may be adjusted by the addition of alkali. The concentration of N-dichloroisocyanuric acid salt in the solution is preferably such that the active chlorine content of the solution is 1-5% by weight of the fibres being treated and the concentration of alkali metal permanganate, e.g. potassium permanganate, may be 0.5-2.5% by weight of the fibres being treated. The weight ratio of textile materials treated to processing bath is preferably in the range 1:5 to 1:60 and the treatment may be carried out for 20-90 minutes at 5-35 DEG C. The treating solution may also contain an anionic, cationic or non-ionic surface active agent, e.g. a condensate of ethylene oxide with lauryl alcohol. The fibres may subsequently be dechlorinated by treatment with an aqueous solution containing sodium bisulphite or hydrosulphite. The fibres may be in the form of wadding, combed or carded ribbon, thread, woven or knitted fabric or made-up articles.
