    Abstract: Wool and wool-containing textiles are shrink-proofed and felt-proofed by treating them with dichlorcyanuric acid and/or trichlorcyanuric acid in an alkaline aqueous solution or suspension. The treatment bath preferably contains 5.5%-14% by weight of dichlorcyanuric acid or 4.5%-11% by weight of trichlorcyanuric acid or mixtures thereof in an amount corresponding to 2%-5% of active chlorine with reference to the weight of the treated material, and the pH of the bath is preferably adjusted to above 7 by the addition of buffer substances, e.g. borax and alkali-metal phosphates. The bath may also contain other oxidising agents, e.g. salts of monopersulphuric, dipersulphuric, peracetic and perbenzoic acids, inorganic salts, e.g. sodium chloride, sodium bromide, sodium sulphate, calcium chloride, magnesium sulphate and zinc sulphate and/or organic salts, e.g. the alkali and alkaline-earth metal salts of acetic acid and ethylenediamino tetracetic acid, and wetting agents. The treatment may be carried out at room or elevated temperature, e.g. 20 DEG C.-40 DEG C., for about an hour and the material may then be rinsed with cold water and treated with a reductive or oxidative dechlorination bath, e.g. an alkaline metal bisulphite or dithionite, a salt of a hydroxyalkane sulphinic acid or a reaction product of such an acid with ammonia or hydrogen peroxide.

    Abstract: Dyeings with reactive dyes on cellulose fiber materials are after-treated with an aqueous solution of a condensate which is obtainable by reacting (a) bisbenzylpiperzine with (b) ethylene chloride, an epihalohydrin, propylene chloride, 1,3-dichloro-2-hydroxypropane, bisepoxybutane or 1,4-dichlorobutane or a mixture of these, in a molar ratio of from 1:0.5 to 1:1.1, or by reacting (c) piperazine, bis-1,4-aminopropylpiperazine, 1-aminoethylpiperazine, 2-hydroxyethylpiperazine or 1-methylpiperazine, or a mixture of these, with a compound according to (b) in a molar ratio of from 1:0.5 to 1:1.1 and benzylating the condensate, the benzylation being carried out using 0.15-1.0 mole of benzyl chloride per equivalent of nitrogen in component (c). The cellulose fiber materials after-treated in this manner possess very good wetfastness.
