    摘要: Textile fibers, particularly cotton, are treated with polymeric cationic pretreatment agents to improve the colour yield and wet fastness properties of subsequent dyeing or printing. The polymeric pretreatment agent may be
    (A) the reaction product of a monofunctional or polyfunctional amine with dyanamide, dicyandiamide, guanidine or bisguanidine or (B) the reaction product of (A) with
    (a) an N-methylol compound (b) an epihalohydrin (c) formaldehyde or (d) an organic compound containing at least two groups capable of being split off as anions on reaction with (A) or mixtures of these or (C) a mixture of
    i) the reaction product of (A) with (b) or with (c) and ii) an N-methylol compound (a), or mixtures of (A) with (B) and/or (C). The pretreatment process is such that at least 0.6% wt. of the pretreatment agent remains fixed on the fibres. The reaction products of (A) with (d) are novel.
