    摘要： A polyamide resulting from the reaction in any order of

    a) a bifunctional agent of the formula:
    wherein x is zero or a whole number up to 7,
    Z is selected from
    each of R₁ and R₂ is selected from lower alkyl and lower hydroxyalkyl radicals,
    Y is selected from alkylene radicals with from 2 to 6 carbon atoms, 2-hydroxy-1,3-propylene radicals, and the radicals
    with the proviso that when x is greater than 2(and therefore more than 2 symbols y are present) each of the symbols y need not necessarily have the same significance; with
    b) the reaction product of i) a dicarboxylic acid of the formula:
    HOOC-C m H 2m -COOH
    in which m is an integer of from 4 to 8, or a functional derivative of said dicarboxylic acid, and ii) a polyalkylene polyamine containing two primary amino radicals, at least one secondary amino radical and at least two alkylene radicals, the molecular proportion of i) and ii) being 0.85:1 to 1.2:1, and
    c) epichlorohydrin.

    A method for the treatment of wool so as to impart shrink resistance is also provided. The method comprises the steps of:-

    i) subjecting the wool to an oxidative chlorinating pretreatment, and
    ii) subsequently treating the wool with an aqueous solution of a polymer so as to cause the polymer to be applied to the wool fibres. The polymer used in step ii) is a polyamide of the aforementioned type.

    摘要： A continuous process for the production of shrink-resistant wool comprises:

    i) subjecting the wool to an oxidative chlorinating pretreatment;
    ii) subsequently treating the wool with an aqueous solu tion of a polymer containing quaternized amino groups, preferably one derived from an amino-acrylic monomer; and
    iii) drying the wool to a chosen moisture level in the range 12% to 18% by weight on the weight of the dry wool, using at least 20% less energy than is required to dry to the same moisture level wool which has been rendered shrink-resistant by conventional continuous processes.
