    Abstract: Keratinous textiles are subjected to (1) treatment with an aq. soln. of a chlorocyanuric acid or its salt, followed by dechlorination (opt) washing and drying; and (2) after treatment with a dispersion of a polymer based at least on one acrylic acid ester. This process is improved in that the amt. of active chlorine virtually acting in stage (1) does not exceed 1.6 wt.% w.r.t. the weight of the textile material; this stage lasts for 1-10 secs. at a nearly neutral pH. Stage (2) comprises impregnation with an aq. dispersion of a reactive film-forming copolymer derived e.g. from a (meth) acrylic acid amide and contg. N-methylol gps. or their ethers, and an acetylising catalyst. Drying and fixing is effected by thermal treatment at 80-120 degrees C. The conditions of the whole process are very mild so that keratinous fibres are not damaged; in fact, their strength is increased and there is no tendency to yellowing. The process can be carried out continuously.

    Abstract: Process for printing textile materials made of cellulose fibres or their mixtures or blends with synthetic fibres with disperse dyes by the discharge resist process. The textile materials are pretreated with a liquor which contains an N-methylol or N-methylol ether compound of urea, urea derivatives or carbamic esters in solution, or they are printed uniformly with a print paste which contains one of said compounds, a dischargeable disperse dye and a synthetic thickener.
