    Abstract: Printed textiles, partic. prints with reactive dyes on cellulose fibres, disperse dyes on synthetic fibres and mixtures of these dyes on cellulosic/synthetic blend fabrics, are after-treated by washing with a compsn. contg. a copd. of formula R2CO-(OC2H4)n -O-C4H8-O-(C2H4O)m-OCR2 (where R1CO- and R2CO- are acyp gps. of 12-22 (16-20)C n- or iso- alkanoic or alkenoic acids and n and m are 4-12 (6-9)), opt. in combination with hydroxyethylated naphthols of formula: (where x is 0 to 4) and adducts of CH2CH2O to castor oil. Printed polyester/cellulosic blend fabrics are pref. after-treated by adding pt. of compsn. to printing dyes, opt. with addn. of orthoboric acid, and remaining compsn., after fixing, to after-treatment bath.

    Abstract: Causticisation-based local crimp (curl) effects together with identical colour patterns in the piece can be obtained by using reactive dyes in the crepe resist (reserve) which constitutes a combination of mixtures of reactive polysiloxanes with self-crosslinking copolymer dispersions based on acrylate or butadiene. And the effectiveness of such a specific coloured crepe resist, applied as first print (preprint), is at the same time successfully utilised as a mechanical dye resist for subsequent overlappingly applied ground pastes (colours) composed of reactive dyes. By further addition of chemical resisting agents to the crepe resist the attainable colour effects are made still more varied in the cross-dyeing (over-dyeing).

    Abstract: Process for the fixation of prints with reactive dyestuffs, wherein an aqueous alkaline bath which contains an inflammable organic liquid is applied onto the printed and dried material, the said organic liquid is burned off after passage of the material through air and the said material is further treated in the usual manner. This process has the advantage, in addition to the usual advantages of a continuous method of operation over a discontinuous method, that special steamers for the fixation are not necessary. The burning off process is effected in an essentially simpler apparatus, in the most simple case a burning-off duct is sufficient. Moreover, the new process requires less energy than the conventional fixing processes.

    Abstract: The production of discharge resists on synthetic fibres in carpet printing with disperse dyes usually fails because, as a consequence of the structural constitution of the material, application of the aqueous print colours for the ground coloration results, owing to the high add-on levels required, in more or less smudged contours for initially or subsequently applied discharge resists and untidy products. According to the invention, these undesirable phenomena can be remedied by applying the ground colours in foamed form to the pile goods to be patterned by means of alkaline discharge resists.
