Abstract: Fabrics of which the warp is sized with water-soluble polymers of acrylic acid and/or their alkali metal salts or ammonium salts, are desized by treating the sized fabric with from 30 to 300 percent by weight of water, based on the dry weight of the fabric, and separating the resulting size solution from the fabric. The recovered size solution can be directly re-used for sizing.

Abstract: A process for dyeing cellulose fibers and mixtures of the same with synthetic fibers in an aqueous liquor by the exhaustion method in the presence of a water-soluble polymer of acrylic acid or an alkali metal salt or ammonium salt thereof, an alkali metal or ammonium salt of a copolymer of maleic acid and styrene, maleic acid and a vinyl ester or maleic acid and a vinyl ether as a dyeing assistant in an amount of from 0.05 to 2% by weight based on the material being dyed. Level dyeings are obtained and mixtures of fibers can be dyed in a single liquor.

Abstract: Polyester fibres or their mixts. with other fibres are dyed at over 130 degrees C, with addn. to the dye bath of at least one phthalate diester of a 6-20C aliphatic or araliphatic alcohol in emulsion form. Deposition of polyester oligomer as a powder on the fibre or on the equipment walls is prevented without reducing stability of the dye bath. In partic. ester of 8-15 C alcohols are used, in amount of 0.05-0.4 (0.1-0.3)% of the dye bath. They are emulsified using mixts. of anionic and non-ionic surfactants. The former is pref. an alkali or NH4 salt of a sulphate semi-ester of a 12-18 C alcohol or alkyl phenol reacted with 2-4 mols. ethylene oxide. The latter is pref. a 12-18 C fatty acid reacted with 5-50 mols. ethylene oxide (esp. on oleic acid deriv.), or castor oil reacted with 5-20 mols ethylene oxide per OH gp.
