Abstract: The use of aqueous dispersions or water-dispersible polyamides obtainable by the condensation of (a) 40 to 94.8 mol % of a monoaminocarboxylic acid with 2 to 12 C atoms or its lactam, (b) 2.6 to 37 mol % of a diamine with 2 to 18 C atoms, (c) 2.6 to 7 mol % of a dicarboxylic acid substituted with sulphonate groups and (d) 0 to 30 mol % of a dicarboxylic acid with 2 to 16 C atoms differing from (c), and dispersing the condensates in an aqueous medium, as sizes for warp yarns.

Abstract: The process involves… a) condensing aromatic dicarboxylic acids or esters thereof with at least one diol to give prepolymers having an acid number of from 2 to 8,… b) reacting the prepolymers with at least one molecular-weight-increasing compound, for example trimellitic anhydride, to give polyesters having acid numbers of from 40 to 60, and… c) dispersing the polyesters by adding aqueous mixtures of ammonia and amines in a molar ratio of from 10:1 to 1:10 to give a polyester melt which has a temperature in the range from 150 to 210 DEG C. … The polyester dispersions are used as sizes or sizing filament warp thread.

Abstract: A process for sizing staple fiber yarns by applying an aqueous sizing liquor which contains an alkaline earth metal salt of a copolymer containing from 90 to 30% by weight of acrylic acid and/or methacrylic acid and from 10 to 70% by weight of acrylonitrile and/or methacrylonitrile, which copolymer has a viscosity of from 50 to 1,000 cp in 15% strength aqueous solution at 85.degree.C, and drying the treated yarns. The sized films obtained are moistureinsensitive and have good heat stability.

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.
