    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: Mixtures of various starch-degrading enzymes (amylases) which comprise at least one high temperature amylase (HTA) and at least one low temperature amylase (LTA) in an activity ratio of HTA to LTA of 10%:90% to 90%:10% develop at least 60% of their maximum activity in the temperature range from 30.degree. to 90.degree. C. Such mixtures can be diluted with water and treated with customary additives. These mixtures are suitable for desizing textiles sized with starch by treatment of the textiles with the mixtures mentioned and subsequent rinsing.

    Abstract: In addition to the very time-consuming enzymatic and hydrolytic desizing processes, oxidative degradation of starch size by means of persulfate, to render the starch water-soluble, is conventionally practised. Because of the chemical similarity between starch and cellulose, oxidative degradation of the cellulose is unavoidable in this desizing process. The invention overcomes this problem by breaking up the macromolecules of the starch into dispersible fragments by means of such small amounts of persulfate that neither is the starch made water-soluble nor is the cellulose significantly damaged, the dispersants employed for the fragments being relatively oxidation-stable polymers of unsaturated carboxylic acids.

    Abstract: There are disclosed graft polyesters useful as adhesives and coatings and especially useful in processes for sizing spun and continuous filament synthetic organic and inorganic fibrous yarn. One embodiment of the invention is a textile size composition having free carboxyl groups which is prepared in situ on a textile yarn by the application of heat or radiation to a mixture of an unsaturated polyester reactant and a monovinyl monomer reactant comprising an acidic monovinyl monomer having at least one carboxyl group or mixtures thereof with any monovinyl monomer. Desizing can be accomplished by partial neutralization of the size to a pH of at least 6 by reacting the size with a base to render the graft polyester water-dispersible or water-soluble.The graft polyester compositions of the invention are especially useful as size compositions since they can be applied to the yarn from a solventless mixture and require only at least one of the application of heat or irradiation to graft polymerize the size in situ on the yarn. The graft polyester of the invention comprises the reaction product of (1) an unsaturated polyester which is the reaction product of at least one polycarboxylic acid reactant, preferably a dicarboxylic acid reactant and at least one polyhydric alcohol reactant, preferably a diol, wherein a minor effective proportion of at least one of said reactants is .alpha.,.beta.-ethylenically unsaturated with (2) at least one monovinyl monomer reactant comprising at least one acidic monovinyl monomer containing at least one carboxyl group or a mixture of said vinyl monomer with any monovinyl monomer.Alternatively, where water-insolubility is desired in the graft polyester under both acid and basic conditions, a polyunsturated vinyl monomer is utilized having two or more vinyl groups per molecule. The graft polyesters of the invention prepared using monovinyl monomers also can be reacted with cross-linking resins, such as aminoplast resins, to confer water-insolubility under both basic and acid conditions.
