    Abstract: Cellulose-containing fabric is desized by treating with an enzyme hybrid having a catalytically active amino acid sequence of an enzyme such as a lipase or an amylase linked to an amino acid sequence containing a cellulose-binding domain. The enzyme amino acid sequence may be of an .alpha.-amylase obtainable from a species of Bacillus such as Bacillus licheniformis, or of a lipase obtainable from a species of Humicola, Candida, Pseudomonas or Bacillus. The cellulose-binding domain may be from a cellulase, a xylanase, a mannanase, an arabinofuranosidase, an acetylesterase or a chitinase. The enzyme hybrid is obtained from a transformed host cell containing an expression cassette having a DNA sequence encoding the enzyme hybrid. A desizing composition is formed containing the enzyme hybrid and a wetting agent.

    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 polyunsaturated 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.

    Abstract: Non-aqueous, quick setting sizing compositions suitable for application as a melt to textile yarns, and for later removal by solvent or aqueous means, characterized by substantial amounts of hydrogenated tallow-type triglyceride wax, are disclosed. The compositions may include an approximately 50:50 weight mixture of a specific class of 80/20 ethylene/acrylic acid copolymers intimately blended with an equal amount of the wax. A fatty acid amide may be included in an amount up to about 7 weight percent of the composition or from 1 to 14 weight percent sebacic acid or dodecanedioic acid, the amount of copolymer being reduced accordingly. The compositions may contain up to 62 weight percent of the wax, and rigidify at ambient temperatures.

    Abstract: A process for desizing and cleaning fabrics and garments which produces a substantially desized fabric or garment while holding the dye that is removed from the garment in suspension in the bath is disclosed. The process includes the steps of immersing the woven fabric or garments in an aqueous bath containing from about 1.0% to about 8.0% owg of a desizing agent and maintaining the fabric in the desizing bath for a time sufficient to desize the goods while minimizing the removal of dye present in the goods. The desizing agent includes from about 1.0% to about 100% by weight of the desizing agent of a clay and up to about 10% by weight of the desizing agent of at least one surfactant.
