Abstract
Cellulosic textile materials are creaseproofed by a process comprising (1) treating them with an aqueous composition containing a synthetic resin precondensate capable of condensing under acid conditions to effect cross-linking of the textile material, (2) drying them at a temperature below the condensation temperature of the precondensate and (3) treating them with aqueous sulphuric acid at a concentration and for a time so that partial condensation is effected bonding a number of reactive groups of the resin to the textile materials whilst leaving a substantial number of free reactive groups of the precondensate in an unreacted state. The finishing of the textile materials may then be completed for example by the steps of (4) shaping, e.g. pleating, or making up the textile materials and (5) heating them in the presence of a condensation catalyst, e.g. Mg Cl2, NH4 Cl, (NH4) H2 PO4, Zn Cl2 and Zn (NO3)2 to complete condensation. The condensation catalyst necessary in step (5) may be applied to the textile material after step (3) but before step (4). The resin precondensate may be condensation product of formaldehyde and a p nitrogenous compound, e.g. urea, thiourea, a cyclic urea having a 5- or 6-membered heterocyclic ring system, acetylene diurea, a carbamate or melamine. The textile material may be padded with an aqueous solution of the resin precondensate, dried, treated with an aqueous sulphuric acid bath containing 40-60% by weight of sulphuric acid for 0.5-30 minutes, neutralised with a dilute caustic soda solution, rinsed, dried, made up into garments, padded or sprayed with an aqueous solution of the condensation catalyst and heated at 120 DEG -180 DEG C for 1-10 minutes to complete condensation. Step 5 may be carried out in the presence of a small quantity of at least one compound capable of reacting under acid conditions with the cellulose or with itself and the cellulose, e.g. acetals, epoxides, polyepoxides, halohydrins and condensation products of formaldehyde with Ketones, urea, thiourea, cyclic ureas having a 5- or 6-membered heterocyclic ring and their hydroxy or oxo derivatives, acetylene diurea, dicyandiamide, guanidine, carbamates and melamine or etherification products thereof. Yarns, fibres, filaments, threads or woven or nonwoven fabrics comprising natural cellulose, e.g. cotton, regenerated cellulose or cellulose derivative fibres, e.g. cellulose acetate, alone or in admixture with other natural or synthetic fibres, e.g. polyester fibres, may be treated.
