    Abstract: O.Z. 0050/034411 A process for the preparation of a textile finish, the finish thus obtained and its use for the easy -care finishing of textiles containing, or consisting of cellulose. The finish comprises an aqueous solution, of from 30 to 70 per cent strength by weight, of a mixture of the conventionally methylolated (= hydroxymethylated) carbamates I and II I II where R is hydrogen or alkyl of 1 to 4 carbon atoms, in the weight ratio I : II of from 1 : 1 to 1 : 20. The finish is prepared by reacting a glycol or an alkylgylcol of the formula III R-(OCH2-CH2)9-100-OH III where R has the above meanings, and isobutanol with urea at above 100.degree.C, so as to eliminate ammonia and produce carbamates, and methylolation with formaldehyde. In a first stage, the glycol or alkylglycol of the formula III is reacted to the extent of at least 50% with urea, in the absence of a catalyst; at from 130 to 160.degree.C, to give the carbamate I, and in a second stage, carried out either in the presence of an ion exchanger containing nickel ion at from 130 to 165.degree.C, or in the absence of a catalyst at from 150 to 200.degree.C the carbamate mixture in the weight ratio I : II of from 1 : 1 to 1 : 20 is prepared by addition of isobutanol and further urea.

    Abstract: 1415206 Textile-treating urea-formaldehydeglyoxal resins BADISCHE ANILIN- & SODAFABRIK AG 2 March 1973 [3 March 1972] 10214/73 Headings C3R and C3P [Also in Divisions D1-D2] A textile-treating resin is obtained by condensing urea with formaldehyde in a 1 : 2-10 molar ratio in aqueous solution at pH 7-10 and 20-80‹ C. for 0À5-4 hours, then at pH 31-5 and 20-100‹ C. until 5 drops of the solution produce turbidity in 10 ml. of 50% aqueous MgSO 4 .7H 2 O, then adding urea, glyoxal and optionally formaldehyde and heating at pH 5-7 and 20-60‹ C. for 1-6 hours, the final molar ratio of urea : formaldehyde : glyoxal being 1 : 1À5-2À5 : 0À3-0À6. In Examples 1-4 initial condensates of U : F ratio 1 : 4 are acidified with H 2 SO 4 or H.COOH to pH 3À5 to 4À8, heated at 35-90‹ C. for 20 mins to 4 hours and neutralized with NaOH; urea and glyoxal (and in Ex. 4 formalin) are added and the mixture heated at 50-55‹ C. for 3-4 hours; the U : F : G ratios of the products are 1 : 2-2À24 : 0À4-0À5. In Examples 5-7 cotton fabrics are treated with aqueous compositions containing the product of Ex. 2 or 3 and MgCl 2 alone or with a polyethylene emulsion or polyvinyl acetate/ starch mixture.
