Process for finishing a textile and finishing baths

Use as formaldehyde collectors of the products of formula ##STR1## in which R represents an acetoacetyl or 3,5-dioxo hexanoyl group, R.sub.1 represents a hydrogen atom or a methyl radical, m is equal to 1, 2, 3 or 4 and n is either equal to 1 when R.sub.1 represents a methyl radical or equal to 1, 2 or 3 when R.sub.1 represents a hydrogen atom, and finishing process for fabrics based on cellulose fibers using an aminoplastic resin containing formaldehyde in the free or combined state, using a product of formula (I) as the formaldehyde collector.

Use of polyalkyleneglycol diesters as formaldehyde collectors and

Tris(2-acetoacetoxy ethyl)-amine, and its hydrosoluble mineral or organic acid salts, preparation process, use as formaldehyde collectors, and finishing process for fabrics based on cellulose fibres.

Tris (2-acetoacetoxy ethyl)-amine, and its hydrosoluble salts,

Process for finishing a textile in which the textile to be treated is impregnated using a finishing bath containing phosphinicosuccinic acid (I), phosphinicobissuccinic acid (II) or a mixture of phosphinicosuccinic acid (I) and phosphinico-bissuccinic acid (II), finishing bath, finished textile and use of previously-mentioned acids as textile finishes or as cross-linking agents for cellulose.

Finishing process for textiles, finishing bath for textiles using

They have the formula: ##STR1## where either R.sub.1 and R.sub.2 are identical and represent --CH.sub.2 R where R=H or a C.sub.1 to C.sub.4 alkyl group or R.sub.1 and R.sub.2 together form the --CH.sub.2 (CR.sub.4 R.sub.4).sub.n --CH.sub.2 group where n=0 or 1, R.sub.4 =H or --CH.sub.3, R.sub.3 =H or --CH.sub.2 R.sub.5 where R.sub.5 =H or a C.sub.1 to C.sub.4 alkyl group. A and A.sub.1 are either identical and represent H or A and A.sub.1 together form an ethylene, trimethylene or --CH(OCH.sub.2 R.sub.6)--CH(OCH.sub.2 R.sub.6)-- radical where R.sub.6 =H or a C.sub.1 to C.sub.4 alkyl group or, when R.sub.3 =H, a 1,2 dihydroxy-ethylene group. They are obtained by reacting a disubstituted ethanal ##STR2## with a urea ANH--CO--NHA, followed if required by etherification with an alcohol R.sub.5 CH.sub.2 OH.
