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

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

Use as cellulose cross-linking agents of derivatives of alkanepolycarboxylic acids corresponding to general formula I: ##STR1## in which: n, m=0 or 1,

Alkanepolycarboxylic acid derivatives as cross-linking agents of

Amino-plastic resins soluble in water of which the nitrogenous derivative is chosen from the group comprising urea, 1,3-dimethyl-urea, ethyleneurea, 4,5-dihydroxy-ethyleneurea or their mixtures and the aldehyde derivative is a mixture of from 1 to 99% by weight of glyoxal and from 99 to 1% by weight of glyoxal monoacetal of formula (RO).sub.2 CH--CHO; R=C.sub.1 -C.sub.4 alk, their ethers and their applications in particular with cellulosed fibre treatment.
