摘要:
Textile cellulose material is printed or dyed with reactive dyes with the aid of foam. The foam is applied by applying to the cellulose material a foamed, aqueous preparation which contains in addition to dyes and fixing alkalis(1) a foam-forming agent(2) a homopolymer or copolymer of acrylamide or methacrylamide or preferably a graft polymer which is obtained from an addition product of an alkylene oxide, preferably propylene oxide, on an at least trihydric aliphatic alcohol, e.g. glycerol, and acrylamide or methacrylamide, and(3) an anionic graft polymer which has as grafting base a copolymerization product from (A) an alkyl acrylate or methacrylate, the alkyl radical having at least 8 carbon atoms, with (B) a dicarboxylic acid diester of an ethylenically unsaturated aliphatic dicarboxylic acid and a polyethylene glycol, a terminal hydroxyl group of the diol having been etherified with a C.sub.1 -C.sub.4 -alkyl radical, and contains as graft constituent side chains which stem from grafted-on polymerizable monomers which contain hydrophilic groups.The cellulose material thus treated is then subjected to a heat treatment, for example steaming, to fix the dye.This very stable preparation produces without the use of thickenings a strong, level and crisp print which at the same time has an excellent handle.
摘要:
Cellulosic textile material is dyed with substantive dyes or preferably with reactive dyes. Dyeing is carried out by applying to the cellulosic material an aqueous dye liquor which contains, in addition to the dye, a graft polymer which is obtained from an adduct of an alkylene oxide, preferably propylene oxide, with an at least trihydric aliphatic alcohol, e.g. glycerol, and acrylamide or methacrylamide. The cellulosic material is then subjected to a heat treatment, e.g. by steaming or with microwaves, or is stored cold, to fix the dyes.This dye liquor increases the liquor pick-up and thus also increases the dye yield, while at the same time excellent levelness is achieved.

Copolymers which are obtainable from(1) 20 to 50% by weight of an N-substituted or N-unsubstituted acrylamide or methacrylamide and(2) 50 to 80% by weight of an N-vinyl-substituted amide or of a vinyl ester, derived in each case from a saturated aliphatic monocarboxylic acid,the sum of (1) and (2) adding up to 100%.These novel copolymers are suitable as dyeing assistants, particularly as padding assistants or liquor binders in the dyeing of cellulose fibre materials.

Oligomers of the formula ##STR1## wherein Y.sub.1 is hydrogen or --CO--T.sub.1, R.sub.1 Q.sub.1 and T.sub.1 are alkyl and n.sub.1 is 1 to 16, or alkali metal salts thereof, are used as stabilizers in peroxide-containing alkaline liquors for bleaching cellulosic fibre materials.
摘要:
A process for dyeing or printing organic fibrous material made e.g. of polyamide, polyester or polyacrylonitrile, and also of cellulose, said process comprising the use of a dyeing or printing assistant which contains a quaternary ammonium salt. The salt is a reaction product of a copolymer of maleic anhydride and ethylene, propylene or styrene, with a N,N-disubstituted n-alkylenediamine, a homopolymer of a vinylpyridine, or a quaternized copolymer of a vinylpyridine and styrene. The reaction product, the homopolymer, and the copolymer are quaternized with e.g. benzyl chloride. The ammonium salt can also be a homopolymer of a vinylbenzyl chloride which is quaternized with a tertiary monoamine. The fibrous material dyed or printed with e.g. direct or disperse dyes or with cationic dyes has excellent levelness, good penetration of the dye, and good wetfastness properties. It is also possible to obtain multi-shade effects by printing the material patchwise with a reserve paste and then dyeing it.
摘要:
Acid esters of propylene oxide poly-adducts and their salts, which are obtained by an addition reaction of(a) propylene oxide with(b) a polyfunction amine, which contains 2 to 9 carbon atoms and at least a second reactive amino group or at least one hydroxyl group, and esterification of the poly-adduct with(c) an oxy-acid which is at least dibasic or with a functional derivative of this acid and, if appropriate, by conversion of the resulting acid ester into a salt.These acid esters of propylene oxide poly-adducts are particularly effective as dyeing auxiliaries, especially as dispersing and levelling agents for dyeing synthetic fibres and primarily for dyeing linear polyester fibres.
