摘要:
The aromatic formaldehyde condensation products, which are substantially colorless and water-soluble and contain sulphonate and/or carboxylate groups, are obtainable by adding agents which have a reducing action during and/or after the condensation reaction, and are suitable for the treatment of textiles and leather.
摘要:
Polyamide-containing fibre materials can be given an anti-stain finish by treating them with a sulpho-containing aromatic formaldehyde condensation product in combination with polyacrylic acid, the treatment with the two components being carried out in any desired order or simultaneously.
摘要:
The present invention relates to acid-resistant solutions containing aromatic formaldehyde condensation products having sulfonate and/or carboxylate groups, aliphatic carboxylic acids, aromatic sulfonic acids, and glycol ether solvents, to the preparation thereof, and to their use as leveling agents, dispersants or fastness improvers in textile finishing, as tanning agents for leather, and in the stain resist finishing of textile materials.
摘要:
Synthetic fibers and synthetic fiber textile materials finished with mineral oil finishes, silicone oil finishes or both can be simultaneously stripped of these finishes and dyed in one liquor comprising as essential ingredientsa) anionic and/or amphoteric surfactants,b) dyes, andc) optionally further compounds selected from the group consisting of the nonionic surfactants, the terpene hydrocarbons/alcohols, sorbitol esters and their alkoxylates, fatty acid ethanolamides, alkylpolyglycosides and solvents.The treatment is carried out at pH 4.0 to 7.5 at 80-110.degree. C. and at a liquor ratio of 5:1 to 100:1.
摘要:
Improved compositions for dyeing or printing textile materials of natural or synthetic fibers or mixtures of the two comprise polyaspartic acid or a derivative thereof and, if appropriate, wetting agents, emulsifiers, leveling agents, dispersing agents, reducing agents, oxidizing agents, solubilizing agents, defoamers, reist agents, pH regulators, complexing agents or several of these as further components.
摘要:
The present invention relates to novel liquid formulations for the controlled and sustained release of insecticidally active compounds by means of a heat source and the water-based pre-solutions required for preparing these formulations.
摘要:
A thickener composition for thickening aqueous compositions which contains a) a water soluble or water dispersible thickener containing urethane groups, b) a non-ionic aromatic or alkyl-substituted aromatic emulsifier and c) a compound corresponding to formula IR.sub.2 --�(Q.sub.2 --).sub.t H!.sub.u (I)wherein R.sub.2 represents an optionally branched and unsaturated aliphatic radical having 6 to 22 carbon atoms, a cycloaliphatic radical having 6 to 10 carbon atoms or a heterocyclic radical having 5 to 12 ring atoms, as obtained by removing the active hydrogen from a hydroxyl, amino, carboxylic acid or amide group, Q.sub.2 represents a C.sub.2 -C.sub.4 alkylene oxide unit, t has a value from 1 to 30 and u has a value from 1 to 10, and d) optionally further additives.
摘要:
.beta.-Hydroxyalkylpicolinium salts of the formula (I) ##STR1## wherein A, R.sup.1 to R.sup.3 and X have the meanings given in the description, which are obtained by reaction of picolines of the formula (II) ##STR2## with alkylene oxides of the formula (III) in the presence of a 1- to 3-basic acid and in water or an organic solvent as the reaction medium and are used as intermediate products for the preparation of cationic dyestuffs, and dyestuff preparations comprising such cationic dyestuffs.
摘要:
Dyed raw cellulose can be bleached in a bleaching and after-treatment bath containing, in addition to usual stabilizers, cationic-monomeric and/or polymeric compounds and, if desired, nonionic surfactants. Bleaching is carried out with the aid of aqueous-hydrogen peroxide. The stabilizers that can be used and the cationic compounds are defined in the specification. Nonionic tensides, if their co-use is desired, are those of the class polyglycolethers.
摘要:
Surface-active esters of aliphatic polyols containing at least 3 hydroxyl groups and aliphatic, cycloaliphatic or araliphatic acylaminocarboxylic acids, which contain a total of at least 8, preferably 12-60, carbon atoms and which are acylated by aliphatic carboxylic acids with 1-4 carbon atoms, aromatic or araliphatic carboxylic acids or aliphatic, aromatic or araliphatic sulphonic, carbonic or carbamic acids, are suitable as auxiliaries in the dyeing of textile materials.
