摘要:
Process for producing pattern effects when dyeing or printing textile material in the absence of alkali or reducing agents, which comprises pretreating the textile material with a cationizing agent, drying, applying an oxidizing agent in the form of a pattern, drying and dyeing or printing with reactive, direct, acid, water-soluble sulfur dyes or pigment dyes in the absence of any alkali or reducing agent.

摘要:
Perfluorinated vinyl ethers are prepared by reacting a fluorinated carboxylic acid fluoride with hexafluoropropylene epoxide in the presence of a catalyst and thereafter pyrolyzing the carboxylic acid fluoride containing ether linkages, optionally after having converted it into a salt of a monovalent metal.
摘要:
Perfluoro carbonyl compounds react with hexafluoro propene epoxide in the presence of dimethylamino-difluoro-phosphorane producing perfluorinated carboxylic acid fluorides with ether linkages. Among the carbonyl compounds which can be used are perfluorinated ketones, acid fluorides of the formulaR.sub.F -- COF and R.sub.F -- OCF(CF.sub.3) -- COF(r.sub.f being a perfluoro-alkyl radical having from 1 to 4 carbon atoms) and perfluoro-2-oxo-3,6-dimethyl-1,4-dioxane.
摘要:
Stable and homogeneous aqueous formulations of surfactantsStable and homogeneous aqueous formulations of surfactants having an HLB value of less than or equal to 13, which additionally contain a compound of the formula I ##STR1## in which R.sup.1 is C.sub.1 -C.sub.8 -alkyl, C.sub.1 -C.sub.8 -alkenyl, phenyl, alkylphenyl or phenalkyl having in each case 1 to 4 carbon atoms in the alkyl chain or cyclohexyl, R.sup.2 is hydrogen or one of the radicals mentioned for R.sup.1, or R.sup.1 and R.sup.2, together with the nitrogen atom, are a heterocyclic radical, M is an alkali metal cation, an ammonium cation or one equivalent of an alkaline earth metal or aluminium cation and m and n in each case independently of one another are numbers from 6 to 8.By the presence of the compounds of the formula I, it is possible to prepare stable and homogeneous aqueous formulations even from those surfactants which are otherwise only sparingly soluble or not soluble at all in water.
摘要:
Water-soluble sulphur dyes can be applied to cellulose without reducing agents, without added salt and without oxidising agents if the cellulose has been grafted with a polymer obtained by polymerisation of at least one N-containing basic monomer.
