Process for dyeing or printing fiber materials containing hydroxyl groups, characterized in that at least one blue-dyeing dyestuff of the formula ##STR1## wherein the substituents have the meaning given in the description, is used together with at least one yellow-dyeing and/or at least one red-dyeing and/or at least one navy blue- or black-dyeing dyestuff.
摘要:
Azo class reactive dyestuffs have been found which have the general formula (1) ##STR1## and in which Z.sup.1 and Z.sup.2 represent a reactive group from the pyrimidine series, X represents SR.sup.1, OR.sup.2 or NR.sup.3 R.sup.4, and the remaining substituents have the meanings given in the description, which dyestuffs are particularly suitable for dyeing hydroxyl- and amido-containing fibres, in particular cotton.
摘要:
Improved reactive dyestuff red mixtures comprise in each case at least one component of the formula 1 ##STR1## and one component of the formula 2 ##STR2## wherein the substituents have the meaning given in the description.
摘要:
The invention comprises a gasification reactor which comprises a vessel having at its upper end a downwardly directed burner and a combustion chamber located in the upper half of the vessel. The wall of the combustion chamber comprises an arrangement of interconnected parallel arranged tubes running from a common lower arranged distributor to a higher arranged common header. The distributor is connected to a cooling water supply conduit and the header is connected to a steam discharge conduit. Both the steam discharge conduit and the water supply conduit are fluidly connected to a steam drum. The steam drum is provided with a supply conduit for fresh water and the steam drum is positioned at a higher elevation than the common header.
摘要:
Gasification reactor vessel, comprising a combustion chamber in the upper half of the vessel, provided with a product gas outlet at the bottom end of the combustion chamber, a burner positioned such that, in use, it fires into the combustion chamber, said burner provided with at least supply conduits for an oxidiser gas and a carbonaceous feed, wherein between the wall of the combustion chamber and the wall of vessel an annular space is provided, and wherein the wall of the combustion chamber comprises an arrangement of interconnected tubes (vertical arranged or helical coiled), and wherein two burner openings are present in the wall of the combustion chamber, which burner openings are located at the same horizontal level and are positioned diametrical relative to each other and wherein in the burner opening a burner is present.
摘要:
A phthalocyanine reactive dyestuff mixture having an improved dyeing levelness and combination properties comprises at least one phthalocyanine vinylsulphonyl reactive dyestuff 1, at least one phthalocyanine fluorochloropyrimidinyl reactive dyestuff 2 and/or a phthalocyanine monochlorotriazinyl reactive dyestuff 3.
摘要:
Azo dyes are obtained by diazotizing an aromatic amine and combining the resulting diazonium salt solution with a sulpho-containing coupling component when the sole acid donor used for the diazotization reaction--instead of the otherwise customary mineral or fatty acids--is a low molecular weight, nonsurfactantlike aromatic sulphonic acid.
