    Abstract: Modified cellulosic synthetic fibres (I) are obtd. by: (a) treating a cellulose soln. with a modifier, and then (b) spinning fibres from the soln.; or by: (a) treating an alkali cellulose soln. with a modifier, then (b) xanthogenic treating and spinning fibres by the viscose process. The modifier is an amine of formula (1a), (1b), (1c), (1d) or (1e), or 2-oxo-1,3-oxazolidine, 4- or 5-aminomethyl-2-oxo-1,3-oxazolidine, 4- or 5-(trimethylammonium-methyl)-2-oxo-1,3-oxazolidine chloride, or 1-(trimethylammonium-methyl)-ethylene-carbonate chloride. (B)p-alk(OH)n(ER)m (1b) H2N-alkylene-(ER)m (1c) ClCH2-CH(OH)-CH2-N R 2R Z (1e) Z = H, 1-4C alkyl (opt. substd. with 1 or 2 OH gps.), or alkyl-(ER)m-; ER = ester gp.; A + N + 1 or 2 1-4C alkylene gps. = an heterocyclic ring; A = O, R-N R N ; B = -NH2, -NR R or -N R R R Z ; R = H, amino, 1-6C alkyl (opt. substd. with 1 or 2 amino, sulpho, OH, sulphato, phosphato or COOH gps.), or 3-8C alkyl with 1 or 2 in-chain O or NH gps. (opt. substd. as before); R , R , R = H, Me or Et; R = Me or Et; Z = anion; alkylene = 2-6C opt. branched alkylene (opt. substd. with 1 or 2 OH), or 3-8C alkylene with 1 or 2 in-chain O or NH gps.; Alk = 2-6C opt. branched alkylene, or 3-8C alkylene with 1 or 2 in-chain O or NH; m = 1 or 2; n = 1-4; p = 1 or 2; in these cpds., the amino, OH and ester gps. may be on prim., sec. or tert. C atoms of the alkylene gps. Also claimed is a process for the prodn. of dyed or printed textile materials from cellulosic fibres modified as above, by: (a) weaving or knitting the modified fibre, and then (b) dyeing or printing the fabric obtd. with anionic textile dye(s) in the absence of additional electrolyte salts or alkali.

    Abstract: Production of dyeings by the inkjet printing technique on modified fiber materials using anionic textile dyes There is described a process for dyeing sheetlike fiber materials, in particular those made of or containing cellulose fibers, with anionic dyes, in particular those having fiber-reactive groups, which comprises applying an alkali-free and preferably low-electrolyte or completely electrolyte-free aqueous solution of the anionic dye by the inkjet printing spray technique to a fiber material which has been pretreated and modified with a compound that contains one or more primary, secondary or tertiary amino groups or quaternary ammonium groups, which amino/ammonium groups may be part of a heterocycle. There is generally no need for an aftertreatment by washing. The costly treatment of wastewaters resulting from the excess dyeing liquors otherwise obtained is eliminated. If fiber-reactive dyes are used, fixation by means of alkali is not necessary; it is generally effected by a short heat treatment.
