Abstract (en)
[origin: EP0683251A1] 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<1>2R<2>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-CH< or R<1>R<2>N<+>< Z<->; B = -NH2, -NR<1>R<3> or -N<+>R<1>R<2>R<4> 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<1>, R<2>, R<4> = H, Me or Et; R<3> = 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.
