Vorbehandlung von Textilien

摘要

Formulations (F1), preferably used for treating textile fibre material - contain glucose-free polymers (P1) prepared from acrylic acid and glucose-containing saccharides. Also claimed are the following: (i) formulations (F2) for treating textile fibre material; (ii) the preparation of (F1) and (F2) by treating (P1) or (P2) with glucose-oxidase; (iii) the preparation of (F2) in which the oligo and/or polysaccharides are hydrolysed before, during and/or after polymerisation to form enolisable saccharides in situ; (iv) the preparation of (F2) in which (P2) are formed by reacting acrylic acid with enolisable mono-, oligo- and/or polysaccharides at pH 7-10; and (v) a process for treating textile material, preferably cellulose fibres, with (F1) or (F2). Preferably (F2) comprises 2-30 parts by weight (P2) and 70-98 parts by weight additives. (P2) may be substituted with (P1). (A) are mono- or polycarboxylic acids (preferably citric acid, tartaric acid, lactic acid, gluconic acid and/or glucoheptonic acid), phosphonic acids (preferably HEDP, ATMP, DTPMP and/or HDTMP), mineral acids (preferably hydrochloric acid or sulphuric acid) or amidosulphonic acid. (B), (C) and/or (D) are present as surfactants. (B) are 8-20C fatty alcohol alkoxylates. (C) are 8-20C polyglycosides (n = 1-3). (D) are 8-20C alkane sulph(on)ates, 8-20C alkane carboxylates and/or 8-20C alkane ether carboxylic acids, or alkyl benzene sulphonates. (H) are amylases, catalases, cellulases, lipases, pectinases, proteases and/or glucose-oxidases. (F1) and (F2) have a pH greater than 11.5 and contain an additive system comprising 10-40 wt.% water glass (I), 0-20 wt.% chelating agent (J) and the balance water.
