Zusammenfassung: | The invention relates to a method for the treatment of, in particular, cellulose-containing textile fabrics, comprising the following steps: a) desizing the textile fabric or goods with aqueous treatment liquors, containing a combination of one or several known dispersants (i) and/or one or several complexing agents (ii), followed by washing out and rinsing, b) bleaching the fabric or goods, preferably with peroxide, whereby between steps a) and b) no heating of the textile material with alkali must occur, c) introduction of the size/water mixture obtained in a) to an ultrafiltration and separation of the same into a concentrated size solution and process water and d) re-introduction of the size solution obtained in c) into a sizing process preceding step a), optionally with further purification of the size and/or addition of fresh size. |
