Synthetic fibers and synthetic fiber textile materials finished with mineral oil finishes, silicone oil finishes or both can be simultaneously stripped of these finishes and dyed in one liquor comprising as essential ingredients

Simultaneous finish-stripping and dyeing of synthetic fibers

Raw native fibers and textile products therefrom can be simultaneously washed and bleached in one liquor if the liquor has added to it a combination product of

Simultaneous washing and bleaching of native fibres and textile products

Iminodisuccinic acids of the formula ##STR1## the substituents of which have the meaning given in the description, are bleaching regulators in H.sub.2 O.sub.2 bleaching of textile-forming natural plant fibers or silk, wool and their mixtures with synthetics.

Process for the pretreatment of fibers

Mixtures of various starch-degrading enzymes (amylases) which comprise at least one high temperature amylase (HTA) and at least one low temperature amylase (LTA) in an activity ratio of HTA to LTA of 10%:90% to 90%:10% develop at least 60% of their maximum activity in the temperature range from 30.degree. to 90.degree. C. Such mixtures can be diluted with water and treated with customary additives. These mixtures are suitable for desizing textiles sized with starch by treatment of the textiles with the mixtures mentioned and subsequent rinsing.
