Waschverfahren für Textilien mit verbesserten Pflegeeigenschaften

摘要

Even high-grade textiles like silk, viscose or wool can be carefully washed by machine by the use of a foaming powdered to granular washing agent with an apparent density of 300 to 1000 g/l, containing one or more highly foaming tensides, especially alkyl glycosides and/or low-ethoxylated alkyl ether sulphates in quantities such that, when used in a concentration of 2.5 to 8 g/l at washing temperatures of 60 DEG C at most, the agent forms a foam which, measured by the SSF method, meets the stability critera: (1) no holes occur in the foam column with samples in the useful concentration range from 2.5 to 8 g/l (water hardness 16 DEG d, temperature 16 DEG C); (ii) the foam column has a height of at least 30 cm and at the most 40 cm after 120 seconds' foaming time; (iii) the theoretical foam height after the application of a 50 g weight is no less than 28 cm, where the difference between the maximum foam height a fter 120 seconds and the theoretical foam height is less than 4.3 cm, and/or (iv) the drop in the foam height per unit time after the application of the weight is less than 2 cm per minute.
