Abstract

The objective of this paper is to measure the deposition of solid impurity on finished cotton fabric treated with DMDHEU resin during washing cycles of cotton fabric treated with different softeners. Fabrics will be softened with the conventional esterquat and with aminosilicone products having different molecular weights and mixtures of both. The anionic surfactant sodium dodecyl benzene sulphonate and non-ionic surfactant ethoxylated fatty alcohol were used. Both separately and in different proportions during the deposition trials were used. In general, the deposition values decrease on increasing the quantity of non-ionic surfactant in the mixture and with the finished cotton fabric increase this one after the application of the softeners tested alone and with their mixtures.

Kurzfassung

Das Ziel dieser Arbeit ist es, die Ablagerungen von festen Verunreinigung auf gefinishte, mit DMDHEU-Harz behandelten Baumwollgewebe während der Waschzyklen von mit verschiedenen Weichmachern behandelten Baumwollgeweben zu messen. Die Gewebe werden mit einem konventionellen Esterquat, mit Aminosilikonen, die sich in ihrem Molekulargewicht voneinander unterscheiden, und mit Mischungen aus Esterquat und Aminosilikonen weichgespült. In den Ablagerungsversuchen werden Natriumdodecylbenzensulfonat als anionisches Tensid und ein Fettalkoholethylenoxid als nicht-ionisches Tensid jeweils separat als auch in Mischungen mit unterschiedlichen Verhältnissen eingesetzt. Generell nimmt die Ablagerung mit zunehmender Menge an nicht-ionischem Tensid in der Mischung ab und bei dem gefinishten Baumwollgewebe nimmt diese nach Anwendung der untersuchten Weichspüler allein und in ihren Mischungen zu.
