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.
