The present invention is directed to durable finishes for cellulose-containing fibers and fibrous substrates. The active components of the finishes are hydroxyl-containing amines, and preferably trialkanol amines. When combined with a suitable crosslinker, the amines become attached to and crosslinked on the substrate fiber, and form a soft resinous coating that is durable to cleaning procedures. This polymeric coating imparts durable anti-microbial activity and renewable control of certain odors.

Cette invention se rapporte à des apprêts durables pour fibres et substrats fibreux contenant de la cellulose. Les constituants actifs de ces apprêts sont des amines en teneur en hydroxyle et, de préférence, des amines de trialcanol. Lorsqu'elles sont combinées à un agent de réticulation approprié, ces amines se fixent par réticulation sur la fibre du substrat et forment un revêtement résineux mou qui résiste durablement aux nettoyages. Ce revêtement polymère confère à la fibre une action antimicrobienne durable et un effet renouvelable de lutte contre certaines odeurs.
