摘要

Today the demands on PA textiles have become incomparably more strenuous than in the past, whether in terms of fashions and colours, heavy-duty use or more frequent and more intensive washing and cleaning. Here the fastness properties involve not only the dyestuffs but are now more and more dependent on the changed PA fibers themselves. The clear shift of production from PA 6.6 to PA 6 with lower kinetics and the increased number of fibrils coupled with simultaneously heavier delustring now allow only partially satisfactory wet fastness properties to be achieved with the currently available acid dyes, which also show limits in the dyestuff build-up.
