Anti-yellowing Finishing of Nylon Fiber Using a Reaction with Reducing Sugar

摘要

It is well known that nylon fibers turn yellow during long storage in wooden boxes or corrugated cartons, where the nylon fibers react with various aromatic aldehydes gradually generated from wood or crude paper. In general, in the textile fields, formaldehyde is a useful reagent to prevent nylon products from turning yellow, but it is also one of the main materials causing the sick building syndrome (SBS). In this paper, we investigated reaction conditions between nylon 6 fibers and various reducing sugars to prevent nylon fibers from turning yellow due to vanillin, which is one of the aromatic aldehydes. Furthermore, their other fiber properties, such as mechanical strength and hygroscopicity, were also examined.
