| Research Abstract |
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. In this work, we investigated reaction conditions between nylon fibers and various reducing sugars to prevent nylon fibers from turning yellow due to aromatic aldehydes. As a result, the reaction with reducing sugar in organic solvent or water solution containing sodium hydrosulfite prevented the nylon fibers most effectively from being changed not only to yellow by the reaction with vanillin, one of aromatic aldehydes, but also to brown by the melanoidin reaction as a side reaction.
