Abstract
We have studied in detail the color change of interlining-use nenwovens, and it was cleared that the color change of nonwovens is induced almost by the chemical change of their binders.
In our experiments, several kinds of latices were used as main agent and as the auxiliary agents the melamine condensate and its hardening catalyst.
Among these latices, for example, butadien-acrylonitrile, butadiene-strene, butadiene-metylmetacrylate and acryic ester polymers, such components as butadiene and acrylonitrile have considerable effects on the discoloration of nonwovens.
As regards the auxiliary agents, Sumitex ACX i, e., the hardening catalys, also has some effect on the discoloration, and that the cause of color change is due to the organic amine N contained in ACX.
