Effect of artificial perspiration solutions on the performance of silk Habutae

Abstract

In order to study the effect of artificial perspiration on the performance of the silk fabric (Habutae) after repeated extension, the fabrics treated with acidic and alkaline perspiration solutions and water were repeatly extended, and the performance such as shrinkage, elongation, extension strength, luster and whiteness was determined.
The shrinkage of the fabric treated with acidic or alkaline artificial perspiration solutiosns was about 5%, similar to the treatment of water alone. The extension strength decreased equally to that of water treatment.
The whiteness after fade-meter exposure for 72hrs lowered in the following order: untreated>treated with water>treated with alkaline perspiration>treated with acidic perspiration.
Even when the untreated fabrics and those treated with artificial perspiration were heated with plate (at 220, 230 and 240°C for 3min) and in air (at 150°C for 90min), there was almost no difference in yellowing of the fabrics by the treatment.
