粘土鉱物による絹布の最適着色条件と成分分析

Abstract

As a result of analyzing for the components of clay minerals before and after coloration (XRF), it has been observed that the elements that are involved in colored silk are Fe, Cr, Ni and etc. Among them, Fe is proved to be the most important ingredient after coloration with an occupying ratio of 68%, and it turned out that Cr and Ni also have certain effects upon coloration. The optimal coloration condition can be made by repeating the process of immersing the silk fabric per 1 g in slurry of 8 g with clay mineral at 60 degrees C for 150 minutes and drying it for 24 hours, followed by rinsing it six times. As the repetition frequency of this coloration process increased, the (K/S) 410 value of both sample A and sample B has been increased from 0.9 to 2.1 and 0.9 to 1.9 respectively. The coloration in this experiment has been done four times. Thus, repetition of this coloration process is very significant. Especially both rinsing and drying process are important for raising coloration level. Also, this study showed that, under the optimum condition of fabric coloration with clay, excellent results could be expected for the tests of rubbing, color fastness to light, perspiration, and antibiotic.
