Abstract
A dyed textile article treated with tannic acid and dyed with an extract of mycelia or basidiocarps of Ganoderma lucidum. This article is produced by a process comprising contacting a substrate article of cotton, linen, silk or wool first with a pretreating bath containing tannic acid or a natural material containing tannic acid, e.g. gall, then with a mordant bath containing an alumina mordant, such as grass or wood ashes, and finally with the mycelia or basidiocarps of Ganoderma lucidum. This dyed textile article has not only a natural color and feeling, with a sufficient depth of color, but also antimicrobial and antiallergic functions.
