During manufacturing process from raw materials to finished goods, wool fibers have been chemically and physically damaged and tended to be attacked by microorganisms. This article aims to study the method to retard or control the damages of the wool fibers by fungi. It deals with the antifungal effect of dyes for wool fibers such as acid dyes, acid mordant dyes and metal complex dyes.
It is found that several acid mordant dyes such as Chrome Cyanine FR and Chrome Black ET conc. prevented from growth of fungi on medium. It is also found that Irgalan Yellow GRL, which is one of the metal complex dyes, is effective for controlling the growth of fungi. Nevertheless, the dyed cloth normally shows the growth of fungi. But an excess of dyeing shows little loss in strength.
This article also deals with the condition of microbial damage by elctron microscopy examinations.
