アミノアントラキノン型分散染料による染色ナイロンの帯電性

抄録

Purified anthraquinone disperse dyes having the substituent group such as amino or methylamino were used to study the static electrification of dyed nylon fabrics.
The dyeing was carried out in water at 85°C for 2-hours. Surface resistivity, charge generation, half-decay time of charge and moisture content were measured in atmosphere at 20°C, 50% RH. The measured values were compared with the amount of the dye absorbed and the relation among them were investigated.
As a result of measurement, surface resistivity and half-decay time of all dyed fabrics increased comparing with those before dyeing.
It was found that there is a good correlation between surface resistivity and half-decay time of charge.
