S. Kobayashi et al., CHANGE IN COLOR OF DYED ARAMID FABRICS BY SPUTTER ETCHING, Journal of the Society of Dyers and Colourists, 111(4), 1995, pp. 111-114
The aramid fabrics Technora and Conex, dyed with Cl Disperse Yellow 54
, Cl Disperse Red 60 and Cl Disperse Blue 56, were treated with sputte
r etching and argon low-temperature plasma. The colour depth of Techno
ra was considerably increased by sputter etching, whereas that of Cone
x was not. Changes in colour were investigated by the L, C*, h colour
system. The increase in colour depth due to sputter etching was great
ly dependent on the decrease of metric lightness L and the increase o
f metric chroma C.
