Color Depth of Polyamide Fabrics Pretreated with Low-Temperature Plasma under Atmospheric Pressure

상압 저온 플라즈마 전처리한 폴리아미드계 직물의 색농도

Wool, silk and nylon 6 fabrics were treated with low-temperature plasma under atmospheric pressure of acetone/argon or helium/argon for 30 and 180 sec, and then dyed with leveling type acid dye, C.I. Acid Red 18 and milling type acid dye, C.I. Acid Blue 83. In spite of short time of the plasma treatment for thirty seconds, the color depth of wool fabrics was increased remarkably with both of the plasma gases, aceton/argon or helium/argon and with the kinds of dyes i.e., levelin type or milling type. But the atmosperic low-temperature plasmas did not increase the depth of silk and nylon 6 fabrics dyed with both of the acid dyes regardless of the teated time and plasma gases. It seems that low-temperature plasma by atmospheric-pressure discharge is effective for improvement of dyeing of wools as is the same way with the low-temperature plasma by glow discharge. The kinds of plasma gases and treated time did not influnce the depth of wool fabric pretreted with the atmosperic low-temperature plasmas.
