Study on the Dyeing Behaviors of Low Temperature Glow Discharge Treated Wool

Wool tops was modified by low temperature glow discharge (LTGD). The inputted power, the treating time and the pressure or vacuum were found to play an important role. The wool tops were dyed with reactive dye under a constant dyeing temperature after plasma treatment. Then the dyeing behaviors were studied based on the data of uptake, fixation, dyeing rate and fixing rate. The results revealed the possibility of low temperature dyeing and the suitable parameter of LTGD treatment.     

Study on Polypropylene Film Treated by Low Temperature Glow Discharge

The results of contact angle and X-ray photoelectron spectrometry (XPS) reveal the effects of plasma treatment. The treated polypropylene film shows improved wet ability. Comparing the different treating conditions, such as time and atmospheres, the results reveal that there may exist two parallel reactions. And the different atmosphere has the different action in plasma treatment also.
