Dyeing Process of PSA/MPIA Blended Fiber

Article Preview

Abstract:

The dyeing process of Polysulfonamide (PSA)/poly-m-phenylene isophthalamide (MPIA) blended yarn is studied. By choosing suitable dyeing carrier and dyeing parameters, the optimum dyeing condition was determined as follows: cationic dye 2-3%(o.w.f.), carrier acetophenone 40g/L, sodium chloride 15g/L, pH value 4-5, dyeing at 140°C for 60 minutes and the liquor ratio 30:1.
