Abstract
Polyester / Cotton (50/50, 65/35) fabrics were treated with liquid ammonia under practical conditions, followed by resin-finishing with nitrogen-contained glyoxal resin NS-19 (Sumitomo Chemical Co.). Nitrogen content, washing shrinkage, crease recovery angle, softness, and KES shearing and bending properties were measured. Nitrogen content of the NH3 treated cotton fabric after resin treatment is obviously decreased as the same behavior in dyeing with CI Direct Blue 1. Although washing shrinkage and crease recovery were diminished with the NH3 treatment, the shrinkage and crease recovery were decreased much more with an increase of polyester fiber content. KES shearing and bending parameters are also decreased with the NH3 treatment.
