Abstract
Liquid ammonia treatment of the textile fabric has been studied before now in order to improve the softness of cotton fabric with regard to shape stability finish. Furthermore, we are studying now on an application of ammonia-gas treatment to textile finishing instead of liquid ammonia treatment. In this study, two kinds of silk fabrics were treated with ammonia-gas under atmospheric (0.098 MPa) and at pressures of 2, 4, and 6 kgf/cm2 which correspond to 0.196, 0.392 and 0.588 MPa respectively. After the treatment, shearing and bending hysteresis curves were measured with a KES evaluation system , and then shearing and bending modulus G, B, and the hysteresis width 2HG, 2HG5 and 2HB were obtained. Each parameter decreased obviously by the treatment, especially at a pressured condition. Therefore, it is clear that the ammonia-gas treatment is effective to improve the soft hand of the silk fabric.
