| 초록 |
Cellulosic fabrics, i.e. rayon, polynosic, and linen were treated with liquid ammonia at -33.4. The fine structures, bending properties, tensile strength, wrinkle recoveries, and dyeing properties of the treated fabrics were studied. Dyeing was carried out with two direct dyes, C. I. Direct Red 2 and Blue 1. The liquid ammonia treatment for three fabrics brought about the transition of crystal lattices and the decrease of crystallinity; transforming cellulose I structure of original linen to cellulose I and III structure, and cellulose II structure of original rayon and polynosic to cellulose II and III structure. Moisture regain of liquid ammonia- treated polynosic and linen was higher than that for untreated, and water absorbency of liquid ammonia-traeated fabrics was all lower than that of untreated. Also, bending properties of treated fabrics were not improved compared with those of untreated ones. The rayon treated with liquid ammonia was increased not only the apparent diffusion coefficient and the rate of dyeing but also equilibrium dye adsortion, whereas polynosic and linen were increased only equilibrium dye adsortion. It is suggested that the pore sizes of liquid ammonia-treated rayon, polynosic, and linen are much smaller than that of liquid ammonia-treated cotton. |
