Abstract

The effects of resin finish and dyeabilities of four kinds of Iyocell fabrics that were manufactured by four kinds of pulps were investigated. The dyeabilities of Iyocell fabrics were similar, but differed from cotton fabric. In early stage of 30 minutes, cotton fabric was shown higher dye exhaustion ratio than Iyocell fabrics, however after then cotton fabric did not increase dye exhaustion, Iyocell fabrics increased continuously. At last, the dye exhaustion ratio of Iyocell fabrics were about 75% and that of cotton fabric was 65%. Two kinds of experimental procedures were applied for Iyocell fabrics. One was what the fabrics were treated with resins and washed with cellulase, and then dyed with reactive dyes. The other procedure was the fabrics were dyed with reactive dyes, and then applied the resin treatments and cellulase washing. After fibrillation and washing the undyed Iyocell fabric and the Iyocell fabric that was dyed with C.I.Reactive Red 120, their weight loss ratios were 3.5% and 2.8%, respectively. Dyeing with reactive dyes caused the crosslinking between cellulose and dyes and the crosslinking decreased fibrillation. The weight loss by enzyme washing of Iyocell fabrics decreased by the glyoxal and melamine resin treatments. The reduction of weight loss can be caused by fibrillation decrease. Dyeing and resin treating can be showed the synergic effect on the reduction of fibrillation. The effect of glyoxal resin on the reduction of fibrillation was a little better than that of melamine resin.
