A study on the Durable Press finish by Wet-Fixation Process for Rayon Fabrics (II) - Effect of Treatment Temperature and Time -

레이온 직물의 Wet-Fixation에 의한 DP가공에 관한 연구(II) -처리온도 및 시간의 영향-

The purpose of this study was to investigate the effects of treatment temperature and time on the, of easy-care and strength properties of the wet fixation processed rayon fabrics. Viscose rayon fabrics were treated with mixed resins of melamine formaldehyde (MF) and DMDHEU by one bath and two bath wet fixation processes. The MF/DMDHEU mixed resin concentrations were 50/100, 50/150, 100/100 and 100/150(g/1). Magnasium chloride was used as a catalyst. The wet fixation conditions were 24hrs at room temperature,20 mins at $75^{\circ}C$ and 5 mins at $105^{\circ}C$ Wet fixation processed fabrics did not show the difference in the resin add-one, DP ratings and wrinkle recovery angles by the different treatment temperatures and times. DP ratings were in the order of $105^{\circ}C>75^{\circ}C>room$ temp, in one bath and two bath wet fixation. Breaking and tearing strength of one bath processed fabrics showed in the order of $75^{\circ}C>room\;temp>105^{\circ}C$ The breaking strength of two bath processed fabrics showed in the order of $105^{\circ}C>75^{\circ}C>room$ temp. Tearing strength showed in the order of $75^{\circ}c>105^{\circ}C>room$ temp. Abrasion resistances were in the order of $75^{\circ}C>105^{\circ}C>room$ temp. in one bath and two bath processes.
