양모 방축가공에 따른 물리적 성질 변화 = A Study on Physical Properties of Wool with Shrink-resist treatment and Felting

다국어 초록 (Multilingual Abstract)

In this study, the effect of shrink-resist treatment agent on the wool finishing, specifically anti-felting of wool product was studied. We aimed at providing preliminary data leading to the diversification of high-value added fashionable wool product. Two type of wool fabrics, dense and sheer, were employed. The fabric specimens were treated with solutions of shrink-resist treatment agent with wet pick-up rate 110%, 130%, and 150%, respectively, by using a padding mangle. The solution treated fabric specimens were then dried at room temperature first, at 90℃ for 15 minutes in a drying oven, and finally cured at 130℃ for 3 minutes. Cured wool fabric specimens were then subjected to a felting process. The physical and mechanical properties, including shrinkage rate along warp/filling direction, thickness at specified measurement pressure, drape stiffness, and air-permeability, were analyzed. After felting process, the shrinkage rates of wool fabric specimens, treated with shrink-resist treatment agent, were lower than those of control wool fabric specimens. The stiffness values of wool fabric specimens measured by using Flexometer were increased.
