N-Methylmorpholine N-Oxide 수용액을 이용한 면직물의 의마(擬麻) 가공

Abstract

Cotton fabrics were immersed in aqueous solution of N-methylmorpholine N-oxide(NMMO) with various concentrations, padded by 300% of pick-up, concentrated at 90℃ for 30min under constant-length condition, washed, and dried, to examine a possibility of linen-like finishing by the solvent bonding between fibers. With increasing the concentration of NMMO, cross-sections of fibers changed to oval or polygonal shapes and not only the fibers but also the warp and weft were bonded each other, which produced linen-like effect on the fabrics in the aspects of appearance and mechanical properties such as the increase of stiffness and shear properties. The thickness, moisture regain and dyeability were increased with the concentration of NMMO.
