Surface Treatments of Wool by Potassium Hydroxide in Dehydrated Butanol

抄録

Descaled wool fibers were obtained by the treatment with potassium hydroxide in dehydrated butanol at 50°C for 17 h under gentle agitation. The modification of the cortex was examined by amino acid analysis and the damage tests of the cortex. The amino acid contents of the descaled wool samples were consistent with those of cortical cells reported by Bradbury and Peters. The optical anisotropy was well retained. These results suggest that the descaled wool fibers were obtained whose cortex structure was almost unmodified by the present treatment.
