PURPOSE:To make animal hair having relatively large fiber diameters into one having relatively small fiber diameters. CONSTITUTION:Disulfide bond, hydrogen bond, hydrophobic bond, etc., in the interior of animal hair fibers usually used for common purposes are chemically cleft under a weakly alkali condition, the animal hair fibers are drawn at 50-200% draw ratio, then crosslinked and deformation is fixed to give fibers having smaller fiber diameter than animal hair fibers usually used for common purposes. |
