Abstract
Abstract The present invention provides an artificial fur of a rising hair structure formed by implanting pile fibers through a base fabric, characterized in that the pile fibers are inclined generally longitudinally, as viewed from above the surface, the pile fibers in the widthwise central section of the rising hair structure extend in parallel to the longitudinal direction, the pile fibers in the opposite peripheral sections extend diagonally widthwise with respect to the longitudinal direction and the pile fibers in the outermost sections of the rising hair structure extend diagonally at angles in the range from 10 to 80 degrees with respect to the longitudinal direction of the rising hair structure. The present invention enables stable and economic mass production of such an artificial fur by means of a liquid-flow treatment machine.
