Abstract
Abstract A fur-like article having three dimensionally varied piles characterized in that at least one part of piles varies at least one of color, length and fineness along a surface, the distance of which varies with respect to a substrate fabric of said fibrous article is produced by rotating a fibrous structure having piles fixed on a supporting body to raise the piles owing to centrifugal force caused by the rotation and contacting the raised piles with a treating liquid for fibers which is retained in a rotary container and forms a cylindrical interface due to the centrifugal force, so that the distance of the interface of the treating liquid from a substrate fabric of said pile article varies according to place, to vary at least one of the color, length and fineness of the piles.
