ABSTRACT:
Pile articles, such as artificial furs, wherein at least a part of piles is colored in at least two kinds of colorations which vary in the length direction of the piles, said color variation being caused on level surfaces distant substantially constantly from a substrate fabric of said pile articles over a broad area of said pile articles, are produced by rotating a fibrous structure having piles fixed on a rotating body to raise the piles owing to centrifugal force caused by the rotation and contacting the raised piles with a treating liquid for fibers retained in a rotary container wherein a cylindrical interface of the treating liquid is formed due to the centrifugal force. The pile articles wherein the piles are uniformly gradationally colored in the length direction of the piles are also produced by gradually moving the above described level surface.
