DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

The present invention relates to pile articles and particularly pile articles having a high grade of appearance and feeling in which the appearance of piles, that is at least one of color, length and fineness, varies according to place and a method for producing the pile articles.


BACKGROUND ART

Fibrous products having piles, such as cut piles or loop piles, have unique various appearances and feelings and are broadly used.
An object of production of these pile articles is to obtain fur-like articles. However, as well-known, natural furs have very complicated, delicate and high grade of colors and structures and the artificial production thereof has been substantially impossible. For example, a major part of natural furs consist of "guard hairs (tough hairs)" and "wools (soft hairs)" and have very precise piles wherein the guard hairs differ in the color and the filament diameter at the root portion, middle portion and top portion. Heretofore, many methods for producing fur-like articles in which the diameter of the filament is varied at the root portion, middle portion and top portion, have been proposed but in these methods, the fineness and length of the piles are either mechanically uniform and simple, or randomly uneven and irregular and these articles are far inferior to natural furs having complicated and precise structure. Almost all fur-like articles produced in the conventional methods do not have the complicated, precise and high grade of structures as in natural furs in the piles and are a low grade of imitation.


DISCLOSURE OF INVENTION

The first object of the present invention is to provide novel pile articles having complicated, precise and high grade of colors and structures and/or feels which are comparable with natural furs and a method for producing said articles.
The second object of the present invention is to provide novel pile articles having a high grade of fashionability, design, aesthetic property and feel and a method for producing said articles.
The pile articles of the present invention have an appearance wherein at least a part of the piles varies three-dimensionally in at least one of the color, length and fineness along a surface which varies the distance with respect to the substrate fabric.
The method of the present invention is characterized in that a fibrous structure having piles fixed to a support is rotated, the piles raised owing to the centrifugal force are contacted with a fiber treating liquid which is charged in a rotating cylinder and forms a cylindrical interface due to the centrifugal force by varying a distance between the treating liquid interface and a substrate fabric according to place to vary at least one of color, length and diameter of the piles.
The term "piles" to be used in the present invention means cut piles, loop piles, raised fibers and any other piles. The fibrous structures mean knitted fabrics, woven fabrics, non-woven fabrics and the like.
FIGS. 1-15 are explanatory sectional views showing the pile articles of the present invention.
High grade pile articles and a major part of animal furs consist of long guard hairs 3 having a large diameter and fine short wools 2. In the major part of furs, the guard hairs are fine and sharp at the top end portion, have a large diameter at the middle portion and have a small diameter at the root portion, and also in high grade pile articles, such requirements are desired. 1 is a skin portion in a natural fur, but in the artificial products, such a portion is referred to as a substrate fabric consisting of a woven fabric, fibers, a non-woven fabric and the like. The substrate fabric 1, in many cases, may contain a polyurethane elastomer, rubbery or non-elastic resins or may not contain such a substance.
As a method for producing pile articles, a method for flocking piles when knitting or weaving by means of a pile weaving or knitting machine etc., a method using a sliver knitting machine and the like, raising methods, tufting methods, electric flocking methods and other pile producing
