Conventionally, a synthetic fiber filament having a cross-sectional shape with one or more constrictions is split chemically or mechanically at the constriction, and the filament is divided into a plurality of fine filaments to create a flexible wind. It is known that it is possible to obtain filaments of fine fineness and irregular cross-section that have excellent gloss and gloss (Special Publication No. 47-
No. 23969). With this method, it is difficult to completely divide the filament to make it finer, and it is not possible to obtain a sufficiently flexible texture, and the appearance and drapability are also insufficient. .

In order to improve the problems of the conventional method, the present inventors have conducted repeated studies, and found that by combining chemical splitting treatment and raising treatment, an extremely flexible texture and excellent appearance can be achieved. The present invention was achieved by discovering that a suede raised fabric having drapability can be obtained.

The polyester fiber in the present invention is preferably a polyester having ethylene terephthalate as a main repeating unit, and polyethylene terephthalate is particularly preferred.
Copolymerized polyethylene terephthalate obtained by copolymerizing methoxypolyoxyethylene glycol or the like may also be used. The degree of polymerization of polyester should be selected appropriately depending on the type of polyester, the desired fiber cross-sectional shape, etc., but in general, in the case of polyethylene terephthalate, the intrinsic viscosity measured in an O-chlorophenol solution at 35°C [ η] is 0.4 to 0.6
is appropriate.

These polyester fibers with special cross-sectional shapes are used in the form of long fibers or short fibers, and in the case of long fibers, they include processed yarns such as false twisted yarns, air jet processed yarns, spunlike processed yarns, etc., and can also be used as staple fibers. In the case of fiber, it is used as spun yarn. A fabric is made using these fibers, and the structure of the fabric is not particularly limited, and any known woven or knitted fabric may be used. Among these, in order to facilitate the raising process, it is preferable to use 3 to 9 pieces of satin weave.
Further, both long fibers and short fibers can be used as a nonwoven fabric.

In this case, examples of the alkaline substances used include sodium hydroxide, potassium hydroxide, and sodium carbonate, and if necessary, quaternary ammonium salts such as lauryldimethylbenzylammonium chloride and cetyldimethylbenzylammonium chloride are used. may be used together. These alkaline substances may also be used. The concentration of these alkaline substances to be used is not particularly limited, and is appropriately selected depending on the type and thickness of the fiber to be applied, the fabric structure heat treatment temperature, the thickness of the constriction in the cross-sectional shape, the desired degree of division, etc. . In addition, as a treatment method, (1) cold batch method, (2) pad-dry treatment method, (3) pad-moist heat treatment method, (4) immersion method, etc. are applied.

In the present invention, the conditions of the alkali treatment are set so that the entire fiber is dissolved and thinned, and at the same time, part or all of the constricted part in the cross-sectional shape of the fiber is dissolved, and the fiber is divided into smaller pieces than the original fiber. This is extremely important, and therefore it is necessary to appropriately select the alkali concentration, treatment temperature, treatment time, treatment method, etc. Not only the constriction of the cross section of the fiber is melted and split, but the entire fiber is melted and thinned, resulting in further improvement in flexibility.
