技術の開示は多い。[Prior Art] Polyester fibers have excellent physical and chemical properties and are therefore widely used for clothing and industrial purposes. Particularly in the field of clothing, various fibers with irregular cross sections have been proposed and used to improve the quality of clothing. Among them, there are many disclosures of techniques related to multi-lobal cross-section fibers.

持つものである。For example, JP-A-50-59524 proposes a polyester fiber with an oval cross section and four lobes suitable for use in fur-like pile fabrics (Figure 3).
It is described that it is possible to produce pile fabrics that have a smooth non-tacky feel, a pleasant luster, lower bending stiffness than circular fibers, good elasticity in the pile, and suppressed fibrillation. However, since there are four lobes and therefore four recesses, and the depth of the recesses is shallow, ordinary dyed woven or knitted fabrics do not have sufficient color development (depth of color) or clarity. In addition, although a smooth feeling was observed, it was still insufficient. Here, the "smooth feeling" refers to a "smooth" feeling when lightly touching the fabric, but a moderate "squeak" when touched further.

い。Japanese Unexamined Patent Publication No. 57-29628 discloses that in order to obtain a polyester filament yarn with a texture similar to that of latent crimp composite yarns or knit/de-knit yarns in knitted fabrics, the cross section is elongated. A filament with an irregular cross section has been proposed in which the ratio of the diameter in the long axis direction to the diameter in the short axis direction is 1.5 or more. (Figure 4) Proposed examples of the filament include elliptical, cross-shaped flat,
There are eyebrow-shaped and slit-shaped flat filament types, but when knitted into a knitted fabric after applying 50 to 2000 twists per meter of filament yarn and heat setting, a knitted fabric with a special texture with an extremely crisp feel is produced. It is stated that it will be done. However, the several types of filaments with irregular cross-sections in the proposed examples have at most four lobes, few recesses, and the depth of the recesses is shallow. , the sharpness is insufficient and the smooth texture is not expressed.

No. 63-190083 discloses a technique for using flat threads with constrictions to obtain animal hair-like artificial fibers and artificial fur (Figs. 5 and 6). It is not an elliptical shape, but a normal flat thread, that is, the length of the short axis direction as a whole is approximately constant at any position in the long sleeve direction, and several constrictions are added to it. When this fiber is made into a woven or knitted fabric for general clothing, since it is a flat yarn, it is easy to bend in the short axis direction in the cross section of the fiber, and when it is made into a woven or knitted fabric, it does not have firmness or stiffness and is easy to stick to, but also has a smooth texture. It also has almost no texture.

好ましく、１．５〜２．１がより好ましい。FIG. 1 is a schematic diagram for explaining the cross-sectional shape of the fiber of the present invention. The imaginary cross-sectional shape connecting the outermost edges of each leaf is approximately elliptical, and the outer periphery is curved with almost no straight parts. In the cross section, a line segment in the long axis X direction is shown as A, and a line segment in the short axis Y direction is shown as B. In the present invention, the ratio A/B of the long axis length to the short axis length B is an important factor for the level of color development, and should be in the range of 1.3 to 2.5. When A/B is less than 1.3, the effect of improving color development is not observed, and when A/B exceeds 2.5, spinning properties and unwinding properties deteriorate, and when woven or knitted fabrics are made, firmness and The waist is small and it becomes sticky easily. A/B is preferably 1.4 to 2.3, more preferably 1.5 to 2.1.

Both leaves opposite the long sleeve of the leaf that is not in the central part of the leaf in the direction of the short axis, i.e. a and a' or C and a'
When the longest length between the vertices is C, the ratio C/B of C to the short axis length B (interlobular length of central part b') is 0.
It needs to be in the range of 5 to 0.8. This is B
This means that C is larger than C, which is important for giving a smooth and novel texture to woven or knitted fabrics. It is also important for giving a unique soft feel.

５〜０．９の範囲であることが必要である。Further, the C/B value is important for increasing elegant gloss, color development, and clarity. When the shortest length between the concave portions facing the long sleeve of the concave portions between the leaves in the short axis direction is D, the ratio of D to C (the length between the apexes of the leaf) is 0.
It needs to be in the range of 5 to 0.9.

、Ｄ／Ｃが小さいと凹部か大きいことを意味している。In other words, the value of D/C represents the size of the recess between the leaves in the short axis direction; a large D/C means a small recess, and a small D/C means a large recess. are doing.

９以下にする必要がある。The size of the recesses greatly affects color development, sharpness, gloss, glitter, and texture. If the D/C is large, the recesses will be shallow and a straight portion will be provided at the outer periphery of the fiber, which is disadvantageous in terms of color development, sharpness, gloss, glitter, and texture. Therefore, D/C is 0.
Must be 9 or less.

Color development, clarity, gloss, glitter
And the feel to the touch has deteriorated, which is not good. For this reason, D/C is required to be 0.5 or more. From the above point, D/C is preferably in the range of 0.6 to 0.8.

The length between all adjacent intersections between the intersections of the double line and the major axis is, when the length of the longest line segment between the intersections is 1, the length of any of the line segments is must be between 0.6 and 1.0.

If the lengths of the line segments between the intersection points are significantly different, color development, sharpness, gloss, etc. will be poor. Therefore, the smaller the variation in the length between the intersections, the better. When the longest length between the intersections is 1, the line segment between each intersection is preferably 0.7
