A typical example is disclosed in Japanese Patent Application Laid-Open No. Sho 62-6983.
Japanese Patent Laid-Open Publication No. 2000-214, proposes the use of multifilaments composed of fibers having a flattened cross section having a degree of flatness of 1.5 to 3, whereby a capillary is effectively formed between each fiber, so that water absorption characteristics and water conduction characteristics are reduced. It is described that an excellent fabric can be obtained. Further, the examples show the use of polyester multifilaments using surface-hydrophilized W-section fibers (single yarn fineness of 3.1 denier) to produce a water-absorbent fabric. However, although the water-absorbing quick-drying property can be obtained by making the single yarn cross section W-shaped, the single yarn fineness is large, so that it is not possible to obtain excellent water resistance, and it is not possible to obtain a fabric having a soft texture. .

Japanese Unexamined Patent Publication (Kokai) No. 62-238842 discloses a 2.08 denier W-shaped cross-section filament and a 0.2-denier filament.
A water-repellent fabric using a multifilament mixed with an ultra-fine filament of 8 denier has been proposed. However, although the water resistance is improved by using a filament having a small single-filament fineness, a fabric having a soft texture cannot be obtained because a W-shaped filament having a large single-filament fineness is used. Therefore, at present, polyester multifilaments capable of simultaneously satisfying the water-absorbing quick-drying property and / or the water resistance and the soft feel when made into a fabric have not yet been obtained.

According to the present invention, when weaving is performed using multifilaments composed of single yarns having a specific W-shaped cross-section having a flatness and a single yarn fineness, most of the single yarns constituting the warp in the woven fabric structure are particularly large. The W-shaped cross-sections of each other are filled with overlapping well, as if in a "brick-stacked form"
It is woven. It is not clear why the “brick pile form” is formed by such single yarn, but probably the warp tension during weaving and the vertical motion of the loom contribute to the rearrangement of the single yarn in the multifilament. It is presumed that it is.

FIG. 1 schematically shows an example of an arrangement of single yarns when weaving is carried out using the polyester multi-filament cross section of the present invention. In the figure, each single yarn 2 of the multifilament 1 forms a “brick-stacked form” in which uneven portions formed by a W-shaped cross section are overlapped and filled. It is presumed that the formation of such a structure expresses a soft feeling at the same time as quick water absorption and / or high water resistance. In particular,
It is considered that when a force such as bending is applied to the fabric, the single yarns constituting the fabric can easily move in the same direction, and a soft feeling can be obtained. In addition, the “brick pile form” after weaving does not lose its form even after a subsequent scouring or dyeing finishing process, and is retained until the final product.

BEST MODE FOR CARRYING OUT THE INVENTION The polyester used for the multifilament of the present invention is required to have at least 90 mol% of a repeating unit of ethylene terephthalate. In the present invention, polyethylene terephthalate is particularly preferred. The single yarn used in the present invention needs to have a W-shaped cross section and a flatness of 2 to 4, preferably 2 to 3. In the present invention, the flatness refers to a value obtained by drawing a rectangle circumscribing the W-shaped cross section of a single yarn and dividing a long side L of the rectangle by a short side H.

[0012] If the flatness of the W-shaped cross-section single yarn is less than 2, in the woven fabric, the above-mentioned "brick-stacked form" in which the single yarns constituting the multifilament are regularly overlapped is not obtained. Only a water-absorbing quick-drying property and a feeling similar to that of a fabric using a round cross-section single yarn can be obtained. On the other hand, if the flatness exceeds 4, the spinning stability becomes poor at the stage of spinning. The single filament fineness of the multifilament used in the present invention is 0.5 to 1.5 denier, preferably 0.1 to 1.5 denier.
It is 7 to 1.2 denier. If the single yarn fineness is less than 0.5 denier, the "brick-stacked form" is not formed, the effect of the W-shaped cross section is not obtained, and yarn breakage occurs frequently during spinning, making stable production difficult. In addition, single yarn fineness is 1.5
If it exceeds denier, water resistance is insufficient and a soft texture cannot be obtained.

In the present invention, the opening angle of the W-shaped cross section of the single yarn facilitates the formation of the “brick-stacked form”,
From the viewpoint of obtaining a soft texture, the angle is preferably 100 to 150 degrees, more preferably 110 to 140 degrees. The opening angle indicates the opening angle of the lower concave portion of the W-shaped cross-section single yarn, that is, the angle when a leader line is drawn from both ends of the lower concave portion. This means the sharpness of the cross-sectional shape. The smaller the angle, the sharper the cross-section, and the larger the angle, the flatter the shape. In the present invention, the variation (U%) of the fineness of the W-shaped single yarn constituting the multifilament is preferably 3% or less, more preferably 2.5% or less, for the same reason as described above. is there. Further, when the fiber fluctuation value becomes large, spots of dyeing when the fabric is made are liable to occur, and the yarn of the filament is liable to break.

The polyester multi-filament cross section of the present invention can be produced by using a known melt spinning apparatus, and the spinning stability of a filament having a W-shaped cross section and a fineness of a single yarn is ensured. In order to ensure such a condition that the fineness variation rate of the filament is 3% or less, it is preferable to use a polyester having a high degree of polymerization and to employ a method of rapidly cooling just below the spinneret or a method of increasing the spinning draft. As polyester,
It is preferable to use a polymer having an intrinsic viscosity [η] of 0.6 to 1.0. Further, in the cooling method, in order to sharpen the cross-sectional shape, it is preferable to cool a position 10 to 40 mm immediately below the spinneret from the circumference or one side with a laminar cooling wind against the yarn. The spinning draft, i.e., the ratio between the take-off speed and the polymer discharge linear speed of the spinning hole, is about 500-2000.
And 5 to 1 of the spinning draft employed in normal melt spinning.
It is preferable that the spinning is performed by increasing the size to about 0 times.

In the present invention, it is more preferable to combine the rapid cooling method and the high draft method. The reason for this is that in the case of known round or triangular filaments used for clothing, the fineness fluctuation value U% usually shows a small value of 1.5% or less, but the filament having a W-shaped cross section is usually used. In general, it is difficult to reduce the fineness variation rate to 3% or less, and in addition, the fineness variation value tends to be 5% or more for a filament having a single yarn fineness of 1.5 denier or less. In particular,
The intrinsic viscosity [η] of the polyester was set to 0.65, and the yarn was rapidly cooled at a speed of 0.5 m / sec at a speed of 0.5 m / sec at a position 20 mm immediately below the spinneret by laminar cooling air. One example is a method of spinning at about 700.

The cooled multifilament may be once drawn as an undrawn yarn and then subjected to ordinary drawing, or may be continuously drawn without being wound, ie, employing a spin draw method. Is also good. The spun unstretched yarn is continuously wound without being wound about 1.5 to 2.
The multifilament of the present invention is obtained by performing the drawing five times. The polyester multi-filament cross section of the present invention may be used after being subjected to false twisting or taslan processing within a range that does not impair the object of the invention. When used for a woven or knitted fabric, it may be left untwisted or twisted as long as the object of the present invention is not impaired. When twisting is applied, it is preferable to be about 300 T / m or less. Moreover, you may mix and use with another multifilament.

The polyester multi-filament cross section of the present invention has an excellent effect when used as a high-density woven fabric. In this case, the fabric cover factor CF is set to 20.
It is preferably set to 00 to 3000. Here, the cover factor CF of the woven fabric is defined as CF when the number of the warp or weft arranged in a woven fabric per 2.54 cm in the direction orthogonal to the warp or weft is the respective yarn density.
= (Warp density x 総 total denier of warp) + (weft density x 総 total denier of weft). The effect of the multifilament of the present invention can be obtained by using only the warp of a woven fabric, but a more excellent effect can be obtained by using the multifilament for both warp and weft. The structure of the fabric is not particularly limited, but a relatively high-density structure such as taffeta, satin, and calze is preferable.
