Description of the Related Art In recent years, many antibacterial products have been proposed in various fields, and textile products (clothing, interior, household goods) are no exception. For the antibacterial fibers used in conventional fiber products, the mainstream method is to knead an antibacterial agent (eg, silver zeolite, silver zirconium phosphate, etc.) into a polymer in order to obtain antibacterial performance and convert the fibers into fibers. It is. Examples of the mode of kneading the antibacterial agent into the polymer include a method of uniformly kneading the entire filament and a method of kneading the core polymer into a sheath polymer.

下するという問題がある。In order to improve the antibacterial performance of antibacterial fibers, the concentration of the antibacterial agent in the fiber may be increased. However, in the method of uniformly kneading the antibacterial agent into the entire filament, most of the antibacterial agent is inorganic. If the concentration is higher than 5%, the yarn is liable to be broken during spinning, and the cost of the antibacterial agent is increased due to the large amount of the expensive antibacterial agent, and the elongation and strength are further reduced.

示すという問題がある。In the method of kneading an antibacterial agent into a sheath polymer by using a core / sheath structure, a composite fiber having a weight ratio of the core to the sheath of about 50:50 to 80:20 is usually produced. However, at this weight ratio, the spinnability of the sheath greatly affects the spinnability, so that the concentration of the antibacterial agent in the sheath cannot be increased, and the cost and yarn quality tend to be the same as those of the above method. There is a problem of indicating.

The present invention has been found by the fact that a core-sheath structure with less unevenness at 5: 5 or more suppresses breakage at the time of spinning, and that the antibacterial agent in the sheath portion can be highly concentrated without impairing fiber properties. Reached. That is, the present invention relates to a core-sheath type composite fiber made of a thermoplastic resin, wherein the weight ratio of the core portion to the sheath portion is 95: 5 to 98: 2, and the sheath portion contains the antibacterial agent by 1 to 20% by weight. % Of an antibacterial conjugate fiber characterized in that it contains 0.1% by weight.

As the thermoplastic resin (polymer) constituting the core and the sheath, nylon, polypropylene, polyethylene, polyester and the like can be used. The core polymer and the sheath polymer may be either the same polymer or a different polymer, and the shape of the fiber cross section is not particularly limited, and may be round or irregular.

方から下方に向かって設けられている。The antimicrobial conjugate fiber of the present invention can be obtained, for example, by conjugate spinning using a conjugate fiber spinneret described in Japanese Patent Application No. 9-145085. FIG. 1 is a cross-sectional view (without cutting a capillary) of an embodiment of the spinneret for a conjugate fiber, and FIG. 2 is a partially enlarged schematic diagram illustrating a shape of a spiral groove in the spinneret of FIG. 1. FIG. The above spinneret is configured such that the core component polymer discharged from the capillary guide hole 6 of the capillary 7 and the sheath component polymer discharged from the guide hole 3 through the outer peripheral portion 11 of the capillary 7 of the discharge guide hole 5 are guided. A helical groove 8 which becomes a composite polymer in the hole 10 and is spun from the spinning hole 12 is provided on the outer peripheral portion 11 of the capillary 7 as a flow path of the sheath component polymer from above to below. .

First, the core component polymer is introduced from the capillary guide hole 6 of the capillary 7 of the upper die plate 1, and the sheath component polymer is introduced from the guide hole 3 of the upper die plate 1.

When the liquid is introduced through the introduction hole 4 of the lower base plate through the through hole, the inside of the discharge guide hole 5 passes through the outer periphery of the capillary 6 and is guided through the guide hole 10.

合繊維を得ることができる。At this time, when the sheath component polymer is discharged through the outer periphery of the capillary 6, the polymer flowing down along the spiral groove 8 and the polymer flowing vertically out of the spiral groove 8 are separated from the spiral groove 8. It is discharged into the guide hole 10 as a polymer flow having two types of flows. Since the sheath component polymer of these two flows flows along the outer peripheral portion 11 of the capillary 6, a sheath layer having a uniform thickness is formed, and the sheath component polymer causes the sheath component polymer to flow downward from the capillary discharge hole 9 at the bottom of the capillary. The discharged core component polymer is wrapped, and a composite fiber without eccentricity wrapped in a uniform sheath layer can be obtained.

Even if it is small, it is possible to obtain a conjugate fiber in which the thickness of the sheath is uniform and the core component polymer is well wrapped.
