る。BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. The moisture-absorbing and releasing synthetic fibers referred to in the present invention are synthetic fibers having a high degree of moisture-absorbing and releasing properties. Such synthetic fibers are prepared by blending a moisture-absorbing and releasing compound with a fiber-forming polymer. A core-sheath composite fiber produced by blending a fiber having a hygroscopic property with a core component or a compound having hygroscopicity and a fiber-forming polymer with a fiber-forming polymer as a core component, and using the fiber-forming polymer as a sheath component. No. Examples of the fiber-forming polymer include polyamides such as nylon 6 and nylon 66, polyethylene terephthalate, polyesters obtained by copolymerizing the third component with polyethylene terephthalate units, and polyesters such as polybutylene terephthalate and polypropylene terephthalate. As the compound having moisture absorption / release properties,
Any material having good moisture absorption / release properties and little change in color tone may be used, but a modified polyalkylene oxide obtained by reaction with a polyalkylene oxide, a polyol and an aliphatic diisocyanate compound is preferably used. Polyalkylene oxide used as a raw material of the modified polyalkylene oxide is polyethylene oxide, polypropylene oxide and a copolymer of both, and a polyol is ethylene glycol.
Examples of glycols such as diethylene glycol and propylene glycol and aliphatic diisocyanates include alicyclic diisocyanates, and examples thereof include dicyclohexylmethane-4,4'-diisocyanate and 1,6-hexamethylene diisocyanate. When such a modified polyalkylene oxide is used as a compound having hygroscopicity, it is caused by an imide ring formed by a resonance structure between an isocyanate group and an aromatic ring as seen when an aromatic isocyanate compound is used. Yellowing is suppressed, and the fibers do not yellow even after long-term use, and a conjugate fiber having excellent weather resistance can be obtained.
In the present invention, the content of the modified polyalkylene oxide as a compound having a moisture absorbing / releasing property in the moisture absorbing / releasing synthetic fiber is preferably in the range of 0.5 to 60% by weight.
If the content of the modified polyalkylene oxide is less than 0.5% by weight, the desired moisture absorption / desorption property may not be obtained, and if the content exceeds 60% by weight, a problem may occur in the spinning properties. The core / sheath composite ratio when the core / sheath composite fiber is used differs depending on the polymer used, but is preferably in the range of 15/85 to 85/15 by weight.
If the ratio of the core component is smaller than this, it is inferior in moisture absorption / release properties,
If the amount of the core component is large, there is a possibility that a problem may occur in the spinning property. Next, the solar selective heat storage fiber referred to in the present invention is obtained by blending a fine powder of a transition metal carbide and a fiber-forming polymer belonging to periodic group IV, which is a solar selective heat storage agent, and melt-spinning. It is a composite fiber. As fine powders of carbides of transition metals belonging to the periodic group IV to be contained in the sunlight selective absorption and storage fibers, zirconium carbide, hafnium carbide,
Titanium carbide and the like can be mentioned. As for the particle diameter of such a carbide fine powder, the average particle diameter is preferably 5 μm or less,
If the average particle size exceeds 5 μm, problems such as a decrease in spinnability due to clogging of the spinning nozzle in the spinning step or yarn breakage and a breakage in the drawing step may occur, which is not preferable. In addition, the periodicity rule to be included in the solar selective absorption and storage fiber
The addition amount of the fine powder of the carbide of the transition metal belonging to Group IV is preferably in the range of 1.5 to 20% by weight. If the added amount of the carbide fine powder is less than 1.5% by weight, the selective absorption of sunlight cannot be obtained and the heat retaining effect is impaired, and if it exceeds 20% by weight, the strength and elongation are lowered, which is not preferable. Examples of the fiber-forming polymer to be contained in the sunlight selective absorption and storage fiber include polyamides such as nylon 6 and nylon 66, polyethylene terephthalate, polyesters obtained by copolymerizing the third component with polyethylene terephthalate units, polybutylene terephthalate, and polypropylene terephthalate. Polyester and the like are blended with a fine powder of carbide belonging to the group IV of the Periodic Law, placed on the core, and selected from these fiber-forming polymers are placed on the sheath to form a composite fiber. Light selective absorption heat storage fibers can be obtained. The present invention provides a core-sheath comprising a core component comprising a mixture of a polyamide and a polyalkylene oxide-modified product obtained by reacting a polyalkylene oxide, a polyol and an aliphatic diisocyanate compound, and a sheath component comprising a polyamide. The fabric is a mixture of the above-described moisture absorbing / releasing synthetic fiber typified by a conjugate fiber and the sunlight selective absorption / storage fiber. At this time, the moisture absorbing / releasing synthetic fiber and the sunlight selective absorption / heat storage fiber contained in the fabric are used. Should be 20/80 to 80/20. When the mixing weight ratio of the moisture absorbing / releasing synthetic fiber is less than 20, the moisture absorbing / releasing property decreases, and conversely, when the mixing weight ratio of the sunlight selective absorption / storage fiber is less than 20, heat retention cannot be obtained. . As a method of mixing the moisture absorbing / releasing synthetic fiber and the sunlight selective absorption / storage fiber, a method of twisting the two, a method of aligning the two or providing a yarn length difference and supplying them to the air agitator to perform fluid entanglement are used. As the warp of the woven fabric, a method of using the other as a weft, a method of performing cross-weaving and knitting by means such as warping and arrangement at the time of fabricating can be adopted. In any of the methods, the effects of heat retention and moisture absorption / release cannot be obtained unless the mixing weight ratio is the above.

ることができる。The transition metal carbide belonging to the periodic group IV used for the sunlight selective absorption and heat storage fiber constituting the fabric of the present invention converts light energy having a wavelength of 0.3 μm to 2 μm, which is a main component of sunlight, to a wavelength of 2 μm to 2 μm. Since it has the ability to convert to and radiate heat energy of 20 μm and reflect the heat energy of 10 μm, it exhibits good heat retention. However, since the exercise promotes sweating while having a warming effect, it is not sufficient in terms of comfort due to stuffiness, stickiness and the like. As in the present invention, the moisture absorbing / releasing component comprises a polyalkylene oxide, a core component composed of a mixture of a polyamide and a polyalkylene oxide modified product obtained by reaction with a polyol and an aliphatic diisocyanate compound, and a core composed of a sheath component composed of polyamide. A fabric comprising a mixture of a moisture absorbing / releasing synthetic fiber represented by a sheath composite fiber and a sunlight selective absorption / storage fiber, wherein the mixing weight ratio of the moisture absorbing / releasing synthetic fiber and the sunlight selective absorption / storage fiber is 20/8.
When it is configured to be 0 to 80/20, sunlight can be weakened, and a heat storage and heat retaining effect can be exhibited even at sunset, and due to the high moisture absorption / release properties of the moisture absorption / release synthetic fiber,
Since it exhibits a moisture absorbing and releasing function even under the influence of the heat retention effect and during exercise, it is possible to obtain a comfortable feeling without feeling stuffiness and stickiness.
