For example, a knitted fabric including a viscose rayon fiber, a cation-dyeable polyester fiber, a polyacrylic synthetic fiber, and a polyurethane-based elastic fiber is known (see, for example, Patent Document 1 and Patent Document 2).
-
In addition, an attempt to improve the heat retaining property by including dead air in the knitted fabric through forming an interlock structure and adopting a specific loop balance in order to improve the heat retaining property is also known (see, for example, Patent Document 3).

SUMMARY OF THE INVENTION
PROBLEMS TO BE SOLVED BY THE INVENTION
-
In consideration of heat retaining property in clothing, it is preferable to apply a method using a spun yarn and a long fiber as described in Patent Documents 1 and 2, or to provide bulkiness by an interlock structure or the like as described in Patent Document 3.
-
On the other hand, for example, in undergarments and the like, a thin, soft, and smooth knitted fabric is preferred. However, according to findings by the present inventors, a thin and soft single knit structure has an uneven skin surface, and thus has a problem of touch feeling. Furthermore, for example, when a spun yarn and a long fiber are used for the wash and wear property in addition to improving the heat retaining property as described in Patent Document 1 and Patent Document 2, the spun yarn is thick and the long fiber is thin, and thus, the unevenness of a single knit fabric becomes more remarkable.
-
In addition, the technique of Patent Document 3 is excellent in heat retaining property and does not cause a problem of surface smoothness, but causes a problem of thickness and flexibility.
-
Therefore, an object of the present invention is to provide a knitted fabric that is thin and soft and is also excellent in skin surface smoothness, heat retaining property, and wash and wear property, and a clothing including the knitted fabric.

BRIEF DESCRIPTION OF THE DRAWINGS
-
Fig. 1 is a schematic view of a knitted fabric illustrating one embodiment of the present invention.
EMBODIMENTS OF THE INVENTION
-
An embodiment of a knitted fabric of the present invention will be described in detail. The knitted fabric of the present invention includes a course of a fiber 1 made of a spun yarn and a course of a fiber 2 made of a long fiber. A heat retaining property can be improved by the spun yarn. In addition, the long fiber is excellent in wash and wear property, and in the present invention, the strength and wrinkle resistance of a single knit fabric can be improved. Fibers other than spun yarn may be included in the fiber 1, and fibers other than long fibers may be included in the fiber 2, insofar as they do not hinder the effects of the present invention.
-
In the present invention, the spun yarn is not particularly limited, and one or a plurality of types of natural fibers such as cotton, hemp, and wool, chemical fibers such as rayon and acetate, and synthetic fibers such as polyester, acrylic, and nylon may be used. In the present invention, it is preferable that the spun yarn contains cellulose fiber such as cotton, rayon, and acetate and acrylic fiber from the viewpoint of heat retaining property.
-
The cellulose fiber is not particularly limited, but is preferably a viscose rayon fiber. The viscose rayon fiber is a regenerated fiber which is spun by a viscose method and is a short fiber such as a viscose rayon fiber or a saponified acetate fiber. It is preferable that the mass fraction of the cellulose fiber to the spun yarn is 15 mass% or more. When the cellulose fiber is contained in the above range, a knitted fabric having excellent durability and moisture-induced exothermicity can be obtained. Since the knitted fabric has moisture-induced exothermicity, etc., the knitted fabric generates heat by water vapor emitted from a human body when worn, and the temperature of a garment can be increased. The mass fraction of the cellulose fiber to the spun yarn is preferably 60 mass% or less, and more preferably 40 mass% or less. By setting the upper limit of the cellulose fiber within the above range, wrinkles can be further suppressed after washing.
-
The acrylic fiber is not particularly limited, and may be a regular type polyacrylic fiber made of polyacrylonitrile, an acrylic fiber obtained by copolymerizing or adding another compound based on an acrylic composition, or a polyacrylic fiber modified to an anti-pilling type, a water-absorbing type, etc. The mass fraction of the acrylic fiber to the spun yarn is preferably 40 mass% or more, and more preferably 60 mass% or more. When the acrylic fiber is contained in the above range, an effect of further improving the heat retaining property is exhibited. The mass fraction of the acrylic fiber to the spun yarn is preferably 80 mass% or less, and more preferably 70 mass% or less. By setting the upper limit of the content ratio of the acrylic fiber within the above range, the content ratio of, for example, the cellulose fiber can be relatively improved, and the moisture-induced exothermicity can be improved.
-
It is preferable that the single fiber fineness of the acrylic fiber is 0.6 decitex or more from the viewpoint of softer texture, improvement in heat retaining property, improvement in spinning property, strength, etc. From the viewpoint of texture, the single fiber fineness of the acrylic fiber is preferably 2.2 decitex or less, and more preferably 1.5 decitex or less.
-
Considering that the knitted fabric of the present invention can be used preferably for undergarments, T-shirts, and the like that directly contact human skin, the total fineness of the fiber 1 is preferably 150 decitex or less, and more preferably 130 decitex or less from the viewpoint of excellent touch feeling and flexibility. In addition, from the viewpoint of excellent heat retaining property, the total fineness of the fiber 1 is preferably 70 decitex or more, and more preferably 90 decitex or more. It is preferable that the single fiber fineness of the spun yarn is 0.5 decitex to 2.5 decitex from the viewpoint of usage. It is preferable that the spun yarn is composed of short fiber, and the fiber length of the spun yarn is in a range of 38 mm to 52 mm.
-
In the present invention, the long fiber is not particularly limited, and for example, monofilaments and multifilaments made of chemical fiber such as rayon and acetate and synthetic fiber such as polyester, nylon, and acrylic can be appropriately used. Among them, polyester long fiber is preferable from the viewpoint of strength and wrinkle resistance. Examples of polyester long fiber include polyethylene terephthalate long fiber, polybutylene terephthalate long fiber, polytrimethylene terephthalate long fiber, and long fiber of copolymers thereof, and in addition to single component long fiber, composite long fiber having a cross section such as side-by-side and core-sheath can also be used. In the present invention, in consideration of dyeability with other materials, for example, a cation-dyeable polyester long fiber that can be dyed with a cationic dye, such as a polyethylene terephthalate long fiber copolymerized with 1.0 mol% to 3.0 mol% of a 5-sodium sulfoisophthalic acid component, is preferable. By using the cation-dyeable polyester long fiber, it is possible to perform dyeing at a lower temperature than that of a normal polyester fiber, and it is also possible to perform dyeing with the same dye as the acrylic fiber. In addition, since the cation-dyeable polyester long fiber can obtain excellent color developability and fastness at a temperature of 105°C to 115°C, it is possible to suppress deterioration due to heat of other fibers, particularly when a polyurethane-based elastic fiber is contained.
-
In the production of the cation-dyeable polyester long fiber, a method of producing polyester which is generally known can be used. In addition, as is generally known, cationic dyeability of a normal polyester is achieved by, for example, copolymerizing the normal polyester with 1.0 mol% to 3.0 mol% of a 5-sodium sulfoisophthalic acid component.
-
In the present invention, the fiber 2 is preferably a multifilament, and at this time, the number of filaments is preferably 24 to 192. The total fineness of the fiber 2 is preferably 135 decitex or less, more preferably 120 decitex or less, and still more preferably 100 decitex or less from the viewpoint of excellent touch feeling and flexibility considering that the knitted fabric of the present invention can be preferably used for undergarments, T-shirts, and the like that directly contact human skin. In addition, in terms of excellent strength, the total fineness of the fiber 2 is preferably 33 decitex or more, more preferably 40 decitex or more, and still more preferably 50 decitex or more.
-
The mass fraction of the fiber 2 to the knitted fabric is preferably 20 mass% or more, and more preferably 30 mass% or more. Within the above range, the occurrence of wrinkles of the fiber structure body after washing can be further suppressed. The mass fraction of the fiber 2 to the knitted fabric is preferably 60 mass% or less, and more preferably 50 mass% or less. Within the above range, the heat retaining property can be improved.
-
In the present invention, it is preferable that the fiber 1 and the fiber 2 described above exist in separate courses.
-
A preferable aspect of the knitted fabric of the present invention is to further contain elastic fiber from the viewpoint of wearing comfort. More preferably, it is an aspect including a course of an elastic fiber. The elastic fiber is contained in an amount of preferably 3 mass% or more, more preferably 5 mass% or more with respect to the knitted fabric. Within the above range, it is possible to increase an appropriate elongation and a gap between knitted fabric loops, thereby exhibiting an effect of smoothly following the movement of the body and further improving the wearing comfort. In addition, the elastic fiber is contained at a ratio of preferably 15 mass% or less and more preferably 13 mass% or less with respect to the knitted fabric. Within the above range, an effect of reducing excessive tightening at the time of wearing by the elastic fiber and improving the wearing comfort is exhibited.
-
As the elastic fiber, a polyurethane-based elastic fiber is preferable in terms of cost and stretchability. It is preferable that the polyurethane-based elastic fiber has an elastic recovery at 200% elongation of 90% or more. Within the above range, excellent durability against repeated wearing can be obtained. In addition, a knit structure and a knit density can be arbitrarily set depending on an intended use. In addition, the total fineness is preferably in a range of 15 decitex to 50 decitex, and more preferably in a range of 20 decitex to 45 decitex since the fiber is preferably used for undergarments, T-shirts, and the like which directly contact human skin. Furthermore, polyurethane-based elastic fibers are generally used in the form of long fibers (filaments), and polyurethane-based elastic fibers having a filament count of 1 to 3 are preferably used.
-
Furthermore, the knitted fabric of the present invention may further contain, in addition to the above, a polyester-based fiber other than those described above, a polyester-based fiber obtained by copolymerizing a third component with polyester, a polyamide-based fiber, a regenerated cellulose fiber, a protein fiber such as wool and silk, and the like. The fibers constituting the knitted fabric are used in a form of mixed fiber, mixed yarns, mixed weaves, interlaced knitting, and the like.
-
In the knitted fabric of the present invention, the course of the fiber 1 and the course of the fiber 2 described above are alternately and repeatedly present in the warp direction. This makes it possible to improve the heat retaining property and the strength. An aspect in which the fibers are alternately and repeatedly present is not particularly limited, and for example, as illustrated in a knitted fabric (4) of Fig. 1, an aspect in which the fiber 1 (1) and the fiber 2 (2) are alternately repeated every stage may be adopted, or the fibers may be alternately repeated in a state of being arranged in a plurality of stages including two or more stages, respectively.
-
In the present invention, a ratio (D2/D1) of a total fineness D2 of the fiber 2 to a total fineness D1 of the fiber 1 is in a range of 0.50 to 0.90. Here, D1 and D2 both use decitex as a unit. In the present invention, a cotton count used as a fineness unit of the spun yarn is converted to decitex by dividing 5910 by the cotton count. A specific measurement method is as described in examples described later.
-
The ratio (D2/D1) of the total fineness D2 to the total fineness D1 in the knitted fabric of the present invention is 0.50 or more, preferably 0.55 or more, and more preferably 0.60 or more. The ratio (D2/D1) of the total fineness D2 to the total fineness D1 in the knitted fabric of the present invention is 0.90 or less, preferably 0.85 or less, and more preferably 0.80 or less. (D2/D1) is most preferably 0.60 or more and 0.80 or less. Within the above range, even a single knit structure is excellent in smoothness, and an excellent touch feeling can be obtained.
-
In the knitted fabric of the present invention, a ratio (L2/L1) of a yarn length L2 of the fiber 2 to a yarn length L1 of the fiber 1 per 100 wales is greater than 1.00. The ratio is preferably 1.02 or more, more preferably 1.05 or more, and still more preferably 1.10 or more. It is preferable that the upper limit is 1.20 or less. (L2/L1) is most preferably 1.05 or more and 1.20 or less. By setting the ratio (L2/L1) of the yarn length L2 to the yarn length L1 within the above range, even a single knit structure is excellent in smoothness, and an excellent touch feeling can be obtained.
-
Therefore, when (D2/D1) is in a range of 0.60 or more and 0.80 or less and (L2/L1) is in a range of 1.05 or more and 1.20 or less, the smoothness is most excellent, and an excellent touch feeling can be obtained.
-
In general, it is known that the thinner the fiber is, the more excellent the softness and touch feeling are. However, in the present invention, it has been found that by setting the ratio (D2/D1) of the total fineness D2 to the total fineness D1 and the ratio (L2/L1) of the yarn length L2 to the yarn length L1 respectively in the above specific ranges, the unevenness of the skin surface arranged by the fiber 1 and the fiber 2 is eliminated, and effects of extremely excellent smoothness and touch feeling are exhibited.
-
Next, the knitted fabric of the present invention is not particularly limited as long as it is a single knit structure. With the single knit structure, thinness and flexibility can be obtained. Tissues such as jersey and inlay are preferable from the viewpoint of smoothness and touch feeling.
-
The clothing of the present invention includes the knitted fabric of the present invention described above. The knitted fabric of the present invention is contained in an amount of preferably 50 mass% or more of the clothing, more preferably 80 mass% or more of the clothing. The clothing is not particularly limited as long as the clothing is to be worn on a body in addition to, for example, undergarments, outerwear such as T-shirts, blousons, slacks, and skirts, and underwear such as tights, spats, camisoles, and pants, and is preferably used for various kinds of clothing. In particular, clothing that directly contacts the skin, for example, undergarments, underwear, T-shirts, tights, spats, camisole, and the like, is preferable in that the effects of the present invention can be further exhibited. Particularly preferred are undergarments and underwear.
