[Problems to be solved by the invention]
Conventionally, fabrics used for clothes, particularly sports clothes and underwear are comfortable to wear in daily life, and cotton fibers have been used to prevent stuffiness. On the other hand, polyester has been used in order to cope with stickiness when wearing sports such as sweating or raising the temperature in clothes.
[0006]
For this reason, cotton fabric is soft and comfortable to wear, but when sweating a lot, water retention, which is a characteristic of cotton, causes problems such as stickiness, while polyester fabric has reduced stickiness when sweating, but heat conduction The rate is low, the temperature inside the clothes rises, and the amount of moisture absorption is extremely low, causing problems such as unavoidable discomfort due to stuffiness when worn in daily life, which is inconvenient to wear under both conditions was there.
[0007]
[Means for Solving the Problems]
The fabric according to the present invention is suitable for use in exercise clothes and underwear, and can be worn and worn during daily life. In addition to eliminating stickiness to the skin when worn, it is possible to obtain a comfortable comfort by suppressing the temperature rise in the clothes.

That is, the dough according to claim 1 has a high thermal conductivity, a filament yarn having a moisture absorption rate of 1 to 10%, and a spun yarn having water absorption and a moisture absorption rate of 6 to 20%. It is a fabric obtained by using a composite yarn.
By using filament yarns made of single fibers, the fabric can be stretched and the stickiness to the skin can be reduced, and by using span yarns, water absorption is given to the composite, The touch can be improved.
Furthermore, the snag property and the strength of the fabric can be improved by twisting the filament yarn and the spun yarn into a composite yarn.
[0009]
The fabric according to claim 2 is characterized in that the number of twists of the filament yarn and the spun yarn is 300 to 800 (times / m).
Thus, by setting the number of twisted yarns to be relatively high, a so-called crisp feeling is given to the fabric, and the refreshing feeling can be further improved.
[0010]
The cloth according to claim 3 is characterized in that the filament yarn is made of ethylene vinyl alcohol fiber.
Since ethylene vinyl alcohol fiber has high thermal conductivity and immediately takes away the body temperature when the fabric touches the skin, it is possible to experience a cool feeling of touch (cool feeling).
[0011]
The dough according to claim 4 is characterized in that the thermal conductivity is 0.25 (J / cm ² · s) or more in terms of heat of movement at the time of contact.
Thus, when the thermal conductivity is 0.25 (J / cm ² · s) or more in terms of the amount of heat transferred during contact, it is possible to maintain a feeling of contact cooling that can be sufficiently experienced.
[0012]
The dough according to claim 5 is characterized in that the wet friction coefficient is 50 (g) or less.
Thus, by lowering the wet friction coefficient, even when the fabric sucks sweat or the like, the slipperiness with the skin is good and the sticky feeling can be further reduced.
[0013]
The fabric according to claim 6 is formed as a woven fabric.
Depending on the use of the fabric, the composite yarn can be a woven fabric, and is suitable for use in, for example, a jacket, trousers, skirt, shirt, blouse and the like.
[0014]
The fabric according to claim 7 is formed as a knitted fabric.
Depending on the use of the fabric, the composite yarn can be knitted, and is suitable for use in underwear, underwear, and the like.
[0015]
The invention according to an eighth aspect is a garment obtained using the fabric according to any one of the first to seventh aspects.
Such a garment exhibits a high feeling of cool contact and a rich sense of coolness.
