Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth for wearing water and a swimsuit, and more particularly to a cloth and a swimsuit which have a moderate stretchability and a fitting property which do not restrict the motor function of the body in the water, and which have a function of being lifted from the water or from the water. The present invention relates to a swimsuit fabric suitable for suppressing physical fatigue due to cold and a swimsuit using the same.

[0002]

2. Description of the Related Art Underwater clothing, such as swimwear, is required to be easy to move underwater, and therefore, a cloth that is excellent in stretchability and fits appropriately to the body is used. On the other hand, in the water such as the sea and swimming pools, the body surroundings is covered with water that has higher thermal conductivity than air. Body is easily fatigued due to shrinkage of the body. Also, in the air immediately after rising from the water, water stays between the body and clothing, and since the clothing itself contains a large amount of water, the body heats when this water evaporates into the atmosphere. The body is easily fatigued by depriving and contracting blood vessels as in water. In recent years, the number of young and old men and women who exercise underwater in fitness clubs and swimming schools even in winter has increased, so even if the air temperature is lower than the pool water temperature or body temperature, especially during periods other than midsummer, There have been proposed various swimwear that can reduce the cooling of the body caused by the swimsuit.

For example, Japanese Utility Model Application Laid-Open No. 3-14178 proposes a method for reducing the cooling of the body by using fibers containing a substance that absorbs sunlight and generates heat. However, since the above heat-generating substances generate heat by absorbing the visible light and near infrared rays of the sun, heat is generated inside clothing that does not reach the light or indoor pools with lower illuminance than outdoors. There is a drawback that the effect of the above is difficult to obtain. Japanese Patent Application Laid-Open Nos. 9-41244 and 10-298854 disclose that the surface (skin surface) of the fabric that comes into contact with the skin has an uneven structure, and reduces the amount of water that comes into contact with the skin to reduce body cooling. A way to do that has been proposed. However, this method has the effect of reducing the cooling when it rises from the water, but in water with extremely high thermal conductivity, this water penetrates into the inside of the fabric and the skin surface of the fabric gets wet with water. For this reason, there has been a defect that cooling of the body in the water is not reduced and motor function is deteriorated.

Japanese Utility Model Laid-Open No. 4-89507 proposes using a fabric in which an elastic knitted fabric is bonded to both sides of a foamed rubber sheet for a heat retaining swimsuit. However, in this swimsuit, since the foamed rubber sheet blocks the front and back surfaces of the fabric, it is possible to reduce the cooling of the body in water, but the use of the foamed rubber sheet makes the fabric thick and rigid. Inferior in stretchability and fit, as well as in the ease of movement of the body and the detachability of the swimsuit, it is unsuitable especially for swimwear intended for underwater exercise. in this way,
The reality is that no swimsuit has yet been obtained that can suppress the fatigue of the wearer's body while maintaining the stretchability, fit, thinness, flexibility, etc. required for swimwear. .

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art and to maintain the performance required for a swimsuit such as stretchability, fit, flexibility, and aesthetics. It is an object of the present invention to provide a water-wearing fabric and a swimsuit using the same, which can reduce the cooling of the body when it is raised in or out of water, suppress the fatigue of the body, and reduce the discomfort when worn.

[0006]

Means for Solving the Problems As a result of intensive studies on the above problems, the present inventors have found that the elongation ratio, thickness, air permeability, air content, and water content of a fabric having a specific cross-knitted fabric are determined. The contact angle of the fabric, preventing the intrusion and passage of water into the inside of the fabric, reducing the permeability of the fabric, and increasing the air content of the fabric to increase the air layer of the fabric when rising from the water and water. The present inventors have found that the above object can be achieved by improving the holding ability, and have reached the present invention. That is, the invention claimed in the present application is as follows.

(1) A cloth having a knitted fabric in which synthetic fibers other than polyurethane elastic fibers and polyurethane elastic fibers are cross-knitted, and the elongation ratios of the cloth in a warp direction and a weft direction at a load of 4.9 N are each 25. ~ 100%, thickness 0.7 ~ 3m

A cloth for water use, wherein the cloth is 2000 cm ³ / m ² and the contact angle of water on the surface of the cloth is 90 to 180 °. (2) Polyester multifilament yarn on the surface layer,
The water landing gear according to (1), which is a knitted fabric having a three-layer structure in which a polyurethane elastic fiber is disposed in a middle layer and a bulky yarn of polyester fibers including a modified cross-section yarn having groove-shaped streaks is disposed in a back layer. Fabric. (3) A swimsuit using the fabric according to (1) or (2).

[0008]

[Function] In order to prevent body cooling due to water and to suppress body fatigue, it is important to prevent the body from coming into contact with water due to the penetration of highly thermally conductive water into the inner layer of the fabric. It is. In the cloth to be worn according to the present invention, the air layer serving as a heat insulating layer in the inner layer portion of the cloth is defined by the air content, and the difficulty of escape of air from the cloth in water is determined by the amount of ventilation, and the air layer of the cloth is further maintained. The ability to do so is defined by the contact angle with water, and these are within a specific range, so that in water or the like, the passage or infiltration of water from the surface side of the fabric to the skin side is shielded, and effective to the inner layer of the fabric. It is possible to improve the ability to hold the air layer, which serves as a heat insulating layer. Therefore, by wearing a swimsuit using the cloth, the body can be effectively prevented from being cooled by water, and the body fatigue can be suppressed. In addition, since the cloth for imbibing of the present invention uses a knitted fabric obtained by interweaving polyurethane elastic fibers to maintain an appropriate elongation and thickness, it has an appropriate stretch property suitable for swimwear and a good fit to the body. Aesthetics and the like are obtained.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION
A knitted fabric in which synthetic fibers other than polyurethane elastic fibers and polyurethane elastic fibers are knitted is used. The synthetic fibers are not particularly limited, and polyamide fibers, polyester fibers, polypropylene fibers, polyurethane fibers, and the like are used. Among them, polyester fibers and polypropylene fibers having a low official moisture regain are preferable from the viewpoint of effectively preventing water from entering the inside of the fabric. In addition, the polyester-based fibers referred to here are fibers made of a polyester polymer having a fiber-forming property such as polyethylene terephthalate, polybutylene terephthalate, and polytrimethylene terephthalate.

The fiber form may be either a filament or a staple, or may be in a mixed state, but from the viewpoint of obtaining the stretchability and stretchback property of the fabric, it is preferable to use a filament form yarn. From the viewpoint of aesthetics, it is preferable to use a multifilament yarn. Sufficient effects can be obtained even if the cross-sectional shape of the fiber is round, but from the viewpoint of retaining an air layer in the fabric, for example, W type, I type, H type, Y type, T type, X type
It is preferable to have an irregular cross section having concave groove-like streaks such as a mold, a U-form, an L-form, a Z-form, a ∞-form, and a π-form.

As the polyurethane elastic fiber to be knitted and knitted with the above synthetic fiber, a known one can be used. For example, polyether-based elastic fibers, polyester-based elastic fibers, polycarbonate-based elastic fibers, and the like are used, and the elongation-recovery property obtained by polymerizing a polymer diol component, an organic diisocyanate, and a chain extender obtained by copolymerizing these are used. It may be an excellent fiber. Further, since it is conceivable to use a pool which is sterilized and controlled by active chlorine, a polyurethane elastic fiber having chlorine resistance is more preferable.

[0012] By cross-knitting the polyurethane elastic fiber with the synthetic fiber, an appropriate stretch property and fit to the body can be obtained. It is preferable that the proportion of these fibers used is appropriately selected depending on the stretchability and fit required for the fabric. The fineness of the synthetic fibers and polyurethane elastic fibers is usually 0.1 to 15 dtex, and the thickness is usually 20 to 170 dtex, but is not limited thereto. In the case of multifilament yarn, the number of filaments is generally 5
１００100 filaments.

The cloth for water landing in the present invention has an elongation ratio in the warp direction and the weft direction under a load of 4.9 N of 25 to 25, respectively.
100%, preferably 50-80%, with a thickness of 0.1%.
It is 7 to 3 mm, preferably 1 to 2 mm. If the elongation percentage of the fabric is less than 25%, the ability to follow and fit the body in water is poor, and the ease of movement of the body is impaired. On the other hand, if the elongation rate exceeds 100%, the adhesion between the fabric and the body is poor, and the clothes are turned up or the body and the swimsuit are worn in a situation in which the resistance of the fabric to running water such as jumping in water becomes large. Plenty of water in between,
Discomfort is likely to occur, and movement of the body is impaired.
On the other hand, if the thickness of the cloth exceeds 3 mm, the cloth becomes rigid, the movement of the body is restricted, the feeling of fatigue received by the body increases, and the aesthetics deteriorate. On the other hand, when the thickness is less than 0.7 mm, the movement of the body is not restricted, but the air content described later for preventing the body from being cooled cannot be obtained, and the body fatigue due to the cooling increases.

Further, the cloth to be worn according to the present invention has a ventilation volume of 50 cm ³ / cm from the viewpoint of preventing the body from cooling down in the water and coming out of the water and suppressing body fatigue.
² sec or less, preferably 30 cm ³ / cm ² .sec or less, more preferably 0 cm ³ / cm ² .sec, and the air content is 500 to 20
00cm ³ / m ^2, preferably 800~1500cm ³ / m ^2, further fabric surface and the contact angle with water 90 to 180 °,
Preferably, it is required to be 120 to 180 °.

If the air flow exceeds 50 cm ³ / cm ² .sec, when the swimsuit is worn and enters the water, the air escapes from the inside of the fabric into the water, and the air escapes into the void in the inner layer of the fabric. Since water having high thermal conductivity enters, the effect of preventing the body from cooling cannot be obtained. The air content is 500
If it is less than cm ³ / m ² , the air in the inner layer of the fabric cannot exert the effect as a heat insulating layer, and if the air content exceeds 2000 cm ³ / m ² , the fabric becomes hot and the ease of movement decreases. If the contact angle with water on the surface of the fabric is less than 90 °, infiltration of water from the surface of the fabric cannot be prevented, and the air in the inner layer of the fabric is gradually replaced by water with the passage of water entry time, and the body is cooled. The effect of prevention is reduced. On the other hand, a contact angle exceeding 180 ° cannot be measured. It is preferable that the contact angle of the cloth surface with water does not change even in an environment where the cloth surface is in contact with water for a long time.

In a preferred embodiment of the present invention, a knitted fabric obtained by knitting a synthetic fiber other than the polyurethane elastic fiber and the polyurethane elastic fiber is a polyester multifilament yarn in a surface layer which is in direct contact with water, a polyurethane elastic fiber in an intermediate layer, A three-layer structure knitted fabric using a bulky yarn of a polyester fiber including a modified cross-section yarn having a grooved streak on a back surface layer directly in contact with the skin. As the polyester fiber multifilament yarn used for the surface layer, it is preferable to use a flat yarn from the viewpoint of increasing the contact angle with water. Further, from the viewpoint of maintaining the air layer, it is more preferable to use the modified cross-section yarn having the above-mentioned concave groove-shaped streaks.

Also, the air permeability of the fabric is reduced in the back layer,
From the viewpoint of increasing the air content and imparting bulkiness, it is preferable to use a filament or a staple having a concave groove-like streak, particularly a irregular cross-section having a flat cross section and a relatively deep concave groove. Further, in order to sufficiently obtain the stretch property and the stretch back property of the fabric, a filament-shaped yarn is preferable. The bulky yarn used for the back layer can be obtained by a known method. For example, a yarn obtained by subjecting a modified cross-section yarn to false twisting and imparting a crimp in the yarn length direction, an air-processed yarn combining a high expansion / contraction yarn and a low expansion / contraction yarn with a modified cross section, or a mixed fiber yarn may be used. By using such a bulky yarn, it is possible to obtain a fabric having a small air permeability and a large air content. Further, by knitting the bulky yarn with the polyurethane elastic yarn, a fabric having a larger air content and a reduced air permeability can be obtained.

The type of the knitted fabric is not particularly limited.
Any of a single circular knitted fabric, a double circular knitted fabric, a warp knitted fabric, a tricot knitted fabric, and a Russell knitted fabric may be used, but a warp knitted fabric is preferable for obtaining stretchability.
The knitted fabric is subjected to refining, presetting, dyeing, and the like by a known method to give a cloth to be worn. The knitted fabric after dyeing is used in order to increase the contact angle of the fabric surface with water. It is preferable to apply a water-repellent treatment to the surface. It is preferable to coat the surface of the knitted fabric that comes into contact with water with a thin stretchable polyurethane resin. This allows the air permeability to be 0 cm ³ / cm ² .sec while maintaining the air content of the fabric. Further, in order to increase the air content by retaining more air layers in the inner layer portion of the fabric, it is preferable to make the skin side of the knitted fabric into a pile shape or to raise the skin side during dyeing.

According to such a watering cloth of the present invention,
By preventing the invasion of water into the interior of the fabric, and by increasing the air content of the fabric by reducing the amount of ventilation, the ability to retain air inside the fabric can be improved. In addition, the body is less chilled in the water and when it rises into the water, and the physical fatigue of the body can be suppressed. In addition, since the polyurethane elastic fibers are cross-knitted to maintain an appropriate elongation and thickness, excellent stretchability, fit, flexibility, and aesthetics suitable for swimwear can be obtained.

A swimsuit was trial-produced using the water-absorbing cloth obtained in No. 6 so that the back side of the cloth was on the skin side. Table 1 shows the results.

[0035]

[Table 1]

From Table 1, it can be seen that in the swimwear using the cloth for wearing water according to the present invention, there is no problem in the change in the ease of movement due to the restriction of the ventilation rate, and the feeling of cooling in the water and after climbing out of the pool is reduced. It can be seen that the effect of suppressing fatigue is great. On the other hand, in Comparative Example 1, since the thickness of the fabric is thin, there is no problem in easiness of movement, but since the air permeability of the fabric is large and the air content is small, it is possible to prevent a feeling of cold when coming out of water or water. And the feeling of fatigue increased. In Comparative Example 2, since the polyurethane resin was applied and the ventilation amount was set to 0 cm ³ / cm ² .sec, the feeling of cooling and the feeling of fatigue were slightly improved, but were still insufficient. In Comparative Examples 3 and 4, since the contact angle of the fabric with water was small, it was not possible to prevent water from entering the interior of the fabric, and the feeling of cooling and fatigue increased. In Comparative Example 5, since the air permeability was large, it was not possible to prevent water from entering the interior of the fabric, and the feeling of cooling and fatigue increased.
In addition, the elongation rate of the fabric was low, so that the ease of movement was poor. Further, in Comparative Example 6, although the feeling of cooling in water or the like was reduced, the ease of movement and the feeling of fatigue increased because the elongation of the fabric was small.

[0037]

According to the present invention, the cloth for water landing is stretchable,
Since it is excellent in fitting property and the like, the air content is increased while the air permeability of the fabric is reduced, and the intrusion of water into the inside of the fabric is reduced, so that the air holding ability inside the fabric can be improved. Therefore, a swimsuit using this has excellent practicality characteristics such as ease of movement and ease of attachment and detachment, as well as a feeling of cooling due to infiltration of water and conduction of heat in the water, and further after rising from the water. The feeling of cold accompanying the heat of vaporization of water can be reduced, and fatigue of the body can be suppressed. Swimwear using the above fabric can be suitably used in a wide range of fields as clothing to exercise underwater, such as school swimwear, fitness swimwear, swimming swimwear, and rehabilitation swimwear.
