Description

  The present invention relates to sportswear. More specifically, the present invention relates to sportswear excellent in dryness that does not feel sticky or wet due to sweat when sweating due to exercise or the like.

  In sportswear, the wearer often exercises at the time of wearing, so that the wearer often sweats from a small amount to a large amount. The generated sweat is absorbed on the skin side of the sportswear or remains between the skin and the wear, and these moistures come into contact with the skin, causing a so-called sticky feeling and a feeling of cooling after exercise, which makes it uncomfortable. . In addition, when worn, sportswear may stick to the skin with sweat and interfere with exercise. This sticky feeling, cold feeling, and difficulty in movement are unpleasant feelings that are particularly noticeable when sweating in large quantities due to long-term exercise such as marathon or soccer.

  As a method for suppressing such discomfort, it is effective to transfer moisture from sweat absorption from the skin side of the sportswear to the front side, and to leave no moisture on the skin side, and various fabrics are being studied. . For example, various fabrics have been proposed in which the single yarn fineness and cross-sectional shape of the yarn to be used are different between the knitted fabric front side and the back side.

  Patent Document 1 uses a synthetic fiber filament having an irregular cross-section and a plurality of concave grooves in the longitudinal direction on the knitted fabric surface side, and a synthetic fiber filament having no concave portion in the longitudinal direction on the knitted fabric back side. A knitted fabric has been proposed that absorbs and diffuses moisture to reduce stickiness and provides quick drying. Patent Document 2 also uses a fiber with excellent water absorption capability such as cotton on the knitted fabric surface side, and a structure that does not leave moisture on the back side of the knitted fabric by using fibers with poor water absorption capability such as polyester filaments on the back side of the knitted fabric. Therefore, a knitted fabric that suppresses the feeling of stickiness and cooling has been proposed. These can exhibit a certain effect depending on the type of yarn used, but it is insufficient to suppress the sticky feeling, and there is a limit to the effect of reducing the sticky feeling, especially when a large amount of water is contained due to long-term exercise etc. is there. In addition, the type of thread is limited, the versatility is poor, and the use of a thread having a special cross-sectional shape may require effort for stable processing and quality stabilization of the thread.

On the other hand, a knitted fabric in which the feeling of stickiness of the skin is suppressed by giving a difference in density between the front and back sides of the knitted fabric is also being studied. For example, Patent Document 3 uses hydrophilic fibers on the knitted fabric surface side and hydrophobic fibers on the knitted fabric back side, makes the density on the knitted fabric surface side larger than the density on the knitted fabric back side, and gives irregularities on the knitted fabric surface side. Therefore, a knitted fabric having a smooth feeling of the skin has been proposed, but the knitted fabric surface side with high density and unevenness is used on the skin side, and hydrophilic fibers are present on the skin side. Therefore, the water is retained on the skin side, and even if there are irregularities, the feeling of stickiness is large, and the skin dryness is insufficient for clothing use.
Accordingly, there is currently no fabric or wear that suppresses the feeling of stickiness and coldness when a large amount of sweat is generated.

  The subject of this invention is providing the sportswear which is comfortable at the time of wear, and reduces a sticky feeling and a cold feeling at the time of a lot of sweating by long-time exercise | movement etc.

As a result of intensive studies to achieve the above-mentioned problems, the present inventors have found that the surface of a fabric having a contact cooling sensation value of not more than 240 W / m ² · ° C. when 200 g / m ² moisture is applied to at least one surface layer.

FIG. 6 is a knitted fabric organization chart of the fabric used in Example 3. It is a knitted fabric organization chart of the fabric used in Example 4. 6 is a woven fabric structure diagram of the fabric used in Example 5. FIG. 5 is a knitted fabric organization chart of the fabric used in Comparative Example 2. FIG.

Hereinafter, the present invention will be described in detail.
In the sportswear of the present invention, at least a part of the fabric constituting the sportswear is a fabric having a contact cooling sensation value of not more than 240 W / m ² · ° C. at the time of applying moisture of 200 g / m ² on at least one surface. The side is used on the skin side. Preferably it is 220 W / m ² · ° C. or less, more preferably 200 W / m ² · ° C. or less. Further, the contact cooling sensation value is desirably 120 w / m ² ° C or more. If it is less than 120 w / m ² ° C, the unevenness of the fabric becomes extremely large, and the touch becomes worse.

When wearing sportswear, it is assumed that you sweat a lot. Moisture application at 200 g / m ² is generally a significant amount of sweating, such as jogging for 30 minutes or more, and it is very important in terms of wearing comfort of sportswear that it is not sticky in this state. The amount of stickiness during sweating can be evaluated by the contact cooling sensation value. In the present invention, the contact cooling sensation value is represented by the maximum value of instantaneous heat transfer (labeled as Qmax) measured using a thermolab tester manufactured by Kato Tech.

As a method for applying moisture at the time of measurement, moisture may be applied by spraying to the measurement surface side of the sample so that the weight of the sample sampled at 8 cm × 8 cm is +1.28 g. The water temperature in the spray bottle at this time is 20 ° C. When the stickiness is large, a lot of water is present on the measurement surface, so the contact cooling sensation value becomes a very large value. On the contrary, when the surface is not sticky, that is, when there is not much water on the surface, the contact cooling sensation value becomes small. This value is preferably 240 W / m ² · ° C. or less in order to prevent stickiness.

As a first method for suitably producing a fabric having a surface with a contact cooling sensation value of 240 W / m ² · ° C. or lower when water is applied at 200 g / m ^2, when the fabric is a knitted fabric, the knitted structure is tucked There is a method of making the structure using tuck knitting where the number of loops in the well direction on one side of the knitted fabric is small, such as reversible, dimple mesh and comfort, and the uneven surface side is on the skin side. It is made using. In the knitted fabric having the knitted structure, the surface on the front side has a large number of loops in the well direction, and the unevenness is small. As the degree of unevenness on the skin side, the difference between the convex part and the concave part is preferably 0.15 to 0.50 mm, more preferably 0.20 to 0.45 mm, and particularly preferably 0.25 to 0.40 mm. It is. The difference in height between the convex part and the concave part here is taken by taking a cross-sectional photograph of the knitted fabric with an electron microscope or the like, and the surface of the knitted fabric having the above knitted structure, that is, the number of loops in the well direction is large and the surface has few irregularities. Using the layer as a reference, the height to the convex part on the skin side with large irregularities is measured at five locations and averaged. Similarly, five heights from the front side to the skin side concave portion are measured and averaged. It calculates with the following formula from each average value.
Difference in height between convex part and concave part = (average value of height from the knitted fabric surface side to the convex part on the knitted fabric skin side) −
(Average value of the height from the knitted fabric surface side to the concave portion on the knitted fabric skin side)
In addition, when there is unevenness on the front side, a reference line is drawn at a position approximately at the middle height of the front side unevenness, and the heights of the skin-side convex part and the concave part from the reference line may be obtained.

  If the difference between the height of the convex part on the skin side and the concave part is less than 0.15 mm, the unevenness is too small, and therefore it is difficult to reduce the stickiness of the knitted fabric. In addition, if the difference in height between the convex portion and the concave portion exceeds 0.50 mm, the feeling of roughness becomes large, and the fabric becomes thick, which may be unpleasant because the feeling of wearing such as stuffiness may be impaired.

When the difference between the convex portion and the concave portion on the skin side is 0.15 to 0.20 mm, other preferable yarn designs described later such as increasing the density of the front side with respect to the skin side, or making the front side finer, A knitting design is preferred.
Even in the case where the fabric is a woven fabric, it is desirable to make the skin side have an uneven structure so that the difference between the convex portion and the concave portion is 0.15 to 0.50 mm in a double weave.

As a second method for suitably producing a fabric having a surface with a contact cooling sensation value of 240 W / m ² · ° C. or less when water is applied at 200 g / m ² , the density of the knitted fabric or woven fabric constituting the front surface layer May be 1.1 to 4.5 times the density of the knitted fabric or woven fabric constituting the skin-side surface layer. Preferably it is 1.2 to 4.2 times, more preferably 1.3 to 4.0 times. As a result, a capillary phenomenon occurs and moisture can be transferred from the skin side to the front side, so that moisture hardly remains on the skin surface even when sweating a lot, and the feeling of stickiness and cooling when worn can be reduced. . In order to provide a density difference between the skin side and the front side, a multilayer knitted fabric or a multilayer woven fabric is preferable.

  When the front side density is less than 1.1 times the skin side density, the capillary phenomenon hardly occurs, and the improvement effect of stickiness due to moisture transfer due to the capillary phenomenon cannot be expected. If the density on the front side exceeds 4.5 times the density on the back side, the moisture transfer due to the capillary phenomenon is large, but the skin side becomes a rough tissue, and the texture such as tingling feeling when worn is worsened. Moreover, there is a concern that the snacking property is also deteriorated.

  In the case of a knitted fabric, the density of the front and back sides of the fabric is determined by measuring the number of stitch loops per width of 2.54 cm (1 inch) with a densimeter, a linen tester or the like. Here, the number of loops is the number of stitches of the knit loop, and stitches such as tack loops and sinker loops are not included in the number of loops. The method of changing the density of the front side and the skin side of the knitted fabric is not particularly limited, but a method using a double circular knitting machine with different numbers of gauges on the dial side and the cylinder side, or making the knitted fabric skin side with a needle-free structure The method is preferred.

As a third method for suitably producing a fabric having a surface with a contact cooling sensation value of 240 W / m ² · ° C. or lower when moisture is applied at 200 g / m ^{2, the} use of yarns on the front side and the skin side may be optimized. It is valid. The single yarn fineness of the material constituting the sportswear of the present invention can be in the range generally used in clothing and the like, and among them, the single yarn fineness is preferably 0.2 to 7.0 dtex. More preferably, the single yarn fineness on the front side is preferably smaller than the single yarn fineness on the skin side. Specifically, a yarn having a single yarn fineness of 0.3 to 3.0 dtex on which the capillary phenomenon is likely to occur on the front side, and a single yarn fineness of 1.0 to 5.0 dtex on which the water is easily transferred to the front side on the skin side. It is effective to use yarn and make the single yarn fineness on the front side smaller than the single yarn fineness on the skin side. When a modified cross-section yarn having a large surface area, which will be described later, and is prone to capillary action, is used on the front side, the single yarn fineness on the front side and the skin side may be the same. The single yarn fineness is calculated by the total fineness / number of single yarns.

  The total fineness of the material constituting the sportswear of the present invention can be in the range generally used in clothing and the like, and among them, the total fineness is preferably 16 to 200 dtex. Furthermore, the material used in the sportswear of the present invention may have crimps and fluff, the front side is a low crimped yarn that is prone to capillary action, and the skin side is a high crimp that reduces the contact area with the skin. Shrinking is preferred. The low crimped yarn has a crimp elongation of 0 to 25%, and the high crimped yarn has a crimp elongation of 25 to 250%. The crimp elongation of the false twisted yarn is measured under the following conditions.

The upper end of the crimped yarn is fixed, a load of 1.77 × 10 ⁻³ cN / dt is applied to the lower end, and the length (A) after 30 seconds is measured. Next, the load of 1.77 × 10 ⁻³ cN / dt is removed, the load of 0.088 cN / dt is applied, the length (B) after 30 seconds is measured, and the crimp elongation rate is obtained by the following formula.
Crimp elongation (%) = ((B−A) / A) × 100

Although the fabric weight of the fabric used for the sportswear of this invention is not specifically limited, 50-300 g / m < ² > is preferable, More preferably, it is 80-250 g / m < ² >. Although it does not specifically limit about thickness, 0.4-2.0 mm is preferable, More preferably, it is 0.6-1.5 mm, More preferably, it is 0.7-1.2 mm. In addition, the thickness of the knitted fabric is averaged by using a thickness measuring device manufactured by Peacock and bringing a measuring part having a diameter of 3.0 cm into contact with the knitted fabric with a load of 5 g and measuring three places.

The fabric material used in the sportswear of the present invention includes synthetic fiber multifilament yarns such as polyester, polyamide, polypropylene and polyacrylonitrile, regenerated fiber multifilament yarns such as rayon, cupra and acetate, and spun yarns obtained therefrom. And processed yarns, and mixed yarns. Further examples include natural fibers such as cotton, wool, hemp and silk, and blended yarns thereof, but are not limited thereto. In particular, a polyester multifilament is preferable as the material constituting the skin side in terms of reducing stickiness.
The processed yarn may be obtained from a multifilament generally used for clothing. For example, latent crimped multifilaments such as side-by-side type, those having crimps that have been subjected to false twisting, shaping and indentation processing on multifilaments, fluid blends and twisted yarns from two or more types of multifilaments, etc. However, it is not limited to these. Among these, false twisted yarn obtained by false twisting a multifilament is preferred from the viewpoint of swelling when stretched into fabric, stretchability and uniformity of the fabric surface.
Furthermore, synthetic fiber multifilament yarns include matting agents such as titanium dioxide, stabilizers such as phosphoric acid, ultraviolet absorbers such as hydroxybenzophenone derivatives, crystallization nucleating agents such as talc, lubricants such as aerosil, and hindered phenol derivatives. Antioxidants such as flame retardants, antistatic agents, pigments, fluorescent brighteners, infrared absorbers and antifoaming agents may be contained. Furthermore, it is also preferable to use polyurethane fibers for covering and aligning to impart stretch properties.

  The single yarn cross-sectional shape of the material constituting the fabric of the present invention is arbitrary, such as a round shape, a triangle shape, an L shape, a T shape, a Y shape, a W shape, an H shape, a # shape, an eight leaf shape, and a dog bone shape. Atypical ones or those having a hollow portion in these yarns can be used, and further, a concave portion may be continuously or partially provided in the single yarn length direction. Among them, an atypical single yarn cross section such as a W cross section having a large surface area is preferable on the front side of the fabric constituting the sportswear, and a round cross section that does not retain moisture is preferable on the skin side due to the small surface area.

It is good to use. Among sportswear, it is particularly preferable to place it on the chest, back, side, etc. where sweating easily occurs.

The fabric used for the sportswear of the present invention preferably has a coefficient of friction increase rate of 100% or less when moisture is applied on the skin surface side. The friction coefficient increase rate was prepared using a 5 cm x 5 cm sample using HEIDON-10 manufactured by Shinto Kagaku Co., Ltd., first measuring the friction coefficient at the time of drying, then applying 1 ml of moisture and measuring in the same manner, The coefficient of friction increase rate at the time of moisture application is calculated by the following formula.
[(Friction coefficient at the time of moisture application−Friction coefficient at the time of drying) / Friction coefficient at the time of drying] × 100
If the coefficient of friction increase rate at the time of water | moisture content is less than 100%, it will stick with sweat at the time of wear, and it will become sportswear which is easy to move without inhibiting an exercise | movement. More preferably, the coefficient of friction increase rate at the time of moisture application is less than 80%.
