  In the swimming swimsuits of Patent Document 1 and Patent Document 2, the direction of the stripe by the water-repellent part and the non-water-repellent part, or the direction of the stripe by the continuous water-repellent part and the intermittent water-repellent part, the body length direction, that is, progress during swimming By arranging according to the direction, we have reduced the surface friction resistance of the swimsuit and improved the ability of the water that stays between the swimsuit and the athlete to drain, reducing the overall resistance of the swimsuit. As a result of further diligent research on the surface resistance of swimsuits, the present inventor has found that not only the straight direction (body length direction) of the water flow during swimming, but also the flow in the oblique direction due to twisting and vertical movement of the body. The present invention has been found to affect the surface friction resistance of the water and to reduce the resistance to water flow in an oblique direction in addition to the traveling direction. In addition to the effects of the inventions of Patent Document 1 and Patent Document 2, the swimsuit of the present invention achieves a more advanced technical problem by reducing the surface frictional resistance in the oblique direction.

  The swimsuit of the present invention has a continuous water repellent part having a water repellent part continuously formed on at least a part of the surface of a swimsuit made of stretchable fabric, and a water repellent part and a non-water repellent part intermittently. The formed intermittent water-repellent part has a water-repellent region formed in a stripe shape parallel to the body length direction, and the water-repellent part of the intermittent water-repellent part and the water-repellent part of the continuous water-repellent part are at least partially. In the swimsuit where the ratio of the area of the water-repellent part to the area of the water-repellent area is 70 to 90%, the water-repellent part is continuous in the left oblique direction and the right oblique direction with respect to the body length direction. It is a competitive swimsuit characterized by the fact that it was formed.

  In the swimsuit of the present invention, the width of the water-repellent part formed continuously in the body length direction, the left oblique direction and the right oblique direction is 1 mm or more and 50 mm or less in each direction. Moreover, it is preferable that the width | variety of the water repellent part formed continuously in the said body length direction, the left diagonal direction, and the right diagonal direction is substantially the same.

  The swimsuit according to the present invention is characterized in that the water repellent portions formed continuously in the body length direction, the left oblique direction, and the right oblique direction intersect at one point with the center lines of the water repellent portions in the respective directions. In addition, the angle formed by the center line of the water repellent part in the body length direction and the center line of the water repellent part in the left oblique direction, and the center line of the water repellent part in the body length direction and the center line of the water repellent part in the right oblique direction Are preferably 10 degrees or more and 25 degrees or less, respectively.

  In the swimsuit of the present invention, by providing the water repellent area as described above, not only the water flow in the straight direction (body length direction) but also the water flow in the oblique direction accompanying the twisting and vertical movement of the body. In addition, it is possible to obtain a sufficient effect of reducing the surface frictional resistance. In addition, using the drainage of the water repellent that repels water when wet, it contributes directly to reducing the surface frictional resistance of the swimsuit underwater, and reduces water intrusion from the fabric surface during swimming, Further, by providing the non-water-repellent portion, the water that has entered the swimsuit can be quickly discharged outside the swimsuit without staying between the swimsuit and the human body.

  An embodiment of a swimsuit according to the present invention will be described. In the swimsuit of the present invention, the water repellent part is a water repellent part, the non-water repellent part is a non-water repellent part, and the water repellent part is continuously formed. A continuous water repellent portion, a portion where the water repellent portion and the non-water repellent portion are intermittently formed is defined as an intermittent water repellent portion. A region where the continuous water-repellent portion and the discontinuous water-repellent portion are formed in a stripe shape parallel to the body length direction is defined as a water-repellent region, and the water-repellent region is included in at least a part of the swimsuit surface. By providing the intermittent water-repellent part, the water-repellent part can be relatively increased while ensuring water drainage, and the frictional resistance can be reduced.

  The continuous water-repellent part and the intermittent water-repellent part are provided on the swimsuit surface in a stripe shape extending substantially in the body length direction, preferably in the water flow direction during the competition. In other words, the direction of the stripe needs to be defined based on the direction of the water flow flowing along the human body, and from this point of view, the front body part and the rear body part are arranged in stripes substantially in the body length direction. In addition, it is more preferable to select the direction of the stripe with respect to the body length direction at a predetermined angle in consideration of the direction of water flow at the time of competition for the part corresponding to the flank or bulge of the human body. Further, it is possible to form a part of the swimsuit in the stripe shape and the other part to be a region where the entire surface is subjected to water repellent treatment. Further, the above three regions, that is, the region where the stripe extends in the body length direction, the region where the stripe extends at a desired angle with respect to the body length direction, and the region where the water repellent portion is provided on the entire surface are mixed in one swimsuit. May be. The arrangement position and the number of the three regions in the swimsuit can be arbitrarily selected according to the requirements of the swimsuit to be used, that is, the athlete's body shape, use conditions, and the like.

  In the swimsuit of the present invention, the water-repellent part of the intermittent water-repellent part is connected to at least a part of the water-repellent part of the adjacent continuous water-repellent part, and continuously in the left oblique direction and the right oblique direction with respect to the body length direction. A water repellent part is formed. As a result, the swimsuit according to the present invention has a continuous water repellent part (corresponding to the continuous water repellent part) continuous in the body length direction, and also a water repellent continuous in the left oblique direction and the right oblique direction with respect to the body length direction. Since it has a part, not only the flow of water in the straight direction (body length direction), but also the effect of reducing the surface friction resistance, for example, against the water flow in the oblique direction accompanying torsion or vertical movement of the body Can be obtained. The diagonally left direction is the direction from the upper left to the lower right with respect to the body length direction (72 in FIG. 5), and the diagonally right direction is the direction from the upper right to the lower left with respect to the body length direction (73 in FIG. 5).

  FIG. 5 is an enlarged view of the surface of the fabric used in the swimsuit according to the present invention. As shown in FIG. 5, an angle α formed by the center line L1 of the water repellent part A continuously formed in the body length direction 71 and the center line L2 of the water repellent part A continuously formed in the left oblique direction 72. The angle β formed by the center line L1 and the center line L3 of the water repellent part continuously formed in the right oblique direction 73 is preferably 10 degrees or more and 25 degrees or less. This is because it is most effective to reduce surface frictional resistance in water, and efficient water drainage can be ensured. When the angles α and β are smaller than 10 degrees, for example, the angle of the water repellent portion in the oblique direction is insufficient with respect to the oblique water flow generated when the swimmer twists the body at the time of swimming. The effect of reducing the surface frictional resistance cannot be obtained. If the angles α and β are larger than 25 degrees, the angle of the water-repellent portion in the oblique direction is excessive with respect to the water flow in the oblique direction, so that the angle of the water-repellent portion and the water flow approaches a right angle. Thus, a sufficient effect of reducing the surface friction resistance cannot be obtained.

  The center line L1 of the water repellent part continuous in the body length direction in the present invention is a center line with respect to the straight lines M1 and M2 respectively connecting the left and right side parts of the water repellent part continuously formed in the body length direction. The center line L2 of the water repellent part continuous in the left oblique direction is a center line with respect to the straight line M3 connecting the upper end part of the water repellent part continuously formed in the left oblique direction and the straight line M4 connecting the lower end part. The center line L3 of the water repellent part continuous in the diagonally right direction is a center line with respect to the straight line M5 connecting the upper end part of the continuous water repellent part in the diagonally right direction and the straight line M6 connecting the lower end part. .

  Further, it is preferable that the center lines of the water repellent portions in the three directions intersect at one point. As shown in FIG. 8B, for example, when considering only the case where the two center lines of the body length direction 71 and the left diagonal direction 72 intersect, a resistance reduction effect can be expected for the water flow in the left diagonal direction 72. The resistance reduction effect against the water flow in the right diagonal direction 73 is insufficient. As shown in FIG. 8 (a), if the center line of the water repellent part in the three directions intersects at one point, all points P where the center line intersects with respect to all directions of the vertical direction, the left diagonal direction, and the right diagonal direction. The resistance reduction effect can be obtained.

  In the water-repellent region, the continuous water-repellent part and the intermittent water-repellent part are provided in a stripe shape extending in the body length direction, and the water-repellent part is continuously formed in the body length direction, left oblique direction and right oblique direction, Using the drainage of the water repellent that repels water when wet, it contributes directly to reducing the surface frictional resistance of the swimsuit underwater, and reduces water intrusion from the fabric surface during swimming, Providing the non-water-repellent part helps to quickly drain the water that has entered the swimsuit to the outside of the swimsuit without staying between the swimsuit and the human body.

  The ratio of the area of the water repellent part to the area of the water repellent area is 70 to 90%. If the area of the water-repellent part is 90% or more, the water that has entered from the opening becomes difficult to escape to the outside of the swimsuit, and the resistance increases as the swimsuit swells or flutters. On the other hand, when the area of the water-repellent part is 70% or less, the water-repellent part is not much different from a swimsuit having a simple water-repellent part and a non-water-repellent part stripe, and the target effect is inferior. It is.

  The width of the water-repellent part formed continuously in the body length direction, the left oblique direction and the right oblique direction is preferably 1 mm or more and 50 mm or less in each direction. Although it can be arbitrarily determined within the range of 1 mm or more and 50 mm or less from the viewpoint of the resistance reduction effect of the swimsuit and the viewpoint of manufacturing technology, the most preferable range is 5 mm or more and 15 mm or less from the viewpoint of the operational effect. . Sewing work is involved in the production of swimsuits, but if the width of the water-repellent part is larger than 50 mm, continuous water-repellent parts or intermittent water-repellent parts may be sewn depending on the design, resulting in water repellency and water drainage. In other words, uneven portions are made to such an extent that they cannot be ignored. On the other hand, when the width of the continuous water-repellent part and the intermittent water-repellent part is less than 1 mm, the water-repellent part and the non-water-repellent part having a width of 1 mm or less are stably maintained when performing the water-repellent processing by the print formulation. It becomes difficult to produce, resulting in a clogged portion, which is not preferable in terms of water drainage. From the viewpoint of drainage and production efficiency, the width of the water-repellent part formed continuously in the body length direction, the left oblique direction and the right oblique direction is the same or close to each other. A ratio is preferred.

  The swimsuit of the present invention can be fitted to a human body by using a stretchable fabric. The material of the fabric used in the swimsuit according to the present invention is a synthetic fiber multifilament yarn such as polyamide, polyester, or polypropylene, or knitting of these synthetic fiber multifilament yarn and polyurethane elastic yarn. Alternatively, a knitted fabric or a woven fabric made of union can be used. In particular, swimming swimsuits often place importance on ease of movement, and as a material form, a knitted fabric obtained by knitting synthetic fiber multifilament yarn and polyurethane elastic yarn is more preferable. In addition, as the form of the knitted fabric, a single circular knitted fabric that is a circular knitted fabric, a double circular knitted fabric, a warp knitted fabric, a tricot fabric, or a raschel fabric can be used, but a stretch that affects the ease of movement. Tricot fabric is more preferable from the viewpoints of properties and fabric thinness. This is dyed and finished by a normal dyeing method to obtain a water repellent fabric which is the next processing.

  The water repellent used for the water repellent finish of the swimsuit according to the present invention may be appropriately selected from various water repellent treatment agents conventionally used such as silicone water repellents and fluorine water repellents. it can. Further, the treatment agent used in the water repellent part of the swimsuit according to the present invention is not limited to the name of the water repellent, and any treatment can be used as long as it substantially reduces the surface frictional resistance of the swimsuit in water. For example, it may have a name such as a printing agent or a sealing agent.

  As a method for adhering the water repellent to the fabric surface, generally industrialized print recipes are suitable, and the apparatus used is appropriately selected from a roller printing machine, an auto screen printing machine, a hand screen printing machine, etc. Selected.

The amount of the water repellent applied to the fabric varies depending on the basis weight of the base fabric, the thickness, the water repellent processed area, the type of the water repellent and the like, but is preferably 5 to ²⁰ g / m ² . It is important that the water-repellent part is provided on the surface of the swimsuit, so that another treatment agent is provided on the surface of the fabric in a continuous portion and an intermittent portion, and the water-repellent agent is further provided on the stripe. You may employ | adopt the method of providing.

  It is preferable that after the water repellent is attached to the fabric surface, a post-treatment such as a heat treatment for the purpose of promoting a crosslinking reaction for fixing the water repellent to the fabric is performed according to a normal water repellent process. The heat treatment for the purpose of promoting the crosslinking reaction can be performed using a normal pin tenter or the like.

  The surface of the fabric of the swimsuit according to the present invention is smoother in order to reduce the surface friction resistance, and the resistance reduction effect is greater. For this reason, it is preferable to perform the process of smoothing the surface of the fabric on the side subjected to the water repellent process before or after the water repellent process. As used herein, the term “smoothing” refers to a processing means that changes the surface more smoothly than before the processing by crushing the uneven shape caused by loops on the surface of the knitted fabric with heat or pressure. Among these, from the viewpoint of processing stability and productivity, calendar processing is preferable as a specific means for smoothing processing.

  As the processing machine, an ordinary heating roll and a paper roll, or a calendar processing machine made of a cotton roll, or a calendering process using a plate-like material can be used, and when a heating metal roll is used, it should be a mirror surface roll. preferable. In addition, when using it as a knitted fabric for swimming wear, for example, the calendering condition is about 1 to 60 t in linear pressure with respect to the width of 100 to 220 cm of the knitted fabric, and the roll temperature is about 130 to 250 ° C. preferable.

  As another smoothing process, a transfer printing machine having a heated metal roll and a leather belt can be used. These smoothing conditions may be set as appropriate depending on the type of knitted fabric, surface irregularity, texture, and the like.

  In order to verify the effect of the swimsuit of the example, the following measurements were performed. The measurement was performed on Example 2 and Comparative Product 1 and Comparative Product 2 below. 6 is an enlarged view of the surface of the fabric used for the competitive swimsuit of Comparative Product 1, and FIG. 7 is an enlarged view of the surface of the fabric used for the competitive swimsuit of Comparative Product 2. Comparative product 1 is a swimsuit in which a water-repellent part A and a non-water-repellent part B are provided in a striped shape in the body length direction on the swimsuit surface. The width W4 of the water-repellent part A is 7 mm and the width W5 of the non-water-repellent part B Is 7 mm, and the ratio of the area of the water-repellent part A to the area of the water-repellent area H is 50%. Comparative product 2 has a continuous water-repellent part R ′ having a water-repellent part A continuously formed on the swimsuit surface, and an intermittent water-repellent part D ′ having a water-repellent part A and a non-water-repellent part B formed intermittently. A swimsuit formed in a stripe shape parallel to the body length direction, which is water-repellent in a so-called scale-like shape, and the upper edge of the water-repellent part A is 45 degrees from the edge of the continuous water-repellent part. The lower edge of the water-repellent part A has an angle of 55 degrees with the edge of the continuous water-repellent part. The width W6 of the continuous water repellent part R ′ is 8 mm, the width W7 of the intermittent water repellent part D ′ is 10 mm, and the ratio of the area of the water repellent part A to the area of the water repellent area H is 75%. The comparative swimsuits 1 and 2 have the same fabric material, the same water repellent processing method and the same swimsuit shape as in Example 2, and only the shape of the water repellent part on the surface is different.

  The following experiment for measuring the resistance value was performed using the surface frictional resistance test apparatus described below. That is, as shown in FIG. 9, the fabric surface frictional resistance test apparatus is used for testing on both surfaces of a glass plate 96 (length: 3000 mm, width: 600 mm) supported by support columns 95 whose upper ends can freely move in the horizontal direction. The dough 97 is pasted and settled to a predetermined depth in the circulating water tank 98. The lower end of the metal support column 99 is fixed to the glass plate 96, and the upper end of the metal support column 99 is fixed to the ceiling. A strain gauge 94 is installed in an upper part of the metal support column 99. Therefore, the test cloth 97 of Example 2, Comparative Product 1 and Comparative Product 2 is pasted on both surfaces of the glass plate 96, and the magnitude of the resistance received from the water flow flowing on the surface is from the strain gauge 94. It is measured by a dynamic strain meter 93 as an electric signal, and is displayed and recorded on a personal computer 91 via an A / D converter 92. In this experiment, the glass plate 96 to which the test fabric 97 is attached is placed in the circulating water tank 98, and a water flow with a flow velocity of 1.8 m / s is applied to the glass plate 96, and the resistance value is calculated from the total resistance value measured at that time. calculate. The measurement was performed when the body length direction (stripe direction) of the test fabric was set to be parallel to the water flow, and when the body length direction was set to an angle of 20 degrees with respect to the water flow.

  The measurement results are shown in Table 1 above. Note that the numbers in parentheses are values obtained by converting the measurement result in the comparative product 1 when the water flow is parallel to the body length direction as 100. As can be seen from Table 1, when the water flow is parallel to the body length direction, the resistance value of the comparative product 2 and the example 2 is lower than that of the comparative product 1. This is accompanied by an increase in the surface water repellent area. Next, regarding the case where the water flow has an angle of 20 degrees with the body length direction, when the comparative product 1 is viewed, the resistance value is increased as compared with the case where the water flow is parallel to the body length direction. This is because there is no continuous water-repellent part in the oblique direction. The comparative product 2 has a lower resistance value than the comparative product 1, which is accompanied by an increase in the surface area of the water repellent portion. Since Example 2 has a water repellent portion formed continuously in an oblique direction, the resistance value is lower than that of the comparative product 1 when the water flow is parallel to the body length direction.

  In each of the above-described embodiments, only a so-called one-piece swimsuit shape for women is shown, but the swimsuit shape is not limited to this, and is at least a shape of a wearer that covers almost the entire body, at least an arm or a foot. The shape of the swimsuit, such as a shape covering a part, a bikini type, or a spats type, can be selected from any conventional swimsuit as required.
