Description

The present invention relates to a fabric for low fluid resistance wear and a method for producing the same.
The fabric made of a single fabric of the present invention has a smooth surface on the surface side of the fabric in a normal state and a concave shape such as a stripe pattern continuous along the longitudinal direction or the width direction of the fabric on the back surface side. This is a dough that forms a part.

  Thus, the fabric of the present invention is a fabric that is cut and sewn, and is mainly used as sportswear for skiing downhill competitions, etc. The fabric of the present invention is worn as clothing and exercises and competes. Accordingly, when the longitudinal direction is extended with respect to the concave portion such as the stripe pattern formed on the back side of the fabric due to the form of exercise or competition, the movement or posture of the body part, the concave shape formed on the back side of the fabric. The portion appears as a concave portion on the surface side of the fabric as it is to form a rectifying portion, and the wear is worn and exercised or played, so that the back side of the fabric can be changed depending on the movement form and the movement and posture of the body part. When a lateral extension occurs with respect to a concave portion such as a stripe pattern formed on the fabric, the concave portion formed on the back side of the fabric appears as a convex portion on the fabric surface side, and appears as a trip portion or an adjustment. Parts a method for producing the same and a low fluid resistance wear fabric forming the.

  On the surface of an object in a fluid such as air or water, there is a layer to which the fluid adheres due to the viscosity of the fluid, and this layer cannot be adhered to the end along the surface of the object. Because it always peels at a certain position from the surface of the object (peeling point position), as a result, a low pressure part (low pressure part) is generated in the shadowed part of the object downstream, and fluid flows toward this low pressure part, It is widely known that this becomes a vortex, and as a result, a turbulent flow (large turbulent vortex) with a gradually increasing vortex occurs behind. 7a and 7b schematically show the theory, where R is a turbulent vortex region opposite to the thrust, I, I, I ... are low pressure parts, P is a separation point, and , Z is a boundary layer, and is generated between the region R of the turbulent vortex and the laminar flow Q located outside thereof.

  Since this large turbulent vortex appears as a vortex in the direction opposite to the propulsion direction, an object in the fluid, for example, a human body, is pulled backward to generate a force that goes against the thrust. In recent times, for example, high-level ski downhill wear, speed skating wear, swimsuit for swimming, and bicycle wear, which are competing for 0.01 seconds, have become a very big problem.

  Therefore, in order to reduce the resistance, the technique of actively moving the separation point rearward is, for example, by providing a projection on the surface of a swimsuit for swimming, so that the position of the separation point when there is no projection is present. The technique of aiming for low resistance by moving backward from the position of 80 degrees from 110 degrees to 130 degrees (see FIGS. 8a and 8b) is the theory that a trip portion is provided on the surface of a swimsuit for swimming. An example of this technique is disclosed.

  That is, in Patent Document 1, the pressure increases in the expanded parts such as the chest, back, and buttocks with respect to the flow of water during swimming, the pressure decreases along the bulge, and the pressure increases when it exceeds the top of the bulge. However, at this time, attention is paid to the fact that the flow of water along the surface of the swimsuit peels off and a vortex that flows backward to the back of the inflated portion is generated and becomes a resistance.

  And in the swimsuit of patent documents 1, a plurality of independent projections are provided in the substrate surface of any one part or two or more parts of a chest, an abdomen, a scapula part, and a buttocks. Are formed in a staggered pattern in the body length direction, or the protrusions arranged in a staggered pattern in the body length direction are separated by a gap extending in the body length direction. It is said that the trip part constituting the projection group reduces the generation of vortices that flow backward to the rear of the inflating part, and as a result, the shape resistance is reduced and contributes to the improvement of recording. .

  Further, as an attempt to suppress and reduce the fluid resistance of an object in a fluid such as air or water, for example, as shown in FIG. 9, for example, rectifying sections S1 and S2 each having a protruding row of protruding structures are provided on the surface of a swimsuit. There is a known technique for reducing propulsion resistance by rectifying water or air that is provided and rectified by the protruding rows of the rectifying units S1 and S2.

  In Patent Document 2, there is an attempt to suppress or reduce the fluid resistance of an object in a fluid such as water or air by positively controlling and rectifying the flow of water or air using the above means. It is disclosed.

That is, in the fluid resistance decreasing garment of Patent Document 2, the surface of the swimsuit body adjacent to one or more of the collar, side and back openings of the garment such as a swimsuit sewn with various fibrous fabric materials or sheet fabric materials The ridge structure rectification area consisting of a group of minute ridges spaced apart in parallel is configured in the direction of fluid flow during wearing competition, and the rectification section consisting of dot rows is arranged in the body length direction to arrange the fluid Therefore, the technology suppresses and reduces fluid resistance, and the technology exhibits an epoch-making effect, and its evaluation is high.
Japanese Patent No. 3537933 Japanese Patent No. 2514120

  However, in the prior art disclosed in Patent Document 1, the water flow is predicted in advance on the surface of the base material such as the chest, abdomen, scapula, and buttocks in a swimsuit for swimming. In the prior art disclosed in Patent Document 2, the surface of the swimsuit body adjacent to the collar, side and back openings of the swimwear is also provided. A straightening rectification unit composed of a large number of fine protrusions arranged in parallel and spaced apart is configured by predicting in advance the direction of fluid flow during a wearing competition.

Therefore, since the movements and forms of each athlete are not necessarily the same, it is never theoretically possible to sufficiently control the turbulent vortex by moving the separation point. Moreover, in this respect, the flow of air and water is formed with a rectifying unit and actively controlled to rectify the same.
However, it can be said that it is impossible in practice to predict all states in advance and perform cutting and sewing to complete the wear.

The protrusions forming the trip part are provided between the protrusion group and the protrusion group, for example, the protrusion has a protrusion height of 0.5 to 2.5 mm, a distance between the protrusions constituting the protrusion group of 3 to 10 mm. When the gap width is 10 mm to 20 mm, the turbulent vortex is not as small as expected, and a large result cannot be obtained. However, it had a negative image in terms of design.
In addition, this negative image has not been wiped off even in the protruding row of the protruding structure forming the rectifying unit.

  Furthermore, as a reference, the rules of the International Ski Federation (FIS) currently prohibit the provision of protrusions or protrusions with different materials on the fabric surface side of the competition wear, especially for ski downhill competitions, etc. It should also be mentioned that in developing sportswear, it is necessary to respond in accordance with the rules of the International Ski Federation.

  Thus, the fabric of the present invention is a fabric that is cut and sewn and is mainly used as sportswear for skiing downhill competitions, etc. The fabric of the present invention is worn as a wear and exercises and competes. Accordingly, when the longitudinal direction is extended with respect to a concave portion such as a stripe pattern formed on the back side of the fabric due to the movement or posture of the exercise or competition, or the movement or posture of the body part, the concave shape formed on the back side of the fabric The portion appears as a concave portion on the surface side of the fabric as it is to form a rectifying portion, and the wear is worn and exercised or played, so that the back side of the fabric can be changed depending on the movement form and the movement and posture of the body part. When the lateral extension occurs with respect to the concave portion such as a stripe pattern formed on the fabric, the concave portion formed on the back side of the fabric appears as a convex portion on the fabric surface side, and the trip portion or rectification It is to allow the realization of low fluid resistance wear fabric forming the.
