[0042] With the reverse side close to the skin as the reverse side, the reverse side of the stretch fabric swimming trunks is fixedly provided with a first adhesive tape 1, a second adhesive tape 2, a third adhesive tape 3, a fourth adhesive tape 4, a fifth adhesive tape 5, a sixth adhesive tape 6, a seventh adhesive tape 7, and an eighth adhesive tape 8. The width of each adhesive tape is 20 mm, and the material is nylon fiber webbing composite PU coating.

[0043] The starting point of one end of the first adhesive tape 1 is located at the quadriceps tendon, extending upward through the rectus femoris and vastus lateralis to the upper edge of the gluteus maximus, and forming an intersection with the seventh adhesive tape 7. The intersection point is located at 1 / 4 of the distance from the outer side of the waistband to the middle symmetry line of the waistband on the back of the seventh adhesive tape 7. The second adhesive tape 2 is symmetrical with the first adhesive tape 1 along the center line of the front piece, and has the same shape and structure. Both are distributed on both sides of the front piece of the swimming trunks fabric.

[0044] The starting point of one end of the third adhesive tape 3 is located at the semitendinosus muscle, and extends upward along the semitendinosus muscle through the gluteus maximus to form an intersection with the seventh adhesive tape 7. The intersection point is located at the back part of the seventh adhesive tape 7, 1 / 2 of the distance from the outer side of the waistband to the middle symmetry line of the waistband. The fourth adhesive tape 4 and the third adhesive tape 3 are symmetrical along the center line of the back piece, and have the same shape and structure. The two are distributed on both sides of the back piece of the swimming trunks fabric.

[0045] The fifth adhesive tape 5 is located at the thigh root position on one side of the front piece. The sixth adhesive tape 6 and the fifth adhesive tape 5 are symmetrically arranged along the center line of the front piece, with the same shape and structure, and are respectively distributed from the thigh root to the waist on both sides of the swimming trunks.

[0048] The buoyancy and drag reduction of the swimming trunks clothing were tested, and the test data were compared as follows:

[0049] Table 1 Comparison results of functional test data of swimsuit clothing samples in the present embodiment

[0050]

[0051] Test methods are based on FINA requirements:

[0052] 1. Buoyancy test basis: The test is conducted with reference to FINA REQUIREMENTS FOR SWIMWEAR APPROVAL (FRSA) effect from January 1, 2017, exhibit 2 test method and KN_SH_W_19.39CS swimsuit buoyancy test operation procedure.

[0053] 2. The drag reduction test is a research evaluation program of domestic universities. It is obtained by measuring the resistance of the sample in water after it is put on the mannequin. The resistance Fd encountered by the mannequin when swimming in the swimming pool is: Fd = Fw + Ff + Fp;

[0054] Among them, Fw is the wave-making resistance, Ff is the surface friction resistance, and Fp is the pressure difference resistance.

[0055] The drag reduction rate reflected in the data of Table 1 is the percentage reduction of the resistance of the sample of the present application at two water flow rates of 1.6m / s and 2.2m / s compared with the resistance of the standard sample. The resistance of the sample of the present application is smaller, which has certain advantages.

[0056] Finally, it should be noted that the specific embodiments described in this article are merely examples of the spirit of the present application, and are not intended to limit the implementation methods of the present application. Those skilled in the art of the present application may make other modifications or additions to the described embodiments and replace them in a similar manner. It is not necessary and impossible to provide all examples of all implementation methods here. These obvious changes or modifications derived from the essential spirit of the present application still fall within the scope of protection of the present application, and interpreting them as any additional limitation is contrary to the spirit of the present application.
