Easy-to-grip basketball leather

Abstract

An easy-to-grip basketball leather comprises a base fabric layer and a surface layer, wherein the outer surface of the surface layer is evenly provided with a first protrusion and a second protrusion, wherein the outer diameter of the first protrusion is greater than the outer diameter of the second protrusion, and the protrusion height of the first protrusion is not equal to the protrusion height of the second protrusion. The surface of the basketball leather of the present invention is evenly provided with protrusion particles of two outer diameters and heights. After adopting the above structure, the overall shape and shape of the protrusion particles are different from those of the existing basketball leather. Compared with the existing technology, the advantages are that the concave and convex between the two different sizes of protrusions can increase the friction coefficient and friction area, and the friction force and anti-slip property are better, which can prevent the ball from slipping when the athlete is exercising and increase the feel of the athlete when using the ball.

Technical Field

[0001] The invention relates to the technical field of ball leathers, and in particular to an easy-to-grip basketball leather. Background Art

[0002] Artificial leather is one of the commonly used materials for making basketballs. Since artificial leather itself is relatively smooth, some raised particles are artificially processed on the surface of leather basketballs to achieve the purpose of anti-slip. The existing basketball leather is particles of the same size and height evenly distributed on the leather surface. It is found that when grasping such leather, the fingers and palms cannot completely fit the leather surface. Summary of the invention

[0007] Preferably, the end faces of the first protrusion and the second protrusion are both provided with a plurality of concave holes, and the provision of the concave holes increases the friction area and improves the friction force.

[0008] Preferably, six rotationally symmetrical second protrusions are arranged around each first protrusion, one second protrusion is arranged between two first protrusions in the horizontal direction, and one row of second protrusions is arranged between two rows of first protrusions. Such an arrangement makes the first protrusions and the second protrusions more evenly distributed.

[0009] Preferably, the concave holes include a first concave hole and a plurality of second concave holes, the inner diameter of the first concave hole is larger than the inner diameter of the second concave hole, the first concave hole is located at the center of the end faces of the first protrusion and the second protrusion, and the plurality of second concave holes are arranged rotationally symmetrically about the center of the first concave hole. Such an arrangement enables the concave holes to be more evenly distributed on the end faces of the first protrusion and the second protrusion.

[0010] Preferably, the outer diameter of the first protrusion is 3.2 mm to 4 mm, and the outer diameter of the second protrusion is 2.2 mm to 3 mm. The first protrusion and the second protrusion maintain a certain outer diameter difference to increase the friction area.

[0011] Preferably, the outer diameter of the first protrusion is 3.6 mm, and the outer diameter of the second protrusion is 2.6 mm.

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Embodiment 1

[0022] like Figure 1 , Figure 2 and Figure 3As shown, an easy-to-grip basketball leather comprises a base fabric layer 1 and a surface layer 2, wherein the outer surface of the surface layer 2 is evenly provided with a first protrusion 21 and a second protrusion 22. The cross-section of the first protrusion 21 and the second protrusion 22 is circular, and the overall shape can be cylindrical or truncated cone. In this example, the shapes of the first protrusion 21 and the second protrusion 22 are both cylindrical. The outer diameter of the first protrusion 21 is greater than the outer diameter of the second protrusion 22, and the protrusion height of the first protrusion 21 is not equal to the protrusion height of the second protrusion 22.

[0023] The first protrusions 21 are arranged in a matrix on the outer surface of the surface layer 2, and the plurality of second protrusions 22 are arranged rotationally symmetrically about the center of the first protrusion 21. Figure 1 As shown, six rotationally symmetrical second protrusions 22 are arranged around each first protrusion 21, one second protrusion 22 is arranged between two first protrusions 21 in the horizontal direction, and one row of second protrusions 22 is arranged between two rows of first protrusions 21. Such an arrangement makes the first protrusions and the second protrusions more evenly distributed.

[0024] The end surfaces of the first protrusion 21 and the second protrusion 22 are both provided with a plurality of concave holes 23. The concave holes 23 include a first concave hole 231 and a plurality of second concave holes 232. The inner diameter of the first concave hole 231 is larger than the inner diameter of the second concave hole 232. The first concave hole 231 is located at the center of the end surfaces of the first protrusion 21 and the second protrusion 22, and the plurality of second concave holes 231 are rotationally symmetrically arranged around the center of the first concave hole 232. Such an arrangement allows the concave holes to be more evenly distributed on the end surfaces of the first protrusion and the second protrusion.

[0025] The outer diameter of the first protrusion 21 is 3.2 mm to 4 mm, and the outer diameter of the second protrusion 22 is 2.2 mm to 3 mm. In this example, the outer diameter of the first protrusion 21 is 3.6 mm, and the outer diameter of the second protrusion 22 is 2.6 mm. The first protrusion 21 and the second protrusion maintain a certain outer diameter difference to increase the friction area.

[0026] The height of the first protrusion 21 is greater than that of the second protrusion 22. The height of the first protrusion 21 is 1.2 mm to 2 mm, and the height of the second protrusion 22 is 0.2 mm to 1 mm. In this example, the height of the first protrusion 21 is 1.5 mm, and the height of the second protrusion 22 is 0.5 mm, and the height difference between the two is 1 mm.

[0027] The leather material of the basketball leather of the present invention is divided into a surface layer 1 and a base fabric layer 2. The surface layer 1 is a resin layer of the same material, and different shapes are pressed by a roller. The surface of the surface layer 1 is evenly provided with protrusion particles of two outer diameters and heights. The concave-convex between the two different sizes of protrusions can increase the friction coefficient and friction area, and the friction force and anti-slip performance are better.

[0028] Embodiment 2

[0029] Different from the above-mentioned embodiment 1, the protrusion height of the first protrusion 21 is less than the protrusion height of the second protrusion 22. The protrusion height of the first protrusion 21 is 0.2 mm to 1 mm, and the protrusion height of the second protrusion 22 is 1.2 mm to 2 mm. In this embodiment, the protrusion height of the first protrusion 21 is 0.5 mm, and the protrusion height of the second protrusion 22 is 1.5 mm. The outer diameter of the first protrusion 21 is 3.6 mm, and the outer diameter of the second protrusion 22 is 2.6 mm.
