Detailed Description

The invention is further described with reference to the following drawings and detailed description.

Example one

As shown in fig. 1, 2 and 3, an easy-to-grasp basketball leather comprises a base fabric layer 1 and a surface layer 2, wherein first protrusions 21 and second protrusions 22 are uniformly arranged on the outer surface of the surface layer 2. The cross section of the first protrusion 21 and the second protrusion 22 is circular, the overall shape may be cylindrical or truncated cone, and both the first protrusion 21 and the second protrusion 22 are cylindrical in this example. The outer diameter of the first protrusion 21 is larger than that of the second protrusion 22, and the protrusion height of the first protrusion 21 is not equal to that of the second protrusion 22.

The first bulges 21 are arranged on the outer surface of the surface layer 2 in a matrix manner, and a plurality of second bulges 22 are arranged in a rotational symmetry manner by using the centers of the first bulges 21. As shown in fig. 1, six rotationally symmetric second protrusions 22 are disposed on the periphery of each first protrusion 21, one second protrusion 22 is disposed between two transverse first protrusions 21, and one row of second protrusions 22 is disposed between two rows of first protrusions 21. Such an arrangement makes the first and second projections more evenly distributed.

The end surfaces of the first protrusion 21 and the second protrusion 22 are provided with a plurality of concave holes 23. The shrinkage pool 23 includes a first shrinkage pool 231 and a plurality of second shrinkage pool 232, and the internal diameter of first shrinkage pool 231 is greater than the internal diameter of second shrinkage pool 232, and first shrinkage pool 231 is located the center of first arch 21 and the protruding 22 terminal surface of second, and a plurality of second shrinkage pool 231 sets up with the central rotational symmetry of first shrinkage pool 232. The arrangement enables the concave holes to be more uniformly distributed on the end surfaces of the first protrusions and the second protrusions.

The outer diameter of the first protrusion 21 is 3.2mm to 4mm, and the outer diameter of the second protrusion 22 is 2.2mm to 3 mm. The first protrusion 21 of this example has an outer diameter of 3.6mm and the second protrusion 22 has an outer diameter of 2.6 mm. The first protrusion 21 and the second protrusion maintain a certain difference in outer diameter, increasing the friction area.

The height of the first protrusion 21 is greater than the height of the second protrusion 22, the height of the first protrusion 21 is 1.2mm to 2mm, and the height of the second protrusion 22 is 0.2mm to 1 mm. In this example, the first protrusions 21 have a protrusion height of 1.5mm, the second protrusions 22 have a protrusion height of 0.5mm, and the difference between the heights is 1 mm.

The leather material of the basketball leather is divided into a surface layer 1 and a base cloth layer 2, wherein the surface layer 1 is a resin layer made of the same material, and different shapes are pressed through rollers. The surface of the surface layer 1 is uniformly provided with protruding particles with two outer diameters and height sizes, the friction coefficient and the friction area can be increased by the aid of the concave-convex portions between the protrusions with two different sizes, and friction force and anti-slip performance are better.
