conveying the leather to a printing area of a UV printer, and printing a pattern layer on the surface of the leather;
thirdly, spraying an astringent agent on the surface of the pattern layer, and drying to obtain the basketball leather with the printed pattern;
the astringent consists of hydrophilic polyurethane resin, polypropylene micro powder, silk peptide powder, gamma- (2, 3-epoxypropoxy) propyl trimethoxy silane, a light stabilizer 770, ethanol and acetone.
By adopting the technical scheme, the polypropylene micro powder is used as the anti-sticking and wear-resisting agent, and the anti-sticking and wear-resisting agent is transferred to the surface of the coating after the astringency increasing agent coating is dried to form the isolating layer, so that the anti-sticking property and the wear resistance of the leather are improved. The silk peptide powder can improve the touch of the leather surface. The gamma- (2, 3-epoxypropoxy) propyl trimethoxy silane is used as a coupling agent, and can enhance the adhesive force of the astringent. The light stabilizer 770 can slow down the aging of the astringent coating, so that the pattern is not easy to fade and crack. The basketball leather can become very smooth after being printed by the UV printer, the manufactured basketball can slip and is not easy to grasp, after the coating is formed by spraying the astringent agent, the surface of the basketball has wet and astringent touch feeling, and the hydrophilic polyurethane resin has the moisture absorbing and releasing function, so that the basketball can be easily grasped even if a large amount of sweat is generated in violent sports by athletes.

The higher the corona intensity, the higher the electric field generated at the electrodes and the more and shorter free radicals on the leather surface. However, when the corona intensity exceeds 4kV/cm, the leather surface tension is not substantially increased even if the corona is further increased because the oxygen molecule content in the air between the motor and the corona roller is constant when the film is instantaneously subjected to the corona treatment, and more oxygen molecules cannot be activated even if the voltage and current values of the motor are increased, so that more oxygen-containing functional groups are electret to the surface of the film, and the corona intensity is too small to act as a binding force enhancing action, and thus, the corona intensity is preferably 3.5kV/cm to 4 kV/cm.
More preferably, the leather is selected from any one of PVC leather, PU leather and ZK microfiber leather.
By adopting the technical scheme, the three materials are all leather materials for manufacturing the basketball and are all suitable for the spray painting process.

0.4 to 0.6 percent of polypropylene micro powder;
1.2-1.5% of silk peptide powder;
0.5 to 1 percent of gamma- (2, 3-epoxypropoxy) propyl trimethoxy silane;
light stabilizer 7700.5-1.5%;
10-20% of ethanol;
the acetone was made up to 100.
By adopting the technical scheme, the addition amount of the polypropylene micro powder is too large, the touch feeling is dry and smooth, the anti-sticking wear resistance is good, and on the contrary, the addition amount of the polypropylene micro powder is too small, the touch feeling is wet and astringent, but the anti-sticking performance is poor; the silk peptide powder has excessive use amount and good touch, but the physical property of the astringent coating is reduced, and the raw material cost is increased; the ethanol and the acetone are compounded to be used as a solvent, so that the processing adaptability of the astringency increasing agent, namely the adaptability of the printing speed, the drying temperature, the mesh number of a printing roller and the use viscosity, can be improved. Therefore, the components can obtain the astringency increasing agent with optimal performance under the proportion, the adhesive force is enhanced, and the color fading and the cracking are not easy to occur.
More preferably, the method for producing the astringency increasing agent is as follows: mixing the polypropylene micro powder and ethanol, and then uniformly dispersing to obtain a dispersion liquid; mixing silk peptide powder, hydrophilic polyurethane resin and acetone, and grinding the mixture by a sand mill until the particle size is less than or equal to 5 mu m to obtain a mixed solution; and uniformly stirring the dispersion liquid, the mixed liquid, the gamma- (2, 3-epoxypropoxy) propyl trimethoxy silane and the light stabilizer 770 to obtain the astringency increasing agent.
