Comparing example 1, example 2, example 3 and example 4 of the present invention, the tensile strength in example 4 is obviously inferior to that in example 1, example 2 and example 3, which shows that in the technical scheme of the present invention, a three-dimensional network cross-linked structure is formed due to the interaction of hydrogen bonds between solvated nanocellulose particles. By using the polylactic acid material melt spinning with the structure, the prepared spinning fiber has excellent porous structure performance, the problem of poor mechanical property of the traditional polylactic acid material can be effectively improved, and the moisture absorption performance and the air permeability of the polylactic acid material meet the characterization. This shows that in the method for manufacturing the basketball sports wear according to the embodiment of the present invention, solvent is adopted to dissolve the electrospinning, so that in the process of electrospinning a polymer solution containing a volatile solvent, the charged jet stream emitted from the spinneret is accelerated under the action of an external constant high-voltage electric field, the polymer jet stream is stretched under the action of the electric field force, and at the same time, the highly volatile solvent is rapidly volatilized, and finally the polymer solution jet stream is solidified and deposited on the receiving plate, so that the formed fiber has a rich pore structure. Therefore, in the wearing process of the composite fabric prepared by the method, liquid sweat can pass through the pore structure on the surface of the fabric, and under the wicking action of the pore structure, the liquid sweat can be transferred from one surface of the fabric to the other surface of the fabric and is diffused into the air, so that the heat dissipation can be promoted, and the wearing comfort is improved.
