The invention provides a kind of preparation method of the fiber base waterproof humidity-permeant film with intelligent unidirectional moisture conducting function, it is characterised in that including：Hydrophilic polymers are dissolved in solvent orange 2 A, crosslinking agent is added, obtains spinning solution, hydrophilic fiber layer is prepared on base material is received by electrospinning process；By electrostatic spraying method by adhesive spraying on hydrophilic fiber layer, formed adhesive layer；Is dissolved in hydrophobic type polymer in solvent B, obtains spinning solution, and forms hydrophobic type fibrous layer on above-mentioned adhesive layer by electrospinning process, obtains tunica fibrosa；Described tunica fibrosa is heat-treated, makes polymer in hydrophilic fiber layer that chemical crosslink reaction formation moisture expantion fibrous layer occur, so as to obtain the fiber base waterproof humidity-permeant film with intelligent unidirectional moisture conducting function.The present invention has the intelligent one-way wet-guide of " low humidity perforate row steam, high humidity closed pore lead sweat ", it is ensured that human body in a variety of contexts dry and comfortable comfortable. |
