Embodiment 1
[0034] Such as figure 1 As shown, a fiber-based waterproof and moisture-permeable membrane with intelligent unidirectional moisture-wicking function is composed of a hygroscopic expansion fiber layer 1, an adhesive 2 and a hydrophobic fiber layer 3, and its preparation method is as follows:
[0035] The first step: Sodium polyacrylate (relative molecular mass is 4000) is dissolved in water to prepare a sodium polyacrylate solution with a mass fraction of 20%, and N, N-methylenebisacrylamide is added as a crosslinking agent, N, N - Methylenebisacrylamide accounted for 3% of the mass fraction of sodium polyacrylate, and stirred evenly to obtain a spinning solution; prepared a hydrophilic fiber layer on a copper grid by electrospinning, the spinning voltage was 30kV, and the receiving distance was 20cm , the liquid supply rate of the spinning solution is 5mL / h, and the thickness of the obtained hydrophilic fiber layer is 15 μm;
[0036]Step 2: Spray the phenolic resin adhesive e...
Embodiment 2
[0040] Such as figure 1 As shown, a fiber-based waterproof and moisture-permeable membrane with intelligent unidirectional moisture-wicking function is composed of a hygroscopic expansion fiber layer 1, an adhesive 2 and a hydrophobic fiber layer 3, and its preparation method is as follows:
[0041] The first step: Sodium polyacrylate (relative molecular mass is 4000) is dissolved in water to prepare a sodium polyacrylate solution with a mass fraction of 5%, and N, N-methylenebisacrylamide is added as a crosslinking agent, N, N -Methylenebisacrylamide accounts for 1% of the mass fraction of sodium polyacrylate, and stirs it evenly to obtain a spinning solution; prepares a hydrophilic fiber layer on a copper grid by electrospinning, the spinning voltage is 30kV, and the receiving distance is 20cm , the liquid supply rate of the spinning solution is 5mL / h, and the thickness of the obtained hydrophilic fiber layer is 15 μm;

Embodiment 3
[0046] Such as figure 1 As shown, a fiber-based waterproof and moisture-permeable membrane with intelligent unidirectional moisture-wicking function is composed of a hygroscopic expansion fiber layer 1, an adhesive 2 and a hydrophobic fiber layer 3, and its preparation method is as follows:
[0047] The first step: dissolving sodium polyacrylate (the relative molecular mass is 4000) in water to prepare a sodium polyacrylate solution with a mass fraction of 30%, and adding N, N-methylenebisacrylamide as a crosslinking agent, N, N- Methylenebisacrylamide accounted for 5% of the mass fraction of sodium polyacrylate, and stirred evenly to obtain a spinning solution; prepared a hydrophilic fiber layer on a copper grid by electrospinning, the spinning voltage was 30kV, and the receiving distance was 20cm. The liquid supply rate of the spinning solution is 10mL / h, and the thickness of the obtained hydrophilic fiber layer is 15 μm;
[0048] The second step: Spray the phenolic resin a...
