preparation example Construction

[0046] In another aspect of the present invention, the present invention provides a method for preparing the aforementioned unidirectional moisture-wicking fabric. The preparation method includes: forming a hydrophobic layer on a first surface of a textile substrate by first electrospinning. Therefore, the operation is simple, convenient and easy to realize.

[0047] It should be noted that the hydrophobic layer and the textile matrix are consistent with the previous description, and will not be repeated here.

[0048] In some embodiments of the present invention, the preparation method further includes: forming a hydrophilic layer on the second surface of the textile substrate by second electrospinning.

[0049] It should be noted that the hydrophilic layer is consistent with the previous description, and will not be repeated here. The above-mentioned first surface and second surface refer to the two opposite surfaces of the textile matrix, and specifically refer to the hydr...

Embodiment 1

[0065] The preparation method of unidirectional moisture-wicking fabric comprises the following steps:

[0066] (1) Polyester fabric imitation silk treatment

[0067] Immerse the polyester fabric in an alkaline solution with a bath ratio of 1:30, treat it at 95°C for 60 minutes, wash and dry it to obtain a simulated silk polyester fabric; the alkaline solution includes sodium hydroxide with a mass concentration of 4g / L, and the mass concentration is 4g / L. Concentration is the lauryl dimethyl benzyl ammonium bromide of 2g / L;

[0068] (2) Preparation of hydrophobic spinning solution

[0069] Polystyrene (PS) was dissolved in tetrahydrofuran (THF) / dimethylformamide (DMF) mixed solvent to prepare hydrophobic spinning solution. Wherein, PS mass concentration is 9.8wt%, SDS mass concentration is 0.2wt%, THF mass concentration is 45wt%, DMF mass concentration is 45wt%;

[0070] (3) Electrospinning

[0071] Deposition of hydrophobic spinning solution on one side of simulated silk ...

Embodiment 2

[0073] The preparation method of the unidirectional moisture-conducting fabric in this example is the same as in Example 1, except that the electrospinning time is 10 minutes, and the thickness of the hydrophobic layer is 6 μm.

Abstract

The invention provides a unidirectional moisture-conducting fabric and its preparation method and application, and relates to the field of dyeing and finishing. The unidirectional moisture-conducting fabric comprises: a textile substrate; a hydrophobic layer, the hydrophobic layer is arranged on one surface of the textile substrate, And the hydrophobic layer is formed by electrospinning; the porosity of the textile matrix is ​​58.3-63.4%, and the porosity of the hydrophobic layer is 23.6-53.4%. The unidirectional moisture-conducting fabric uses textiles as a substrate to improve the mechanical properties of the unidirectional moisture-conducting fabric. A hydrophobic layer with better hydrophobic effect is formed on the surface of the substrate by electrospinning. The operation is simple and convenient, and the controllability is strong. One-way moisture transfer effect is better.

Description

technical field [0001] The present invention relates to the technical field of dyeing and finishing, in particular to a unidirectional moisture-conducting fabric and its preparation method and application, more specifically, to a unidirectional moisture-conducting fabric and its preparation method and application as well as garments, oil-water separation devices, seawater desalination device or cell separation device. Background technique [0002] Unidirectional moisture-wicking fabric refers to a functional fabric that can transport liquids such as water, oil, and blood in a specific direction, but is difficult to transport in the opposite direction. This functional material is used in sports shoes, protective clothing, inner It has potential applications in household or automobile decoration materials. The current unidirectional moisture-wicking fabrics have defects such as poor mechanical properties, weak controllability, and slow unidirectional moisture-wicking speed. ...
