Abstract

This invention provides a method for preparing a superhydrophobic silk / ultrafine viscose high-softness fabric, comprising the following steps: S1. Degumming the silk / ultrafine viscose fabric to obtain a degummed silk / ultrafine viscose fabric; S2. Adding hydrophobic micron-sized flake-like aerogel powder to ethyl acetate solvent and stirring to mix evenly to obtain a hydrophobic finishing solution; S3. Applying the hydrophobic finishing solution prepared in S2 to the surface of the fabric after degumming in step S1 in one direction, and then drying the fabric, repeating the application in the same direction as the first application to obtain a silk / ultrafine viscose fabric with a surface covered with flake-like powder; S4. Adding PDMS and hydrophobic nano-TiO2 nanoparticles to a spinnable tetraethyl orthosilicate solution, mixing and stirring evenly, and aging to a spinnable viscosity, using the side of the fabric surface covered with flake-like powder as the receiving surface, and performing electrospinning to obtain a superhydrophobic silk / ultrafine viscose high-softness fabric.
