Abstract

The invention discloses a super-hydrophobic fiber having high air permeability, and belongs to the technical field of textiles. The super-hydrophobic fiber is prepared through the following steps of modifying cotton fibers with a cationic modifier to make the surfaces of the cotton fibers have ammonium positive charges, preparing pretreated hollow microcapsules from cholesterol modified glucan andpolylactic acid, and depositing nano-silica in the pretreated hollow microcapsules in subsequent treatment to prepare the microcapsules; and enabling the microcapsules and modified sodium lignin sulfonate to be made into a treating agent, and finally, forming a super-hydrophobic protective layer on the cotton fibers in an ethanol solution with the volume fraction of 90%. The super-hydrophobic fiber prepared by the technical scheme provided by the invention has excellent super-hydrophobic performance while keeping good air permeability.

Description

technical field [0001] The invention discloses a superhydrophobic fiber with high air permeability, which belongs to the technical field of textiles. Background technique [0002] Superhydrophobic materials refer to materials with a contact angle with water greater than 150°. Superhydrophobic materials have hydrophobic properties and self-cleaning capabilities of antifouling, waterproof and dustproof, and have very broad application prospects in people's daily life and industrial and agricultural production. Therefore, in recent years, the development of superhydrophobic materials preparation methods and related properties Research has become a hot spot of concern. Since the wettability of solid materials is mainly determined by the chemical composition and surface microscopic geometric structure, the preparation methods of superhydrophobic materials are mainly divided into two categories. One is to modify low surface energy substances on rough solid surfaces, such as fluor...
