Problems solved by technology

Most of these materials are inorganic nanoparticles. However, due to the weak binding force between the nanoparticles and the fiber matrix, the fabrics prepared above are easily affected by mechanical forces such as finger pressing, washing and mechanical friction, resulting in fabrics in normal times. It is easy to lose superhydrophobicity during use, so the durability of superhydrophobic performance is not good

Abstract

The invention provides a super-durable and super-hydrophobic textile and its making method. The method comprises the following steps: carrying out alkaline treatment of a terylene fabric to make the surfaces of micro-sized fibers have a nanometer rough structure and make the fabric have a micro-nano structure rough surface, and carrying out low surface energy treatment of the fabric by a mixed solution comprising long-chain alkyl silane and a polydimethylsiloxane compound to obtain the super-durable and super-hydrophobic textile. The static contact angle of water drops on the surface of the terylene fabric prepared in the invention is greater than 150DEG, the water drops can easily roll on the surface of the fabric, and the textile still has an excellent super-hydrophobic performance after strong friction, long-time washing, and long-time immersion in a strong acid, a strong alkali and a strong electrolyte solution.

Description

【Technical field】 [0001] The invention relates to a preparation method of functional textiles, in particular to a super-durable super-hydrophobic textile and a preparation method thereof. 【Background technique】 [0002] Superhydrophobic textiles have special wettability, that is, the contact angle of water droplets on the surface of the fabric is greater than 150°, and it is easy to roll on its surface. The water droplets will take away the dirt on the surface during the rolling process, which is the so-called "lotus leaf self-cleaning effect". At the same time, the super-hydrophobic property enables the product to achieve "not wet after rain, retractable at any time", and also avoids the impregnation, degradation and aging of the fiber matrix by water, thereby prolonging the service life of the fabric. Superhydrophobic textiles are widely used in industrial production, medical treatment, military products and daily life. [0003] There are two key technologies for prepari...
