Problems solved by technology

Most of these materials are inorganic nanoparticles, which have poor affinity with fibers, so the durability of the prepared superhydrophobic fabric is not good.
In addition, when performing low surface energy treatment on substrates, most methods require the use of solvents to dissolve low surface energy substances. On the one hand, this causes solvent pollution. On the other hand, low surface energy substances only bond on the fiber surface, so they are not resistant to friction. , the superhydrophobic performance is not durable

Abstract

The invention provides a preparation method of a super-hydrophobic polyester textile. The method includes: first conducting alkali treatment on a polyester fabric so as to make fiber surfaces etched by alkali and generate uneven pits, thus improving fiber surface roughness; and then putting the fabric into a dye vat, adding a low-surface energy material, conducting sealing, and performing treatment at 80-150DEG C. The polyester textile prepared by the method has a surface water-drop static contact angle greater than 150 degrees. In the invention, no solvent is employed when low-surface energy material treatment is conducted on the fabric, thus the method is environment-friendly. In addition, the method can make the low-surface energy material go deep into the fibers, so that the prepared super-hydrophobic polyester textile has long-lasting super-hydrophobicity.

Description

【Technical field】 [0001] The invention relates to a preparation method of functional textiles, in particular to a preparation method of superhydrophobic polyester textiles. 【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 preparing a super-hydr...
