Abstract

The invention discloses a method of preparing a super-hydrophobic fabric by plasma treatment of a nano particle composite coating. The method is characterized by comprising the steps of putting a polyester fabric in a washing agent for ultrasonic cleaning, taking out the polyester fabric, repeatedly cleaning the polyester fabric in deionized water for many times, taking out and drying the polyester fabric for future, preparing a nano particle composite solution, performing ultrasonic oscillating till complete dispersion, soaking the polyester fabric, taking out and drying the polyester fabricfor future, and performing plasma discharge treatment on the polyester fabric to form the super-hydrophobic fabric. The prepared super-hydrophobic material is nontoxic, simple in operation technology,easy to industrialize and environmentally friendly and has highdurability.

Description

technical field [0001] The invention belongs to the textile field, and in particular relates to a surface plasma finishing method. Background technique [0002] In production and life, polyester fabrics have been widely used in clothing, industry and other fields due to their high strength, good elasticity, good shape retention, and good dimensional stability. According to statistics, polyester is currently the most widely used synthetic fiber, and more and more attention has been paid to the functional modification of polyester, such as superhydrophobic, superhydrophilic modification, anti-ultraviolet, antibacterial modification and so on. Among them, superhydrophobic polyester fabrics have broad application prospects in the fields of waterproofing, moisture collection, and acid and alkali corrosion resistance. Therefore, the research on superhydrophobic modification of polyester has become a hot spot in current research. Through years of hard work, researchers have discov...
