Atmospheric-pressure Plasma Device for Fabric Functional Finishing and Its Application

Atmospheric-pressure plasma equipment, comprising a carrier gas pipeline, a reactive gas pipeline, a grafting gas pipeline, a first pipeline, a second pipeline, a third pipeline, a single-electrode plasma generator cathode and a single-electrode plasma generator anode;

• wherein the third pipeline is connected with a single-electrode plasma generator consisting of the single-electrode plasma generator cathode and the single-electrode plasma generator anode;
• gas in the third pipeline is gas in the first pipeline or gas in the second pipeline;
• the gas in the first pipeline is formed by converging carrier gas in the carrier gas pipeline and reactive gas in the reactive gas pipeline;
• and the gas in the second pipeline is formed by converging the carrier gas in the carrier gas pipeline and grafting gas in the grafting gas pipeline;
• the other end of the grafting gas pipeline is connected with a grafting tank;
• heating equipment is mounted outside the grafting tank, and the grafting gas in the grafting gas pipeline is obtained by gasifying grafting monomers in the grafting tank;
• a solenoid valve and a flowmeter are mounted on each of the carrier gas pipeline, the reactive gas pipeline, the carrier gas pipeline and the grafting gas pipeline;
• the single-electrode plasma generator is connected with a power matcher through a power line;
• the single-electrode plasma generator is located in a housing with holes;
• the power matcher, a cloth guide roller and a cloth guide roller with an adjustable-speed motor are separately located outside the housing with holes;
• the cloth guide roller and the cloth guide roller with the adjustable-speed motor are arranged on two sides of the housing with holes, respectively, and are parallel to each other;
• and holes allowing a fabric and the power line to enter and exit are formed in the housing with holes;
• and a copper pipe is placed in the single-electrode plasma generator cathode;
• a small hole is formed in the copper pipe as a gas outlet of gas;
• the gas outlet is located above the single-electrode plasma generator anode;
• and the gas in the third pipeline enters the single-electrode plasma generator through the gas outlet in the single-electrode plasma generator cathode.
