Claim 0:
1. 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.
