Abstract

A method for low-temperature plasma treatment of a textile product such as a cloth comprising transporting a textile product to be treated through a reaction chamber, in which low-temperature plasma is produced in situ by applying high frequency electric wave to electrodes provided in the chamber uniformly without stay, for subjecting the textile product to low-temperature plasma treatment uniformly, and an apparatus therefor.

Claims

1. An apparatus for low-temperature plasma treatment of a textile product, comprising two reaction chambers arranged in series in a reduced pressure vessel, two opposing electrode plates arranged in each said chambers forming a passage of a textile product to be treated therebetween, each of said chambers having a gas nozzle for jetting a gas from outside of the reduced pressure vessel to the electrode plates, and a gas duct provided at the opposite position to the gas nozzle for exhausting the gas and evacuating the reduced pressure vessel, the combination of plates and gas nozzles operating to produce the plasma.
