Abstract
A method for the continuous treatment of a cloth using a low-temperature plasma, wherein a cloth is dried by heating the cloth in a reduced pressure chamber, and the cloth is then transported through a low-temperature plasma atmosphere in a low-temperature plasma treating chamber without exposing the cloth to the atmosphere under ordinary pressure. An apparatus for carrying out the process is also disclosed. The cloth can further be subjected to the low-temperature plasma polymerization treatment in another reduced pressure chamber.
Claims4
A method for continuous treatment of a cloth with the use of low-temperature plasma, comprising drying a cloth to be treated by heating the cloth in a reduced pressure chamber at a pressure between 10 to 100 Torr, and directly transporting the cloth without exposing the cloth to atmospheric pressure through a low-temperature plasma atmosphere in a low-temperature plasma treating chamber at a pressure between 0.1 to 10 Torr and an electric frequency of 1 KHz to 300 MHz.
An apparatus for the continuous treatment of cloth with the use of low-temperature plasma, comprising a low-temperature plasma treating reactor divided into three chambers, the first chamber being capable of heating the cloth therein at a reduced pressure between 10 to 100 Torr and in sequence, a low-temperature plasma treating chamber and thereafter a second reduced pressure chamber capable of subjecting the cloth therein to a pressure between 10 to 100 Torr, each of the three chambers being arranged so that the cloth in passing from one chamber to the next, is not exposed to atmospheric pressure.
