  • Patent number: 4507539
    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.
