An apparatus for low-temperature plasma treatment of a sheet material, comprising a plurality of reaction zones through which the sheet material is transported in an enclosed reaction chamber whose inner pressure can be reduced, in which the reaction zones are provided respectively with an electrode communicating to a high frequency generating device and a plurality of jet nozzles for supplying a gas thereto for generating low-temperature plasma gas, and the reaction chamber and the reaction zones are earthed. Another apparatus for the same purpose is to provide a liquid medium passage passing through the guide rolls for transporting a sheet material to be treated and through the electrodes under reduced pressure for heating or cooling the sheet material under treatment to a prescribed temperature. Further an electric energy feeding device for the electrodes comprising a shielded wire jointer having a cooling mechanism for connecting a shielded wire coming out of a high frequency generating device to the electrodes for generating low-temperature plasma.

Apparatus for low-temperature plasma treatment of sheet material

An electrode plate for generating low temperature plasma comprising a plurality of long electrode plate members with the same form, a plurality of cooling water passages, which serve simultaneously as support members, for connecting each pair of the adjacent electrode plate members respectively along their longitudinal direction with a cooling water passage therebetween so as to arrange the adjacent electrode plate members alternately up and down in parallel with no formation of a projection, and cooling water communicating pipes provided outside the electrode plate members. By arranging a pair of the present inventive electrode plates up and down in parallel and supplying high frequency electric current thereto, low temperature plasma can be generated uniformly and effectively all over the electrode plates.

Electrode plate for generating plasma

An apparatus 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.

Apparatus for low-temperature plasma treatment of a textile product

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.

Method for continuous treatment of a cloth with the use of

An apparatus for treating a textile product with the use of low-temperature plasma includes a reactor, and an arrangement for transporting a textile product to be treated, located within the reactor and arranged to move the textile product between taking-up shafts. The textile product is passed through a passage in the reactor formed between a pair of electrode plates. A mechanism maintains a vacuum in the interior of the reactor, and gas is supplied into the reactor between the electrode plates. The electrode plates are connected to produce a low-temperature plasma therebetween. The textile product such as a cloth, string or yarn can be treated effectively using only small amounts of heat energy and water resource.
