Abstract

Abstract An apparatus for treating a cloth continuously with the use of low-temperature plasma comprising a reactor provided with seal mechanisms, a plurality of cloth guide rolls provided up and down in the reactor for transporting a cloth zigzag forming snaky undulations, a plurality of partition walls provided up and down alternately in the reactor for forming zigzag cloth passages to transport the cloth therebetween, a gas supply opening provided in the vicinity of the cloth outlet for jetting a gas to the zigzag cloth passages, a pair of electrode plates provided in adjacent to the gas supply opening for producing low-temperature plasma with the combined use of high frequency electric wave applied thereto and the gas jetted from the gas supply opening, and a vacuum duct provided in the vicinity of the cloth inlet of the reactor. It is preferable further to provide a plurality of electrode pairs in the reactor by putting the zigzag cloth passages therebetween. The treatment of a cloth, for instance souring and finishing, can be done eminently with the use of this apparatus.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 169 words
An apparatus for treating a cloth continuously with the use of low-temperature plasma, comprising a reactor provided with seal mechanisms which can allow continuous taking in and out of a cloth to be treated through the reactor while maintaining the interior of the reactor under a reduced pressure, a plurality of cloth guide rolls provided up and down in the reactor for transporting the cloth zigzag forming snaky undulations, a plurality of partition walls provided up and down alternately in the reactor for forming zigzag cloth passages to transport the cloth therebetween forming snaky undulations, a gas supply opening provided in the vicinity of the cloth outlet of the reactor for jetting a gas to the zigzag cloth passages, a pair of electrode plates provided adjacent to the gas supply opening for producing low-temperature plasma with combined use of high frequency electric wave applied thereto and the gas jetted from the gas supply opening, and a vacuum duct provided in the vicinity of the cloth inlet of the reactor.
Claim 2
Independent Claim 169 words
An apparatus for treating a cloth continuously with the use of low-temperature plasma, comprising a reactor provided with seal mechanisms which can allow continuous taking in and out of a cloth to be treated through the reactor while maintaining the interior of the reactor under a reduced pressure, a plurality of cloth guide rolls provided up and down in the reactor for transporting the cloth zigzag forming snaky undulations, a plurality of partition walls provided up and down alternately in the reactor for forming zigzag cloth passages to transport the cloth therebetween forming snaky undulations, a gas supply opening provided in the vicinity of the cloth outlet of the reactor for jetting a gas to the zigzag cloth passages, a pair of electrode plates provided adjacent to the gas supply opening for producing low-temperature plasma with combined use of high frequency electric wave applied thereto and the gas jetted from the gas supply opening, and a vacuum duct provided in the vicinity of the cloth inlet of the reactor.
Claim 3
Dependent Claim 36 words
