  • Patent number: 5495729
    Abstract: The object of the present invention is to make the addition of a dye solution to a long cloth passing through the interior of a high temperature and high pressure steamer continuously, smoothly and surely. Suitable amount of moisture is added to a cloth prior to the supply thereof to a high temperature and high pressure steamer, and a dye solution is added to the thus soaked cloth with the use of nozzles in the interior of the high pressure steamer body. The addition of the dye solution can be made on the entire surface of the cloth speedily and effectively in the interior of the high temperature and high pressure steamer.

  • Patent number: 5370707
    Abstract: A method for bleaching a cloth comprising subjecting a cloth soaked with an aqueous bleaching solution comprising sodium chlorite to wet heat treatment at a temperature nearly to 100.degree. C., particularly subjecting a long cloth soaked with the bleaching solution to wet heat treatment continuously in an ordinary pressure wet heat treating chamber of which atmosphere being acidified to a pH of 3-4 by the use of an activation agent for making the atmosphere containing sodium chlorite acidic comprising an inorganic acid such as sulfuric acid and hydrochloric acid, an organic acid such as formic acid and acetic acid, and a carbonyl compound such as formaldehyde and acetaldehyde so as to form chlorine dioxide active for the bleaching of a cloth by the decomposition of sodium chlorite, and apparatuses for carrying out the method.

  • Patent number: 5334224
    Abstract: A method for the pretreatment of a long cloth continuously in which a cloth to be subjected to desizing, scouring and bleaching for the pretreatment thereof is preliminarily subjected to souring treatment in the sodium chlorite solution prepared by absorbing the chlorine dioxide gas, which is exhausted from the subsequent bleaching process with the use of chlorite, in a solution of H.sub.2 O.sub.2 and NaOH, and accordingly it is possible to transport the long cloth continuously in the pretreating process speedily with no need of staying the cloth in folded state for increasing the productivity and improving the quality of the product, and further to render the pretreating apparatus compact so as suitable for the production of small lot products.
