DRAFT-TYPE PROCESSING DEVICE AND PROCESSING METHOD

摘要

An apparatus for performing dyeing, scouring, bleaching, feeling improvement and the like by transferring and circulating a cloth using an air flow and a liquid flow by means of a draft-type processing device having an annular cloth processing passage which connects at both ends thereof a transfer passage and a residence reservoir, and a processing method, in which cloth is charged to be efficiently subjected to a series of processing steps, which includes heating, keeping of predetermined temperatures, cooling and drying, in a short period of time. The residence reservoir is provided such that its outlet is disposed to be lower than its inlet and is provided in a lower position than a ground where a processing apparatus is installed. Accordingly, the cloth can be easily charged into and taken out of the outlet of the residence reservoir in the low position, and since a treatment fluid jetting section is provided at an inlet of the transfer passage (or the outlet of the residence reservoir), little tractive tension is applied to the cloth at the time of circulation to prevent generation of rope creases, friction marks, rubbing and the like. The processing fluid jetting section comprises an air flow jetting portion and a liquid flow jetting portion, of which respective nozzles are movable and can change fluid jetting forces according to kinds of cloths, weights and a processing object to regulate a mixing ratio of the air and liquid, thus facilitating regulation suited to dyeing and feeling improvement. Also, no cooling water is used in a cooling process but latent heat of vaporization produced by pressure control of a circulating air flow is made use of to realize energy saving, and a period of time for cooling is shortened and dissolved impurities in the processing liquid are discharged by a high temperature drainage, so that the cloth is prevented from being again contaminated and a series of processes ranging from a wetting process to a drying process can be performed in a short period of time.
