Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fabric processing and transfer device in a fabric transfer pipe in an apparatus for performing processes such as scouring, bleaching, dyeing, etc. by circularly rotating a textile product, for example, a fabric to be processed, in an endless manner. Regarding.

The purpose is to treat the fabric to be treated at a low bath ratio and small flow rate in the fabric transfer pipe, to eliminate rope wrinkles, and to give a relaxing effect to the fabric and reduce foaming of the treatment liquid for uniform treatment. It is.

In conventional low liquid ratio liquid flow treatment equipment, the movement of the fabric in the fabric transfer pipe was carried out by the liquid flow from the injection nozzle that was ejected in the same direction as the movement of the fabric, so the fabric was relaxed in a straight line in the transfer pipe. The fabric is less likely to wrinkle or move, and more foaming occurs due to air being sucked into the processing liquid, which disturbs the alignment of the fabric in the fabric retention tank and often causes cavitation and surging phenomena in the pump. This caused a problem with the operation.

The present invention provides a liquid flow processing apparatus for processing textile products (hereinafter referred to as fabrics) by endlessly rotating an annular transfer passage consisting of a fabric transfer pipe and a retention section. Another aspect of the present invention is characterized in that a spray nozzle for spraying in a direction in which the fabric travels is provided, a liquid reservoir is provided in the fabric transfer pipe, and a nozzle for spraying in a direction opposite to the fabric's traveling direction is provided at the bottom of the liquid reservoir. A fabric drawing means such as an eccentric roll, a circular reel, or an elliptical reel is added to the exit side of the transfer pipe.

Next, embodiments of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 shows a conventional low liquor ratio jet dyeing machine, and FIG. 2 shows an embodiment of the present invention.

Reference numeral 1 denotes a fabric retention tank, and this and the fabric transfer pipe 2 form an annular processing passage.

7 is a pump, 8 is a heat exchanger, 9 is an injection nozzle that spouts liquid in the same direction as the fabric advances, 10 is a fabric drive reel, 12
The fabric is loaded and unloaded using the operation window.

Further, 14 is a fabric to be treated.

In FIG. 1, the fabric 14 in the fabric transfer tube 2 is moving linearly, so there is little chance of wrinkle movement, and rope wrinkle defects are likely to occur.

In addition, the liquid occupies the depth of the lower part of the fabric transfer pipe and moves with the fabric, and more than half of the upper part of the pipe is in the gas phase, which not only means that the liquid treatment of the fabric is insufficient. Air bubbles are brought into the fabric retention tank 1 and disturb the alignment of the fabrics in the fabric retention tank 1, often impeding the movement of the fabrics.

In order to overcome these defects, the present invention makes the fabric transfer tube 2 concave as shown in FIG. Separately from the spray nozzle 9 that sprays liquid, a spray nozzle 3 that sprays liquid in a direction opposite to the direction of fabric movement is provided at the lower center of the transfer pipe 2.

By doing this, the inside of the fabric transfer tube 2 is filled with liquid up to its outlet 4, and the fabric 14 is completely tension-free and meandering in the transfer tube 2, relaxing, and flowing through the transfer tube 2.
It moves to the outlet 4 of the same tube while being wrinkled inside, and is pulled out into the fabric retention tank 1 by an eccentric roll 5 located nearby.

The liquid is simultaneously discharged into the retention tank 1, passed through the nest plate 6 at the bottom of the tank, sucked into the pump 7, and recirculated through the heat exchanger 8 again to the injection nozzles 9 and 3 of the fabric transfer pipe 2. Ru.

In the figure, 11.13 indicates a liquid flow control valve.

Similarly, the injection nozzle 3 can be provided in the same direction as the fabric advances, but from the viewpoint of wrinkle-reversing the fabric, it is preferable to install the injection nozzle 3 in the opposite direction.

According to this invention, the milled surge of 100% wool, which often causes wrinkles and uneven processing with conventional jet dyeing machines, can be eliminated.
It is possible to obtain a product that is uniform and has a good texture without causing wrinkles or uneven processing, and the effect is very large.
