Description

[Detailed description of the invention] The present invention relates to a fabric processing device, and more specifically, the fabric is treated by bringing it into contact with a processing solution while circulating a long endless fabric in a spread state. The present invention relates to a fabric processing device.

BACKGROUND ART Conventionally, a wince dyeing machine and a jet dyeing machine are known as devices for processing textile products such as fabrics into long endless shapes.

In these devices, the fabric, etc. is usually hung in an endless manner from a reel or roll, the suspended part is immersed in a large bathtub, and the fabric, etc. is circulated in this state and passed through the bathtub for processing. Alternatively, the fabric, etc. is circulated by a jet stream or an overflow stream, and is processed by passing it in a meandering manner through a retention tank where the fabric, etc. can be temporarily retained.

However, in such an apparatus, the bath ratio, that is, the weight ratio of the material to be treated such as fabric to the treatment liquid is as large as 1:20 to 1:30, and a large amount of dyes and auxiliary agents are required, and water and steam are required. This method requires a large amount of liquid, making it uneconomical, and also has drawbacks such as a large amount of waste liquid, which is difficult to dispose of.

In order to solve this problem, low-liquid ratio processing equipment for fabrics, etc. has recently been developed and put into practical use. It was processed in a circular manner.

However, in such a rope-shaped apparatus for processing fabrics, etc., the fabrics, etc. can be transferred at high speed, and while it has the advantage of being able to obtain a rubbing effect on the material, when the amount of processing liquid is small, that is, the bath ratio is If the size of the fabric is reduced to a smaller size, the transfer of the fabric, etc. cannot be carried out smoothly, wrinkles are likely to occur, and the fabric, etc. must be untwisted using a scatcher etc. before being spread out before being transferred to the subsequent process. There was a problem.

An object of the present invention is to provide an apparatus that does not cause the above-mentioned problems even at low bath ratios and can process fabrics extremely efficiently.

According to the present invention, the fabric is treated by bringing the fabric into contact with a treatment liquid at the bottom of the treatment tank while circulating the fabric in a long endless shape in the treatment tank. An apparatus is provided, the apparatus comprising: a reel or drive roll for sequentially lifting the fabric from the treatment liquid at the bottom of the treatment tank; and a liquid level between the reel or drive roll and the treatment liquid at the bottom of the treatment tank. A spreading device for spreading the fabric provided between the fabric, and a fabric drawn out from the bottom of the processing tank downstream of the reel or drive roll, towards the fabric transferred via the reel or drive roll. A shower nozzle for spraying a processing liquid; and at least one cloth receiving scraper installed at an angle below the shower nozzle, the lower portion of which forms a processing liquid reservoir. It is characterized by becoming.

Hereinafter, preferred embodiments of the device according to the present invention will be described in detail with reference to the accompanying drawings.

In Figure 1, 1 is a sealed tank with a nearly circular cross section;
An entrance/exit 3 for the fabric 2 is provided.

Reference numeral 4 denotes a reel or drive roll, which serves as a drive source for lifting up the fabric 2 from the treatment liquid at the bottom of the tank 1 and transporting it.

Reference numerals 5 and 5' denote a pair of expander rolls disposed between the reel or drive roll 4 and the surface of the treatment liquid at the bottom of the tank 1, which expand the fabric 2 when it is pulled up.

The expander roll may be a curved expander roll or a screw expander roll.

The fabric 2 pulled up by the reel or drive roll 4 is passed between a pair of shower nozzle rows 6, 6' downstream of the reel or drive roll, and falls onto a first scraper 7 arranged at an angle. .

The fabric 2 that has fallen onto the first scraper then slides on the slope of the scraper 7 due to its own weight, is immersed in the treatment liquid in the treatment liquid reservoir 8 provided in the lower part of the scrape, and then flows into the overflow stream. At the same time, it falls onto the second scrape 9 below.

The second scraper 9 is formed of a perforated plate and separates the falling fabric 2 from the excess treatment liquid.

Next, the fabric slides on the slope of the scraper 9 due to its own weight, and reaches the processing liquid reservoir 1 at the bottom of the tank 1.
One cycle is completed when it is immersed in the processing liquid at 0.

On the other hand, a processing liquid suction pipe 11 is connected to the bottom of the tank 1, and is connected to a pump 12.

The processing liquid sucked into the pipe 11 is supplied by a pump 12 to the shower nozzle arrays 6, 6' via a heat exchanger 13 and a regulating valve 14.

With the device of the present invention constructed as described above, the fabric 2 pulled up from the treatment liquid is transferred to the expander rolls 5, 5.
', the treatment liquid is sprayed onto the fabric as it passes between the shower nozzle rows 6 and 6' via the reel or drive roll 4, and then falls onto the first scraper 7, and then as described above. It is transferred within the tank 1 and subjected to circulation processing.

In the above-mentioned apparatus, the first scrape 7 and the second scrape 9 are arranged so that they can be rotated about their upper parts as fulcrums so that their inclination angles can be adjusted, and can be properly fixed.

In the apparatus shown in FIG. 2, the fabric 2 passes through the shower nozzle rows 6, 6' and then passes through the first scrape 7a and the second scrape 7a.
b. After falling sequentially on the third scrape 7C, it falls onto the porous fourth scrape 9.

That is, in the apparatus of this embodiment, the fabric 2 is connected to each of the first, second, and third spray treatment liquid reservoirs 8a, 8b, and 8C.
It is repeatedly immersed in the treatment liquid.

According to the device of the present invention constructed as described above, (1) it is possible to process at a bath ratio of 1:5 or less, (2) the amount of dyes, auxiliary agents, etc. used can be greatly reduced; The amount of water and steam consumed can be reduced, ■ The amount of waste liquid is also reduced, and the labor required for waste liquid treatment can be reduced, ■ There is almost no wrinkles in the treated fabric, ■ There is no need for equipment such as a scarf, ■ Since the fabric is not forcibly rubbed by the liquid flow, there are many advantages such as almost no damage to the fabric.
