Description

Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to a tenter that continuously spreads and transfers a long fabric, and a liquid application method that sprays high-temperature liquid toward the fabric that is spread and transferred by the tenter. Pre-treatment of fabric by means of
The present invention relates to a continuous wet heat processing apparatus for fabrics that can perform dyeing, printing color development, weight loss set processing, etc. continuously and at high speed.

[Background of the invention]

Conventional methods for processing industrially processed long fabrics, such as pretreatment, weight loss, dyeing, color development, and setting, using continuous moist heat reactions include the methods developed by the present inventors, for example. It has been proposed and known to carry out the above treatment by continuous moist heat using a wet heat reaction chamber such as a Purple Range (trade name of Shandong Iron Works Co., Ltd.) or a high pressure steamer. When used in a microwave oven, the purpose is mainly to pre-treat the fabric, and it is not suitable for dyeing, coloring, setting, etc., and is almost impossible. In other words, when using the purple range,
Because the fabric sent into this purple range is folded and piled up, it is sequentially subjected to moist heat treatment.
Almost no tension is applied in the length direction of the fabric, and the fabric can be contracted, but as the fabric is sequentially shaken and folded, wrinkles occur at the folded portions, and further processing at the armpits occurs. Unevenness occurs, making it difficult to achieve the desired pretreatment or processing such as dyeing. In addition, when using a high-pressure steamer, the fabric is guided by a guide roll and passed through the steamer can continuously without folding the fabric, which can suppress wrinkles and uneven processing. As the fabric is guided in a meandering manner by a large number of guide rolls placed inside the steamer can, tension is applied in the length direction of the fabric, which makes it impossible to measure the width of the fabric. There was a problem in that the fabric was likely to be processed with inferior precision.

With conventional reaction processing equipment such as purple ovens or high-pressure steamers, it is difficult to perform cleaning treatment after the reaction with chemical solutions in the same reaction processing equipment, so there are many A cleaning tank must be installed, which inevitably increases equipment costs, water, and thermal energy consumption.

[Purpose of the Invention] The present invention has been made to solve these problems, and it is possible to perform processes such as reaction treatment → cleaning → setting → drying → cooling by simplifying the mechanism and using a single low-cost processing device. It is an object of the present invention to provide a continuous liquid processing apparatus for fabrics that can produce a series of processing processes at high speed and with good quality.

[Embodiments of the invention]

The present invention will be explained in detail below based on embodiments shown in the drawings.

This embodiment is an apparatus that can continuously perform a series of processes on fabrics, such as dyeing, resin processing, pretreatment, etc., followed by washing, drying, and cooling. It is a fabric to be treated. This fabric 1 is fed into a treatment liquid tank 2 designed to have a low bath ratio, and in the treatment liquid tank 2, the associated treatment liquid (caustic liquid during pre-treatment, caustic liquid during dyeing treatment, A dye liquor (or a resin liquor during resin processing) is applied and impregnated. The fabric 1 impregnated with the treatment liquid is fed into a high-temperature water tank 3, the swelling of the fabric 1 is measured, and then fed to a tenter 5 via an overfeed roll 4. This tenter 5 is a tenter that cradles both sides of the liquid-filled and swollen fabric 10 and transfers the fabric while applying a rectangular tension force in the width direction of the fabric.
A well-known structure can be used for the tenter 5. The total length of this tenter 5 is divided into four processing zones from the fabric introduction side to the fabric output side.■), (C1, (D
) The processing zone (D) is divided into a timing zone, a processing zone (D) is a reaction cleaning zone, a processing zone (C) is a drying zone, and a processing zone (D) is a cooling zone. . In the treatment zone (working), 6 is a group of high temperature and humid fluid jet nozzles for spraying high temperature hot water from the upper side of the fabric 1 being transferred under tension by the tenter 5, and is also used to spray the fabric 1 onto the fabric 1. A suction group 7 for suctioning and recovering the hot water impregnated into the fabric is disposed on the lower side of the fabric. Reference numeral 8 denotes a suction pump, and a button is provided so that the recovered liquid sucked by this suction pump 8 can be put into a liquid storage tank 10 through a filter 9. Reference numeral 11 denotes a pressure canister in which high pressure and high temperature are maintained, and the inside of this pressure canister 11 is maintained at a high temperature atmosphere of, for example, 150° C. by feeding pressure steam. Reference numeral 12 denotes a flexible pipe disposed inside the pressure canister 11, and by supplying the liquid in the liquid storage tank 10 into the flexible pipe 12 with the pump 13, the nuclear liquid rises to a temperature close to the temperature inside the pressure canister 11. A high temperature liquid (hot water) close to approximately 150℃
The above-mentioned nozzle group 6 sprays the cloth 1 at the same time. In the treatment zone (C), a plurality of dry hot air spray nozzles 14 are arranged in the direction of transport of the fabric, and these nozzles 14 spray dry hot air at approximately 130° C. toward the fabric 1, for example. It is. In the treatment zone (D), a number of cold air injection nozzles 15 are arranged in the direction of transport of the fabric, and from these nozzles 14, cold air of, for example, 20 to 25° C. is injected toward the fabric. It is something.

Next, to explain its effect, the fabric that has been impregnated and adsorbed with the treatment liquid in the treatment liquid tank 2 is exposed to hot water of around 150°C in the high-temperature liquid water tank 3, and swells. The permeability of the liquid into the fabric is increased, and width adjustment by the tenter 5 becomes necessary. Next, the fabric is transferred to the tenter 5 and first runs through a timing zone, and while passing through the timing zone, a timing is obtained that allows the treatment liquid to easily and reliably react to the fabric. Then, while this fabric 1 passes through a processing zone (can),
Hot water of, for example, close to 150°C is sprayed from the nozzle group 6 under pressure on the fabric 1, so that the treatment liquid that has already been temporarily attached penetrates into the inner core of the fabric in about a few seconds and causes a moist heat reaction. At the same time, the unreacted and reacted chemical liquid molecules fall off due to the jet force of the hot water, and the cleaning action also works at the same time.Therefore, this treatment zone FB) accelerates the wet heat reaction and cleaning of the fabric. It is something that The fabric thus subjected to the reaction washing treatment is then dried by receiving dry hot air in the next drying zone (C), and then cooled and set in the treatment zone (D) to continuously obtain the desired treated fabric. be.

In this way, in this example, the fabric transferred by the tenter is in the timing zone, the reaction cleaning zone (■),
By passing through the drying zone (C) and the cooling zone (D) in this order, the desired treated fabrics, such as pretreated fabrics, dyed fabrics, resin-treated fabrics, etc., are made into products.
