Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention provides a tenter that continuously spreads and transports a long fabric, and a night application means that sprays a high-temperature liquid toward the fabric that is spread and transferred by the tenter. Use it to pre-treat fabrics,
The present invention relates to a continuous liquid processing method for fabrics that can be dyed, printed color, reduced and set, 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, for example, the method developed by the present inventors. Purple range (product name of Shandong Iron Works Co., Ltd.),
Alternatively, it has been proposed to use a moist heat reaction chamber such as a high-pressure steamer to perform continuous moist heat to perform the above treatment, but in the case of using the purple oven mentioned above, the purpose is not to pre-treat the fabric. Therefore, it is not suitable for processing such as dyeing, color development, and setting, and in fact, it is almost impossible. In other words, when using the purple range, the fabric sent into the purple range is folded and piled up while being sequentially subjected to moist heat treatment, so the tension in the length direction of the fabric is almost completely reduced. First, the shrinkability of the fabric can be obtained, but since the fabric is folded one after another, wrinkles occur at the folded part, and uneven processing occurs in the armpit area, making it impossible to achieve the desired processing. The fabric that has been pre-treated in the Burple Range must be subjected to coloring, dyeing, setting, etc. in the next process using separate processing equipment, and it takes many steps and a long time to complete the series of processing. It was necessary. In addition, when using a high-pressure steamer, the fabric is guided by guide rolls and passed through the steamer can continuously without folding the fabric, which can suppress wrinkles and uneven processing. As the fabric is guided and transported in a meandering manner by multiple guide rolls placed inside the steamer can, tension is applied in the length direction of the fabric, making it impossible to measure the fabric in the width direction, resulting in processing with poor dimensional accuracy. There was a problem that it easily became cloth.

[Purpose of the invention]

The present invention solves these problems and produces a fabric that can be produced at high speed and with good quality through a series of processes such as pretreatment, color development, setting, and drying using a single low-cost processing device. The object of the present invention is to provide a continuous liquid processing method.

[Embodiments of the Invention] The present invention will be described in detail below based on embodiments shown in the drawings.

In this embodiment, dyeing, setting, and drying of fabric are carried out continuously in one apparatus, and 1 is the fabric to be treated. This fabric is fed into a dye liquor tank 2 designed to have a low bath ratio, and is impregnated with a predetermined dye liquor in the dye liquor tank 2. The fabric 1 impregnated with the dye liquid is passed through an intermediate dryer 3 using infrared rays to temporarily fix the dye to the fabric 1. Next, this fabric is fed to the tenter 4, and the fabric just before being fed to the tenter 4 is fed into the hot water application tank 5 to measure the swelling of the fabric, so that the tenter 4 can easily adjust the width. be. The tenter 4 is a tenter that clips both edges of a liquid-filled and swollen fabric and transfers the fabric while applying tension in the width direction of the fabric.The structure of this tenter 4 is based on a well-known structure. can be used. 6
is the fabric 1 being conveyed under tension by the tenter 4.
There is a group of hot water spray nozzles for spraying high-temperature hot water toward the fabric from the upper side, and a suction nozzle on the lower side of the fabric to suck and collect the hot water impregnated into the fabric. is installed. Reference numeral 8 denotes a suction pump, and the collected liquid sucked by this suction pump 8 is trapped so as to be put into a liquid storage tank 10 via an offshore filter 9.

Reference numeral 11 denotes a pressure vessel in which high pressure and high temperature is maintained, and the inside of this pressure vessel 11 is heated to a temperature of, for example, 180 mm by feeding pressure steam.
It can be maintained in a high temperature atmosphere of ℃. Reference numeral 12 denotes a flexible pipe disposed inside the pressure can 11, and by supplying the fluid in the liquid storage tank 10 into the flexible pipe 12 using the pump 13, the vaginal fluid rises to a temperature close to the temperature inside the pressure can 11. As a result, a liquid (hot water) with a high temperature of approximately 180° C. is formed and is sprayed from the hot water injection nozzles P and 6 toward the fabric. 14 is a group of hot air jet nozzles for drying provided next to the group of nozzles 6 on the tenter 4, and 15 is a group of cold air nozzles for cooling provided next to the group of hot air jets.

Next, to describe its effect, since the fabric 1 to which the dye solution has been temporarily fixed is supplied into the high-temperature solution application tank 5, the swelling properties of the fabric 1 are increased, and immediately after that, the fabric 1 is tenter-fixed. By being tensioned and transferred in the width direction by 4 and 9, the spread and transfer can be carried out easily and effectively. The fabric 1 thus spread and transferred will soon be sprayed with hot water of, for example, 180° C. under pressure from the nozzle group 6 onto the upper surface of the fabric, and the fabric fibers will swell due to the action of this sprayed hot water. Due to the swelling effect, the dye temporarily attached to the surface of the fabric is penetrated into the inner core of the fabric, and 1
Reactive dyeing of the dye is ensured. The hot water injected from the nozzle group 6 is heated to 180°C and pressurized to 710 degrees, so it is vaporized immediately after being injected from the nozzles and the temperature is rapidly lowered, so that the fabric can be heated as much as possible. By bringing the nozzle closer to the nozzle, relatively high temperature hot water can be applied to the fabric. Also, the distance between the fabric and the nozzle.

If it is spread out, the amount of vaporized steam applied will increase, which is advantageous for applying steam to the fabric (steaming).

The fabric 1, which has been subjected to moist heat treatment using hot water and/or steam from the nozzle group 6 and has been colored or dyed and set, enters the hot air drying zone and is exposed to the hot air jetted from the hot air jetting nozzle group 14. It is thoroughly dried.

The fabric that has been dried with hot air is cooled by the cold air from the nozzle group 15.
After being cooled, it is removed from the tenter 4 and transferred to the next process.

5. In this embodiment, since a high-temperature liquid is applied to the fabric just before it is strung on the tenter, the fabric just before it is strung on the tenter swells, and this causes the fabric to be stretched by force. It is possible to erect and transport it to a tenter without having to worry about it. Next, pressurized hot water of approximately 180°C is applied to the fabric, which is tension-transferred by the tenter in the r-opening direction, and is subjected to a moist heat reaction treatment, and then subjected to a series of drying treatment and cooling treatment, so that the fabric is tension-transferred in the r-opening direction by a single tenter. The coloring, drying, and staining processes are carried out continuously, and there is an effect that uniform and good quality processed fabrics can be produced from beginning to end.

In the above embodiments, dyeing or color development is described, but fabric pretreatment and weight reduction processing can also be carried out in the same manner. Caustic liquid is used in this pretreatment and weight reduction process, but in this invention, since the fabric is often exposed to air during the period from its moist heat to cooling, it also has the effect of preventing embrittlement of the fabric. Further, in the above embodiment, there are two high-hot water application zones, but one or more zones may be selectively installed, and the zones may be divided into high-hot water application and steaming.

[Summary of the invention]

As described above, in the present invention, a liquid-impregnated fabric that has been swollen by applying a treatment liquid and a high-temperature liquid is transferred while being spread in the width direction by a tenter, and then, while being spread and transferred by this tenter, this fabric is This is a continuous liquid processing method for fabric, which is characterized by sequentially performing a wet heat treatment, a drying treatment, and a cooling treatment.

〔Effect of the invention〕

Therefore, according to this processing method, the swollen fabric is placed on a tenter, so that it can be easily spread and transferred, and while the fabric is being spread and fed through this tenter, it can be subjected to the desired liquid treatment and drying process. Since a product that has been subjected to cooling treatment can be obtained, it is possible to continuously produce the desired spread set and the finished fabric subjected to liquid reaction treatment using extremely simple equipment (one tenter), reducing equipment costs. It is possible to cut 7t. Furthermore, since the processing is carried out using the same tenter, uniformity of processing is possible, and it is also possible to mass-produce processed fabrics of good quality.
