Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is directed to a high-temperature processing machine configured to effectively set and process long fabrics of various sizes with different widths to a predetermined width. The present invention relates to a liquid set processing device.

[Background of the invention]

There are two methods for continuously applying moist heat to industrially produced long fabrics, such as round body knits, woven fabrics, and open-cut knits, by applying moist heat while guiding them with tension rolls, and by applying moist heat in the width direction using a tenter. The former method of setting in the width direction using tension rolls causes variations in set dimensions and lacks accuracy in set dimensions. Particularly in the case of fabrics such as welfare fabrics that are difficult to adjust in width, there are problems such as poor setting properties to a predetermined width. In addition, when setting means using a tenter, it is necessary to change the width of the tenter depending on the width of the fabric to be set.
Furthermore, as the width of the tenter changes, the effective length of the shower nozzle for applying moist heat (hot liquid) to the fabric must be changed, so the structure of the shower nozzle becomes complicated, and as a result, the length of the tenter becomes more complicated. Problems also arise in terms of economic efficiency due to the complicated overall structure.

[Purpose of the invention]

The present invention has been made in view of these problems, and its first purpose is to set the fabric even if the fabric to be set is a fabric that is prone to selvage, expansion and contraction, such as an open-woven fabric. The process is to accurately set the size and width.

The second purpose is to make it possible to effectively set any width of fabric by following the change in the width of the fabric to be cut.

[Embodiments of the invention]

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

1 is open fabric, woven fabric, etc. (hereinafter referred to simply as fabric)
The apparatus for setting this fabric 1 is an open tenter 2 for tension-transferring the fabric 1 in the width direction, which has been pre-applied and impregnated with a treatment liquid in a liquid tank (not shown), and this open tenter 2. It is roughly divided into the set machine 3 which is installed next to the set machine 3.

The structure of the open tenter 2 is a well-known structure used as a conventional mercerizing device, etc.
Of course, the width interval of this open tenter 2 can be freely adjusted according to the width of the fabric 1 to be processed. ．． It has a 4□ frame. Since a known open tenter structure can be selectively used, a detailed explanation of the mechanism will be omitted.

Reference numeral 5 denotes an overfeed mechanism for overfeeding the fabric 1 to be tension-transferred to the open tenter 2. The setting machine 3 has a fabric guide drum 7 which is located in the setting chamber 6 and has liquid permeability, and the fabric to be guided and transferred to the fabric guide drum 7 is placed on the half-way portion of the drum 7. It has a presser roll 8 for pressing against the drum surface and a large number of high-temperature liquid injection nozzles 9 arranged between the presser rolls 8. Further, a tray 10 is placed inside the drum 7 to collect the high-temperature liquid blown out from the nozzle 9. 11
is a group of drying heat cylinders installed next to the setting machine 3.

The above is the structure of this example, but next we will discuss its operation':)
In other words, when the fabric 1 to be moist heat set is supplied to the open tenter through the overfeed mechanism 5, the open tenter 2 expands the fabric 1 in the width direction.
The structure is constructed under tension while being given sufficient overfeed to ensure that the structure is fully maintained. While the fabric 1, which is being transported while being stretched to a predetermined width, is being tensioned and transported by the open tenter 2, the spread state of the predetermined width is maintained, and the open tenter 2 performs the second spreading. The fabric 1 that has passed through the open tenter 2 is introduced into a setting machine 3, where it is guided by a guide drum 7, and the fabric 1 is suppressed from shrinking in the width direction by the pressing action of the presser roll 8. The guide transfer is carried out without causing ear wrap. Furthermore, while being guided and transferred to this guide drum 7, for example, 15
The fabric is set to a predetermined width by the thermal action of a high-temperature liquid at 0°C. The fabric 1 taken out from the setting machine 3 is heated and dried by a heat cylinder 11 to complete the setting process.

As described above, according to this embodiment, the fabric is first expanded to a desired thickness by taking into account the amount of shrinkage during setting using the open tenter 2 to be set, and then the fabric is spread between the guide drum 7 and the presser roll 8. The fabric is guided and transferred to the cloth to suppress shrinkage in the width direction and selvage while applying a high-temperature liquid to set the fabric to a predetermined width.This has the effect of accurately setting the fabric to a predetermined width. There is. In addition, during setting, the structure uses a guide drum and presser roll to suppress fabric shrinkage and selvage, so dimensional stability is improved and continuous setting processing is possible even for fabrics of various widths. It is possible, and the structure of the set machine can be simplified and the economical efficiency can be improved.

[Summary of the invention]

As described above, the present invention provides an open tenter for tension-transferring a fabric to be set and processed in its width direction, an overfeed mechanism for applying overfeed to the fabric tensioned on the open tenter, and It has a setting machine that sets the fabric by applying high-temperature liquid to the fabric led out from the tenter. It has presser rolls to suppress shrinkage and selvage of the fabric guided and transferred to the drum, and nozzles arranged between the presser rolls and for spraying high-temperature liquid toward the fabric guided to the drum. This is a high temperature liquid setting device characterized by the following.

〔Effect of the invention〕

Therefore, according to this device, the open tenter allows the fabric to be expanded in anticipation of shrinkage during setting processing using high-temperature liquid.
Since the cloth is then spread, it is possible to reliably finish the width of the cloth to a predetermined width after the setting process using the high-temperature liquid.

In addition, during set processing, the drum and presser roll prevent the fabric from shrinking in the width direction and curling up, so it is not limited to the amount of fabric to be processed, and even fabrics of various widths can be processed continuously. Moreover, there is an effect that set processing can be carried out reliably.
