Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is a continuous contact pressure device for fabric that is capable of preventing selvage of continuously transported fabric or applying a fixed amount of impregnating liquid to the fabric. It is related to.

[Background of the idea]

Knitted fabrics have the property of producing selvage at the edges of the fabric, so for example, when printing dye is applied to the surface of the knitted fabric and then transferred, selvage is produced after the dye is applied, and this selvage is This has the drawback of causing uneven dye application at the edges of the fabric. Conventionally, in order to eliminate this selvage of the fabric, methods have been used such as using a clip tenter, applying glue to both sides of the knitted fabric, or tucking it into a cylindrical shape. However, in the above-mentioned clip tenter, there is a problem that the knitted fabric is stretched due to the tension of the clip tenter, and the selvage prevention device itself is complicated. In the case of gluing, the gluing agent falls off during processing and loses its anti-slip effect, causing various problems.

Furthermore, since this selvage prevention setting means applies glue to both sides of the fabric and the round body, the portions to which the glue and chemicals are applied are ultimately cut off. It had to be discarded, which required a cutting process, and it also had the disadvantage of causing 8-10% fiber waste due to cutting.

Alternatively, for example, a long piece of fabric may be continuously passed through a steamer can that retains a desired amount of moist heat, and the moist heat inside the steamer can be applied to the fabric passing through the steamer can to pre-treat or dye the fabric. As a device for performing this process efficiently and at high speed, a liquid tank or a shower device is provided to apply liquid to the fabric being transferred in the high-pressure steamer can, and the excess impurity applied by these liquid applying means is also installed. Some are equipped with squeezing rolls for squeezing the liquid.

However, since this squeezing roll generally uses a rubber roll, it tends to deteriorate due to the high heat inside the high-pressure steamer can, and there are other problems such as the pressurizing effect of the squeezing roll squeezing out more liquid than necessary. It was hot.

[Purpose of invention]

The present invention was developed to solve these conventional problems, and it is possible to obtain a fabric contact pressure that can effectively prevent selvage from forming on the surface of the fabric being transferred or adjust the liquid content to the fabric. The purpose of this invention is to provide a continuous pressure device for fabrics that can be applied to fabrics.

[Example of idea]

The present invention will be explained in detail below based on the embodiments shown in FIGS. 1 to 4.

In FIGS. 1 to 3, reference numeral 1 denotes a moist heat treatment chamber under normal pressure, and within this moist heat treatment chamber 1, guide rolls 3 are arranged to guide and transfer the fabric 2 to be treated in a meandering manner. There is. Reference numeral 4 denotes a liquid tank for applying a treatment liquid to the fabric guided and transferred by the guide roll 3, and the treatment liquid can be repeatedly applied to the fabric 2 transferred by this liquid tank 4. can. 5, 5' are liquid tank 4
This touch bar is attached to both the front and back sides of the liquid-impregnated fabric 2 pulled out from the holder to adjust the liquid content of the fabric (sweeping out excess liquid) or to prevent the fabric 2 from curling up.
Since the gist of the present invention is a device for continuously contacting cloth with the touch bars 5, 5', this device will be explained below with reference to FIGS. 2 and 3. Reference numeral 6 denotes a pair of fixed frames fixed inside the moist heat treatment chamber 1, and these fixed frames 6 include:
Two horizontal elongated holes 7 and 7' are formed, respectively.
Support shafts 8, 8' are loosely fitted into these horizontal elongated holes 7, 7' so as to be movable in the longitudinal direction of the horizontal elongated holes 7, 7'. It is supported by a position adjustment rod 10 whose position can be adjusted, and its support shafts 8, 8' can be fixed at appropriate positions within the horizontal elongated holes 7, 7'. The upper ends of arms 11 and 11', which are formed in a generally doglegged shape on their side surfaces, are attached to the respective support shafts 8 and 8'. is supported.

The above is the structure of this embodiment, but one touch bar 5, that is, the touch bar 5 that comes into contact with the surface of the fabric.
is suspended from the fabric arm 11, and the touch bar 5' that contacts the back side of the fabric is suspended from the arm 11'.
is brought into contact with both sides of the fabric by its own weight. Therefore, by operating the handle 9 to change the horizontal force of the touch bars 5, 5', the contact pressure between the touch bars 5, 5' and the fabric can be adjusted steplessly from zero accurately and easily. This method has the advantage that the liquid content of the fabric 2 can be adjusted or the fabric can be prevented from becoming selvedge. In the above embodiment, the moist heat treatment chamber used was one under normal pressure. However, if the above mechanism is provided in the introduction passage 13 of the high pressure moist heat treatment chamber 12 as shown in FIG. It can be applied very effectively for prevention. Further, the fulcrum position of the arms 11, 11' and the shape of the arms are particularly limited as long as the touch bars 5, 5' suspended by the arms generate a horizontal component force in the direction of fabric contact pressure. It's not a thing.

[Summary of the idea]

As described above, the present invention allows the front and back touch bars, which are positioned parallel to both the front and back sides of the fabric being guided and transported by guide rolls, to generate a horizontal component force in the direction of contacting the fabric. This is a continuous contact pressure device for fabric, characterized in that the arm is fixed to the lower end of an arm, and the upper end of the arm is pivoted in a suspended state to a support shaft provided so as to be able to adjust the position in the horizontal direction. .

[Effect of idea]

Therefore, according to this device, the touch bar is brought into contact with the fabric surface by the horizontal component force of the touch bar due to the weight of the arm and the touch bar, so the touch bar is brought into contact with the fabric surface with a flexible contact force. As a result, it is possible to effectively extract excess impregnation impregnated into the fabric or prevent the fabric from becoming selvedge. In addition, since the horizontal component of the touch bar can be adjusted by adjusting the position of the spindle, it is possible to adjust the amount of exploitation and the force to prevent selvage, depending on the quality of the fabric or the amount of liquid applied. be.
