Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an apparatus for test steaming small samples of fabric during dyeing and printing of fiber fabrics.

(Conventional techniques and their problems) In the steaming test of test fabrics, which is carried out prior to dyeing and printing of fabrics such as various synthetic fiber knitted fabrics, conventional techniques In order to accelerate this process, a sample steaming device using superheated steam separate from the steamer body used for production processing has been used.

There are three basic and important conditions in steaming related to color development, and among these conditions, steaming temperature and steaming time must be technically controlled even with conventional sample steaming equipment. was possible.

However, regarding the humidity control of superheated steam, which has a large effect on color development, it is generally difficult to control the pressure inside the sample steaming equipment chamber with conventional test steaming equipment; There were drawbacks such as poor sealing performance; () poor air displacement performance brought in by small fabric samples; therefore, there were slight differences in the conditions within the steamer body for production processing. Therefore, the current situation is that a great deal of effort and time has been spent on each individual device in order to obtain compatibility in color development between the use of a sample steamer and the use of a production processing steamer.

In view of these circumstances, the inventors of the present invention have conducted extensive research to develop a test steamer that can accurately obtain color fixation of dyes by steaming on synthetic knitted fabrics, and have completed the present invention, which is highly effective. .

(Means for Solving the Problems) The present invention provides openings 3 and 4 at the upper and lower parts of the side wall 2 of the continuous high temperature steamer 1, and attaches a duct chamber 5 to the outside of the side wall to connect them. At the same time, a hanger for hanging the test cloth 12 is provided in the duct chamber, and shutters 6 and 7 are installed at the upper and lower ends of the duct end of the duct chamber to shut off superheated steam from the continuous high-temperature steamer. In addition, a fan 8 is installed to circulate superheated steam in the duct at the bottom, and a door 1 is used to take the test cloth in and out of the duct chamber.
The present invention provides a test steaming device characterized by being provided with a freely openable and closable valve 13 for releasing the pressure inside the chamber.

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

The drawing is a side view showing an example of the essential parts of the device of the present invention. Continuous high temperature steamer 1 in the drawing
Openings 3 and 4 are provided at predetermined positions in the upper and lower parts of the side wall 2, and a duct chamber 5 is attached to the outside of the side wall to connect them. Shutters 6 and 7 are installed at the upper and lower ends of the duct end of the duct chamber to shut off superheated steam from the continuous high-temperature steamer, and a fan is installed in the lower duct to circulate the superheated steam by a motor 9. The superheated steam in the attached continuous high temperature steamer flows smoothly inside the duct chamber. Further, a hanger 11 for hanging a test cloth 12 is provided inside the duct chamber, and a door 10 which can be opened and closed is provided outside the center of the duct chamber to facilitate attachment and detachment of the test cloth.
The duct chamber, which is the main body of the test steaming device illustrated in the drawing, is made of a stainless steel plate with a wall thickness of about 2 mm and has a cylindrical U-shape with a diameter of 250 to 300 mm. Of course, the size etc. are not limited to this.

To use the test steaming device according to the present invention, open the door 10 of the duct chamber, attach the test cloth 12 to the hanger 11, close the door, and then turn on the shutters 6 and 7 for blocking superheated steam. Open. Next, the superheated circulation fan 8 is operated to send the superheated steam in the continuous high-temperature steamer from the opening 3 toward the opening 4, thereby circulating the inside of the duct chamber. After steaming the test fabric for a certain period of time, shutters 6 and 7 for shutting off superheated steam are closed.

Next, the superheated steam in the duct chamber is discharged by operating the discharge valve 13, which is a valve that can be opened and closed to release the pressure in the chamber, and then the test cloth loading/unloading door is opened to take out the steamed test cloth. It will be held in

(Effects of the invention) As a result of uniformizing the steaming conditions that greatly affect the color development of dyes, the device of this invention produces color with high precision, similar to that of continuous high-temperature steamers used in production processing. Since reproducibility can be obtained, there is an advantage that the time and labor required for setting steaming conditions, checking steaming factors, etc. are completely eliminated.

Furthermore, compared to installing an independent sample steaming device, it is possible to achieve great effects such as the cost of equipment investment being greatly reduced, and its practical value is enormous.
