Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an efficient continuous high-frequency heating method for fabric processing.

There have been many reports on the use of high-frequency heating in dyeing E to date, such as the III Society 1671゜51-1671-
352$2.52-5029. @Kaimei 5O-24581
, 50-48075, 50-8505, and the literature "Dyeing Research" (Vol. 24, No. S, 1980), etc., but if you examine these patent documents in detail from the perspective of practical application, you will find the following. There is an interlayer point.

1) The wavelength of high frequency that can be used for industrial purposes is 915 MI
Iz.

It is 2450MI [s and when irradiating directly to the fabric, it is
Heating is extremely difficult.

(!) Due to the high transmittance of high-frequency waves, the thermal efficiency is poor when irradiating a single piece of fabric.

(3) Even with internal heating using high frequency, the dyeing process requires a certain amount of timing for the dye to diffuse internally.

The following nine methods have been considered to solve these problems.

(1) There are various methods on the market to ensure uniform heating, such as increasing the number of high-frequency generation points, using a fan to cause diffuse reflection of high-frequency waves, and using reflected waves from WaS walls instead of direct irradiation. It is also an essential condition to increase the frequency of high-frequency irradiation.

(!) As a method to improve the irradiation efficiency, there is a method of irradiating high-frequency waves by rolling the fabric, stacking the fabric, and then irradiating the fabric with high frequency waves. -85585, or AlW Tex Reaction #4 (Literature Staining Research Vol. 24, No. 5, 1980), which has recently been commercially available from Jukin Industries, Ltd., can be seen.

(To) The method for determining the timing of heat treatment is as described above (!
) of the method of stacking and irradiating rolled up fabrics.
The fabric (
101') in a meandering manner.

As mentioned above, various types of counter currents have been used, but all have drawbacks.

First, increasing the frequency of high-frequency irradiation leads to increased equipment investment costs and decreased thermal efficiency. In addition, although the batch type irradiation method seems to be good at first glance, there is a limit to the size of the dyeing loft.

There is a concern that unevenness may occur in the inner and outer layers during winding, and there is a large heat loss when the wound fabric is taken out of the heat treatment zone.

In addition, as shown in Figure 5, the method of transporting the fabric requires high costs for uniform irradiation equipment, the need to enlarge the heat treatment zone to ensure timing, and the fact that the fabric surface is in contact with the gas phase IC. Problems such as the occurrence of heat treatment spots due to partial drying remain.

The present invention was developed as a result of intensive research and development on these problems in view of the current situation.

The purpose of this invention is to obtain an extremely efficient continuous high-frequency heating processing direction for fabrics that does not have the above-mentioned problems.

In order to achieve this object, the present invention has the following configuration.

That is, the present invention involves continuously high-frequency heating of the overlapping portion while winding a moisture-toned chestnut fabric to which a dye or finishing agent has been applied in a cylindrical shape, and heating the overlapping portion from the innermost layer of the overlapping portion. This is a continuous high-frequency heating processing method for fabric, which is characterized by sequentially taking out wrinkled fabrics and transferring them.1 According to the method of the present invention, it is possible to process fabrics most efficiently and uniformly and continuously. .

The method of the present invention will be explained in detail below with reference to one drawing. 1st
The figure is a side sectional sketch showing an example of a high-frequency heating continuous processing apparatus for fabric used in the method of the present invention. The fabric (υ) is applied with a dye solution or a resin processing agent in the dapping tank (2), and is wrung out evenly with a mang. What is the thickness of the layered wheels?

Although it varies depending on the type of delicate cloth, processing distance, and other reaction conditions, 9 usually the number is about 2 to 201.0 The wrapped cloth (2) is taken out at the bottom layer and arranged at 45 with respect to the cloth direction. The cloth is deflected perpendicularly to the traveling direction of the cloth by the touch shaft (FIG. 2), and is guided outside from the heat treatment zone (b) through the outlet (8). In addition.

The term "heat treatment zone" as used herein means a region where the fabric is subjected to high-frequency heating in saturated steam.

High frequency waves are irradiated from a high frequency generator (11) through a conduit tube to a heat treatment zone (b) through an irradiation port (b). So is a device that scatters high frequencies to improve uniformity (2)
is a steam supply port for filling the heat treatment zone with saturated steam.

Note that the cloth feed roll (7) that performs one-layer winding is strongly driven as necessary. FIG. 2 is a perspective view of the movement of the fabric shown to facilitate understanding of the fabric conveyance mechanism, in which the fabric (1) is introduced into the heat treatment zone from the inlet and wound around the portion Ql for a certain period of time. Subsequently, the direction of movement of the cloth is changed from the lowest layer of the winding section (end) using the touch rod α4, and the cloth is guided out of the heat treatment zone through the exit.

The direction of movement of the drawn out fabric may be changed to the right angle direction, but 1. Normally, from the standpoint of workability, as shown in Figure 2, the direction of movement of the fabric is changed to the cloth inlet using the touch rod (G) again at the top of the container. Return it in the same direction and proceed to the next process.

In the method of the present invention, after dye liquid, resin liquid, etc. are uniformly applied, the fabric is subjected to high frequency heating while being wrapped in layers in a cylindrical shape as shown at 0JIC in Figures 1 and 2. The generated heat does not escape to the outside of the wrapped cloth and stays inside, so dyeing and resin fixation on the cloth are extremely efficient. Further, in the method of the present invention, since the fabric is wound in layers as described above, a small processing apparatus is sufficient, and the equipment investment cost is small.

In addition, according to the method of the present invention, fabrics can be treated continuously, so it is extremely efficient without the inconvenience of a batch method.
