(57) [Summary] [Objective] To provide a device for single-sided plating of woven and knitted goods. [Constitution] In a device for electrolessly plating a woven or knitted fabric by a continuous method, a drum which is installed by partially immersing it in a plating solution in a plating tank and can rotate together with a running woven or knitted fabric, and An apparatus for single-sided plating of a woven or knitted fabric, comprising a drum which allows the woven and knitted fabric to enter, run, and discharge in a state in which the surface is in close contact with one surface of the woven or knitted fabric.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plating apparatus for forming a metal film on one surface of a woven or knitted material by electroless plating (also known as chemical plating).

[0002]

[Prior art]

 Conventionally, an electroless plating method has been typical as a method for plating a woven or knitted fabric.

In order to carry out continuous plating, an apparatus is used in which a woven or knitted material is dipped in an electroless plating solution and an electroless plating reaction is allowed to proceed on both sides of the woven or knitted material to form a metal film.

As a matter of course, according to the dipping method, a metal film is formed on the entire front and back surfaces of the woven or knitted material.

However, the woven or knitted product plated product thus obtained has a uniform metallic luster appearance, and the decorative functions such as the color and pattern of ordinary woven and knitted products are significantly impaired.

There is a demand for a single-sided plated product having one surface having a performance as a metal film and the other surface being able to make use of an aesthetic property such as a color or a pattern of a normal woven or knitted fabric without being impaired.

At the same time, from the viewpoint of electrical performance, a special woven or knitted fabric having both a conductive surface and an insulating surface can be obtained, which is highly useful.

In order to form the metal film only on the one side surface, the following method in which the front and back of the woven or knitted fabric are subjected to different chemical treatments can be given.

[0009] One side surface of a woven or knitted fabric that does not require a metal film is subjected to a water repellent treatment or a masking coat treatment, and immersed in an ordinary plating bath for plating treatment, and then a water repellent agent or a masking coating agent is chemically or chemically applied. It is physically removed to obtain a plated product on one side.

[0010]

[Problems to be solved by the device]

 The masking coat is applied before plating and peeled off after plating, which not only complicates the process and increases cost, but also has the drawback that the masking coating agent drops off and stains the plating solution, resulting in poor workability. .

According to the present invention, in order to economically and simply perform plating on only one side without performing such complicated processing, a metal film is formed only on one side surface in the same number of steps as a conventional plating apparatus. It is to provide a plating apparatus that can be formed.

[0012]

[Means for Solving the Problems]

 This invention is a drum which is installed by partially dipping it in a plating solution in a plating tank in an apparatus for continuously performing electroless plating on a woven / knitted fabric, and which is capable of rotating together with a running woven / knitted fabric, and An apparatus for single-sided plating of a woven or knitted fabric, characterized in that the woven or knitted fabric can enter, run, or discharge with its surface being in close contact with one side of the woven or knit fabric.

[0013]

[Action]

 The side of the woven or knitted fabric that does not require the formation of a metal film is in close contact with the surface of the contact drum by adjusting the guide roll before entering the plating solution, and the surface is in contact with the plating solution. Do not enter, run and run.

Therefore, on the surface of the woven or knitted material, the metal film forming reaction, that is, the reduction and sticking out reaction of the metal ion in the electroless plating solution does not occur.

On the other hand, the surface of the woven or knitted fabric which is not in close contact with the contact drum is brought into contact with the plating solution and a metal plating reaction occurs to form a metal plated film.

[0016]

【Example】

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory view of the continuous electroless plating apparatus as seen from the side in the traveling direction.

In the drawings, 1 is a woven or knitted fabric, which is conveyed in the direction of the arrow.

The electroless plating solution 3 is stored in the plating tank 2, and the level of the plating solution 3 is maintained at a constant position 7 by a mechanism for adjusting the level.

The woven or knitted fabric 1 is conveyed by the conveyance drive roll 4, and is brought into contact with the guide roll 6 capable of speed control and the contact drum 5 so as to be in contact with the plating solution, and to travel in and out of the solution. Be guided.

The guide roll 6 is arranged so that the position where the woven and knitted fabric 1 and the surface of the contact drum 5 start to come into close contact with each other and the position 8 where the woven and knitted fabric separates from the drum surface are always higher than the liquid surface position 7. ing.

That is, the transferred woven or knitted fabric 1 comes into close contact with the surface of the contact drum 5 at the position 8 via the guide roll 6 and then enters the plating liquid 3.

The electroless plating reaction proceeds on the surface not in close contact with the contact drum 5, but the plating solution does not come into contact with the surface in close contact with the drum, so that the plating reaction does not occur.

The woven / knitted fabric 1 leaves the contacting drum 5 at the position 8 after being discharged from the plating solution 3 while maintaining the one-sided contact state, and proceeds to the next step.

[0025]

As described above in detail, according to the present invention, one side of a woven or knitted fabric can be brought into close contact with a conventionally used plating device without any special one-sided treatment and can be operated together with the woven or knitted fabric. By installing the contacting drum, the metal film can be formed on one side of the woven or knitted material economically and easily in the same number of steps as the metal plating of the usual woven or knitted material.
