In general, the chain tape is dyed according to the hue of a cloth (for example, clothes, bags, etc.) on which the fastener tape including the fastener tape is attached. Therefore, chain belts of various hues are usually prepared in advance. However, the fact that the chain of a plurality of colors is stored as an inventory is itself a management burden that cannot be ignored. When ordering a fastener chain of a specific color from a customer, the dyed chain tape is taken out from the storage place, and the fastener element is attached to the fastener tape, and then the fastener element is subjected to treatment (for example, surface treatment such as grinding or oxidation). In the case of the order, it is required to go through a number of steps after accepting the order, thereby accepting the extended delivery time of the supplied product (for example, a zipper, a zipper chain or a fastener chain) from the customer.

In addition, the fastener chain is formed by mounting a plurality of fastener elements on the chain belt. The zipper chain is formed by the pair of left and right chain links. The zipper is a zipper chain that is inserted into the zipper head and includes a stop as appropriate.

Based on the above, the inventors of the present application found that the following method is meaningful in that an undyed fastener chain is prepared for attaching a fastener element to a fastener tape, and then, the fastener element of the fastener chain is selectively coated, and then , dye the fastener chain. In this method, since the fastener element is applied during the dyeing of the fastener strand, the fastener element is protected, and the fastener element during dyeing is prevented or suppressed from deteriorating. Further, a step of attaching a fastener to the fastener tape or a coating step of the fastener may be provided before the dyeing step. The fastener chain managed as inventory is an undyed plain portion shared between various colors, reducing the burden of inventory management. Can The plain chain of the fastener chain managed by the stock is dyed to the color specified by the customer, and the necessary steps are followed (the step of cutting to a predetermined length, the step of installing the stopper, the step of passing the zipper head, etc.) By paying for the goods, the delivery time can be shortened.

It is desirable to coat the outer surface of the element as closely as possible in a state in which the element is attached to the side edge portion of the fastener tape. According to this aspect, in a non-limiting embodiment, in order to selectively apply the element to the element, a conductive element is used as the element, and the conductive element is electrocoated using an aqueous coating. Installed. Since the aqueous coating is used, the liquid of the aqueous coating adheres to the un-positive or negatively charged chain, but the adhering liquid can be relatively easily removed in the subsequent step. On the other hand, on the exposed surface of the conductive element, the aqueous coating material is deposited and accumulated by the transfer of electric charge, thereby forming a coating film containing the aqueous coating material. Therefore, it is possible to avoid the case where the coating film on the conductive element is also removed when the liquid of the aqueous coating adhered to the fastener tape is removed. Further, the coating film may contain a precipitated water-dispersible resin, and the pigment may be contained in the case where the pigment is dispersed in the aqueous coating liquid, and may further contain other components. According to the embodiment, the coating film is colored, or not colored, or is transparent.

After the adhesion liquid of the aqueous coating material is removed from the fastener tape, the coating film on the conductive element is fixed, whereby a coating film which can be more sufficiently subjected to the subsequent dyeing step can be obtained. Even if the fastener tape obtained by the above method is dyed, the coating film on the exposed surface of the conductive element acts as a protective film for the conductive element, thereby suppressing deterioration of the conductive element. According to the electrodeposition, most of the exposed surface of the conductive element is covered with a coating film, thereby sufficiently protecting the conductive element. Moreover, according to this method, it is possible to construct a supply system of products that are fundamentally different from the previous ones, thereby The delivery time of the goods is shortened and contributed.

The conductive element is an electrically conductive element, and is not limited to a metal element, and includes a conductive resin element, and may have other types of elements as long as it has conductivity. As an example, copper, a copper alloy (red copper, zinc white copper, etc.), an aluminum alloy, stainless steel, titanium, zinc, etc. are mentioned. As another example, a resin-made element having a surface-plated surface can be used. The material used in the plating can be, for example, the metal. Examples of the resin material include polyacetal, polyester, polyamide, polypropylene, acrylic, and the like. From the viewpoint of ensuring high strength, polyacetal is sometimes used. The surface of the plated resin element can also be subjected to any surface treatment. As such, the conductive elements can comprise a variety of materials.

The more detailed description of the invention disclosed in the application of the invention is not limited to the scope of the invention as defined by the appended claims.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The various embodiments and features disclosed are not individually independent, and need not be described in detail, as long as those skilled in the art can appropriately combine them, and the synergistic effect of the combination can be grasped. The repeated description between the embodiments is omitted in principle. The main purpose of referring to the drawings is to explain the invention and can be appropriately simplified.

<First embodiment>

The first embodiment will be described with reference to Figs. 1 to 5 . Fig. 1 is a schematic view for explaining steps of a method for producing a fastener tape and a method of dyeing the same. Fig. 2 is a schematic view showing an apparatus used in the manufacture of a fastener stringer. Figure 3 is a view showing an outline of an exemplary slide fastener Front view. Fig. 4 is a schematic view schematically showing a plurality of conductive elements attached to side edges of a fastener tape. Fig. 5 is a partially enlarged schematic view showing the zipper of the illustration, showing a state in which the left and right conductive elements are in meshing state by a partial schematic cross section.

As shown in FIG. 1, the method for manufacturing a fastener tape and the dyeing method 100 may include steps 110 to 160. Of course, the method of manufacturing the fastener tape and the dyeing method 100 may additionally include steps other than steps 110 to 160. In the following description, steps are performed in the order of step 110, step 120, step 130, step 140, step 150, and step 160. Step 150 can be omitted, and this point is the same in other embodiments to be described later. It should be noted that the order of steps 110 to 160 will be changed according to the embodiment.

First, a plain fastener chain is supplied in step 110. The plain tooth chain is a fastener chain containing a plain chain. Step 110 includes providing a fastener chain in which a conductive element is preliminarily attached to a side edge portion of the fastener tape. Step 110 can include the step of mounting a conductive element on a side edge of the chain.

When a metal element is attached to the side edge portion of the fastener tape, the pair of leg portions of the metal element are pressed, whereby the side edge portion of the fastener tape is sandwiched between the pair of leg portions. The side edge portion of the chain belt is sometimes made thicker than the portion of the other chain belt.

When a resin element is attached to the side edge portion of the fastener tape, injection molding is performed in a state where the side edge portion of the fastener tape is placed in the mold cavity. The conductivity imparted to the resin element can be achieved by coating the resin element with a conductive film. Alternatively, a resin material in which a conductive filler is dispersed is used.

In the next step 120 to step 140, selectively to the plain tooth chain The fastener element is coated, whereby a coating film is formed on the exposed surface of the fastener element of the plain fastener chain.

In detail, the electrocoating is performed in step 120. Specifically, in step 120, a coating film is formed which is formed by depositing an aqueous coating on the exposed surface of each conductive element of the fastener tape based on electrocoating, in the formation of the coating film. The solution of the aqueous coating adheres to the chain of the fastener chain. The electrocoating may include: immersing the fastener tape in an aqueous coating liquid in which the aqueous coating material is dissolved, and bringing the electrode on the side of the aqueous coating deposition side into contact with the element immersed in the aqueous coating liquid.

In the electrocoating step, a dyeing tank for storing an aqueous coating liquid in which an aqueous coating material is dissolved, and a pair of electrodes disposed in the aqueous coating liquid of the dyeing tank for energizing the liquid are respectively connected to The power supply of the pair of terminals of the pair of electrodes transports the fastener belt or the fastener chain of the fastener chain through the dyeing tank. In the case of an anionic water-based paint, the positive electrode is in contact with each element in the liquid, and the aqueous paint is deposited on the surface of the element acting as a positive electrode in response to the energization of the aqueous coating liquid. The electrode can also be brought into contact with a plurality of fastener elements at the same time, and the electrodes can be sequentially contacted with the respective fastener elements. "Contact" as used in this paragraph refers to electrical contact and does not necessarily require physical contact, but in some forms it is desirable to have physical contact.

Those skilled in the art can specify an appropriate applied voltage magnitude or voltage application time and form a coating film of a suitable thickness in each of the fastener elements. The applied voltage can be selected, for example, from the range of 30V to 240V. The voltage application time required for the electrocoating of each element is selected from the range of 10.01 seconds to 30 minutes.

It is not necessary to immerse the fastener string in the aqueous coating liquid as a whole. I also envision a chain of teeth A part of the belt, such as a fastener element and a side edge portion to which the fastener element is attached, is selectively immersed in the aqueous coating liquid. In most cases, it is expected that it is difficult to prevent the liquid of the aqueous coating from adhering to the chain.

One of an anionic type and a cationic type can be used for the water-based paint. The aqueous coating may comprise a water-dispersible resin. The water-based paint may contain an inorganic pigment in addition to the water-dispersible resin. For example, the aqueous coating material may include a thermosetting water-soluble polyester resin and an inorganic pigment. In some embodiments, 10 parts by mass or less of the inorganic pigment is added to 100 parts by mass of the resin. In another embodiment, 5 parts by mass or less of the inorganic pigment is added to 100 parts by mass of the resin. It is envisaged to use various inorganic pigments, and it is also conceivable to use a combination of different kinds of inorganic pigments. It is also envisaged to use an aqueous coating which is not added with an inorganic pigment. Further, the inorganic pigment is also extracted into the coating film when the water-dispersible resin is precipitated.

The electrocoating step may further include removing a film of the aqueous coating deposited on the surface of the electrode in the aqueous coating liquid immersed in the water-dispersible resin. In the case where the electrode for causing the element to be charged with the desired conductivity type (positive or negative) is immersed in the aqueous coating liquid, it is feared that the surface of the electrode in the liquid during the electrocoating process is also covered with the film of the aqueous coating. In view of this, it is preferred to periodically remove the surface film of the electrode in the liquid to ensure good electrical contact between the electrode and the element in the liquid.

Thus, a film of an aqueous coating material, that is, a coating film, is formed on the exposed surface of the conductive element of the plain fastener chain. When a coating film is formed on a conductive element, the exposure of the conductive element is hindered in the formation range of the coating film. Electric painting conditions can be used in the field The skilled person is determined depending on the thickness of the desired coating film or the range in which the coating film is formed. Those skilled in the art can also determine the number or contact area of the contacts of the conductive element and the electrode.

According to the nature of electrocoating, it is expected that most of the exposed surface of the conductive element is covered with a coating film. For example, the exposed surface of the conductive element after electrocoating is 1/10 or less of the area of the exposed surface of the conductive element before electrocoating, and in some cases 1/20 or less, in some cases. Below is 1/30 or less. According to the embodiment, the coating film is formed so as to completely or substantially completely enclose the conductive element of the plain fastener chain. However, in some forms, it is also expected that a part of the exposed surface of the conductive element is not coated with a coating film.

Preferably, the zipper chain is transported relative to the electrocoating groove and the zipper chain is immersed. In the zipper chain, if the left and right fastener elements are in the engaged state, there is also a slight gap in the meshed element. Therefore, electrophoresis of the aqueous coating material in the liquid is ensured by the gap, and a sufficient coating treatment for each element is achieved.

Next, in step 130, the liquid of the aqueous coating attached to the chain is removed. In the electrodeposition process in step 120, the liquid of the aqueous coating adheres to the chain. The chain tape is not charged, and therefore, the aqueous coating in the liquid is not deposited on the surface of the chain. Moreover, the chain belt is different from the conductive element and does not directly contact the electrode. Therefore, after electrocoating, the liquid of the aqueous coating attached to the chain can be easily removed. In some embodiments, the liquid of the removed aqueous coating is returned to the electrocoating tank for reuse.

The step of removing the liquid of the aqueous coating may include removing the liquid of the aqueous coating based on water washing and/or suction. Washing can include plain toothed belts after electrocoating Put it into the sink. The water wash can include agitating the plain tooth chain in the sink. Suction includes aspirator-based work to remove liquid from the aqueous coating of the fastener tape attached to the plain fastener chain.

Next, in step 140, a fixing process is performed on the coating film on the exposed surface of the conductive element. The coating film is a film formed by precipitation of an aqueous coating. By performing the fixing treatment, it is possible to suppress the peeling of the coating film from the conductive element.

The aqueous coating material may include, for example, a thermosetting water-dispersible resin. In this case, the coating film deposited on the exposed surface of the conductive element is cured by heating the plain toothed fastener tape, and the coating film is fixed to the conductive element. In addition, this process is also called "burning".

A heat-curing water-dispersible resin having a lower curing temperature should be used. In the case of conveying the plain fastener chain in order to pass through the heater, damage to the fastener tape can be reduced, and the coating film can be quickly hardened. As an example, the water-based dispersion resin contained in the aqueous coating material has a curing start temperature of 200 ° C or less, in other cases 150 ° C or less, and in other cases, 130 ° C or less. Further, according to the embodiment, the fastener tape is protected by the mask tape, and the execution of the baking at a higher temperature is allowed.

The liquid of the aqueous coating attached to the fastener tape may be removed without being removed. In this case, a hardened coating film is also formed on the chain. Preferably, the hardened coating film on the chain tape is removed by any method.

According to the description, it can be understood that the conductive element of the plain fastener chain is selectively coated in steps 120 to 140, whereby the exposed portion of the conductive element of the plain fastener belt is coated by the coating film. Coated. In addition, the zipper chain can be subjected to electrocoating, liquid removal of the aqueous coating material, and fixing treatment of the coating film.

Next, in step 150, the plain fastener chain is stored. Additionally, step 150 can be omitted. From the viewpoint of the manufacture of the actual zipper, step 150 corresponds to storing a plurality of plain color fastener belts in a warehouse. Further, one or more drying treatments may be introduced between steps 120 and 150.

Next, the dyeing process is performed in step 160. For example, a plurality of plain toothed fastener tapes are put into the dyeing tank, and the plain toothed fastener tape is stirred, and in the process, the chain of the plain toothed fastener tape is dyed by the dye in the dyeing tank. In another example, a fastener tape is wound around a rotating device of a dyeing device, and a dye is sprayed on the rotating fastener tape, and the chain of the plain fastener chain is dyed in the process. The conductive element is covered by a hardened coating film. Therefore, it is possible to suppress deterioration of the conductive element, such as corrosion, during the dyeing process. Since the conductive element is coated with a coating film, a reactive dye is also allowed to be used. It is of course also possible to perform a dyeing process on the zipper chain.

Thus, a toothed belt or a zipper chain that completes the dyeing is provided. The fastener chain can have a chain of colors specified by the customer. Further, in some non-limiting forms, the fastener tape may also have fastener elements of a customer-specified color based on the pigment in the coating film.

After dyeing, cut the fastener chain or zipper chain to the specified length as needed, and install other zipper parts such as stoppers and zipper heads. This is the finished product of the zipper. Alternatively, the fastener chain or the fastener chain can be cut before the storage step. However, if the long zipper chain is dyed and then the zipper chain is cut, higher production efficiency can be ensured.

As understood from the description, steps 110 to 150 may be performed in advance before accepting an order from a customer. Therefore, it can reduce the acceptance of orders from customers. The number of steps to promote the shortening of the delivery time of the goods. The conductive element of the plain toothed belt is coated with a coating film in advance, so that deterioration of the conductive element during the dyeing process can be suppressed.

The apparatus or apparatus shown in Figure 2 can also be used in each of the steps. The function or meaning of the various devices can be understood from the description. The supply portion 210 may include means for attaching a fastener element to a side edge portion of the fastener tape. The supply unit 210 may include means for transporting the fastener chain, such as a roll to roll type device. The electrocoating device 220 may include a device capable of performing electrocoating, and may include the electrocoating tank, a pair of electrodes, a power source, and a conveying device.

The fastener chain is continuously conveyed by a roll-to-roll conveyance device. In the middle of the transfer, the fastener chain passes through the anionic aqueous paint bath, and during the passage, the positive electrode is sequentially brought into contact with each element, and a coating film is formed on the exposed surface of each of the conductive elements. At this time, the conditions for electrocoating are as follows.

<electrodeposition conditions>

(1) Transfer speed of zipper chain: 5m/min

(2) Applied voltage: 240V

(3) Water-based paint: low-temperature thermosetting water-based polyester resin coating without pigment added

After the zipper chain passes through the aqueous coating bath, the zipper chain is continuously conveyed by the roll-to-roll conveyance device, and the water-based paint liquid adhered to the chain belt is washed by water. Body removal. Then, the fastener chain is subjected to a baking treatment to harden the coating film of the coated element and fix it to the element. The baking was performed by heating the fastener chain at 130 ° C for 15 minutes, thereby hardening the coating film on the element. In this way, a fastener chain in which the element has been protected by the hardened coating film is produced. Then, the obtained fastener chain was put into a dyeing tank to carry out a dyeing treatment. Specifically, the dyeing was carried out using a disperse dye at 130 ° C for 30 minutes, and then the reduction treatment was carried out at 90 ° C for 10 minutes. No problems were observed in the fastener elements after the dyeing treatment.
