Description

  The present invention relates to a method for producing a base material on which a functional agent is fixed, and a functional agent fixing device.

  Conventionally, when a functional agent other than various dyes is fixed to a substrate such as a fabric, for example, dip dyeing in which the entire fabric is immersed in a functional agent solution is generally performed.

JP 05-033274 A

  However, when the functional agent other than the dye is fixed by dip dyeing, the functional agent penetrates not only to the surface where the functional agent needs to be fixed, but also to the inside and back surface of the fabric. Further, it is not always necessary to apply the functional agent to the entire surface of the fabric. For example, it may be sufficient to fix the functional agent only to the dyed portion. Therefore, the treatment by dip dyeing requires an amount of functional agent that is more than necessary, which increases the cost.

  The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to fix a functional agent other than a dye only to a necessary portion of a substrate such as a fabric. It is to provide a manufacturing apparatus and a manufacturing method.

The method for producing a substrate on which a functional agent is fixed according to the present invention includes a step of electrostatically providing at least one dry toner containing a functional agent other than a dye and a binder resin on a charged body;
Transferring the dry toner from the charged body to a base material; and fixing the transferred dry toner to the base material. Then, in the transfer step, by applying an electric field between the charged body and the substrate, dry toner on the charged body is caused to fly from the charged body to the substrate.

The functional agent fixing device according to the present invention includes a base material transport unit that transports a base material;
An electrostatic holding unit for electrostatically holding at least one dry toner containing a functional agent other than a dye and a binder resin on a charged body; the dry toner held in a charged body shape is transferred to the base material transport unit; A transfer section for transferring to a substrate conveyed by
A fixing unit that is provided downstream of the transfer unit on the substrate transport unit and fixes the transferred dry toner to the substrate. The transfer section applies an electric field applying unit that causes the dry toner on the charged body to fly from the charged body to the base material between the base material on the base material transport section and the charged body. Is provided.

  According to the present invention, since the dry toner containing the functional agent and the binder resin is transferred by flying, high transferability of the dry toner can be realized regardless of the surface state of the substrate, and a desired portion of the substrate other than the dye can be realized. It is possible to selectively fix the functional agent. The functional agent is a substance that modifies physical properties such as physical properties, chemical properties, biological properties, etc. of the base material, or that imparts new physical properties to the base material, and is other than a dye.

  In particular, it is preferable that the surface of the substrate has irregularities, and even in such a case, high transferability can be exhibited.

  Here, the base material can be, for example, a plastic film, a plastic sheet, a fabric, or the like. In particular, the surface of the fabric has complex irregularities such as gaps between fibers and valleys between yarns. Even in such a case, the functional agent can be transferred only to necessary portions.

  Since the dry toner is electrostatically transferred onto the charged body, the functional agent preferably has a charging property. In addition, even if the functional agent does not have chargeability, it can be implemented if the binder resin or the like has chargeability.

  In the transfer step, the electric field is applied to a state where a gap is provided between the dry toner on the charged body and the base material, or the charged body presses the dry toner against the base material. It is preferable to apply in such a state.

  The transfer unit has a gap between the dry toner on the charged body and the substrate, or the charged body of the transfer unit transfers the dry toner on the charged body to the substrate. It is preferable not to press.

  As a result, it is possible to suppress the dry toner from being biased to, for example, the most convex portion of the base material, and it is possible to reproduce an image of a good functional agent with little uneven density on the base material.

  Further, it is preferable that the charged body is a conductive photoconductor, and in the providing step, an image of the dry toner is provided on the conductive photoconductor.

  According to this, it is possible to easily form images of various types of functional agents using toner.

  Further, the functional agent fixing device, for example, provides a plurality of different dry toners to one charged body and then transfers the plurality of dry toners to the base material, and provides the dry toner to the charged body and then the base material. A plurality of toners onto a substrate by repeating the process of transferring the toner to different dry toners, or by transferring the dry toners from a plurality of charged bodies provided with different dry toners to one charged body, respectively. It is possible to overlay images.

  According to the present invention, the functional agent can be fixed only to a necessary portion regardless of the surface state of the substrate. For this reason, waste of the functional agent is suppressed.

First, image formation by the 4-toner image forming unit 15 will be described. The intermediate transfer belt 23 from which the deposits have been removed by the cleaning device 24 is subjected to charge removal processing by the charge removal device 25. Next, the intermediate transfer belt 23 that has been neutralized is conveyed to four image forming units 29 via a pulley 21.

  Each image forming unit 29 performs the following operations. First, the photosensitive belt 29k from which the deposits have been removed by the cleaning device 29a is subjected to charge removal processing by the charge removal device 29b, and is charged by the charging device 29c. The exposure device 29 applies a desired charge onto the photosensitive belt 29k. A charged image or latent image having an arbitrary shape is formed. Thereafter, dry toner containing a functional agent is electrostatically supplied onto the photosensitive belt 29k by the developing device 29e, whereby an image of toner particles is formed on the photosensitive belt 29k. Then, the image of toner particles on the photosensitive belt 29k is transferred onto the intermediate transfer roller 23 by the primary transfer roller 29p. Here, the toners provided by the developing device 29e of each image forming unit 29 can be made different from each other, and the latent images formed by the exposure device 27 can also be made different from each other.

At that time, as shown in FIG. 3, the secondary transfer roller 16 pushes up the substrate 14 and the conveyance belt 13 from below, and the intermediate transfer belt 23 removes the dry toner particles T on the intermediate transfer belt 23 from the upper surface of the substrate 14. The secondary transfer roller 16 is stopped at a position where the transfer gap G between the upper surface of the base material 14 and the dry toner particles T is not less than 0 mm. At such a position, the upper surface of the substrate 14 and the dry toner particles T on the intermediate transfer belt 23 are in a non-pressure contact state or a non-contact state with each other.

  The base material 14 onto which the image on the intermediate transfer belt 23 has been transferred is sent to the fixing device 17. As the fixing device 17, for example, a non-contact heater such as an infrared heater (preferably a far infrared heater) can be used.

  Thus, the fabric on which the image is fixed by the fixing device 17 is a base material on which the functional agent is fixed, and is also called a printed material.

  Subsequently, the base material 14 on which the image by the dry toner is fixed is peeled off from the conveying belt 13 by the peeling roller 18, and if necessary, the toner is more firmly fixed or a post process is performed.

Thereafter, one developing device 29e corresponding to the formed latent image of the four developing devices 29e is operated, and an image of toner particles corresponding to the latent image is formed on the photosensitive belt 23A.

  Next, the image formed by the developing device is transferred below the pulley 22A by the transfer electric field applied between the photosensitive belt 23A and the transfer belt 77A by the potential of the primary transfer roller 79A of the transfer unit 70A. Transcribed to the side. Through rotation of the pulleys 21A and 22A in the image forming unit 15A and the pulleys 71A, 73A, and 75A of the transfer unit 70A, the image formed on the photosensitive belt 23A is transferred to the transfer belt 77A side. Thereafter, the photosensitive belt 23A is freed of deposits by the cleaning device 24, and an image of other toner is formed by the developing device through charge removal, charging, and exposure, and transferred onto the transfer belt 77A.

  By repeating such transfer, image superposition with different toners is electrostatically provided on the transfer belt 77A.

(Fourth embodiment)
FIG. 6 is a schematic configuration diagram of a functional agent fixing device 200 according to another fourth embodiment of the present invention. In the functional agent fixing devices 100, 200, and 300, a method for forming an arbitrary image on a photosensitive belt or a transfer belt and transferring the image to a base material such as a fabric has been described. In the fourth embodiment, an arbitrary image is formed. However, the functional agent is fixed to the entire surface of the substrate such as a fabric, and this image is also called a solid image.

  In the present embodiment, an image forming unit 35 for supplying a solid image with a single functional agent-containing toner is provided instead of the four-toner image forming unit 15 in the functional agent fixing device 100 of FIG. The same components as the functional agent fixing device 100 are provided in the portions, and the corresponding components are denoted by the same reference numerals.

  The image forming unit 35 includes a metal toner transport drum 33 as a charging body, not a photoconductor. Therefore, even if the toner transport drum 33 is charged, the charge is uniformly distributed, so that a solid latent image is always formed. A power supply (not shown) for applying a voltage for carrying toner is connected to the toner transport drum 33. Further, the image forming unit 35 includes a toner applying device 38 for supplying toner to the toner transport drum 33. A transfer electrode 30 for controlling the toner transfer amount and a power source (not shown) for applying a transfer voltage to the transfer electrode 30 are disposed below the toner transport drum 33. The transfer electrode 30 is provided with an opening 31 for allowing dry toner to pass therethrough, and a secondary transfer roller 16 b is provided below the opening 31. The secondary transfer roller 16b is provided with a high voltage power source 2 and a transfer gap adjusting device 16a.

  A voltage is applied to the toner conveying drum 33 (500 to 1000 V), and the toner of the toner applying device 38 is charged with a polarity opposite to the voltage, so that the toner adheres to the surface of the toner conveying drum 33, The toner is transported to the opening 31 by the rotation of the toner transport drum 33. A voltage (1000 to 2000 V) having the same polarity as that of the toner conveying drum 33 is applied to the transfer roller 16b. When a control voltage is applied (500 to 1500 V) to the transfer electrode 30 under these conditions, the toner flies toward the base material 14 that is a recording medium. The amount of flying toner is controlled by the voltage of the transfer electrode 30, and the amount increases as the voltage increases. Thereafter, the toner on the base material 14 is fixed by the fixing device 17 as in the apparatus of FIG. 2, and becomes a base material on which the functional agent of the final product is fixed through a heating process performed with the prince as necessary. .

  Embodiments of the present invention are not limited to the above, and various modifications are possible.

  For example, the form of the electrostatic holding part is not limited to the above-described aspect. Further, the configuration of the transfer portion is not limited to the above, and any configuration may be used as long as the dry toner on the charged body can be ejected by an electric field with respect to the base material facing the charged body. Further, the configuration of the electric field application unit is not particularly limited as long as it can generate an electric field that allows toner particles to fly.

  Further, the configuration of the base material transport unit is not limited to the transport belt. Moreover, the aspect of a fixing | fixed part is not limited to the said embodiment, The press by a heating roll may be sufficient.

  In the first to third embodiments, four toners containing a functional agent are used. However, the present invention is not limited to this, and the number of toners is one, two, three, five or more. But you can.
