Description

  The present invention relates to a non-woven fabric substrate, and a printed matter that can be suitably used as a marathon bib, etc., which includes optically read information or information visually identified in addition to the non-woven fabric substrate.

In recent years, citizen marathon competitions and ski competitions have flourished due to health booms, and many citizens participate. In such competitions, bib numbers specifying the competition name and competitor number are distributed to the participants and worn on the day of the competition, but the competitor number is different for each bib number, so the bib number printed on the competition name is unique. The actual situation is that each player's number is printed manually, resulting in problems of workload and cost increase. Furthermore, in recent years, there has been a demand for registering participants' blood types, medical history, etc. in advance so that they can respond quickly when they encounter an injury or accident during the competition. However, with the recent increase in interest in handling personal information, such information is incorporated into each number so that such personal information can be quickly retrieved when necessary without being easily leaked to others. It is thought that it is ideal, but such a means has not been solved yet.
Furthermore, for participants who are blind, it is also requested to provide Braille in the bib, but the technology that can easily and quickly produce the bib having information that is identified by tactile sense such as Braille is still not available. Not developed.

  Inkjet, on the other hand, is a technology that forms an image by flying ink onto an object based on digital data, and is widely used in publications and posters because it has advantages such as high speed, multiple colors, and low noise. Yes. Inkjet image formation does not require the preparation of a plate like offset printing, and does not require heat-fixing processing such as electrophotography used in copiers and laser printers. The mechanism is also simple. In conventional offset printing, information common to all printed materials is printed first, and then different information is printed on each printed material one by one manually. On the other hand, there is an advantage that it is possible to simultaneously print both information common to all printed matter and information different from each other by printing by the ink jet method.

Paper is generally used as a base material for printed matter on which an image is formed by the inkjet method. However, when the printed matter is used under relatively severe conditions, for example, when the printed matter is used outdoors. It is necessary to use a substrate having weather resistance against wind and rain and light. As such a base material, a nonwoven fabric having features such as light weight and flexibility has been proposed (for example, Patent Document 1).
On the other hand, by providing the printed matter with optical reading information such as two-dimensional code such as barcode, QR code, Data Matrix, PDF417, Maxi Code, Veri Code, etc., information that is preferably read by optical means is encoded. It is also known that each printed matter can be identified.

Patent Document 2 discloses a brand identification method characterized by using a magnetic ink and identifying a regular brand and a counterfeit brand by applying an embroidery or a woven name with a brand name mark such as a character, a figure, or a symbol. Although it discloses, the printed matter provided with the optical reading information formed by printing on a nonwoven fabric base material using an inkjet system is not disclosed.
In Patent Document 3, a basic process in ink-jet dyeing with an ink mainly composed of a dye for recording information such as characters, images, or identification marks on a cloth, that is, (1) a blur prevention process is performed on the cloth. (2) Dye a dye that forms a temporary image with ink mainly composed of a dye by using an ink jet printer or the like by penetrating and diffusing into the fiber of the fabric. (3) A dye that forms a temporary image by heat treatment or the like is permeated and diffused in the fibers of the fabric to be dyed. (4) During the process of removing excess dye by reduction washing or the like, the object is to solve various problems in the heat treatment of (3). That is, Patent Document 3 discloses various problems in the heat treatment of (3) above by temporarily displaying characters, images, or images such as identification marks on the woven fabric, knitted fabric, or non-woven fabric (A) with ink mainly composed of dye. After forming, at least an image forming surface of the woven fabric, knitted fabric or nonwoven fabric (A) is overlapped with the woven fabric, knitted fabric, nonwoven fabric or paper (B), and the dye for forming the temporary image by heat treatment is added to the woven fabric, knitted fabric or nonwoven fabric. Disclosed is a method for producing an information fabric characterized in that it is infiltrated, diffused and dyed in the fibers constituting (A). However, as described above, printing with an ink mainly composed of a dye employed in the method for manufacturing an information fabric disclosed in Patent Document 3 requires a plurality of complicated steps, and is associated with cost and many technical disadvantages. In addition, the dye ink method in which the waste liquid flows out after the heat treatment with a cleaning process is disadvantageous from the viewpoint of environmental protection.

  So far, it has been useful for bibs used in citizen marathon competitions, etc., and has information common to each bib such as the competition name, etc., and different information for each bib such as the athlete number, etc. No technology has yet been developed that can easily and efficiently print personal information of a person on a sheet of bib.

Since the ultraviolet curable ink composition used in the present invention is of an ultraviolet curable type, it is preferable that it does not contain a solvent so that it can quickly react and be cured immediately after landing of the ink composition. However, a predetermined solvent can be included as long as the curing rate of the ink composition is not affected. As the solvent, an organic solvent or water can be used. In particular, the organic solvent can be added in order to improve the adhesion with the recording medium (support such as nonwoven fabric and paper).
The amount of the organic solvent is, for example, in the range of 0.1% by mass to 5% by mass, preferably 0.1% by mass to 3% by mass with respect to the total mass of the ultraviolet curable ink composition used in the present invention.
