[0011] This invention relates to a 'method for manufacturing a non-toxic olefin advertising sheet that facilitates digital printing and recycling of advertisements and a non-toxic olefin advertising sheet using the same,' which has a composition that facilitates manufacturing, improves workability, and reduces manufacturing costs. Background Technology

[0012] Hereinafter, the technology constituting the background of the present invention will be described, and the technology constituting the background of the present invention is Described in detail in "Synthetic polymer-based roofing sheet with improved stain resistance and weather resistance and method for manufacturing the same," registered and published as Republic of Korea Patent Registration No. 10-0820597 (Registration Date: April 2, 2008). It is written, and citing this, the technology forming the background of the invention and additional problems of the prior art were described.

[0013] A photo-printed surface, which is an advertisement or placement printed by a photo-printing machine, is formed on the exterior of a tarpaulin, which is a fibrous substrate generally used as an advertising material, or:

[0014] Alternatively, a tarpaulin for photo printing in which a photo printing sheet, which is a printed sheet with the above-mentioned photo printed surface, is bonded and used is:

[0015] Tarpaulin, which is a substrate in which polyvinyl chloride (PVC) or polyethylene (PE) resin is impregnated on the exterior of fiber yarns, is primarily used. This is because when a real-image printed surface is printed on the exterior of the substrate impregnated with PVC or PE resin, the polarity, which is an inherent physical property of the resin, allows the image to be easily printed on the substrate.

[0016] As illustrated in Fig. 1;

[0017] The tarpaulin (300) used as an advertising material in the above-mentioned prior art is a tarpaulin that is a waterproof sheet in which vinyl chloride (PVC) resin or polyethylene (PE) resin (312) is impregnated into fiber yarns, and is used as a base material (310).

[0018] The above-mentioned material (310) is composed of a double-printed tarpaulin (300) having an advertising material, such as an advertising phrase or an advertising pattern, printed on the upper and lower parts of the material using a printing press (313, 314), respectively:

[0019] Alternatively, the tarpaulin (300) for printing with a double bonded structure is composed of printed sheets (315, 316) each having an advertising material, such as an advertising phrase or an advertising pattern, printed on the upper and lower parts of the above-mentioned material (310) as a printed sheet (313, 314), which are respectively laminated and bonded.

[0020] The above-mentioned multiple identical printed surfaces (313, 314) are each printed on the upper and lower parts of the substrate (310), or the above-mentioned printed sheets (315, 316) are each laminated and bonded in a double structure, and during the day, the content of the advertisement is clearly displayed to the outside by the above-mentioned multiple printed surfaces (313, 314), but

[0021] In the case of nighttime, the light source of the lighting fixture located on the rear of the above tarpaulin (300) is irradiated onto the plurality of real-image printed surfaces (313, 314) or the plurality of real-image printed sheets (315, 316), and the structure is configured such that the content of the advertisement is displayed to the outside, which causes problems such as reduced workability and increased costs;

[0022] In addition, in the case of tarpaulin made of polyethylene resin, due to the physical properties, the photoprint ink does not easily adhere to the substrate, making it difficult to form a photoprinted surface on the outside of the substrate.

[0023] Composed of simple polyethylene material without elastomer components, the product is hard due to its high hardness, resulting in problems such as reduced workability and decreased cold resistance, weather resistance, and durability;

[0024] Weather resistance is significantly reduced, rendering the printed surface unusable upon prolonged outdoor exposure as it disappears;

[0025] The current situation is that problems are arising where the durability of the finished product and processability during production are degraded due to reduced bonding strength and dimensional stability.

[0026] In particular, due to the nature of weaving, when the woven yarn has a wide or square width in the warp direction, denier deviations occur for each warp across a large number of warp threads. When this is woven and the fabric is wound, the accumulated error between warp threads causes areas with higher denier to protrude from the outside of the fabric during winding. Consequently, when digitally printing advertisements containing documents, images, or numbers on the outside of the fabric, the print clarity is significantly reduced.

[0027] The adhesion of the digital printing layer and the smoothness of the product surface are significantly reduced, making it difficult to use, and

[0028] In the case of tarpaulins made of vinyl chloride resin, environmental hormones, which are pollutants, were released, making them unsuitable for use as recycled raw materials after use, and

[0029] When disposed of, pollutants are emitted, causing environmental pollution problems, and the migration of plasticizers leads to printing defects or reduced weather resistance, resulting in product discoloration;

[0030] The current situation is that there are problems with reduced workability and excessive manufacturing costs, as the tarpaulin (300) for printing images has a double printing structure in which advertising materials, such as advertising text or advertising patterns, are printed on the printing surfaces (313, 314) of the printing machine.

[0031] Therefore, the yarn (YARN GRADE) is stretched to the maximum elongation rate, so that stretching or shrinking of the yarn is minimized;

[0032] A fabric with a flat surface is woven;

[0033] Digital printing of advertising content, including literature, figures, or numbers, is easy on the exterior of the substrate, and at the same time, the adhesion of the digital printing layer of the advertising content and the quality of the product surface are improved, so that the print clarity of the advertising content is even sharper;

[0034] It is 100% recyclable, made of non-toxic material, and is harmless to the human body;

[0035] There is an urgent need to develop a 'method for manufacturing non-toxic olefin advertising paper that facilitates digital printing and recycling of advertisements, and a non-toxic olefin advertising paper using the same,' which is easy to manufacture, improves workability, and reduces manufacturing costs. The problem to be solved

[0036] By the 'method for manufacturing a non-toxic olefin advertising leaflet that is easy to digitally print and recyclable, and a non-toxic olefin advertising leaflet using the same' of the present invention;

[0038] In particular, the woven yarn made of polypropylene or polyethylene is stretched to the maximum elongation rate so that stretching or shrinking of the yarn is minimized;

[0039] A fabric with an overall flat surface is woven by feeding the yarn in the warp direction with a width smaller than the standard yarn width;

[0040] By means of a substrate coated with a modified olefin resin capable of digital printing on the outside of a fabric with a flat surface, an advertisement including literature, pictures, or numbers is digitally printed on the outside of the substrate, thereby facilitating the digital printing of the advertisement, while simultaneously improving the adhesion of the digital printing layer of the advertisement and the quality of the product surface, so that the print clarity of the advertisement is even sharper;

[0041] It is 100% recyclable, made of non-toxic material, and is harmless to the human body;

[0042] The purpose of the present invention and the problem to be solved by the present invention is to provide a 'method for manufacturing a non-toxic olefin advertising sheet that is easy to digitally print and recycle advertising materials and a non-toxic olefin advertising sheet using the same' with a composition that is easy to manufacture, improves workability, and reduces manufacturing costs. means of solving the problem

[0142] The entire product is 100% recyclable and is made of non-toxic material, proving to be harmless to the human body.

[0143] In addition, the printed installation of a commercial shooting range, which is Comparative Example 1, is a conventional silica fabric coated with flame-retardant silicone:

[0144] It was found that printability was partially degraded, causing the digital printing layer to partially peel off during UV digital printing, resulting in usability issues and a faintly printed layer;

[0154] Comparative Example 1 was found to have no pollutants generated by coating a silica substrate and silicon, but compared to Example 1, the actual image printed surface was laminated and bonded in a double structure on the upper and lower parts of the substrate, resulting in increased costs and reduced workability during manufacturing;

[0155] Comparative Examples 2 and 3 were unusable as recycled raw materials after use because environmental hormones, which are pollutants, were emitted due to the coating of PVC resin (vinyl chloride resin) on the upper and lower surfaces of the substrate, and environmental pollution problems arose due to the emission of pollutants upon disposal:

[0156] Compared to Example 1, the structure in which the actual printing surface is laminated and bonded in a double structure on the upper and lower parts of the substrate, respectively, was found to increase the cost and significantly reduce workability during manufacturing.

[0157] Although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications can be made by those skilled in the art within the scope of the technical concept of the present invention;

[0158] Furthermore, an advertising sheet digitally printed with an advertising publication including literature, figures, or numbers applied in the present invention is one preferred embodiment, and it is obvious that it can be applied to other materials within the same technical category of the present invention.
