DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(11) For better understanding of present invention, I provide the embodiment and drawing enclosed for detailed description. Those who skilled in the art can understand purpose, the feature and benefit of the present invention from the contents disclosed in this specification. Kindly noted that the present invention can be implemented or applied through other different specific embodiments and based on different viewpoints various details in this specification can be various changed without departing from the spirit of the present invention. In addition, the drawings attached to the present invention are merely a schematic illustration and they are not depicted in actual dimensions. The following embodiments will further describe the related technical content of the present invention in detail, but the disclosed content is not intended to limit the technical scope of the present invention.

(12) Referring to FIGS. 2-8, the splicable environmentally-friendly non-PVC advertising cloth made of a woven structure on the applicable embodiment, wherein the advertising cloth comprising multiple layers structure below: a mesh base layer (40), which is a knitted fabric made of warp threads (41) and weft threads (42), as FIG. 5 showing, the warp threads (41) and the weft threads (42) are made of polyester fiber, and wherein the mesh base layer (40) has high density meshes (45) and tensile strength, and wherein the mesh base layer (40) further has a front surface (43) and a rear surface (44).

(13) A first adhesion-promoting structural layer (10), which is a fireproof and waterproof layer having a fireproof and waterproof material (11) and an adhesive (12) coated on the mesh base layer (40) for the slurry penetrating the meshes (45) and covering the front surface (43) and the rear surface (44) of the mesh base layer (40) to form a first surface (13) formed on the front surface (43) and a second surface (14) formed on the rear surface (44), so that the first adhesion-promoting structural layer (10) and the mesh base layer (40) are firmly bonded. In this embodiment, the fireproof material can be a fluoride-free phosphate ester fire retardant and the waterproof material can be a fluoride-free waterproof agent, but is not limited; the adhesive (12) can be an epoxy resin adhesive, a polyurethane adhesive, a polyvinyl acetate adhesive, etc., but is not limited. The composition of these materials belongs to the prior art and is not the subject of the present invention. Therefore, their details are not discussed here.

(14) A second adhesion-promoting structural layer (20), which is an ink-absorbing layer, the second structural layer has an acrylic resin which is the main component (21) and an adhesive (22) coated on the first surface (13) of the first adhesion-promoting structure layer (10), resulting in a bottom surface (23) formed on the first surface (13) of the first adhesion-promoting structure layer (10) and an upper surface (24) formed on the opposite side, so that the second adhesion-promoting structural layer (20) and the first adhesion-promoting structure layer (10) are firmly bonded. The composition of these adhesives belongs to the prior art and is not the subject of the present invention.

(15) A third adhesion-promoting structural layer (30), which is an advertising ink layer, the third structural layer has an advertising ink which is the main component (31) and an adhesive (32) coated on the upper surface (24) of the second adhesion-promoting structure layer (20). In this embodiment, the adhesive (32) can be a silicon dioxide. Silicon dioxide is a colorless crystal or white powder, with the exception of hydrofluoric acid, the silicon dioxide is insoluble in water and acids, can be spliced with most metal oxides, is non-flammable, has a high dielectric constant and is highly resistant to heat and impacts. Therefore, the addition of silicon dioxide to the advertising paint can also increase the fire resistance and shrinkage of the advertising paint layer further improving the adhesion-promoting structure.

(16) The advertising cloth (50) has the below features: a mesh base layer (40) with a refractory, waterproof and ink absorbing layer, in addition to the mesh base layer 40, additional adhesives are added to the first and second structural layers and silica is added to the third layer. In this way, the main structure of the advertising cloth (50) of the present invention is the mesh base layer (40) comprising the refractory and waterproof layer with the first adhesion-promoting structure layer (10), the ink-absorbing layer with the second adhesion-promoting structure layer (20); and the advertising ink layer with the third adhesion-promoting structure layer (30). Accordingly, the advertising cloth (50) forms a composite structure with the refractory, waterproof and ink-absorbing layer on the mesh base layer (40) and also has a splicable adhesion-promoting structural layer.

(17) According to the principle of glued adsorption: the main source of bonding force is the molecular force of the bonding system, namely Van der Waals force and hydrogen bonding force. The adhesion and adsorption force between the glue and the surface of the adherend have the same properties. There are two processes of action of the adhesive molecules and the surface molecules of the adherend: the first stage is that the liquid adhesive molecules diffuse to the surface of the adherend by means of Brownian motion, so that the polar groups or chain links on the two interfaces are close to each other; in this process, heating up, applying contact pressure and reducing adhesive viscosity are all conducive to the strengthening of Brownian motion. The second stage is the generation of adsorption force. When the distance between the adhesive and the adherend molecules reaches a predetermined value, the interface molecules generate mutual attraction, which further shortens the distance between the molecules to a maximum stable state. Furthermore, the main structure of the advertising cloth (50) of the present invention comprises: the refractory and waterproof layer with the first adhesion-promoting structure layer (10); the ink-absorbing layer with the second adhesion-promoting structure layer (20); and the advertising ink layer with the third adhesion-promoting structure layer (30). In this way, the advertising cloth (50) forms a composite structure with the refractory, waterproof and ink-absorbing layer on the mesh base layer (40).

(18) According to the principle of glued adsorption mentioned above, the advertising cloth (50) also has a splicable adhesion-promoting structural layer. Since the advertising cloth (50) of the present invention improves the adhesion-imparting structural layer, it can be further spliced by using a high-frequency processing method. The conventional wall cloth had no adhesion-promoting structural layer, so that it could not be spliced by using processing methods such as high frequency and could only be processed by “sewing”. Also, the general flatness and quality of the wall cloth that was processed by the “sewing” process is not as good as that of the high-frequency splicing process.

(19) As shown in FIGS. 2 and 3, when splicing the two advertising cloth (50a, 50b) the present invention melts the adhesion-promoting structural layers (10, 20, 30) with high frequency for superimposing splicing surfaces (51); and the interface molecules are attracted to one another, so that the two advertising cloth (50a, 50b) are very stably connected to one another after the splicing, as FIGS. 6A and 6B showing.

(20) The PET fiber mesh base layer (40) used in the advertising cloth (50) of the present invention has high-density meshes (45) and high tensile strength. The polyacrylic resin in the refractory and waterproof adhesive layer of the first adhesion-promoting structural layer (10) is a non-toxic, odorless, tasteless and milk-white highly crystalline polymer, with a density of only 0.90 to 0.91 g/cm3, the polyacrylic resin is one of the lightest plastics, which is about 60% corresponds to the density of PVC. Among the general-purpose plastics, polyacrylics have the best heat resistance with a heat resistance of 80 to 100° C., nice resistance to stress cracks and a long flex fatigue life. In addition, the ink-absorbing layer of the second adhesion-promoting structural layer (20) is mainly made of acrylic resin and has an ink-absorbing property with a suitable ratio of the polyacrylic resin.

(21) Therefore, the advertising cloth (50) arranged on the mesh base layer (40) forms a composite structure with a refractory, waterproof and ink-absorbing layer.

(22) The present invention has the following features and effects that need to be clarified:

(23) 1. The environmentally friendly advertising cloth (50) of the present invention has been sent to the CSI Italy Laboratory, a facility certified by the European Union, for testing. The test results have reached the fire protection level “Class B” in the European standard for fire protection standards EN13501-1-B-s1-d0, and about the combustion performance of the product, wherein the additional level of smoke development is: “s1”. The additional level of burning drops/particles is: “d0”. Therefore, the environmentally friendly advertising cloth (50) of the present invention fits the European Union standards for higher fire safety, so that there is no doubt about its flame retardancy and fire resistance.

(24) 2. The environmentally friendly advertising cloth (50) of the present invention can achieve the waterproof function and has the properties of being cleanable and does not have the disadvantage of shrinking that the conventional PVC advertising cloth has.

(25) 3. The structure of the advertising cloth (50) of the present invention contains no PVC and is non-toxic, so that it is particularly suitable for indoor advertising and interior decoration and fulfills the use for medical purposes.

(26) 4. Compared to the conventional PVC advertising cloth in the current market, the structure of the advertising cloth (50) has a weight reduction of almost 35%, so that it is light and soft, and it is easy to be attached and removed. FIG. 7 shows an illustration the splicing of the advertising cloth of the present invention when advertising pattern is printed on each of the advertising cloth (50a), (50b), (50c), etc. before splicing. The maximum width (Wmax) of each advertising cloth (50a), (50b), (50c . . . ) is limited by the existing technology and machine and can only reach a width of approximately 5 meters. However, the present invention can splice the printed advertising cloth (50a), (50b), (50c) with high-frequency processing methods. In this way, the width (W) of the advertising pattern can be unlimited (Wmax1+Wmax2+Wmax3+ . . . W∞).

(27) Moreover, as FIG. 7 showing, the advertising cloth (50) of the present invention has nice structure strength and can be processed with a predetermined molding machine to make the width (W) of the advertising cloth (50) to be adjusted according to the customer's requirements. The length (L2) of the advertising cloth (50) after molding is exceedingly long, but it can be rolled up. So, when we are producing advertise (A), no matter how the height (H2) it is, it can be cut by requirements. Furthermore, the maximum width (Wmax1+Wmax2+Wmax3+ . . . W∞) of the advertising cloth (50) by splicing variety of advertising cloth (50a+50b+50c+ . . . ) can be unlimited. Therefore, the size of the printed image will not be limited. Therefore, the environmentally friendly advertising cloth (50) of the present invention has greater applicability and selectivity.

(28) In addition, the advertising cloth (50) of the present invention also fulfills the environmental protection requirements. The following table is the test report on the biodegradability of the advertising cloth (50) of the present invention.

(29) Report No. SCTF-A20170503-005N

(30) TABLE-US-00001 Test No. Test Item Data Remark 1 Percentage of biodegradability 23.5 Reference ratio 45 days of degradation ) % (cellulose): 71.5% Note Description of the sample: The sample is a white wall cloth with an organic carbon content of 43.88%. Reference material is thin layer chromatography cellulose, white powder with particle size 20 μm, organic carbon content 43, 90%; Others: The composting method is using the vermiculite method,: after the compost-specific bacteria have been activated, they are vaccinated in vermiculite and activated for 96 hours.

(31) The test spectrum of the advertising cloth (50) of the present invention, the biodegradation curve of the compost test, is shown in FIG. 8.

(32) From the above test report, we can know that the advertising cloth (50) of the present invention is degradable and, in the event of a landfill decomposition, does not produce any other toxic substances which contaminate the soil and water.

(33) Based on the above description, the comparison between the advertising cloth of the present invention and the conventional advertising cloth are shown below:

(34) TABLE-US-00002 Present invention Prior art Conventional PVC Weight 110 gsm~370 gsm 110 gsm~370 gsm 220 gsm~900 gsm coating PA PA PVC material secondary water-based raw water-based raw plasticizer material materials materials odor no pungent smell no pungent smell pungent chemical smell harmless REACH168, 33P, REACH168, 33P, REACH168, 6P for human Oeko-tex Oeko-tex body standard 100 standard 100 refractory meet Up to M1 meet Up to M1 meet Up to M1 standards Refractory EN13501-1 EN13501-1 — test Applicable UV, Latex, Dye sub UV, Latex, Dye sub Sol, eco-sol, Latex, dye type UV, Screen useful life longer than one longer than one ideally 6 months, year because there year because there usually 6-12 months is no plasticizer is no plasticizer Recycling Landfill or Landfill or Landfill or process incineration does incineration does incineration will not cause any major not cause any major cause huge pollution pollution and can be pollution and can be and hard to be recycled recycled recycled Heat −40□~90□ −40□~90□ −30□~70□ tolerance Increasing Having Cannot increase the using high frequency the width adhesion-promoting width by splicing, splicing to increase structural layer, only can use sewing the PVC width using high frequency to increase width splicing to increase the width

(35) From the table above, we can tell that although the conventional PVC advertising cloth can be spliced by using high frequency to increase the width of the PVC advertising cloth. However, the advertising cloth (50) of the present invention has the features of refractory, waterproof and ink absorption, easily cleaned, easily removed, not allergy-causing and not toxic. Compared to the prior art wall cloth which cannot be spliced by using high frequency, the advertising cloth of the present invention can be printed with any image and can be spliced to reach the required width. In addition, the width of the advertising cloth of present invention (50a+50b+50c . . . ) can be spliced by using high frequency process, whereby can increase the width unlimitedly. Therefore, the advertising cloth (50) of the present invention can avoid the defect in prior art wall cloth which cannot be spliced by high frequency, and further ensures increased applicability and selectivity.

(36) Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
