[0045] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0046] like Figure 1 As shown, a paper mat (hereinafter simply referred to as “mat”) 1 according to an embodiment of the present invention includes a base fabric 11 and a pile material 12 . Figure 1 The outer shape of the pile material 12 is schematically shown by a two-dot chain line.

[0047] In this embodiment, the mat 1 is an artificial turf paving body laid on the ground. By covering the entire ground or a part of the ground with the mat 1, an artificial turf can be formed. The ground as the object can be any ground outdoors or indoors.

[0048] The base fabric 11 fixes piles 121 for forming a lawn. The base fabric 11 is formed to have predetermined vertical and horizontal dimensions so as to extend in the longitudinal and lateral directions of the mat 1, that is, in the planar directions parallel to the ground or floor surface on which the mat 1 is installed. Figure 1 The longitudinal direction of the bedding material 1 is represented as the Y direction, and the transverse direction is represented as the X direction. The Z direction is the vertically upward direction, that is, the upward direction. The base fabric 11 can be formed of a suitable synthetic resin material such as polyester or polypropylene, and can be a non-woven fabric or a woven fabric formed by flat weaving yarns (yarns) made of synthetic resin.

[0049] The pile material 12 is provided so as to cover the entire surface side of the base fabric 11. The pile material 12 includes a large number of piles 121 formed of pulp, and these large number of piles 121 are implanted in the base fabric 11 at a density that restricts the inflow of air into the interior of the pile material 12, in other words, into the gaps between the piles 121 or Japanese paper yarns 1211 constituting the pile material 12. Here, the pile material 12 refers to a collection of a plurality of or a large number of piles 121.

[0050] In the present embodiment, each pile 121 is formed by twisting a plurality of Japanese paper yarns 1211. That is, the pile 121 is in the form of a twisted yarn. The Japanese paper yarns 1211 constituting the pile 121 are also called shosenshi, which are shosenshi yarns (Shosenshi) and are shosenshi yarns (Shosenshi) shosenshi yarns (Shosenshi) shosenshi yarns 121 ... + "For commercial use. The Japanese paper yarn 1211 is colored to a color similar to lawn (e.g., green).

[0051] As shown in the enlarged cross-sectional view of the bedding material 1 Figure 2 and Figure 3 As shown, the piles 121 are arranged in a row along the longitudinal direction (Y direction) ( Figure 3 ), the same multiple columns are arranged at a certain interval in the horizontal direction (X direction) ( Figure 2 ). Moreover, the root portion 121a of each pile 121 penetrates the base fabric 11 from the front side to the back side, and is fixed to the base fabric 11 by the resin coating 13 formed on the back side of the base fabric 11 by coating.

[0052] As described above, each pile 121 is formed by twisting a plurality of Japanese paper yarns 1211. In the present embodiment, one pile 121 is formed by twisting four Japanese paper yarns 1211. Here, the pile 121 is freed from the constraint of twisting at the front end portion opposite to the root portion 121a fixed to the base fabric 11, and is in a state of being untied into individual (i.e., four) Japanese paper yarns 1211. Each Japanese paper yarn 1211 simulates a lawn. The number of Japanese paper yarns 1211 twisted may be an appropriate number other than four, such as two.

[0053] The density of the pile 121 is set to a density of 10 or more piles 121 per square inch of the base fabric 11 in the longitudinal and transverse directions, respectively. In the present embodiment, the density is set to 14.9 or more piles in the longitudinal direction, i.e., the Y direction, and 10 or more piles in the transverse direction, i.e., the X direction. Here, the number of piles 121 per square unit may be the same in the longitudinal direction and the transverse direction, or may be different. Furthermore, the height dimension of the portion of the pile 121 protruding upward from the base fabric 11, i.e., the length L, is set to 10 mm.

[0054] Hereinafter, a method for manufacturing the mat 1 according to the present embodiment will be described.

[0055] exist Figure 4 In the flowchart shown, in the pulp production step shown in S101, Manila hemp pulp or wood pulp is steamed to produce pulp.

[0056] In the papermaking step shown in S102, papermaking is performed using the pulp produced in S101 to produce base paper P of Japanese paper yarn. A dyeing step of coloring the base paper P is performed along with the papermaking step.

[0057] In the slitting process shown in S103, the base paper P manufactured in S102 is cut into a predetermined width W to produce a strip TP of Japanese paper. Figure 5 As shown in (a) of FIG. 1 , while the base paper P is moved in the conveying direction indicated by the arrow, the slitting knife C1 is brought into contact with the base paper P to cut the base paper P into a width W of 1 mm to 4 mm. Thus, a strip TP having a width W is produced.

[0058] In the twisting process shown in S104, the strip TP produced in S103 is twisted to produce Japanese paper yarn TH. Then, a predetermined number (four in this embodiment) of Japanese paper yarns TH are twisted together to form Japanese paper twisted yarns, that is, piles 121. The piles 121 are stored in a state of being wound on a creel. Figure 5 (b) shows the process of twisting the strip TP to produce the Japanese paper yarn TH, Figure 5 (c) shows a step of twisting four Japanese paper yarns TH to form the pile 121.

[0059] In the knitting step shown in S105 , the piles 121 produced in S104 are tufted by a tufting machine, thereby producing the paper fabric 1 having the piles 121 planted on the surface side of the base fabric 11 .

[0060] Specifically, if Figure 6 As shown in (a), the pile 121 is woven into the base fabric 11 that is transported in the direction indicated by the arrow (unidirectional arrow) in the same manner as that of weaving a carpet. The pile 121 is inserted into the base fabric 11 by a needle N that reciprocates in a direction perpendicular to the back side 11b of the base fabric 11 so as to pass through the back side 11b of the base fabric 11 toward the surface 11a, and the pile 121 is fixed in the inserted position by a retainer K that reciprocates in a direction parallel to the surface 11a of the base fabric 11. After being fixed by the retainer K, the needle N is pulled out and the retainer K is retracted to its original position. Thereafter, as shown in FIG. Figure 6 As shown in (b), the loop portion 121b at the front end of the pile 121 is cut off by a cutter or a hook-shaped knife C2, so that the front end of the pile 121 is released and the pile 121 is untied into individual Japanese paper yarns 1211. Thus, the planting of two piles 121 is completed.

[0061] In the backing process shown in S106, a backing treatment is applied to the back side of the base fabric 11. Specifically, a suitable synthetic resin material such as styrene-butadiene rubber (SBR) or nitrile-butadiene rubber (NBR) is applied to the back side of the base fabric 11, and the resin material is dried using a dryer called a tenter to form a resin coating. In this way, the pile 121 is fixed to the base fabric 11 to prevent the pile 121 from falling off the base fabric 11.

[0062] As described above, according to the present embodiment, since the pile 121 constituting the pile material 12 is formed of pulp (paper), biodegradability is excellent, and generation of harmful substances due to incineration is suppressed, it is possible to provide the mat 1 having excellent environmental characteristics.

[0063] Specifically, from the pile 121 or Japanese paper yarn 1211 of the fabric 1 of the present embodiment, for 8 heavy metals (antimony Sb, arsenic As, barium Ba, cadmium Cd, chromium Cr, lead Pb, mercury Hg, and selenium Se), the detection values ​​obtained by the test specified in the Japanese Industrial Standard JISL 1030 are all less than the detection limit (antimony Sb, arsenic As, barium Ba, cadmium Cd, chromium Cr, lead Pb, mercury Hg, and selenium Se: for Sb, As, Cd, Cr, and Hg, the detection limit is 5 mg / kg, and for Ba, Pb, and Se, the detection limit is 10 mg / kg), and a result of no detection is obtained, and a result of no detection is also obtained for formaldehyde (the detection value of free formaldehyde based on the harmful substance testing method specified in the Ministry of Health, Labor and Welfare Ordinance No. 34 is less than 20 μg per 1g), which can realize a bedding material 1 with extremely low harm to humans and high safety. Furthermore, the antibacterial activity value obtained by the bacterial liquid absorption method specified in JISL 1902:2015 was 2.3, which confirmed that it had antibacterial properties.

[0064] Furthermore, since the pile 121 is planted at a density that restricts the inflow of air into the pile material 12, it is possible to provide a matting material that uses pulp (paper) and has excellent fireproofing properties.

[0065] Here, the density of the embedded pile 121 is more than 10 in the longitudinal and transverse directions per 1 square inch of the base cloth 11, specifically, more than 14.9 in the longitudinal direction and more than 10 in the transverse direction, thereby being able to effectively limit the inflow of air into the interior of the pile material 12, improve flame retardancy, and achieve improved fireproof performance.

[0066] The bedding materials of Example 1, Comparative Example 1 and Comparative Example 2 shown below were subjected to the fire resistance test certified by the Japan Fire Protection Association. Only Example 1 passed the test, while the other Comparative Examples 1 and 2 failed. Compared with Example 1, Comparative Example 1 is different in that the density of the pile is low and flat cutting is not performed, so the pile with a loop portion remains. On the other hand, although the Comparative Example 2 is flat cut, the difference is that the density of the pile is low and the weight of the pile per square unit (i.e., the weight per unit area of ​​the fabric) is small.

[0067] (1) Embodiment 1

[0068] Using a 1 / 10G tufting machine (tufting instrument), the number of piles per square inch is 14.9 vertically and 10 horizontally. The loop part at the front end of the pile is cut off by flat cutting to obtain a bedding material with a pile length of 10 mm and a pile weight of 1230 g per square meter.

[0069] (2) Comparative Example 1

[0070] A 5 / 32G tufting machine was used to tuft 9.6 piles per square inch in the longitudinal direction and 6.4 piles per square inch in the transverse direction to obtain a High Cut Low Loop (1:1) bedding material with a pile length of 14 mm or 5 mm and a pile weight of 812 g per square meter.

[0071] (3) Comparative Example 2

[0072] Using a 5 / 32G tufting machine, the number of piles per square inch is 11 in the longitudinal direction and 6.4 in the transverse direction. The loop part at the front end of the pile is cut off by flat cutting to obtain a bedding material with a pile length of 10 mm and a pile weight of 1100 g per square meter.

[0073] In addition, according to the present embodiment, the pile 121 is made of paper, and the air permeability of the pile material 12 is also good, so it is not easy to get stuffy, and the rise in surface temperature due to heating by sunlight is suppressed, so comfort can be ensured even when used outdoors in summer.

[0074] The mat 1 of the present embodiment (hereinafter referred to as "paper artificial turf"), the artificial turf with pile formed of nylon (hereinafter referred to as "nylon artificial turf"), and the artificial turf with pile formed of polyester (hereinafter referred to as "polyester artificial turf") are respectively Figure 7 The test apparatus shown implements the surface temperature measurement test.

[0075] The paper artificial turf SPL1, nylon artificial turf SPL2 and polyester artificial turf SPL3 are placed on a sample stand 301 made of expanded polystyrene with their surfaces facing upward and their backs facing downward, and the surfaces of the artificial turf samples are irradiated with artificial sunlight for a predetermined time using an artificial solar lighting lamp (manufactured by SER IC Co., Ltd., artificial solar lighting lamp XC-500EFSS, hereinafter referred to as "lighting lamp") 201 set at a predetermined height H from the upper surface of the sample stand 301. The height H is, for example, 50 cm.

[0076] Then, after the irradiation of the lighting lamp is started, the surface temperature of the artificial turf samples SPL1, SPL2, and SPL3 is measured over time using a thermal imaging camera (InfReC R550 manufactured by AVIONICS Co., Ltd., Japan, with the emissivity set to 1.0) 202. The irradiation is performed multiple times (four times in this embodiment), and the positions of the artificial turf samples SPL1, SPL2, and SPL3 are interchanged during each irradiation. Figure 8As shown, the irradiation range R of the artificial sunlight of the lighting lamp 201 is divided into four parts, the upper left quadrant in the figure is the first area Rq1, and the quadrants arranged clockwise from the first area Rq1 are the second area Rq2, the third area Rq3, and the fourth area Rq4. Figure 8 , reference numerals SPLa, SPLb, SPLc, and SPLd represent artificial turf samples arranged in four quadrants Rq1 to Rq4, respectively. The center (i.e., the intersection of two axes dividing each quadrant) C of the artificial turf samples SPLa, SPLb, SPLc, and SPLd arranged in each quadrant Rq1 to Rq4 coincides with the center of the lighting lamp 201.

[0077] In the first irradiation, nylon artificial turf SPL2 is arranged in the first region Rq1, polyester artificial turf SPL3 is arranged in the second region Rq2, and paper artificial turf SPL1 is arranged in the third region Rq3. No artificial turf sample is arranged in the remaining fourth region Rq4, and the upper surface of the sample stand 301 is exposed. In the second irradiation, nylon artificial turf SPL2 is arranged in the second region Rq2, polyester artificial turf SPL3 is arranged in the third region Rq3, and paper artificial turf SPL1 is arranged in the fourth region Rq4. Similarly to the above, no artificial turf sample is arranged in the remaining first region Rq4, and the upper surface of the sample stand 301 is exposed. In this way, each time the artificial turf samples SPL1, SPL2, and SPL3 arranged in each region Rq1 to Rq4 are replaced, and the surface temperatures Tsp l measured for each artificial turf sample SPL1, SPL2, and SPL3 are averaged, and the average value is used as the test result.

[0078] Fig. 9 The graph shows the change of the surface temperature Tsp l of each artificial turf sample SPL1, SPL2, and SPL3 obtained as a result of the test over time. The horizontal axis shows the elapsed time t from the start of irradiation, and the vertical axis shows the surface temperature Tsp l of the artificial turf sample. The thick solid line shows the surface temperature Tsp l 1 of the paper artificial turf SPL1, the dot-dash line shows the surface temperature Tsp l 2 of the nylon artificial turf SPL2, and the double-dash line shows the surface temperature Tsp l 3 of the polyester artificial turf SPL3. The temperature of the test room is 20±2°C.

[0079] like Fig. 9As shown, for any of the artificial turf samples SPL1, SPL2, and SPL3, the surface temperature Tsp l tends to increase with the passage of time t, and it can be considered that there is a significant difference in the surface temperature Tsp l between the paper artificial turf SPL1 and the other artificial turf samples SPL2 and SPL3. In addition, it can be seen that the difference has a tendency to expand with the passage of time t. At time t1 (for example, 30 minutes after the start of irradiation), the surface temperature Tsp l 1 of the paper artificial turf SPL1 is 55.7°C, the surface temperature Tsp l 2 of the nylon artificial turf SPL2 is 71.6°C, and the surface temperature Tsp l 3 of the polyester artificial turf SPL3 is 70.2°C.

[0080] Since the surface temperature of natural turf under sunlight is about 50°C, it is found that the mat 1 according to this embodiment has a significantly suppressed increase in surface temperature Tsp l 1 compared to artificial turf samples SPL2 and SPL3 formed of synthetic resin materials, and can provide a usage environment close to that of natural turf.

[0081] In this case, as described above, the surface temperature Tsp l 2 of the nylon artificial turf SPL2 is 71.6°C, and the surface temperature Tsp l 3 of the polyester artificial turf SPL3 is 70.2°C. Therefore, the temperature rises to a level where, for example, the user cannot walk barefoot on the nylon artificial turf SPL2 or the polyester artificial turf SPL3 at this surface temperature. Even if shoes are worn, it can be predicted that the temperature of the user's feet will be greatly affected and the heat reflection will have a thermal effect on the entire body.

[0082] In contrast, with the paper artificial turf SPL1 of the present embodiment, the temperature rise is the same as that of natural turf even under the same ambient temperature conditions, so the user can walk barefoot, and the thermal effects on the feet when walking or running in shoes and the thermal effects on the entire body are suppressed to a greater extent compared to polyester artificial turf and nylon artificial turf.

[0083] In this embodiment, the case where the bedding material 1 is an artificial turf paving body laid on the ground is described. After the pile 121 is planted on the base fabric 11, the loop portion at the front end thereof is cut off, and the pile 121 is cut into an open end face state, thereby providing an artificial turf paving body with good water supply, drying and drainage properties and good air permeability. The bedding material 1 is not limited to an artificial turf paving body, and can also be a floor mat used indoors. In this case, not only can the loop portion 121b at the front end of the pile 121 be cut off to form a cut pile, but the loop portion 121b can also be retained without being cut off to form the pile material 12 as a loop pile.
