Conventionally known fluorescent carpets and fluorescent flooring materials have evacuation guidance signs or the like exposed by phosphorescent pigments exposed on the surface, which is obstructive in a bright normal state and impairs the appearance of the floor surface.
And even if the evacuation guidance sign exposed on the surface of the fluorescent carpet or fluorescent flooring is coated and protected by the coating film of the temporary transparent resin, the coating film to protect the coating itself is easily rubbed against the shoe sole. In particular, fluorescent carpets are easy to peel off because they are only attached to the tip of each pile fiber.

  Therefore, the present invention is not visible in a bright normal state, such as an evacuation guide sign using a phosphorescent pigment, and can only be seen after emitting fluorescence in the darkness in the event of a power outage. There is nothing, and it has both decorative properties as interior materials and wear resistance as floor materials, and is suitable for transportation materials such as aircraft, ships, automobiles, trains, etc., especially for aircraft interior materials that require emergency evacuation guidance signs The purpose is to obtain a fluorescent carpet.

  The fluorescent carpet according to the present invention is composed of a pile fabric composed of a pile layer 11 and a base fabric 15 that holds and locks the lower end of the pile 14, and a phosphorescent pigment between the pile fiber tip 13 and the base fabric 15 of the pile layer. The first feature is the interposition.

  The second feature of the fluorescent carpet according to the present invention is that, in addition to the first feature, the phosphorescent pigment constitutes the phosphorescent composition 16 together with the binder resin, and the phosphorescent composition 16 is a pile fiber of the pile 14. It exists in the point interposed between the pile fibers of the inside between the front-end | tip 13 and the base fabric 15. FIG.

  The third feature of the fluorescent carpet according to the present invention is that, in addition to the first feature, the phosphorescent pigment constitutes the phosphorescent composition 16 together with the binder resin and is fixed to the surface of the base fabric 15.

  A fourth feature of the fluorescent carpet according to the present invention is that, in addition to the first feature, a fluorescent sheet 17 is laminated on the surface of the base fabric 15, and a phosphorescent pigment is interposed in the fluorescent sheet 17. It is in.

  A fifth feature of the fluorescent carpet according to the present invention is that, in addition to the fourth feature, the fluorescent sheet 17 is composed of fluorescent fibers that are spun by kneading a phosphorescent pigment into a fiber polymer.

  The sixth feature of the fluorescent carpet according to the present invention is that, in addition to the fourth feature, the fluorescent sheet 17 is composed of a phosphorescent composition 16 comprising a phosphorescent pigment and a binder resin.

  According to a seventh feature of the fluorescent carpet of the present invention, in addition to the fourth feature, the fluorescent sheet 17 is configured by laminating a phosphorescent composition 16 comprising a phosphorescent pigment and a binder resin on a base sheet 18. There is in point.

  The eighth feature of the fluorescent carpet according to the present invention is that, in addition to any of the fourth, fifth, sixth and seventh features, the fluorescent sheet 17 has an adhesive 19 on the surface of the base fabric 15. It is in the point which is joined via.

  A ninth feature of the fluorescent carpet according to the present invention is that, in addition to any of the first, second, third, fourth, fifth, sixth, seventh, and eighth features, the phosphorescent pigment is a pile. The pile layer 11 is partially interposed between the fiber tip 13 and the base fabric 15, the light emitting pile 14 a in which the phosphorescent pigment is interposed between the pile fiber tip 13 and the base fabric 15, and the pile fiber tip 13 and the base This is because the phosphorescent pigment is formed between the cloth 15 and the non-light-emitting pile 14b without any interposition.

In addition to any of the first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth features, the tenth feature of the fluorescent carpet according to the present invention is a pile. The absolute bulk density of the pile layer 11 calculated by dividing the bulk density (δ) of the layer 11 by the specific gravity (ρ) of the pile fiber is 0.03 to 0.13 g / cm ³ .

The eleventh feature of the fluorescent carpet according to the present invention is that, in addition to the tenth feature, the absolute bulk density of the pile layer 11 is 0.065 to 0.1 g / cm ³ .

  A twelfth feature of the fluorescent carpet according to the present invention is any one of the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth and eleventh. In addition to the feature, the thickness (h) of the pile layer 11 is 4 mm or less.

  A thirteenth feature of the fluorescent carpet according to the present invention is the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh and twelfth aspects. In addition to any feature, the pile layer 11 is composed of a high pile having a long pile length (h) and a low pile having a short pile length (h), and the pile length (h) of the low pile is 4 mm or less. is there.

  A fourteenth feature of the fluorescent carpet according to the present invention is the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh, twelfth and In addition to any of the thirteenth features, the phosphorescent pigment is a phosphorescent phosphor comprising strontium aluminate and an activator.

  The fifteenth feature of the fluorescent carpet according to the present invention is the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh, twelfth, In addition to any of the thirteenth and fourteenth features, the lightness L value of the color of the pile 14a at the location where the phosphorescent pigment is interposed is 25 or more.

  On the pile surface of many printed carpets that have been printed, only the tip of 3-4 mm is colored from the tip of the pile, and the root that goes deeper than 4 mm from the tip of the pile remains uncolored fabric Although it remains, the color of the uncolored root part does not appear on the pile surface, and the aesthetics of the printed pattern drawn on the pile surface is not particularly affected by the color of the uncolored root part. Even carpets whose roots remain uncolored are commercially available as “printing carpets”. In the fluorescent carpet of the present invention, the phosphorescent pigment is interposed between the pile fiber tip 13 and the base fabric 15 and is not exposed on the pile surface, like the commercially available “printing carpet”. Therefore, even if it displays an evacuation guidance sign etc. (24), it does not become obstructive. However, in the darkness in the event of a power outage where the pile fiber tip 13 cannot be visually observed, the phosphorescent pigment emits fluorescence, and the fluorescence passes through the pile fiber gap and is exposed to the pile surface, which is visible for the first time in the dark. Become. Since the phosphorescent pigment is interposed between the pile fiber tip 13 and the base fabric 15 that is not rubbed against the shoe sole, it does not peel off from the pile surface when the fluorescent carpet is in use. Thus, according to the present invention, a fluorescent carpet having both decorativeness as an interior material and wear resistance as a flooring material can be obtained. On the other hand, even if the phosphorescent pigment is present inside the pile layer, the pile fiber is in a standing state, and external light enters between the standing pile fibers, so that the phosphorescent pigment absorbs light energy in a bright normal state. In the dark, the fluorescence of the phosphorescent pigment passes through the gaps between the pile fibers and appears on the pile surface, thereby making it possible to visually observe the evacuation guide signs (24) and to apply the phosphorescent pigment to the carpet. Is achieved.

In order to facilitate the transmission of external light from sunlight, indoor lighting, or fluorescence from phosphorescent pigments through the gaps between the pile fibers, the absolute bulk density of the pile layer should be 0.13 g / cm ³ or less, and the gaps between the pile fibers are Make it easy. However, if the absolute bulk density of the pile layer is too low, the carpet cushioning, sound absorption, heat retention, and other functions and durability will be impaired, and the pile layer will be easily worn away, and the phosphorescent pigment will peel off together with the pile fiber. It is difficult to expect the protective effect of the phosphorescent pigment by the pile layer. Therefore, in the present invention, the absolute bulk density of the pile layer 11 although a 0.03 g / cm ³ or more, preferably 0.05 to 0.1 / cm ^3, typically 0.08 g / cm ³ before and after (0. 065 to 0.095 g / cm ³ ).

In the present invention, the bulk density of the pile layer is not the apparent specific gravity or bulk density (δ) expressed as the mass of the pile layer in the unit volume (1 cm ³ ) of the pile layer, but the apparent specific gravity or bulk density ( δ) is defined by the “absolute bulk density of the pile layer” calculated by dividing by the specific gravity (ρ) of the pile fiber constituting the pile layer, because the apparent specific gravity of the pile layer Even if the bulk density (δ) is the same, if the specific gravity (ρ) of the pile fiber is changed, the porosity (gap) between the pile fibers of the pile layer is changed, so that the apparent specific gravity or bulk density (δ) of the pile layer is changed. ), The degree to which external light or fluorescence passes through the pile layer cannot be defined.

  The pile 14 may be a cut pile or a loop pile, but the pile fibers are in a wrinkle shape, and the pile fibers are difficult to separate, and the pile fibers that form the wrinkle shape are bulky. It is recommended that the shape of the pile 14 be a loop pile in that it is difficult to be crushed structurally and the phosphorescent pigment is not easily detached from the inside of the pile layer by being caught by a pile fiber that forms a ring shape.

  In the present invention, in order to interpose the phosphorescent composition 16 between the pile fiber tip 13 and the base fabric 15 and between the pile fibers inside the pile 14, a water- and oil-repellent antifouling agent 20 is applied to the pile surface. Then, the carpet is pretreated so that the liquid phosphorescent composition hardly adheres to the pile fiber tip 13, and then the liquid phosphorescent composition is applied to the pile layer and pressed to impregnate the liquid phosphorescent composition inside the pile layer. Then, in the process of releasing the pile layer 11 from the pressure and restoring the original thickness (bulk), the liquid phosphorescent composition adhering to the pile fiber tip 13 is absorbed into the pile layer, and the pile layer 11 The phosphorescent composition can be applied only between the pile fibers inside 14a. The liquid phosphorescent composition absorbed in the pile layer is then heated and solidified. Application of the water / oil repellent antifouling agent 20 to the pile surface is also recommended in order to maintain the lightness L value of the color of the pile 14a at the location where the phosphorescent pigment is interposed at 25 or more.

  The phosphorescent pigment can be prepared in such a liquid phosphorescent composition and interposed between pile fibers in the pile, or can be prepared in a liquid phosphorescent composition together with a binder resin and applied to the surface of the base fabric 15. Further, the phosphorescent pigment is kneaded into a fiber polymer to prepare a fluorescent fiber to obtain a fluorescent sheet 17, or a phosphorescent sheet 17 prepared by preparing a liquid phosphorescent composition together with a binder resin, or alternatively a phosphorescent prepared with a binder resin. The composition is laminated on the base sheet 18 to form a fluorescent sheet 17, which is superposed on the surface of the base fabric 15, needle punched or stitched as necessary, or bonded with an adhesive 19. Can be bonded to the base fabric surface 15 and interposed between the pile fiber tip 13 and the base fabric 15.

  When the phosphorescent pigment is prepared in a liquid phosphorescent composition and applied to the base fabric surface 15, or the phosphorescent sheet 17 is prepared and laminated on the base fabric surface 15, the pile layer 11 is laminated with the phosphorescent composition 16. The pile fabric 21 is formed (tufted) by inserting a pile yarn 21 into the base fabric 15 with a tufted machine with the laminated surface of the phosphorescent composition 16 facing the pile surface. When the fluorescent sheet 17 is bonded to the base fabric surface 15 by the adhesive 19, the adhesive 19 may be applied partially (dot-like) to either the base fabric surface or the back surface of the fluorescent sheet. Then, the resistance that the needle receives from the base fabric 15 and the fluorescent sheet 17 is small, and tufting becomes easy.

  The distance t between the pile fiber tip 13 (pile layer surface) and the lamination of the phosphorescent composition 16 is used in order for the phosphorescent pigment to easily absorb external light and to make the fluorescence emitted by the phosphorescent pigment easily appear on the pile surface. Generally, it is preferable to set the length to 1 to 3 mm so that the length becomes 4 mm or less. Accordingly, in a carpet having a pile length h of 5 mm or more, the distance (t) between the pile fiber tip 13 and the laminated phosphorescent composition 16 is adjusted by the thickness (m) of the fluorescent sheet 17, particularly the base sheet 18. As such, the fluorescent sheet 17 is particularly effective for carpets whose pile length (h) exceeds 5 mm.

  In order to adjust the distance t between the pile fiber tip 13 and the phosphorescent composition 16 by the base sheet 18, a high-magnification foamed resin sheet such as urethane foam, resin cotton with lightly bonded fibers between the fiber webs, two front and back sheets Thick and bulky sheet-like materials such as three-dimensional warp knitted fabric (double raschel fabric), needle punching felt, pile fabric, etc., in which the knitted fabric is connected with connecting yarns and the air layer is formed between the two front and back knitted fabrics 18 is used. In such a bulky base sheet 18, even if it is thick, it does not prevent the pile 14 planted on the base fabric 15 from being bulky and does not hinder tufting. The base sheet 18 is not required to have such a strength that the base sheet 18 is not torn by the needle during tufting and the dimensional stability that does not cause elastic deformation during use of the carpet, like the base cloth 15 that holds and locks the pile 14. .

In order to make the fluorescence emitted from the phosphorescent pigment easily appear on the pile surface, the depth (t) of the pile layer from the tip of the pile fiber reaching the phosphorescent composition 16 is 4 mm or less, and the absolute bulk density of the pile layer is 0.03. -0.13 g / cm ³ and the pile yarn 21 has a light-colored bright fiber with a lightness L value of 25 or more, particularly a bright bright fiber that contains almost no matting agent (titanium oxide). It is recommended that the lightness L value of the color of the pile 14a is 50 or more. The lightness L value of the color of the pile 14 is measured by a colorimeter “Spectrolino” from GretagMacbeth.

  The phosphorescent composition 16 does not need to be strongly fixed to the base sheet 18, and the degree of adhesion with the base sheet 18 may be such that the phosphorescent composition 16 does not peel off from the base sheet 18 in the tufting process. In this way, even if the phosphorescent composition 16 is lightly adhered to the base sheet 18, the dust adhered to the inside (11) of the pile layer during use of the carpet cannot be easily removed. In addition, the phosphorescent composition 16 never leaves the inside of the pile layer (11). This is the same in the case where the base sheet 18 and the base fabric 15 are bonded. Therefore, it is not always necessary to firmly bond the base sheet 18 to the base fabric 15 with the adhesive 19. Therefore, in the case of a carpet having a long pile length (h), the base sheet 18 may be simply overlapped with the base cloth 15, and it is sufficient that the base sheet 18 is temporarily locked to the base cloth 15 by performing needle punching. is there.

  In the thin pile layer 11 having a pile length (h) of 5 mm or less, a thin sheet such as a thin cloth, paper, or plastic film, or an adhesive tape can be used for the base sheet 18. Therefore, a commercially available phosphorescent adhesive tape as a decorative material can be used as the fluorescent sheet 17 as it is.

  A phosphorescent pigment is partially interposed between the pile fiber tip 13 and the base fabric 15, and the surface of the carpet is a light emitting pile 14 a in which the phosphorescent pigment is interposed between the pile fiber tip 13 and the base fabric 15, and the pile fiber The fact that the luminous pigment does not intervene between the tip 13 and the base fabric 15 is separated from the non-light emitting pile 14b. The fluorescence emitted by the luminous pigment appears in a pattern on the carpet surface when the light is extinguished, and its beauty can be seen. This is because the evacuation guide sign 24 appears on the pile surface by the fluorescence emitted by the phosphorescent pigment in the darkness of an emergency when a power failure occurs.

When the phosphorescent composition 16 is thinly laminated on the entire surface of the base fabric 15 or the thin fluorescent sheet 17 is laminated, the pile layer 11 is composed of a high pile having a long pile length (h) and a low pile having a short pile length (h). In the case of a fluorescent carpet having a low pile pile length (h) of 4 mm or less, the low pile is a light emitting pile 14a that emits fluorescence in the dark, and the high pile is a non-light emitting pile 14b that does not emit fluorescence in the dark. Therefore, in the fluorescent carpet in which the pattern is drawn on the pile surface due to the difference in pile length (h) between the high pile and the low pile, the evacuation guide sign 24 appears in a pattern on the pile surface along the pattern.
In the case where the evacuation guide sign 24 is partially revealed at a required portion of the pile surface, the phosphorescent composition 16 and the fluorescent sheet 17 are partially laminated at the required portion of the base cloth 15. Become.

The amount of the phosphorescent pigment used may be set so that the afterglow luminance of the light emitting pile 14a is 1.5 to 4.5 mcd / m ² when 30 minutes have elapsed after the light is turned off. As the phosphorescent pigment, it is effective to use a phosphorescent phosphor composed of strontium aluminate and an activator because the afterglow time of the emitted fluorescence is long. The phosphorescent phosphor comprising strontium aluminate and the activator is known as described above as the technical background of the present invention, and a commercially available phosphor can be used for it.

  A backing agent 22 is applied to the back of the base fabric, and the pile yarn 21 (back stitch) is adhered and fixed to the base fabric 15. A backing material 23 can be bonded to the back surface of the base fabric coated with the backing agent 22. The backing layer 12 is composed of a coating film of the backing agent 22 and a backing material 23. For the backing 23, a cloth or a foamed resin sheet is used.

  In the tile carpet, a thick backing layer 12 is formed by laminating and laminating vinyl chloride resin, asphalt, polyolefin resin, glass fiber mesh fabric, and glass fiber nonwoven fabric. In the carpet used as a dust control mat, an unvulcanized rubber sheet is used as the backing 23, and the unvulcanized rubber sheet is superimposed on the coating film of the backing agent 22 applied to the back of the base fabric and heated and vulcanized. Integrated.
