The "impossible environment" is an environment with a brightness of a miniature bulb, and specifically, an environment with a brightness of 8 to 10 lux.

The glossiness of the glossy layer arrangement region is 7 or more, preferably 10 or more, more preferably 20 or more, and further preferably 30 or more. If the glossiness of the glossy layer arrangement region is too small, it becomes difficult to visually recognize the pattern of the glossy layer 50 in an environment where the brightness is not sufficient. From the viewpoint of increasing the glossiness, the glossy layer 50 preferably has a metallic luster.

The color of the gloss layer 50 is not particularly limited as long as it can exhibit a predetermined glossiness in an environment where the brightness is not sufficient, but from the viewpoint of easily increasing the glossiness, a color exhibiting metallic luster, for example, gold. Silver (and a visible color) is preferred, especially gold. If it has a golden luster, it can be given a more luxurious feel. However, it is not necessary to realize gold or silver with gold or silver, and it is sufficient to realize gold or silver in a pseudo manner with another material.
As the preferred color regions of gold and silver that can exhibit a predetermined glossiness, the following colors are preferable in the color region of PANTONE (registered trademark) Metallic Coated CHIPS.
That is, PANTONE®: 10101C, 10102C, 10103C, 10104C, 10105C, 10077C, 10106C, 10107C, 10108C, 10109C, 10110C, 10111C, 10112C, 10113C, 10114C, 10115C, 10116C, 10117C, 10118C, 10119C, 10120C, 10121C, 10122C, 10123C, 10124C, 10125C, 10126C, 10127C, 10128C, 10130C, 10131C, 10132C, 10136C, 10137C, 10138C, 10142C, 10143C, 10403C, 10404C, 10405C, 10406C, 10407C, 10408C, 10409C 10192C, 10250C, 10251C, 10262C, 10263C, 10264C, 10435C, 10436C, 10310C 10334C, 10335C, 10336C, 10337C, 10338C, 10340C, 10341C, 10342C, 10343C, 10344C, 10345C, 10346C, 10347C, 10348C, 10349C 10352C, 10353C, 10354C, 10355C, 10356C, 10357C, 10358C, 10359C, 10360C, 10361C, 10362C, 10363C, 10364C, 10365C, 10366C, 10567C, 10368C, 10369C, 10370C, 10371C, 10372C, 10373C, 10374C, 10375C 10378C, 10379C, 10380C, 10381C, 10446C, 10447C, 10448C, 10382C, 10383C, 10384C, 10449C, 10450C, 10451C, 10388C, 10389C, 10390C, 10391C, 10394C, 10395C, 10396C, 871C, 872C, 873C, 874C 876C, 877C, 8001C, 8002C, 8003C, 8004C, 8005C, 8006C, 8020C, 8021C, 8022C, 8040C, 8041C, 8042C, 8060C, 8061C, 8080C, 8100C, 8120C, 8121C 8160C, 8161C, 8180C, 822 0C, 8221C, 8200C, 8201C, 8280C, 8281C, 8240C, 8241C, 8260C, 8261C, 8300C, 8301C, 8320C, 8340C, 8341C, 8342C, 8360C, 8361C, 8362C, 8363C, 8364C, 8365C, 8380C, 8381C 8383C, 8384C, 8385C, 8400C, 8401C, 8402C, 8403C, 8420C, 8421C, 8422C, 8423C, 8440C, 8441C, 8500C, 8460C, 8461C, 8462C, 8580C, 8640C, 8461C, 8642C, 8634C, 8644C, 8645C 8661C, 8662C, 8680C, 8700C.

The gloss layer 50 is formed of, for example, a foil or paint containing metal. The foil is a thin, flat layer containing metal. Examples of the foil include those in which a metal is struck and spread thinly and flatly, those in which a synthetic resin layer and the like are laminated on a thinly flattened material, and those in which a synthetic resin layer and the like are laminated on a layered material containing metal. Can be mentioned. The layered material containing a metal is, for example, a metal powder pigment-containing coating film or a metal vapor deposition film. Examples of the paint include those containing a pigment or dye having a metallic luster, such as a metal powder pigment, as a coating film-forming component. In materials containing these various metals, the metals used for luster include, for example, gold, silver, copper, tin, brass and aluminum.

Here, the glossy layer 50 is preferably formed of foil. Such foils have a certain shape and thickness as compared to liquid materials such as paints. Therefore, the glossy layer 50 can be formed relatively smoothly with a desired thickness without being affected by the unevenness and voids of the base on which the foil is formed, and the glossiness of the glossy layer 50 can be easily maintained at a desired value. The thickness of the glossy layer 50 is preferably 1 to 1000 μm, preferably 10 to 200 μm. If the thickness of the gloss layer 50 is too thin, it will be affected by the unevenness of the base and the gloss cannot be maintained, and if it is too thick, the tactile sensation will be hard and the wearer or the like will feel uncomfortable.

In the present embodiment, the material of the foil is a foil composed of five layers: a base film / release layer, a coloring layer, a thin-film deposition layer, and an adhesive layer. The foil is transferred to the object to be transferred by a foil stamping method (hot stamping method). By the foil stamping method, the release layer to the adhesive layer are transferred to the transferred material, leaving the base film. Therefore, in this case, the foil of the glossy layer 50 can be said to be a portion from the release layer to the adhesive layer. The foil stamping method will be described later.

The base film is a layer for carrying a release layer, a colored layer, a thin-film deposition layer and an adhesive layer, and is formed of, for example, a predetermined synthetic resin. The release layer is a layer for facilitating the separation of each of the colored layer, the vapor-deposited layer, and the adhesive layer from the base film, and is formed of a predetermined synthetic resin. The colored layer is a layer that expresses the color of the foil. For example, when it is desired to develop a golden color on the foil, a coating film using a yellow paint is exemplified as the colored layer. The thin-film deposition layer is a layer that gives gloss. For example, when it is desired to develop a golden color on the foil, examples of the vapor-deposited layer include an aluminum thin film and a tin thin film vapor-deposited on the colored layer. The yellow coating film (colored layer) on which an aluminum thin film or a tin thin film (deposited layer) is vapor-deposited looks golden. The adhesive layer is formed by applying an adhesive to the vapor-deposited layer. As the adhesive, a suitable type is selected depending on the material to be transferred to which the foil is transferred. For example, when the material to be transferred is a non-woven fabric, a laminate, or a film, an adhesive layer suitable for each is selected. The adhesive adheres to the object to be transferred by heat and pressure. If you want to change the color of the metallic luster of the foil, for example, change the color of the colored layer. The tin thin film is preferable because it can avoid the reaction of the metal detector in the inspection by the metal detector at the time of manufacturing diapers and the like.

The glossy layer 50 is not limited to the above example, and may not necessarily be a foil or paint containing a metal as long as it can exhibit a predetermined glossiness in an environment where the brightness is not sufficient. Examples of the glossy layer 50 include a film using a paint containing a glossy pigment (example: a coating film containing a pearl pigment), a hologram, and the like.

In such a tape-type diaper 1, since the glossy layer 50 is formed of foil, it is possible to suppress the glossiness of the glossy layer arrangement region from being affected by the unevenness of the base. As a result, when the tape-type diaper 1 is to be used, the glossy layer 50 can be easily confirmed even in an environment where the lighting cannot be brightened. Therefore, the tape-type diaper 1 can be easily replaced even in an environment where the brightness is not sufficient.

In the present embodiment, the pair of engaging tapes 7a and 7b are provided with other glossy layers 52a and 52b having other patterns on the surface on the non-skin side. The configurations of the other gloss layers 52a and 52b are the same as the configurations of the gloss layer 50 described above, except that the positions where they are arranged are different. The other glossy layers 52a and 52b may be the same as the glossy layer 50, and may be different from each other within the range of the configuration of the glossy layer 50 described above.

In the present embodiment, the target tape region AA is specifically composed of a central portion AC located in the center in the width direction W, one side portion AEa located on both sides of the central portion AC, and the other side portion AEb. have. The target tape 18 includes a first tape portion 18a located on one side portion AEa and a second tape portion 18b located on the other side portion AEb and separated from the first tape portion 18a in the width direction W. .. That is, the target tape 18 is separated into a first tape portion 18a and a second tape portion 18b. At this time, the gloss layer 50 is located in the central portion AC of the target tape region AA. Then, the pair of engaging tapes 7a and 7b are engaged with one side portion AEa and the other side portion AEb of the target tape region AA when the tape type diaper 1 is worn.

In this case, as shown in FIG. 4, when the tape-type diaper 1 is worn, the pair of engaging tapes 7a and 7b are engaged with the both side portions AEa and AEb in the width direction W in the target tape region AA. That is, in the width direction W, the tape-type diaper 1 is correctly worn so that the glossy layer 50 is located in the central portion AC and the other glossy layers 52a and 52b are located on both sides of the target tape region AA. You can wear it. In this way, in the tape-type diaper 1, the pair of engaging tapes 7a and 7b can be guided to be arranged at the optimum positions on the target tape 18. Therefore, even in an environment where the lighting cannot be brightened, the positions of the target tape 18 and the pair of engaging tapes 7a and 7b of the tape-type diaper 1 can be easily recognized, and the pair of engaging tapes 7a and 7b can be used as the target tape 18. It can be easily engaged in the optimum position.

Further, the other glossy layer 52a, the glossy layer 50, and the other glossy layer 52b may be represented by a set pattern completed by arranging them in this order. In that case, when the tape-type diaper 1 is worn, when the other glossy layer 52a, the glossy layer 50, and the other glossy layer 52b are arranged in this order on the target tape 18 along the width direction W and are engaged with each other. With the pattern expression that is completed for the first time, it is possible to produce the high design and luxury of the tape-type diaper 1.

The glossy layer 50 may be intermittently or continuously arranged at any plurality of locations in the ventral portion 2, the dorsal portion 3, and the crotch portion 4, and the ventral portion 2, the dorsal portion 3 and the crotch portion 4 may be arranged intermittently or continuously. It may be arranged so as to straddle some of the crotch portions 4. For example, the glossy layer 50 is intermittently or continuously arranged from one engaging tape 7a to the other engaging tape 7b via the target tape 18 to surround the waist opening of gold. It can also be a high-class design like a belt.

In the present embodiment, the gloss layer 50 includes a base material 20 and a gloss forming layer 51. The base material 20 is located on the exterior sheet 5. The gloss-forming layer 51 is located on the base material 20, forms a pattern, and has gloss. Therefore, it can be said that the gloss-forming layer 51 is a portion of the gloss layer 50 formed of a foil or paint containing a metal. The gloss forming layer 51 is located between the first tape portion 18a and the second tape portion 18b in the width direction W. The base material 20 extends on both sides in the width direction W, and the first tape portion 18a and the second tape portion 18b are located on the base material 20.

As described above, in the tape-type diaper 1, the gloss-forming layer 51 is supported by the base material 20, and the first tape portions 18a and the second tape portions 18b located on both sides of the gloss-forming layer 51 are supported by the base material 20. Has been done. Therefore, the smoothness of the gloss forming layer 51 can be suppressed from being affected by the unevenness of the base and the unevenness of the base of the surrounding first tape portion 18a and the second tape portion 18b, and the gloss of the gloss forming layer 51 can be maintained. .. As a result, it is possible to suppress the glossiness of the glossy layer arrangement region from being affected by the unevenness of the base. Therefore, when the tape-type diaper 1 is to be used, the glossy layer 50 can be easily confirmed even in an environment where the lighting cannot be brightened. Therefore, the tape-type diaper 1 can be easily replaced even in an environment where the brightness is not sufficient.

The glossy layers 52a and 52b of the pair of engaging tapes 7a and 7b may also have a structure in which the base material and the gloss-forming layer are laminated, as in the case of the glossy layer 50. That is, each of the glossy layers 52a and 52b includes a base material located on each of the pair of engaging tapes 7a and 7b, and a glossy forming layer located on the base material, forming a pattern, and having gloss. You may be.

Here, examples of the base material 20 include non-woven fabrics such as spunbonded non-woven fabrics, air-through non-woven fabrics, and SMS non-woven fabrics. The material of the non-woven fabric is not particularly limited, and examples thereof include synthetic resins such as polyethylene, polypropylene, and polyethylene terephthalate. In that case, the thickness of the non-woven fabric is, for example, 0.02 to 2 mm, preferably 0.05 to 1 mm. If it is too thin, the material of the glossy layer 50 can easily come off the non-woven fabric, making it difficult to form the glossy layer 50. If it is too thick, the glossy layer 50 may protrude too much from the surface of the product. The density of the nonwoven fabric, the lower limit mentioned, for example, 0.04 g / cm ^3, preferably 0.07g / cm ^3, 0.09g / cm is more preferable. Upper limit include for example 2 g / cm ^3, preferably from ^{1g / cm 3, 0.5g / cm} 3 is more preferable. If the density is too low, there are many voids between the fibers, and the glossy layer 50 also has irregularities in the portion where the fibers do not exist, so that the glossiness is easily lowered and the glossiness is easily peeled off. If the density is too high, the base material 20 becomes hard and the tactile sensation tends to deteriorate. With this base material 20, the smoothness of the gloss forming layer 51 can be further suppressed from being affected by the unevenness of the base material below the base material 20. Therefore, the gloss-forming layer 51 can be evenly bonded onto the non-woven fabric to prevent it from peeling off. Further, the glossiness of the glossy layer arrangement region can be further suppressed from being affected by the unevenness of the base. Therefore, when the tape-type diaper 1 is to be used, the glossy layer 50 can be more easily confirmed even in an environment where the lighting cannot be brightened.

Here, when a non-woven fabric is used as the base material 20, the non-woven fabric may include a film (not shown) laminated on the surface opposite to the gloss-forming layer 51. The material of the film is not particularly limited, and examples thereof include synthetic resins. In that case, the smoothness of the gloss-forming layer 51 can be further suppressed from being affected by the unevenness of the base material below the base material 20. Therefore, the gloss-forming layer 51 can be evenly bonded onto the non-woven fabric to prevent it from peeling off. Further, the glossiness of the glossy layer arrangement region can be further suppressed from being affected by the unevenness of the base material below the base material. That is, the glossiness of the glossy layer 50 can be increased as compared with the case where there is no film. As a result, when the tape-type diaper 1 is to be used, the glossy layer can be more easily confirmed even in an environment where the lighting cannot be brightened. Further, since the thickness of the base material 20 is increased by the amount of the laminated film, pressure is easily applied between the foil and the base material 20 during the foil pressing process for the gloss forming layer 51, and the foil is the base. It becomes easy to be placed on the material 20.

Here, when a non-woven fabric is used as the base material 20, the non-woven fabric may be heat-pressed. In that case, the smoothness of the base material 20 can be improved by heat-sealing and thermocompression-bonding the fibers of the non-woven fabric. Therefore, the smoothness of the gloss-forming layer 51 can be further suppressed from being affected by the unevenness of the base material below the base material 20. Therefore, the gloss-forming layer 51 can be evenly bonded onto the non-woven fabric to prevent it from peeling off. Further, it is possible to further suppress that the glossiness of the glossy layer arrangement region is lowered due to the influence of the unevenness of the base material below the base material 20. That is, the glossiness of the gloss layer 50 can be increased as compared with the case where it is not heat-pressed. As a result, when the tape-type diaper 1 is to be used, the glossy layer 50 can be more easily confirmed even in an environment where the lighting cannot be brightened. Further, when the base material 20 is smoothed by a hot press or the like (including the case where the base material 20 is originally smooth), the entire gloss layer 50 including the gloss forming layer 51 becomes very smooth, so that it is tactile. The glossy layer 50 can be confirmed more easily.

Here, when a non-woven fabric is used as the base material 20, a base coat layer (not shown) may be further provided between the non-woven fabric and the gloss-forming layer 51. In that case, the surface of the non-woven fabric is covered with the base coat, and the smoothness of the base material can be improved. Therefore, it is possible to further suppress the glossiness of the glossy layer arrangement region from being affected by the unevenness of the base material below the base material 20. That is, the glossiness of the glossy layer 50 can be increased as compared with the case where there is no base coat layer. As a result, when the tape-type diaper 1 is to be used, the glossy layer 50 can be more easily confirmed even in an environment where the lighting cannot be brightened. Further, the bonding strength between the non-woven fabric and the gloss forming layer 51 can be increased.

Here, when a non-woven fabric is used as the base material 20, a top coat layer (not shown) may be further provided on the gloss-forming layer 51 on the non-woven fabric. In that case, since the top coat layer is provided on the gloss forming layer 51, the deformation of the gloss forming layer 51 can be suppressed, and unevenness and wrinkles can be less likely to be formed. Therefore, the glossiness of the glossy layer arrangement region maintains the smoothness of the surface of the gloss-forming layer 51, so that the glossiness of the glossy layer 50 can be maintained. That is, the glossiness of the glossy layer 50 can be increased as compared with the case where there is no topcoat layer. As a result, when the tape-type diaper 1 is to be used, the glossy layer 50 can be easily confirmed even in an environment where the lighting cannot be brightened. Further, the non-woven fabric can be protected by the top coat layer, and the peeling of the gloss layer 50 (gloss forming layer 51) can be suppressed.

The configuration of the target tape 18 and the glossy layer 50 is not limited to the above example, and if the glossy layer 50 can be easily confirmed in an environment where the brightness is not sufficient, and thus the position of the target tape 18 can be easily confirmed. , Other configurations may be used, as exemplified below.

FIG. 5 is a cross-sectional view showing another configuration example of the tape-type diaper 1 according to the embodiment. In this tape-type diaper 1, the base material 20 does not extend on both sides in the width direction W, but exists only on the lower side of the gloss forming layer 51, and on the lower side of the first tape portion 18a and the second tape portion 18b. not exist. In this tape-type diaper 1, the gloss-forming layer 51 of the gloss layer 50 is supported by the base material 20. Therefore, the smoothness of the gloss forming layer 51 can be suppressed from being affected by the unevenness of the base, and the gloss of the gloss forming layer 51 can be maintained. As a result, the glossiness of the glossy layer arrangement region can be suppressed from being affected by the unevenness of the base of the glossy cambium. Further, the gloss-forming layer 51 is located at a position higher than that of the first tape portion 18a and the second tape portion 18b by the base material 20, and protrudes appropriately. As a result, when the tape-type diaper 1 is to be used, the glossy layer 50 can be easily confirmed even in an environment where the lighting cannot be brightened. Therefore, the tape-type diaper 1 can be easily replaced even in an environment where the brightness is not sufficient. Further, by forming the gloss forming layer 51 on the base material 20 which is not the target tape 18 (first tape portion 18a + second tape portion 18b), the pair of engaging tapes 7a and 7b are respectively formed on the gloss forming layer 51. Never engage. As a result, it is possible to prevent the gloss-forming layer 51 from peeling off due to engagement and to prevent the gloss-forming layer 51 from becoming invisible after engagement.

FIG. 6 is a cross-sectional view showing another configuration example of the tape-type diaper 1 according to the embodiment. In this tape-type diaper 1, the base material 20 is a part of the target tape 18. That is, a part of the target tape 18 functions as the base material 20. The gloss-forming layer 51 is arranged in the central portion of the target tape 18 in the width direction W (the central portion AC of the target tape region AA). In this case, the gloss forming layer 51 of the gloss layer 50 is supported by the target tape 18. Therefore, the smoothness of the gloss forming layer 51 can be suppressed from being affected by the unevenness of the base, and the gloss of the gloss forming layer 51 can be maintained. Therefore, it is possible to suppress that the glossiness of the gloss layer arrangement region is affected by the unevenness of the base of the gloss forming layer 51. As a result, when the tape-type diaper 1 is to be used, the glossy layer 50 can be easily confirmed even in an environment where the lighting cannot be brightened. Therefore, the tape-type diaper 1 can be easily replaced even in an environment where the brightness is not sufficient. Further, by forming the gloss forming layer 51 on the target tape 18, after visually recognizing the gloss forming layer 51, a pair of engaging tapes 7a and 7b can be engaged on the gloss forming layer 51 and its surroundings. A wider area can be secured for engagement. Thereby, the engagement between the target tape 18 and the pair of engaging tapes 7a and 7b can be further stabilized. A base material 20 having substantially the same size as the gloss forming layer 51 as shown in FIG. 5 may be interposed between the gloss forming layer 51 and the target tape 18.

FIG. 7 is a cross-sectional view showing another configuration example of the tape-type diaper 1 according to the embodiment. In this tape-type diaper 1, the base material 20 is a part of the exterior sheet 5 on the surface on the non-skin side. That is, a part of the exterior sheet 5 functions as the base material 20. In this case, the gloss-forming layer 51 and the first tape portion 18a and the second tape portion 18b of the target tape 18 are supported by the exterior sheet 5. Therefore, the smoothness of the gloss forming layer 51 can be suppressed from being affected by the unevenness of the base, and the gloss of the gloss forming layer 51 can be maintained. Therefore, it is possible to further suppress that the glossiness of the gloss layer arrangement region is affected by the unevenness of the base of the gloss forming layer 51 and the unevenness of the base of the surrounding first tape portion 18a and the second tape portion 18b. As a result, when the tape-type diaper 1 is to be used, the glossy layer 50 can be more easily confirmed even in an environment where the lighting cannot be brightened. Therefore, the tape-type diaper 1 can be easily replaced even in an environment where the brightness is not sufficient. In this case, when there is no exterior sheet 5 and the back surface sheet 13 constitutes the surface on the non-skin side, the base material 20 is a part of the back sheet 13 on the front surface on the non-skin side.

In each of the above configuration examples, the target tape 18 and the pair of engaging tapes 7a and 7b are provided with the gloss layer 50 and the gloss layers 52a and 52b, respectively, but the arrangement of the gloss layers is not limited to these examples. The gloss layer may be arranged only on one of the target tape 18 and the pair of engaging tapes 7a and 7b. For example, in the tape-type diaper 1, when the target tape 18 does not have a glossy layer and the pair of engaging tapes 7a and 7b have glossy layers 52a and 52b, the tape-type diaper 1 even in an environment where the illumination cannot be brightened. The positions of the pair of engaging tapes 7a and 7b can be easily recognized. In particular, the pair of engaging tapes 7a and 7b are easily laid under the body when the tape-type diaper 1 is replaced, and it is difficult to visually recognize the pair of engaging tapes 7a and 7b in an environment where the lighting cannot be brightened. Therefore, the pair of engaging tapes 7a and 7b can be easily visually recognized by the glossy layers 52a and 52b, so that the tape-type diaper 1 can be easily replaced.

Next, a method for forming the glossy layer 50 in the method for manufacturing the tape-type diaper 1 will be described.
The method for forming the glossy layer 50 is not particularly limited as long as a predetermined glossy layer 50 can be formed. As the forming method, for example, (1) a step of preparing a sheet member for the base material 20, and (2) a step of arranging a material (foil: foil, paint) for the gloss forming layer 51 on the surface of the sheet member. , (3) A step of cutting out a portion of the sheet member on which the gloss forming layer 51 is arranged, and (4) a step of arranging the cut-out portion on a predetermined base sheet member.

However, examples of the sheet member for the base material 20 prepared in the above step (1) include a sheet member for the base material 20 (example: in the case of FIGS. 3 and 5) and a sheet member for the target tape 18. Example: In the case of FIG. 6, a sheet member for the engaging tape 7 (Example: In the case of FIG. 2), a sheet member for the exterior sheet 5 (Example: in the case of FIG. 7), a sheet member for the back surface sheet 13, and the like. Examples include heat-pressed sheet members. Here, when the sheet member for the base material 20 is the sheet member for the base material 20, the base sheet member in the above step (4) is for the exterior sheet 5, the back surface sheet 13, the engaging tape 7, or the target tape 18. It is a seat member for. When the sheet member for the base material 20 is the sheet member for the target tape 18, the base sheet member in the step (4) above is a sheet member for the exterior sheet 5 or the back surface sheet 13. When the sheet member for the base material 20 is a sheet member for the engaging tape 7, the exterior sheet 5, or the back sheet 13, the steps (3) and (4) above for forming the glossy layer 50 are unnecessary. is there.

Among the methods for producing the tape-type diaper 1 (the method for forming the glossy layer 50 in the above), the step (2) above includes a smoothing step and a forming step. The smoothing step smoothes the surface of the sheet member for the surface on the non-skin side (eg, the sheet member for the base material 20). In the forming step, a glossy layer having a pattern (example: glossy forming layer 51) is formed on the surface of the smoothed sheet member. At that time, the glossiness of the glossy layer arrangement region including the glossy layer becomes 7 or more.

Here, the smoothing step may include a heat treatment step of applying heat to the sheet member and a pressure step of applying pressure to the sheet member (heat press). Examples of the heat treatment step include a step of passing a sheet member between a pair of heating rolls. The temperature of the heating roll is preferably equal to or higher than the softening point of the material of the sheet member and lower than the melting point. Specifically, although it depends on the material of the sheet member, for example, 80 to 180 ° C. is mentioned, and 90 to 150 ° C. is preferable. The heating time is, for example, 0.01 to 2 seconds, preferably 0.05 to 0.1 seconds. Examples of the pressure step include a step of passing a sheet member between a pair of pressure rolls. Examples of the pressure of the pressure roll include 0.1 to 5 MPa, preferably 0.3 to 3 MPa. The pressurization time is, for example, 0.01 to 2 seconds, preferably 0.05 to 0.1 seconds. However, the heat treatment step and the pressure step may be performed at the same time. In that case, for example, a step of passing the sheet member between the pair of rolls can be mentioned. The roll temperature, roll pressure, heating or pressurizing time are as described above.

The "softening point" and "melting point" are the "endothermic start temperatures" when measuring the endothermic behavior that changes from a solid state to a liquid at a temperature rise rate of 10 ° C./min, respectively, with a differential scanning calorimeter. And "peak top temperature".

The smoothing step can improve the smoothness of the sheet member. The density of the sheet member is used as an index of the smoothness of the sheet member. This is because in a sheet member such as a non-woven fabric, as the density increases, the distance between the fibers becomes shorter and the fibers come close to each other to reduce surface irregularities, and thus smoothing progresses. The density of the sheet member after the smoothing step is preferably about twice or more the density before the smoothing step. As a specific density of the sheet member, for example, 0.07 g / cm ³ or more is preferable, 0.09 g / cm ³ or more is more preferable, and 0.2 g / cm ³ or more is even more preferable.

On the other hand, the forming step is a foil pressing step in which a foil containing a metal having a pattern is thermocompression bonded to the surface of the smoothed sheet member, or a pattern is formed on the surface of the smoothed sheet member with a paint containing a metal. Includes a printing process, which prints.

In the foil pressing process, the foil is pressed against the transferred material (example: sheet member) by heat and pressure, and the layer having the color of the foil (example: the metal foil itself, the five-layer foil coloring layer and the vapor deposition layer). Is a method of thermocompression bonding to the transferred material. The foil stamping method is preferable because it is a dry method in which a metallic color (metallic luster) can be easily expressed on the transferred material and does not use a solvent, unlike ordinary printing. In the above-mentioned five-layer foil, the release layer to the adhesive layer are transferred to the transferred material by the foil pressing method, leaving the base film. However, when the foil pressing process is used as the forming process, smoothing is not always necessary because of the characteristics of the foil, which has a constant shape and thickness and is not easily affected by the smoothness of the substrate.

The printing process is not particularly limited, and examples thereof include pad printing, gravure printing, flexo printing, screen printing, inkjet printing, and printing, and pad printing is preferable. The reason is that since printing is performed with an elastic silicon pad, it is possible to print on uneven surfaces such as the surface of non-woven fabric, and because transfer printing can be performed multiple times at the same location, the film thickness increases. This is because it is possible to increase the film thickness even though it is printed, and it is easy to enhance the glossiness. In the case of the printing process, the printing process may be repeated a plurality of times in order to make the gloss layer 50 (gloss forming layer 51) a desired thickness.

Before the forming step, a step of forming a base coat layer on the surface of the smoothed sheet member may be provided. Further, after the printing step, there may be a step of forming a top coat layer on the gloss forming layer 51.

In such a method for manufacturing the tape-type diaper 1, the glossy layer 50 (glossy forming layer 51) is formed after the surface of the sheet member is smoothed. Therefore, the glossy layer arrangement including the glossy layer 50 (glossy forming layer 51) is provided. The glossiness of the region can be surely set to 7 or more. Therefore, it is possible to manufacture the tape-type diaper 1 that can facilitate the replacement of the tape-type diaper 1 even in an environment where the brightness is not sufficient.
