Since a hook and loop fastener member is provided, the sheet can be easily attached or detached. Further, the hook material is thin and has a thickness of 600 μm or less, and a nonwoven fabric or a knitted fabric which can be engaged with the hook material can be used as the loop material. Thus, a hook and loop fastener member is obtained that is lightweight, easy to carry, and flexible to change. Further, since the thickness of the engaging portion of the hook and loop fastener member can be made relatively small, sheet bulkiness after the sheet has been fixed on a supporting surface can be suppressed. Therefore, superior attachment and natural appearance of the sheet can be achieved.

For the sheets according to the present disclosure, the use of the sheets is not limited by the various embodiments shown below. For example, the sheet can be used as a graphic sheet, a projector screen, a whiteboard sheet, a sheet for a sticky note, or a decorative sheet for interior and exterior of a building.

Sheet 1 can be adhered to any tangible object. In the present disclosure, "adhering a sheet" and "attaching a sheet" both indicate that the sheet is fixed to any tangible object.

Alternatively, the substrate 21a and/or the ring layer 21b may comprise polyethylene, polypropylene, polyester, or the like when considering material cost or environmental safety.

Regardless of the type and material of the loop material 21, the mating face of the loop material 21 may have a region that does not include a loop. In the present disclosure, the area not including the ring is referred to as a "loop-free region" for the sake of convenience. The method of forming the acyclic region is not limited, and for example, heat sealing can be employed. It should be noted that the "heat sealing" indication partially suppresses the ring erection, for example, by heat sealing and/or hot pressing using a heating roller shaft or the like. The ratio of the area of the acyclic region to the total area of the loop material 21 can be determined based on various viewpoints, such as maintenance of the meshing force with the second hook and loop fastener member, ease of detachment from the second hook and loop fastener member, and Cost of production. For example, the lower limit of the ratio may be 5%, 10%, 15%, 20%, 25%, or 30, and the upper limit may be 50%, 45%, 40%, 35%, or 30%. The shape and configuration of the acyclic area are not limited. For example, the acyclic regions may be configured in the form of a plurality of lines extending parallel to each other, may be arranged in a lattice form, may be distributed regularly or irregularly, or may be randomly arranged.

In one embodiment, the lower limit of the weight average molecular weight of the adhesive homopolymer or copolymer may be about 200,000 or about 400,000, and the upper limit may be about 1,000,000. Or about 700,000. The weight average molecular weight of the adhesive homopolymer or copolymer is determined by gel permeation chromatography (GPC) using standard polystyrene.

The adhesive acrylic based polymer can be crosslinked by a crosslinking agent. Examples of useful crosslinking agents include isocyanate compounds, melamine compounds, poly(meth)acrylate compounds, epoxy compounds, guanamine compounds, and bis-amine compounds, and diaziridine derivatives of dibasic acids, such as 1,1'-m-xylylenedicarboxy-bis(2-methylaziridine). As the crosslinking agent, an isocyanate compound (for example, hexyl diisocyanate) can be used, and a bis-indenylamine compound (for example, 1,1'-m-xylylenedi- bis(2-methylaziridine)) can be used. The amount of the crosslinking agent to be added also depends on the type of the crosslinking agent; however, the crosslinking agent is generally added in an amount of from 0.1 part by mass to 10 parts by mass per 100 parts by mass of the acrylic-based pressure-sensitive adhesive.

The smaller thickness of the adhesive layer 13 contributes to incombustibility, and the greater thickness of the adhesive layer 13 increases the adhesion strength. The lower limit of the thickness of the adhesive layer 13 may be, for example, 10 μm or 20 μm from the viewpoint of balance incombustibility and adhesion strength, and the upper limit thereof may be 200 μm or 100 μm.

The fastener layer 12 of the sheet 1 includes a loop material 21 as a first hook and loop fastener member. On the support surface 90 of the tangible object, the hook material 22 is secured as a second hook and loop fastener member corresponding to the fastener layer 12 (loop material 21). The attachment of the second hook loop fastener member to the support surface 90 is not limited. The hook material 22 may be provided only at a portion corresponding to the shape and area of the sheet 1, and for example, the hook material 22 may be provided only at a position corresponding to a portion or the entirety of the peripheral edge of the sheet 1. Alternatively, the hook material 22 may be provided on the entirety corresponding to the shape and area of the sheet 1. sheet The shape and area of the first hook and loop fastener (ring material 21) of the material 1 may be different from the shape and area of the second hook and loop fastener (hook material 22) on the support surface 90. Thus, when the sheet 1 is adhered to the support surface 90, one of the first hook and loop fasteners (loop material 21) does not have to be engaged with the second hook and loop fastener (hook material 22). Further, at the time of adhesion, a portion of the second hook and loop fastener (hook material 22) does not have to be engaged with the first hook and loop fastener (ring material 21). It should be noted that although not shown in FIG. 1, the hook material 22 may be secured to the support surface 90 by an adhesive layer or the like.

The sheet 1 adhered to the support surface 90 can be easily detached by using the first hook and loop fastener and the second hook and loop fastener, and further, the detached sheet 1 can be adhered to the support surface 90 again. That is, as shown by an arrow A in Fig. 1, the sheet 1 can be attached and detached at will. As shown in FIG. 3, by providing a second hook and loop fastener member (hook material 22) around the outer edge of the sheet 1, the sheet 1 can be repeatedly spread on the support surface 90 and the sheet 1 can be rolled up and fixed. . Further, after the sheet 1 adhered to a tangible object is detached, the sheet 1 may be adhered to another tangible object or may be attached to the same place again later. In other words, the sheet 1 can be reused without impairing the quality of the sheet 1.

By appropriately setting the 90° peel adhesion strength (90° peel strength) of the sheet 1, the sheeting force can be maintained while the sheet 1 is adhered, and at the same time, the sheet 1 can be easily detached. The 90° peel adhesion strength is the strength measured when the second hook and loop fastener member is detached from the sheet 1, and can be measured, for example, by the method specified in JIS Z 0237. The lower limit of the 90° peel adhesion strength may be, for example, 0.5 N/25.4 mm or 1.0 N/25.4 mm from the viewpoint of maintaining the meshing force. From the point of view of easy detachment, 90° peel adhesion strength The upper limit may be, for example, 8N/25.4 mm, 6N/25.4 mm, 4N/25.4 mm, or 2N/25.4 mm.

Figure 4 is a cross-sectional view of a sheet 1A according to an embodiment. The sheet 1A includes a film layer 2, a fastener layer 12A, and an adhesive layer 13. The film layer 2 and the fastener layer 12A are joined by the adhesive layer 13. The sheet 1A differs from the sheet 1 in that the first hook and loop fastener member does not include a loop material but includes a hook material. The fastener layer 12A different from the sheet 1 is specifically described below.

The fastener layer 12A is a sheet-like member to adhere the sheet 1A to any tangible object and includes a hook material 22 as a first hook and loop fastener member. The fastener layer 12A may be provided on one of the back faces 2b of the film layer 2 or may be provided on the entirety of the back face 2b.

In an example of FIG. 4, a loop material 21 as a second hook and loop fastener member corresponding to the fastener layer 12A (hook material 22) is secured to the support surface 90 of the tangible object. The fixing of the second hook and loop fastener member on the support surface 90 can be selected manually, which is the same in the case of the sheet 1. The shape and area of the first hook and loop fastener (hook material 22) of the sheet 1A may be different from the shape and area of the second hook and loop fastener (ring material 21) on the support surface 90. Therefore, when the sheet 1A is adhered to the support surface 90, one of the portions of the first hook and loop fastener (hook material 22) does not have to be engaged with the second hook and loop fastener (ring material 21). Further, one portion of the second hook and loop fastener (ring material 21) does not have to be engaged with the first hook and loop fastener (hook material 22) upon adhesion. As shown by the arrow A in Fig. 4, the sheet 1A can be arbitrarily attached and detached. Note It is to be noted that although not shown in FIG. 4, the loop material 21 may be secured to the support surface 90 by an adhesive layer or the like.

The material of the hook material 22 is not limited. For example, the material is a thermoplastic resin, and specifically may be a polypropylene resin (PP), a polyethylene resin (PE), a vinyl chloride resin (PVC), an ethyl methyl methacrylate resin (EMMA), ethyl acrylate. Resin (EA), ethylene vinyl acetate copolymer (EVA) resin, a mixture of two or more types (for example, a mixture of polypropylene resin (PP) and polyethylene resin (PE), polypropylene a mixture of a resin (PP) and an ethyl methyl methacrylate resin (EMMA), a mixture of a polypropylene resin (PP) and an ethyl acrylate resin (EA), a copolymer of a polypropylene resin (PP) and ethylene vinyl acetate a mixture of one of the (EVA) resins, a mixture of a polyethylene resin (PE) and an ethyl methyl methacrylate resin (EMMA), a mixture of a polyethylene resin (PE) and an ethyl acrylate resin (EA), and a mixture of polyethylene resin (PE) and ethylene vinyl acetate copolymer (EVA) resin). It should be noted that examples of PE include low density polyethylene (LDPE), high density polyethylene (HDPE), and linear low density polyethylene (LLDPE). Additives or the like may be added to such resins as needed.

The shape of the hook 22b is not limited as long as the engaging force is satisfied, and examples thereof include a mushroom shape, a hook shape, a T shape, or a J shape.

The size of the hook material 22 can be determined based on various viewpoints, such as a reduction in sheet weight, maintenance of the engagement force with the second hook and loop fastener member, ease of detachment from the second hook and loop fastener member, and production costs.

The lower limit of the thickness of the hook material 22 may be 60 μm, 90 μm, or 115 μm, and the upper limit thereof may be 600 μm, 550 μm, 500 μm, 350 μm, 320 μm, or 300 μm. The bulkiness of the sheet 1A fixed to the support surface 90 can be suppressed by such a reduction in the thickness of the hook material 22. When the hook material 22 is used as the first hook and loop fastener member, the sheet 1A is thin and light. Therefore, the flexibility of the sheet 1A can be ensured, and the portability and operability of the sheet 1A can be further enhanced.

The lower limit of the thickness of the substrate 22a may be 20 μm, 30 μm, or 35 μm, and the upper limit of the thickness may be 100 μm, 80 μm, 70 μm, or 60 μm. The lower limit of the height of the hook 22b may be 40 μm, 60 μm, or 80 μm, and the upper limit of the height may be 500 μm, 400 μm, 300 μm, 280 μm, or 260 μm.

When the hook 22b has a mushroom shape, the maximum width and the minimum width of the shank portion (bow handle) are not limited. For example, the lower limit of the maximum width of the shank portion may be 70 μm or 100 μm, and the upper limit may be 250 μm, 200 μm, or 190 μm. The lower limit of the minimum width of the shank portion may be 50 μm or 80 μm, and the upper limit thereof may be 210 μm, 200 μm, 195 μm, or 185 μm. The maximum width of the parasol portion (cover) is not limited, and the lower limit may be 70 μm, 100 μm, or 200 μm, and the upper limit may be 500 μm, 450 μm, 400 μm, 350 μm, or 300 μm. The lower limit of the projection portion of the parasol starting from the tip end of the crotch portion may be 5 μm or 10 μm, and the upper limit may be 90 μm, 85 μm, 80 μm, or 75 μm.

Regardless of the type and material of the hook material 22, the mating surface of the hook material 22 can have a region that does not include the hook 22b. In the present disclosure, the area not including the hook is referred to as a "hook-free region" for the sake of convenience. The area of the hookless area is relative The ratio of the total area of the hook material 22 can be determined based on various viewpoints, such as maintenance of the engagement force with the second hook and loop fastener member, ease of detachment from the second hook and loop fastener member, and production cost. For example, the lower limit of the ratio may be 5%, 10%, 15%, 20%, 25%, or 30, and the upper limit may be 50%, 45%, 40%, 35%, or 30%. The shape and configuration of the hookless area are not limited. For example, the hookless regions may be configured in the form of a plurality of lines extending parallel to each other, may be arranged in a lattice form, may be distributed regularly or irregularly, or may be randomly arranged.

(Eighth embodiment)

As described above, a kit for a sheet of material comprising a sheet and a second hook and loop fastener member can be provided in accordance with an embodiment of the present disclosure. The kit for a sheet may further include an adhesive layer having a low adhesiveness and provided between the second hook and loop fastener member and a support surface. In the eighth embodiment, a set of sheets for a sheet having an adhesive sheet containing a low-adhesive adhesive layer is described.

It is often the case that the second hook and loop fastener member secured to a support surface must be removed after use. However, when the support surface is a wall on which a polyvinyl chloride foam material or the like wallpaper is adhered, the support surface is very easily damaged. Therefore, when the second hook and loop fastener is peeled off, the wallpaper is often peeled off together, and the wall is often damaged. The eighth embodiment relates to a structure for a set of a sheet material, the set having an adhesive sheet comprising an adhesive layer having a low adhesiveness, the adhesive layer allowing The second hook and loop fastener member is peeled off without damaging the easily damaged support surface.

A kit 100 for a sheet according to the eighth embodiment includes: a sheet 1; a hook material 22 which is a second hook and loop fastener member; and an adhesive sheet 40 which includes a low adhesiveness Adhesive layer 40b. Figure 13 is a diagram showing an example of one of the structures of a kit 100 for a sheet.

An adhesive layer 40b having a low adhesiveness can be provided on one side of the second hook and loop fastener member that is in contact with the support surface 90. "Low tackiness" indicates that when the adhesive layer 40b is peeled off from the support surface 90, the support surface 90 is not damaged by the adhesive sheet 40, that is, indicated on the support surface 90 and the adhesive sheet. The low adhesion strength of 40 degrees of peeling together.

The adhesive sheet 40 includes: a base material layer 40a; an adhesive layer 40b having a low adhesiveness and provided on the first main surface of the base material layer 40a; and an adhesive layer 40c provided on the base material layer 40a The second main face. When the kit 100 for sheets is used, the adhesive layer 40b is in contact with the support surface 90. The hook material 22 is fixed to the adhesive layer 40c.

The material of the base material layer 40a is not limited. For example, the base material layer 40a may be polyethylene terephthalate (PET), polyurethane, ethylene vinyl acetate (EVA), polyethylene (unoriented), oriented polypropylene (OPP), paper. Made of wood or fabric.

The material of the adhesive layer 40b is not limited. For example, the adhesive layer 40b may be formed of an acrylic-based, rubber-based, or polyoxyl-based adhesive. Among them, the polyoxymethylene-based adhesive exhibits low adhesion strength, and the necessary retention characteristics can be achieved by high wettability, although the adhesion strength is low. Therefore, by forming the adhesive layer 40b using a polyoxygen-based adhesive, the adhesive sheet 40 can be peeled off from the support surface 90 without damaging the support surface 90.

An example of a method of manufacturing the adhesive sheet 40 is described. For example, to make the adhesive sheet 40, a water-based polyether urethane primer or a solvent-based polyether urethane primer is used as a primer. As a water-based polyether urethane primer, HYDRAN WLI-602 (available from DIC Corporation) was diluted to a concentration of 10 wt.% using ultrapure water for use. As a solvent-based polyether urethane primer, polyurethane 8552 (available from Arakawa Chemical Industries, Ltd.) was diluted to a concentration of 10 wt.% using methyl ethyl ketone for use.

As the material of the adhesive layer 40b, PDMS having a functional group at the terminal or having no functional group at the terminal (such as PDMS described in US Pat. No. 8,541,481) and a polyoxyxylene resin having an MQ structure are used. As an example, TSF451-100M (available from Momentive Performance Materials Japan LLC) can be used as a top three The thiol ethyl group is used as the terminal PDMS, and MQ803TF (commercially available from Wacker Chemie AG) can be used as the polyoxynoxy resin having the MQ structure.

For example, a polyoxynoxy adhesive is prepared by dissolving 30 parts by weight of a polyoxyxylene resin in 100 parts by weight of PDMS having a trimethylsulfonylethyl group as a terminal. The adhesive layer 40b is produced by applying a polyoxyxylene adhesive to the substrate layer 40a to which the primer has been applied. As an example, the thickness of the adhesive layer 40b is 50 μm. The adhesive layer 40b which has been applied on the substrate layer 40a is cured by electron beam irradiation (40 kGy; acceleration voltage: 210 KeV).

The material of the adhesive layer 40b, the material of the base material layer 40a, and the method of manufacturing the above-described adhesive sheet 40 are examples. The adhesive layer 40b and the substrate layer 40a can be manufactured by using other materials or other manufacturing methods.

The material of the adhesive layer 40c is not limited. For example, a pressure sensitive adhesive or a heat sensitive adhesive can be used as the adhesive layer 40c. The structure of the adhesive layer 40c may be the same or different from the above-described adhesive layer 13.

It should be noted that the eighth embodiment describes a kit 100 for a sheet comprising a hook material 22 and an adhesive sheet 40, the hook material being a second hook and loop fastener member; however, having a low adhesiveness Adhesive layer 40b can be provided on the back side of hook material 22, which is a second hook and loop fastener member. That is, it is not necessary to use the adhesive sheet 40 including the base material layer 40a.

The shape and size of the adhesive sheet 40 can be such that the entirety of the second hook and loop fastener member is positioned on the substrate layer 40a and the adhesive sheet 40 is at least a portion of the outer side of the circumference around the second hook and loop fastener member. The mode of extension is set. E.g, The shape and size of the adhesive sheet 40 can be set in such a manner that the adhesive sheet 40 extends in the outer side around the entire circumference of the second hook and loop fastener member. By manufacturing the adhesive sheet 40 in this manner, the adhesive sheet 40 to which the second hook and loop fastener member is adhered can be easily peeled off from the support surface 90.

FIG. 14 illustrates an example of use of the kit 100 for sheets. The operator adheres the adhesive sheet 40 to the support surface 90 in a state where the adhesive layer 40b of the adhesive sheet 40 faces the support surface 90. By this operation, the hook material 22 adhered to the base material layer 40a of the adhesive sheet 40 is fixed to the support surface 90. It should be noted that the hook material 22 may not be adhered to the adhesive sheet 40 in advance, and in this case, the operator may adhere the hook material 22 to the adhesive sheet 40. After the operator adheres the sheet 1 to the hook material 22 on the support surface 90, the sheet 1 can be adhered to the support surface 90. As described above, the operator can detach the sheet 1 from the hook material 22.

When the hook material 22 is detached from the support surface 90, the operator needs to peel the adhesive sheet 40 from the support surface 90. Thereby, the kit 100 for the sheet can be detached from the support surface 90 without damaging the support surface 90.

The structure for the kit of sheets is not limited to this embodiment. For example, a kit for a sheet may include: a sheet 1A; a loop material 21 which is a second hook and loop fastener member; and an adhesive sheet 40. Adhesive layer 40c may not be an assembly of adhesive sheets, but may be an assembly of second hook and loop fastener members.

In this aspect, since a hook and loop fastener member is provided on the back side of the film layer, the sheet can be easily attached or detached. For example, even when wrinkles or deliquescence occurs on the sheet during initial adhesion of the sheet to the support surface, the operator can temporarily peel off a portion or the entirety of the sheet and then adhere the sheet again. Since the sheet can be repeatedly attached and detached, the sheet can be posted by a small number of operators. In addition, it is also possible to reuse it easily, such as adhering a piece of material adhered to one place to another.

By setting the thickness of the hook material to 600 μm or less, the bulkiness of the sheet fixed on the support surface can be suppressed. When the hook material is used as the first hook and loop fastener member, the sheet also becomes thin and light, because the hook and loop fastener member becomes thin and light. Therefore, the portability and operability of the sheet can be further enhanced.

In a sheet according to another aspect, the 90° peel adhesion strength relative to one of the second hook and loop fastener members engageable with the first hook and loop fastener member may be from 0.5 N/25.4 mm to 8 N/ 25.4mm. By setting the 90° peel adhesion strength of the sheet in this manner, the sheeting force can be maintained while the sheet is being stretched, and at the same time, the sheet can be easily detached.

In a sheet according to another aspect, the film layer may comprise a support layer comprising polyester. With this structure, the strength of the film layer and the sheet can be enhanced.

In a sheet according to another aspect, the first hook and loop fastener member can be secured to the entirety of the back side of the film. By providing the first hook and loop fastener structure in this way The operator can easily adhere the sheet to the support surface without rigorous attention to the positional relationship of the second hook and loop fastener member provided on the support surface of the sheet.

In a sheet according to another aspect, the mating face of the loop material may have a region that does not include a loop. By providing this region, the sheet can be easily unloaded by suppressing the peeling adhesive strength of the sheet. In addition, the sheet can be reliably adhered to the support surface while avoiding or inhibiting a phenomenon in which a portion of the loop layer is peeled off and transferred to the second hook and loop fastener member (such as hook material) during sheet detachment (ie, Transfer).

In a sheet according to another aspect, the film layer is a printed film layer, and the sheet can be used as a graphic sheet. In this case, the graphic sheet can be easily attached or detached. In addition, easy reuse of graphic sheets is also possible.

In a sheet according to another aspect, the first hook and loop fastener member can be engaged with a second hook and loop fastener member that is secured to the garment or fabric. In this case, the graphic sheet can be easily attached to or detached from the garment or fabric. In addition, easy reuse of graphic sheets is also possible.
