Description

  The present invention relates to a flooring material such as a carpet to which a release sheet is attached.

Conventionally, various floor materials are laid on the floor of a building.
Of the flooring, the carpet is, for example, laid in a room, kitchen, entrance, bathroom entrance, hallway, and the like. Such a carpet is also called a mat or a rug.
In order to prevent slippage and slippage of the carpet, it is known that a laying sheet provided with an adhesion portion such as a peel-up adhesive is interposed between the floor surface and the carpet as shown in Patent Document 1. Yes. There is also known a carpet in which an adhesion portion is directly provided on the back surface.
When the carpet having the attachment portion on the back surface is laid on the floor surface, the attachment portion is sufficiently adhered to the floor surface, so that the carpet can be prevented from being displaced or slipped.

For carpets with such attachments on the back, if they are rolled up and stored, or if a plurality of them are stacked and stored, the attachment part of the upper carpet will adhere to the surface of the lower carpet. There is a problem of causing blocking. In addition, blocking is in the state in which a plurality of sheet-like materials are stacked, and overlapping sheets adhere to each other.
In this regard, as in Patent Document 1, by attaching a release sheet so as to cover the adhesion portion on the back surface of the carpet, the carpet can be wound in a roll shape or stacked in a plurality.

  Such a release sheet is peeled off when the carpet is used. However, since the carpet with the release sheet stored in a roll or stacked is pressed in the thickness direction of the carpet, the release sheet is peeled off. There is a problem that it is difficult.

Specifically, the flooring 1 with a release sheet may be long or single-wafer. The floor material 1 with a long release sheet has an elongated rectangular shape in plan view, and is usually stored and transported in a roll shape. The width and length of the long release flooring with a release sheet 1 are appropriately designed. For example, the width is 300 mm to 3000 mm, preferably 300 mm to 2000 mm, and the length is 1 m to 10 m, preferably Is 1 m to 4 m in length. The sheet material-like flooring with release sheet 1 is usually stored and transported by stacking a plurality thereof. The planar view shape of the floor material 1 with a sheet-like release sheet is not particularly limited, and examples thereof include a rectangular shape such as a rectangle or a square, a circular shape, and an elliptical shape. The length and width of the sheet-like floor sheet 1 with a release sheet having a rectangular shape in plan view are appropriately designed. For example, the length is 300 mm to 1000 mm, and the width is 300 mm to 1000 m.
In addition, in the example of illustration, the floor material 1 with a sheet-like release sheet is illustrated for convenience.

In the present invention, a conventionally known material can be used as the flooring 2 (flooring body 4). Examples of the flooring 2 (flooring body 4) include carpets, rubber or soft or hard synthetic resin flooring sheets, and wooden flooring provided with a wooden material such as bamboo, rattan or cork on the surface. In the drawing, a carpet is illustrated as the flooring 2.
2 and 4, the floor material body 4 constituting the carpet is laminated on, for example, a base cloth 41, a pile 42 protruding from the upper surface of the base cloth 41 and tufted to the base cloth 41, and the back surface of the base cloth 41. A backing layer 43, an adhesive layer 44 laminated on the back surface of the backing layer 43, and a backing layer 45 laminated on the back surface of the adhesive layer 44.
An adhesion portion 5 is provided on the back surface of the backing layer 45.

The base cloth 41 is provided for tufting the pile 42. The base fabric 41 is not specifically limited, For example, a nonwoven fabric, a woven fabric, a knitted fabric etc. are mentioned, Among these, it is preferable to use a nonwoven fabric. The base fabric 41 may be coated with a precoat agent such as SBR, MBR, PVC latex, and EVA.
The pile 42 may be a loop pile as illustrated or a cut pile (not shown). The material of the pile 42 is not particularly limited. For example, a known fiber processed yarn made of polyamide such as nylon, polyester, polypropylene, polyethylene, polyvinyl chloride, or the like can be used.
The backing layer 43 is provided to fix the tufted pile 42. The backing layer 43 is not particularly limited. For example, a synthetic resin such as polyvinyl chloride, urethane resin, ethylene-vinyl acetate copolymer, or SBR can be used, and among these, an ethylene-vinyl acetate copolymer is preferable.
The adhesive layer 44 is provided to adhere the backing layer 43 and the backing layer 45. However, when the backing layer 43 can sufficiently adhere to the backing layer 45, the adhesive layer 44 may be omitted, and the backing layer 45 may be provided directly on the back surface of the backing layer 43.
Examples of the backing layer 45 include nonwoven fabric, felt, woven fabric, rubber layer, synthetic resin layer, foamed resin layer, nonwoven fabric or woven fabric impregnated with resin or rubber. In addition, it is preferable to use felt as the backing layer 45 when cushioning is imparted to the flooring 2. Examples of the felt include polyester felt, polypropylene felt, nylon felt, needle punching felt, wool felt, etc. Among them, polyester felt is preferable because of excellent durability and flexibility. The resin component of the synthetic resin layer and the foamed resin layer is not particularly limited, and examples thereof include acrylic resin such as polyvinyl chloride, polyolefin, ethylene-vinyl acetate copolymer, ethylene-methacrylate resin, and polyester.
Moreover, it may replace with the pile 42, the base fabric 41, and the backing layer 43, and the flooring main body 4 using the nonwoven fabric obtained by a needle punch method etc. may be sufficient. The floor material body 4 is provided with an adhesive layer 44 and a backing layer 45 on the back surface of the nonwoven fabric such as the needle punch.

An adhesion portion 5 is provided on the back surface of the backing layer 45.
The adhering portion 5 includes a plurality of convex portions protruding from the back surface of the backing layer 45.
In addition, in order to illustrate the formation range of the adhesion part 5 in an easy-to-understand manner, in FIG. 3, for convenience, the adhesion part 5 is shaded.
The adhesion part 5 is provided in order to make the flooring 2 difficult to slide with respect to the floor surface. The floor surface is a place where the flooring 2 is laid.
The adhering portion 5 is not particularly limited as long as the adhering portion 5 can adhere to the flooring material with sufficient adhesion to prevent the flooring 2 from slipping. Examples of the material for forming the attachment portion 5 include materials that adhere to the floor surface by adsorption or adhesion. The adhering part 5 by adsorption strongly adheres to the floor surface when a load is applied to the laid flooring 2, so that the flooring 2 can be prevented from being displaced, and on the other hand, when the load is not applied to the flooring On the other hand, since it adheres weakly, the flooring 2 can be removed relatively easily. If the adhering part 5 by adsorption is used, the release sheet 3 attached to the adhering part 5 adheres strongly to the adhering part 5 during the storage of the flooring 1 and is difficult to peel off. It can be easily peeled off. For this reason, in the flooring 1 with a release sheet of this invention, the thing to which the adhesion part 5 adheres by adsorption | suction is preferable.
For example, examples of the material for forming the attachment portion 5 attached by the adsorption include flexible foamed resin and soft rubber. Examples of a material for forming the attachment portion 5 attached by the adhesion include a peel-up adhesive. In particular, as a material for forming the adhesion part 5, a foamed resin having flexibility is preferable.
The flexible foamed resin has a porous structure having a plurality of micropores on the back surface. The foamed resin may have either an open-cell structure or a closed-cell structure, but an open-cell structure is preferable because it has a sufficient suction cup function and exhibits a high adsorption force. The material of the foamed resin is not particularly limited, and examples thereof include thermoplastic resins such as acrylic resin, urethane resin, ethylene-vinyl acetate, polyvinyl alcohol, polyvinyl acetate, epoxy resin, acrylic ester, and polyester. Since the adhesiveness is excellent, it is preferable to use a foamed acrylic resin obtained by foaming an acrylic resin as a material for forming the adhesion portion 5. The expansion ratio of the foamed resin is not particularly limited, but is preferably 1.1 to 6 times, more preferably 1.6 to 2 times, and particularly preferably 1.6 to 2 times. If the expansion ratio is too low, the adsorptive power becomes weak, and if it is too high, the adhering portion 5 becomes brittle, which may cause material destruction.

In the illustrated example, the adhering portion 5 is not provided on the entire back surface of the floor material body 4, but is provided partially on the back surface of the floor material body 4. That is, as for the back surface of the flooring 2, the back surface of the adhesion part 5 and the back surface of the flooring main body 4 are exposed. This adhesion part 5 consists of a several convex part of planar view belt shape. Each belt-like convex portion extends from the first edge 4a of the floor material body 4 to the second edge 4b on the opposite side. Each belt-like convex part is formed in parallel with a required interval between the third edge 4c and the fourth edge 4d on the opposite side. Since the belt-like convex portions are formed in parallel, the left end convex portion 5 c is disposed in the vicinity of the third edge 4 c of the flooring main body 4, and the right end convex portion 5 d is the fourth convexity of the flooring main body 4. It is arranged in the vicinity of the edge 4d. The left end convex portion 4 c may be arranged so that the side edge thereof coincides with the third edge 4 c of the floor material body 4. The right end convex portion 5d may be arranged such that the side edge thereof coincides with the fourth edge 4d of the floor material body 4. However, in order to make it easier for the release sheet 3 to roll from the edge of the floor material body 4, the convex portions 5 c and 5 d are preferably disposed in the vicinity of the edge of the floor material body 4.
The cross-sectional shape of the convex portion is not particularly limited, and is usually formed in a semicircular arc shape, a substantially rectangular shape, or a substantially triangular shape. When the flooring 2 is laid, it deforms uniformly and adheres well to the floor surface, so that the cross-sectional shape of the convex portion is preferably a semicircular arc shape. The cross-sectional shapes of the plurality of convex portions may all be the same, or the cross-sectional shapes of some of the convex portions may be different.

The height H of the convex portion is not particularly limited, but if it is too small, the effect of preventing the displacement of the flooring 2 may not be obtained, and is, for example, 0.1 mm to 2 mm, preferably 0.2 mm. ~ 0.5 mm. The height H of the convex portion is a linear length from the back surface of the backing layer 45 to the apex of the convex portion (the straight line is perpendicular to the back surface of the backing layer 45).
The width W1 of the convex portion is not particularly limited. However, if it is too small, there is a possibility that the displacement or slippage of the flooring 2 cannot be prevented. May be difficult to remove from the floor. From such a viewpoint, the width W1 of the convex portion is preferably 1 mm to 10 mm, and more preferably 1.5 mm to 8 mm. In addition, when the planar view shape of the said convex part is strip | belt shape, and the width | variety is not uniform, the width W1 of the said convex part corresponds to the width | variety in the largest location. Similarly, in the case where the shape of the convex portion in plan view is another shape such as a dot shape, it is the width at the largest location.
The interval W2 between adjacent convex portions is not particularly limited, but if it is too small, it may be difficult to remove the laid flooring 2 from the floor surface, and if it is too large, it may not be possible to prevent displacement or slippage of the flooring 2. There is. From such a viewpoint, the interval W2 between adjacent convex portions is preferably 5 mm to 35 mm, more preferably 10 mm to 25 mm, and particularly preferably 15 mm to 25 mm. The intervals W2 between the convex portions may be different or the same. The distance W2 between the convex portions is preferably the same because it is in close contact with the floor surface.
When the interval W2 between the convex portions is set in the above range, the vicinity includes the interval between the side edges of the third edge 4c and the convex portion 5c and the interval between the side edges of the fourth edge 4d and the convex portion 5d. Is 5 mm or less, preferably 3 mm or less.

An overlock process is applied to the peripheral edge of the floor material body 4 as an overburden process. The peripheral part of the flooring main body 4 includes a first edge part (an edge part including the first edge 4a; hereinafter the same), a second edge part, a third edge part, and a fourth edge part of the flooring body body 4. A part of the adhesion portion 5 is included in the peripheral portion subjected to the overlock process. That is, an overlock process is applied to the peripheral edge portion including the adhering portion 5 of the floor material body 4.
The overlock process is edge stitching using an overlock thread 6 in order to prevent the edge of the floor material body 4 from being unwound. Examples of the stitches by the overlock process include one-needle three-thread, one-needle two-thread, two-needle four-thread, and M stitch. The overlock process can be performed using a known overlock sewing machine. The stitch interval of the overlock process is not particularly limited, and is, for example, 5 to 30 stitches / inch, preferably 14 to 18 stitches / inch.
The overlock yarn 6 is not particularly limited, and any of synthetic fiber, semi-synthetic fiber, and natural fiber may be used. Since it is excellent in strength, it is preferable to use a synthetic fiber made of polyamide resin, polyester resin, polypropylene resin, mixed resin or the like. The synthetic fiber may be a single type or a composite yarn using two or more types in combination.
The thickness of the overlock yarn 6 is not particularly limited, but if it is too small, the entire overlock yarn 6 may be buried in the flexible adhering portion 5 and the overlock yarn 6 may not come into contact with the release sheet 3. If the edge strength is low and too large, the peripheral edge of the flooring 2 may slightly float from the floor surface when the flooring 2 is laid, and it is difficult to perform overlock processing. From such a viewpoint, the thickness of the overlock yarn 6 is preferably 100d to 9000d, and more preferably 1000d to 3000d.

In the edge-over region where the overlock process is performed, the overlock yarn 6 is present on the back surface of the flooring 2 with a gap. The overlock yarn 6 does not exist in the adhesion region, and the adhesion portion 5 is exposed. As shown in FIG. 3, the adhesion region is surrounded by an edge region.
When the edged area is viewed from the back surface, it is composed of a portion where the back surface of the flooring 2 is exposed and the overlock yarn 6. In other words, on the back surface of the edged region, the back surface of the adhering portion 5 and the back surface of the backing layer 45 (the back surface of the flooring main body 4) are exposed between the overlock yarns 6. The edge overhanging region is a region between the edge of the flooring main body 4 and the tip 6a of the overlock yarn 6 (inner end of the overlock yarn 6). The width of the edge region in the present embodiment is not particularly limited, but is usually 5 mm to 20 mm. If the width of the edge area is too small, the release sheet 3 may be difficult to peel off from the peripheral edge. If the width is too large, the release sheet 3 may be rolled during manufacture, storage, and transportation. is there.

The release sheet 3 is attached across the adhesion area and the edge area.
In the present embodiment, the release sheet 3 is made of a sheet material that has been subjected to a release treatment on at least one surface. The release sheet 3 is a sheet having the same shape and the same size as the back surface of the flooring main body 4 and is attached over the entire adhesion area and the entire edge area. The release surface of the release sheet 3 adheres to the back surface of the adhesion portion 5 in the adhesion region, and adheres to the back surface of the adhesion portion 5 present in the exposed portion between the overlock yarns 6 in the edge region. ing. In the edge region, the overlock yarn 6 is partially interposed between the release sheet 3 and the flooring 2. For this reason, the release sheet 3 corresponding to the edge area includes a portion attached to the attaching portion 5 and a portion in contact with the back surface of the backing layer 45 and the overlock yarn 6.
The sheet material constituting the release sheet 3 is not particularly limited, and examples thereof include paper and a synthetic resin sheet. Among these, a synthetic resin sheet is preferable. The thickness of the sheet material is not particularly limited, and is, for example, 5 μm to 200 μm, preferably 5 μm to 100 μm, and more preferably 10 μm to 30 μm. If the thickness of the sheet material is too small, the sheet material may be inadvertently broken. If the thickness is too large, the rigidity becomes high and lacks flexibility, so that the release sheet 3 may be difficult to peel off. Examples of the mold release treatment include addition or application of silicone.
The release sheet 3 may be colorless and transparent, colored and transparent, or colored and non-transparent, but is preferably colorless and transparent or colored and transparent. The colored transparency includes what is called semi-transparency having a high haze value. By using the colorless transparent or colored transparent release sheet 3, in the flooring 1 with the release sheet, the configuration of the back surface of the flooring 2 through the release sheet 3 (for example, an adhesion portion provided on the backside of the flooring 2 5), it is convenient when distributing and using the flooring 1 with a release sheet.

The said flooring material 1 with a release sheet can be manufactured as follows, for example.
As shown in FIG. 5A, a living machine A is manufactured in which a base cloth 41 tufted with a pile 42 and a backing layer 43 are laminated. This living machine A is cut into a plan view shape of the flooring 1 with a release sheet to be manufactured.
On the other hand, the intermediate body B in which the release sheet 3 is attached to the backing layer 45 provided with the adhesion portion 5 is manufactured.
An adhesive layer 44 is interposed between the raw machine A and the intermediate body B to bond them together, and a laminated body in which the release sheet 3 is attached to the entire attachment portion 5 is manufactured. For example, as shown in FIG. 5A, the adhesive layer 44 is laminated on the surface of the intermediate B (the surface of the backing layer 45), and the living machine A is placed thereon. In addition, you may cut | disconnect the laminated body which bonded the raw machine A and the intermediate body B to the flooring material shape which is due to manufacture, without cutting at the stage of the raw machine A. Further, the living machine A may not have the backing layer 43.
Next, as shown in FIG. 5 (b), only the peripheral edge portion 3a of the release sheet 3 attached to the laminate C is peeled off from the adhesive portion 5, and overlock processing is performed on the peripheral edge portion of the laminate C ( Overlock thread not shown). After the overlock processing, the release sheet 3 is exposed from the gap of the overlock yarn in the edge area by returning the peripheral edge part 3a of the release sheet 3 to the back surface of the peripheral edge part (edge edge area) of the laminate C. It adheres to the attaching part 5 which does. Thus, the flooring 1 with a release sheet as shown in FIG.1 and FIG.2 can be obtained.

  In addition, in the manufacturing method of the flooring 1 with a release sheet, the case where the release sheet 3 attached in advance to the backing layer 45 is used as an example. It can be changed in various ways. For example, as shown in FIG. 3 and FIG. 4, after manufacturing the flooring 2 in which the adhesion part 5 is provided on the back surface of the backing layer 45 and the peripheral part is overlocked, the adhesion area of the flooring 2 is produced. In addition, the release sheet 3 may be attached across the edge region. Even in this way, a flooring 1 with a release sheet as shown in FIGS. 1 and 2 can be obtained.

The flooring 1 with a release sheet is stored and transported in a roll shape or a plurality of the flooring materials 1 depending on its shape.
When it rolls up or is piled up, the flooring 1 with a release sheet is pressurized in the thickness direction, so that the release sheet 3 strongly adheres to the attachment part 5. Since the release sheet 3 is attached over the edge area and the adhesion area, an overlock yarn is provided at some positions between the release sheet 3 and the adhesion area 5 at the edge of the release sheet 3. 6 is interposed. Since the overlock yarn 6 does not adhere to the release sheet 3, the flooring material 1 with the release sheet of the present invention can easily wind an arbitrary edge portion of the release sheet 3 and easily peels the release sheet 3. Can do.
After the release sheet 3 is peeled from the floor material 1 with the release sheet, the floor material 2 is laid on the floor surface. Since the flooring 2 has an edged region, the flooring 2 can be peeled off from the floor surface after laying, and can be easily changed or cleaned. When overlock processing or tape lock processing is used as the overburden processing, the release sheet 3 can be easily peeled off, and the design of the flooring 2 can be improved. In particular, when the flooring 2 is a carpet. Is preferable because it can prevent the fiber from being unraveled at the edge.

[Second Embodiment]
2nd Embodiment is related with the flooring with a release sheet by which the tape lock process is given to the peripheral part of a flooring main body as an overburden process. Hereinafter, in the description of the second embodiment, the same configurations and effects as those of the first embodiment will be omitted (assuming that the description has been made), and terms and symbols may be used.
In FIG.6 and FIG.7, the flooring material 1 with a release sheet of this embodiment also has the flooring 2 and the release sheet 3 attached to the back surface of the flooring 2. FIG. In addition, FIG. 8 is the figure which looked at flooring 2 (what remove | released the release sheet 3 from the flooring 1 with a release sheet of FIG.6 and FIG.7) from the back surface. In FIG. 6, countless dots are added to the release sheet 3 in order to illustrate the release sheet 3 in an easy-to-understand manner. Further, in FIG. 8, shading is added to the attachment portion 5 of the attachment region (not covered with the tape 7).
In the present embodiment, tape lock processing in which the tape 7 is attached to the peripheral edge portion of the flooring main body 4 is used as the edge processing. The release sheet 3 is attached so as to straddle the edge area where the tape lock processing is performed and the adhesion area where the adhesion portion 5 is exposed.

Specifically, the tape 7 folded in half is attached to the peripheral part of the flooring main body 4 so as to embrace the peripheral part. The area where the tape 7 is attached is the edge area. The width of the edge area in the present embodiment is not particularly limited, but is usually 1 mm to 10 mm.
The tape 7 is not particularly limited, and examples thereof include cloth tape and synthetic resin sheet tape. As the thread of the cloth tape, synthetic resin fibers such as polyester resin, polyamide resin, and polyolefin resin, or natural fibers can be used. If necessary, makeup such as pattern printing or embroidery may be applied to the tape 7. By using such a tape with makeup, the design of the flooring 2 can be enhanced.
The thickness of the tape 7 is not specifically limited, For example, it is 0.1 mm-2 mm.
The method for attaching the tape 7 to the peripheral portion of the flooring main body 4 is not particularly limited. For example, the method of attaching the tape 7 to the peripheral portion of the flooring main body 4 using an adhesive or the tape 7 using a sewing thread. The method of sewing to the peripheral part of the flooring main body 4 is mentioned. These methods may be used alone or in combination.
In particular, when a wide tape 7 is used, for example, an adhesive such as a hot-melt adhesive is interposed between the back surface of the peripheral edge of the floor material body 4 and the tape 7 so that the tape 7 is attached to the peripheral edge of the floor material body 4. While adhering to the back of the part, the tape 7 may be sewn using a sewing thread and fixed to the flooring main body 4.
Since the release sheet 3 is also attached across the marginal area and the adhesion area, the release sheet 3 can be easily peeled off in the flooring material 1 with the release sheet of the present embodiment.

[Other Embodiments]
The flooring 1 with a release sheet of the present invention is not limited to the first and second embodiments, and can be variously changed within the range intended by the present invention.
For example, in the first and second embodiments, the release sheet 3 is attached to the entire back surface of the flooring 2 (the entire edge area and the entire adhesion area). It may be attached across a part of the overburden region and the adhesion region. In the example shown in FIG. 9, the release sheet 3 is attached to the adhesion area and the edge area of the floor material 2 except for the edge area corresponding to the third edge of the floor material 2. That is, the release sheet 3 is attached to the entire edge overhang region and the adhesion region corresponding to the first edge, the second edge, and the fourth edge of the flooring 2. In FIG. 9, in order to illustrate the release sheet 3 in an easy-to-understand manner, countless dots are added to the release sheet 3, and further, a shade is added to the adhesion part 5 that is not covered with the release sheet 3. Yes. In the edge area, a part of the adhering portion 5 is covered with the overlock yarn 6 and the adhering portion 5 is not provided on the entire back surface of the flooring 2. Therefore, the adhering force is smaller than the adhering region. . For this reason, even the flooring 1 with a release sheet in which the release sheet 3 is not attached to a part of the edge area as shown in FIG. 9 can suppress blocking when it is rolled or stacked. In the flooring 1 with a release sheet of the present invention, it is sufficient that the release sheet 3 is attached across at least a part of the edge area and the adhesion area.
