Description

[Technical Field]

[0001] The present invention relates to a comforter and a comforter cover. [Background technology]

[0002] When using a quilt with a cover, the quilt may shift position inside the cover. For this reason, for example, a quilt cover as described in Patent Document 1 has been proposed. The quilt cover described in Patent Document 1 is made by sewing together an outer fabric and an inner fabric into a bag shape, has an opening for inserting and removing the quilt, and has tie strings inside for tying the quilt to the quilt. Multiple tie strings are provided around the periphery of the quilt cover.

[0003] Patent Document 2 also proposes a quilt cover that does not use tie strings. This quilt cover has a rectangular opening formed along the periphery of the top surface of the cover body, with right-angled triangular pieces of fabric sewn to each corner of the opening. The oblique ends of each piece of fabric are overlapped, and a diamond-shaped or rectangular insertion / removal hole for the quilt is formed in the center of the oblique sides of each piece of fabric. Elastic material is attached to each oblique side, allowing the oblique sides to stretch freely. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3199806 [Patent Document 2] Japanese Utility Model Application Publication No. 7-30835 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when attaching the duvet cover of Patent Document 1 to a duvet, the tying strings must be tied to the duvet, which is time-consuming. Furthermore, the tying strings are located away from the opening of the duvet cover, making it difficult to reach from the opening, making it difficult to tie the tying strings to the duvet.

[0006] Furthermore, in the duvet cover of Patent Document 2, elastic material is provided on the oblique side of the cloth piece that forms the insertion / removal hole to bring the internal duvet into close contact with the duvet cover and prevent it from shifting out of position. However, simply providing elastic material is not enough to bring the duvet into close contact with the duvet cover, and it is not possible to sufficiently prevent it from shifting out of position.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a comforter and a bedding cover that can be easily attached to comforters such as quilts and that can prevent them from shifting out of position. [Means for solving the problem]

[0019] (First embodiment) An embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of a comforter 10 according to an embodiment of the present invention, and Fig. 2 is a plan view of the comforter 10. Fig. 3 is a cross-sectional view of the comforter 10 housed in a known bedding cover 100.

[0020] The comforter 10 includes items such as a quilt, a blanket, etc. that are used to cover the body when sleeping. The comforter 10 is rectangular, and the following description will use as an example a single-size comforter with a width L11 of 150 cm and a length L12 of 210 cm.

[0021] The comforter 10 of this embodiment is not limited to single size and may be any size, for example, a semi-double size with a width L11 of 170 cm, a double size of 190 cm, a queen size of 210 cm, or a king size of 230 cm. In most cases, the length L12 of any size is 210 cm.

[0022] As shown in Figure 3, the comforter 10 is made by sewing together the peripheries of a front fabric 13 and a back fabric 14, and filling the internal space with a filler material 15. The outer surfaces of the comforter 10, i.e., the upper and lower surfaces in Figure 3, are called the front surface 11 and the back surface 12. The comforter 10 can be used with either the front surface 11 or the back surface 12 facing up, and there is no difference in use between the front surface 11 and the back surface 12.

[0023] (Anti-slip area 30) The comforter bedding 10 has a non-slip area 30 on at least one of the front surface 11 and the back surface 12. In other words, the non-slip area 30 forms at least a portion of the front surface 11 and / or the back surface 12 of the comforter bedding 10. The non-slip area 30 has a friction coefficient of 0.8 or more, more preferably 0.91 or more. The friction coefficient is preferably set as large as possible to prevent misalignment between the comforter bedding 10 and the bedding cover 100. The friction coefficient is defined in JIS P8147:2010, and the friction coefficient of the non-slip area 30 is determined by a measurement method that mutatis mutandis applies to JIS P8147:2010. JISP8147:2010 defines the static and dynamic friction coefficients. "A friction coefficient of 0.8 or more" means that either the static or dynamic friction coefficient is 0.8 or more. Preferably, both the static and dynamic friction coefficients are 0.8 or more.

[0024] In this embodiment, the non-slip area 30 is made of a fabric having a non-slip function. The fabric constituting the non-slip area 30 is overlapped and sewn onto the outer surfaces of the front fabric 13 and the back fabric 14 of the comforter bedding 10 to form the front surface 11 and the back surface 12 of the comforter bedding 10.

[0025] The fabric constituting the non-slip area 30 can be any fabric as long as it has a coefficient of friction of 0.8 or higher. For example, the fabric constituting the non-slip area 30 is a tricot knit fabric, with a yarn composition of 61% polyester and 39% spandex (polyurethane elastic fiber) and a basis weight of 79 gsm (gsm: weight per square meter (g)). Alternatively, the fabric constituting the non-slip area 30 may be a woven or knitted fabric with a non-slip surface treatment such as polyurethane coating (PU coating). Alternatively, a raised fabric such as suede may be used. The thickness of the non-slip area 30 is preferably as thin as possible and maintains a coefficient of friction of 0.8 or higher so that the user does not notice the presence of the non-slip area 30 when the comforter bedding 10 is placed inside the bedding cover 100 (FIG. 3). Specifically, a thickness of 3 mm or less is preferred, 2 mm or less is more preferred, and 1 mm or less is even more preferred.

[0026] In this embodiment, the front surface 11 and back surface 12 of the duvet 10 are formed by overlapping the outer fabric 13, the lining 14 and the fabric that makes up the non-slip area 30, but this is not limited to this, and the front surface 11 and back surface 12 of the duvet 10 may also be formed by sewing the outer fabric 13, the lining 14 and the fabric that makes up the non-slip area 30 together in a flat pattern.

[0027] The front surface 11 and back surface 12 of the comforter bedding 10 may each be made of a single piece of fabric, at least a portion of which constitutes the non-slip area 30, and the threads constituting the fabric of the non-slip area 30 may have a non-slip function. In this case, polyurethane-based threads may be used, such as Lycra manufactured by Toray Opelontex Co., Ltd. or Leica manufactured by Asahi Kasei Corporation.

[0028] The non-slip area 30 may also be formed by applying a coating agent having a non-slip effect to the surfaces of the outer fabric 13 and the inner fabric 14. For example, hydrogenated styrene-based thermoplastic elastomer (SEBS) Tuftec or SOE manufactured by Asahi Chemical Synthetic Co., Ltd. is used as the coating agent. Furthermore, the non-slip area 30 may also be formed by laminating a film material having a non-slip effect onto the surfaces of the outer fabric 13 and the inner fabric 14.

[0029] (Arrangement of anti-slip area 30) Arrangements A to F will be described as examples of arrangement patterns of the non-slip areas 30 provided on the front surface 11 of the comforter 10. Note that the back surface 12 of the comforter 10 may also be provided with the non-slip areas 30.

[0030] In arrangement A, the anti-slip areas 30 have a strip-like shape when viewed from above. The length of the anti-slip areas 30 is aligned with the width of the comforter 10, and they are provided at a distance from each other at the center of the comforter 10 and on both sides of the center.

[0031] Arrangement A includes, for example, arrangement A1 shown in Figures 1 and 2 and arrangement A2 shown in Figure 4. In arrangement A1, the surface 11 of the comforter 10 has three non-slip areas 30A to 30C (hereinafter simply referred to as "non-slip areas 30" when not distinguishing between them). Each of the non-slip areas 30A to 30C has the same strip-like shape when viewed from above. The non-slip area 30A is located in the center of the comforter 10 in the longitudinal direction, and the non-slip areas 30B and 30C are located along both longitudinal edges of the comforter 10, sandwiching the center. There is a gap between adjacent non-slip areas 30A to 30C, and the areas between adjacent non-slip areas 30A to 30C are formed by the outer fabric 13 or inner fabric 14 of the comforter 10.

[0032] The length L1 of the strip-shaped non-slip area 30 is the same as the widthwise length L11 of the comforter 10. In other words, the non-slip area 30 is provided over the entire widthwise length of the comforter 10.

[0033] In this specification, "the anti-slip area 30 is provided over the entire width of the comforter 10" means not only that the anti-slip area 30 extends over the entire width between one end edge and the other end edge of the comforter 10, but also that the longitudinal edge of the anti-slip area 30 is located slightly inward (by a length of 10% or less of the width length L11) from one end edge and the other end edge.

[0034] The width L2 of each anti-slip area 30 is set according to the ratio of the area of ​​the anti-slip area 30 to the area of ​​the front surface 11 or the back surface 12 of the comforter 10, which will be described later.

[0035] As another example of arrangement A, arrangement A2 is shown in Figure 4. In the following explanation of arrangements A2 and B to F, only the configurations that are different from arrangement A1 will be explained, and the explanation of the same configurations will be omitted. In arrangement A2, the anti-slip areas 30B and 30C are located on either side of the center of the comforter 10, longitudinally inward from the both longitudinal edges of the comforter 10. The distance between the longitudinal edges of the comforter 10 and the anti-slip areas 30B and 30C is preferably 3% or less of the length L12 of the comforter 10 in the longitudinal direction, and in this embodiment is set to 4.2 cm, which is 2%.

[0036] An example of arrangement B is shown in Figure 5. In arrangement B, the anti-slip areas 30A to 30C have a band-like shape when viewed from above, and are provided along the length of the comforter 10 at the center in the width direction of the comforter 10 and on both sides of the center in the width direction, with a gap between them.

[0037] 5, the anti-slip area 30A is provided in the center of the comforter 10 in the width direction, and the anti-slip areas 30B and 30C are provided on either side of the center, along both widthwise edges of the comforter 10. The length L1 of the strip-shaped anti-slip area 30 is the same as the length L12 of the comforter 10 in the longitudinal direction. In other words, the anti-slip area 30 is provided over the entire length of the comforter 10 in the longitudinal direction.

[0038] "The non-slip area 30 is provided over the entire length of the comforter 10" means that the non-slip area 30 extends all the way between one end edge and the other end edge of the comforter 10 in the length direction, as well as the case where the end edges of the non-slip area 30 in the length direction are located slightly inward (by a length of 10% or less of the length L12 in the length direction) from one end edge to the other end edge.

[0039] In addition, in arrangements A1, A2, and B, three anti-slip areas 30A to 30C are provided, but one or more additional anti-slip areas 30 may be provided between anti-slip areas 30A and 30B, or between anti-slip areas 30A and 30C.

[0040] An example of arrangement C is shown in Figure 6. In arrangement C, the anti-slip areas 30B and 30C have a strip-like shape when viewed from above, and are provided on both sides of the length of the comforter 10 along the width of the comforter 10. In other words, this is arrangement A1 without the anti-slip area 30A.

[0041] An example of arrangement D is shown in Figure 7. In arrangement D, the anti-slip areas 30B and 30C have a strip-like shape when viewed from above, and are provided in pairs on both sides of the length of the comforter 10 along the width of the comforter 10. In other words, this is arrangement B without the anti-slip area 30A.

[0042] As shown in Figure 8, in arrangement E, the anti-slip area 30 has a band-like shape when viewed from above, and is provided in a ring shape along the peripheral edge (edges in the width and length directions) of the comforter bedding 10.

[0043] 9, in arrangement F, the anti-slip area 30 has a rectangular shape when viewed from above, and is provided at least in the center of the comforter 10. In the example shown in FIG. 9, the anti-slip area 30 is provided over the entire surface of the comforter 10.

[0044] In Figure 9, the anti-slip area 30 is provided over the entire surface 11 of the comforter 10, but it may be similar in shape to the surface 11 or back surface 12 of the comforter 10 and smaller in size than the comforter 10. In this case, the anti-slip area 30 is located in the center of the comforter 10, and the outer fabric 13 or inner fabric 14 is exposed around the anti-slip area 30.

[0045] The anti-slip area 30 is arranged on at least one of the front surface 11 and the back surface 12 of the comforter 10 in any of the arrangements A to F above. That is, it may be arranged on either the front surface 11 or the back surface 12 of the comforter 10, or on both the front surface 11 and the back surface 12 of the comforter 10. When it is arranged on both surfaces, the arrangement on the front surface 11 and the back surface 12 may be different.

[0046] When the anti-slip areas 30 are arranged on both the front surface 11 and the back surface 12 of the comforter bedding 10, particularly preferred combinations of arrangements are as follows. Combination 1: Front 11: Layout A1, Back 12: Layout A2 Combination 2: Front 11: Layout A1, Back 12: Layout B Combination 3: Front 11: Layout A1, Back 12: Layout F Combination 4: Front 11: Layout B, Back 12: Layout F

[0047] (30% of the non-slip area) When the non-slip area 30 is provided on either the front surface 11 or the back surface 12 of the comforter bedding 10, the ratio of the area of ​​the non-slip area 30 to the area of ​​the front surface 11 or the back surface 12 on which the non-slip area 30 is provided is set to 40% or more and 100% or less, and preferably 60% or more and 100% or less. The ratio of the area of ​​the non-slip area 30 to the total area of ​​the front surface 11 (surface area) and the back surface 12 (surface area) is set to 20% or more and 100% or less, and preferably 30% or more and 100% or less.

[0048] For example, if the anti-slip area 30 is provided only on the surface 11 of the duvet 10, the length L12 of the duvet 10 in the longitudinal direction is 210 cm, the arrangement of the anti-slip area 30 is arrangement A1 shown in Figure 2, and the width L2 of the anti-slip area 30 is 29 cm, the proportion of the area of ​​the anti-slip area 30 to the area of ​​the surface 11 of the duvet 10 is 41.4%, and the proportion of the area of ​​the anti-slip area 30 to the total area of ​​the area (surface area) of the surface 11 and the area (surface area) of the back surface 12 is 20.7%.

[0049] When the anti-slip area 30 is provided on both the front surface 11 and the back surface 12 of the comforter bedding 10, the ratio of the area of ​​the anti-slip area 30 to the area of ​​at least one of the front surface 11 or the back surface 12 is set to 40% or more and 100% or less, and preferably 40% or more and 100% or less. The ratio of the area of ​​the anti-slip area 30 to the area of ​​each of the front surface 11 and the back surface 12 may be set as described above. The ratio of the area of ​​the anti-slip area 30 to the total area of ​​the front surface 11 (surface area) and the back surface 12 (surface area) is set to 20% or more and 100% or less, and preferably 40% or more and 60% or less.

[0050] For example, if the anti-slip areas 30 are provided on both the front surface 11 and the back surface 12 of the duvet 10, the length L12 of the duvet 10 in the longitudinal direction is 210 cm, the arrangement of the anti-slip areas 30 is arrangement A1 shown in Figure 2 on both the front surface 11 and the back surface 12, and the width L2 of the anti-slip areas 30 is 29 cm, the proportion of the area of ​​the anti-slip areas 30 to the area of ​​the front surface 11 or the back surface 12 of the duvet 10 is 41.4%, and the proportion of the area of ​​the anti-slip areas 30 to the total area of ​​the area of ​​the front surface 11 (surface area) and the area of ​​the back surface 12 (surface area) is 41.4%.

[0051] (Use of duvet 10) The comforter bedding 10 is used while being housed within a bedding cover 100 (Fig. 3). In this embodiment, the comforter bedding 10 is a comforter, and the bedding cover 100 is a comforter cover. The bedding cover 100 is a well-known bag-shaped cover formed by sewing the peripheries of first and second fabrics 103 and 104. By housing the comforter bedding 10 of this embodiment within the bedding cover 100, the non-slip area 30 comes into contact with the inner surfaces 101 and 102 of the first and second fabrics 103 and 104 of the bedding cover 100, generating friction between the inner surfaces 101 and 102 of the bedding cover 100 and the non-slip area 30. This prevents the comforter bedding 10 from shifting position inside the bedding cover 100 when the comforter bedding 10 is used with the bedding cover 100 on.

[0052] When the comforter bedding 10 is housed in the bedding cover 100, any point on the front surface 11 or back surface 12 of the comforter bedding 10 on which the anti-slip area 30 is provided is designated as point a, any point on the surface of the bedding cover 100 opposite point a is designated as point b, and the distance between points a and b in a plan view is designated as distance L. The amount of misalignment of the comforter bedding 10 with respect to the bedding cover 100 is calculated as the difference between distance L on the comforter bedding 10 before use and distance L on the comforter bedding 10 after use. The amount of misalignment is preferably 2.0 cm or less, more preferably 1.6 cm or less, and even more preferably 0.8 cm or less. The amount of misalignment may be calculated as the average value when multiple points a and b are provided, or may be the average value calculated by performing multiple measurements.

[0053] (Second embodiment) 10 to 12 show a bedding cover 20 according to a second embodiment of the present invention. The bedding cover 20 accommodates bedding 110 therein. Fig. 10 is a perspective view of the bedding cover 20 according to one embodiment of the present invention, and Fig. 11 is a plan view of the bedding cover 20. Fig. 12 is a cross-sectional view of the bedding cover 20 accommodating the bedding 110.

[0054] The bedding 110 may be a comforter, mattress cover, pillow, blanket, etc., and the bedding cover 20 may be any of a comforter cover, mattress cover, pillow cover, blanket cover, etc. The bedding cover 20 is rectangular, and below, the bedding cover 20 will be described using as an example a comforter cover that accommodates the bedding 110, which is a single-size comforter. The bedding cover 20 is a single size, with a width L21 of 150 cm and a length L22 of 215 cm.

[0055] The bedding cover 20 of this embodiment is not limited to single size and may be any size, for example, a semi-double size with a width L21 of 170 cm, a double size of 190 cm, a queen size of 210 cm, or a king size of 230 cm. In most cases, the length L22 of any size is 210 cm. Note that Figures 10 to 12 do not represent the actual bedding cover 20, but are used for explanation purposes.

[0056] As shown in Fig. 10, the bedding cover 20 is formed into a bag shape by sewing the peripheral edges of a rectangular first fabric 23 and a rectangular second fabric 24 together, leaving an opening 25 for inserting and removing the bedding 110. The bedding 110 is stored inside.

[0057] The bedding cover 20 has a first inner surface 21 and a second inner surface 22 that face the front and back surfaces of the bedding 110. The first inner surface 21 and the second inner surface 22 are the surfaces that appear when the bedding cover 20 is turned inside out. At least one of the first inner surface 21 and the second inner surface 22 is provided with an anti-slip area 30. Details of the anti-slip area 30 will not be explained here, as it is the same as the anti-slip area 30 in the first embodiment.

[0058] The arrangement pattern of the anti-slip areas 30 on the first inner surface 21 and the second inner surface 22 is the same as arrangements A to F described in the first embodiment, and therefore the explanation of arrangements A to F will be omitted. That is, in arrangements A to F described in the first embodiment, the anti-slip areas 30 are arranged on the first inner surface 21 and the second inner surface 22 of the bedding cover 20 instead of on the surface 11 of the comforter 10.

[0059] In the examples of FIGS. 10 to 12, the anti-slip areas 30 are arranged on the first inner surface 21 in the pattern of arrangement A, but they may be arranged in any of the arrangement patterns of arrangements B to F.

[0060] The anti-slip areas 30 are arranged on at least one of the first inner surface 21 and the second inner surface 22 in any of arrangements A to F. That is, they may be arranged on either the first inner surface 21 or the second inner surface 22, or on both the first inner surface 21 and the second inner surface 22. When they are arranged on both surfaces, the arrangements on the first inner surface 21 and the second inner surface 22 may be different.

[0061] The arrangement combinations when the anti-slip area 30 is arranged on both the first inner surface 21 and the second inner surface 22 are the same as combinations 1 to 5 when the anti-slip area 30 of the first embodiment is arranged on both the front surface 11 and the back surface 12 of the duvet 10, so explanations will be omitted.

[0062] (30% of the non-slip area) When the non-slip area 30 is provided on either the first inner surface 21 or the second inner surface 22 of the bedding cover 20, the ratio of the area of ​​the non-slip area 30 to the area of ​​the first inner surface 21 or the area of ​​the second inner surface 22 on which the non-slip area 30 is provided is set to 40% or more and 100% or less, and preferably set to 60% or more and 100% or less. The ratio of the area of ​​the non-slip area 30 to the total area (surface area) of the first inner surface 21 and the area (surface area) of the second inner surface 22 is set to 20% or more and 100% or less, and preferably set to 40% or more and 100% or less.

[0063] When the non-slip area 30 is provided on both the first inner surface 21 and the second inner surface 22 of the bedding cover 20, the ratio of the area of ​​the non-slip area 30 to the area of ​​at least one of the first inner surface 21 or the second inner surface 22 is set to 40% or more and 100% or less, and preferably 40% or more and 100% or less. The ratio of the area of ​​the non-slip area 30 to the area of ​​each of the first inner surface 21 and the second inner surface 22 may be set as described above. The ratio of the area of ​​the non-slip area 30 to the total area (surface area) of the first inner surface 21 and the second inner surface 22 is set to 20% or more and 100% or less, and preferably 40% or more and 60% or less.

[0064] (Use of bedding cover 20) The bedding cover 20 of this embodiment is used with bedding housed inside. A quilt, which is one example of bedding 110, is a well-known item in which the peripheries of the outer and inner linings are sewn and a filler material is filled inside. By housing the bedding 110 in the bedding cover 20 of this embodiment, the non-slip area 30 comes into contact with the front surface 111 or back surface 112 of the bedding 110, and frictional force is generated between the front surface 111 or back surface 112 of the bedding 110 and the non-slip area 30. Therefore, when the bedding 110 covered with the bedding cover 20 is used, the bedding 110 can be prevented from shifting position inside the bedding cover 20.

[0065] When the bedding 110 is housed in the bedding cover 20, any point on the first inner surface 21 or second inner surface 22 of the bedding cover 20 on which the anti-slip area 30 is provided is designated as point a, any point on the surface of the bedding 110 opposite point a is designated as point b, and the distance between points a and b in a plan view is designated as distance L. In this case, the amount of misalignment of the bedding cover 20 with respect to the bedding 110 is calculated as the difference between distance L on the bedding cover 20 before use and distance L on the bedding cover 20 after use. The amount of misalignment is preferably 2.0 cm or less, more preferably 1 cm or less, and even more preferably 0.8 cm or less. The amount of misalignment may be calculated as the average value when multiple points a and b are provided, or may be the average value calculated by performing multiple measurements.

[0066] (Evaluation Test 1) The anti-slip fabrics of Examples 1, 2, and Comparative Example 1 were prepared as the anti-slip areas 30 used in the comforter bedding 10 and bedding cover 20 of the present invention, and the dynamic friction coefficient and static friction coefficient of the anti-slip fabrics were measured.

[0067] Example 1: Fabric: Tricot knit Weight: 79gsm Yarn composition: 61% polyester, 39% spandex (polyurethane elastic fiber)

[0068] Example 2: Fabric: Brushed suede Weight: 120gsm Yarn composition: 100% polyester

[0069] Comparative Example 1: Fabric: Cotton blend fabric Weight: 100gsm Yarn composition: 15% cotton, 85% polyester

[0070] The coefficients of friction of Examples 1 and 2 and Comparative Example 1 (hereinafter also referred to as "samples") were measured as follows. Measurements were made using a measurement system 200 shown in FIG. 13 in an environment of a temperature of 20°C and a humidity of 65% RH. A stainless steel plate 204 was placed on a support stand 205 with a horizontal surface, and the four corners were fixed with tape. Next, a 7 cm × 7 cm sample 201 was placed on the stainless steel plate 204, and a slider 202 weighing 200 g was placed on the sample 201. Furthermore, a load (weight) 203 weighing 500 g was placed on the slider 202. Next, the static and dynamic coefficients of friction were measured when the slider 202 was pulled at a speed of 100 mm / min using a tensile tester (not shown).

[0071] The results are shown in Table 1. As a result, it was revealed that in Examples 1 and 2, the static friction coefficient and dynamic friction coefficient were higher than those in Comparative Example 1, being 0.8 or higher.

[0072] [Table 1]

[0073] (Evaluation Test 2) The positional misalignment between the bedding cover 100 and the comforter 10 was evaluated. As the comforter 10 of the present invention, comforters of Examples 3 to 7 and Comparative Example 2 were produced. The comforters of Examples 3 to 7 and Comparative Example 2 are as follows.

[0074] Example 3: Location of anti-slip area 30: Surface 11 only Arrangement pattern of the non-slip area 30: Arrangement F shown in FIG. 9 (non-slip areas 30 arranged on the entire surface)

[0075] Example 4: Location of anti-slip area 30: Surface 11 only Arrangement pattern of the anti-slip areas 30: Arrangement A1 shown in FIG. 1 (three anti-slip areas 30 arranged) Width of anti-slip area 30 L2: 29cm

[0076] Example 5: Location of anti-slip area 30: Surface 11 only Arrangement pattern of the anti-slip areas 30: Arrangement A1 shown in FIG. 1 (three anti-slip areas 30 arranged) Width of anti-slip area 30 L2: 34cm

[0077] Example 6: Location of anti-slip area 30: Surface 11 only Arrangement pattern of the anti-slip areas 30: Arrangement A1 shown in FIG. 1 (three anti-slip areas 30 arranged) Width of anti-slip area 30 L2: 42cm

[0078] Example 7: Position of anti-slip area 30: both the front surface 11 and the back surface 12 Arrangement pattern of the anti-slip areas 30 on the surface 11: Arrangement F shown in FIG. 9 (anti-slip areas 30 arranged on the entire surface) Arrangement pattern of the anti-slip areas 30 on the back surface 12: Arrangement A1 shown in FIG. 1 (three anti-slip areas 30 arranged) Width L2 of backside 12 anti-slip area 30: 29cm

[0079] Matters common to Examples 3 to 7 and Comparative Example 2: Size of Comforter 10: Single size (150cm x 210cm) Bedding cover 100 (duvet cover): Single size (150cm x 210cm) (publicly known) First and second fabrics 103, 104 of the bedding cover 100 (quilt cover): 100% cotton Anti-slip area 30 (Examples 3 to 7 only): Anti-slip fabric similar to that of Example 1

[0080] (Method for measuring misalignment) The positional deviation between the bedding cover 100 and the comforter 10 was measured as follows: First, as shown in Figure 14(A), markers a1 to a4 were placed at the four corners of the surface 11 of the comforter 10. Furthermore, markers a5 and a6 were placed at the center positions in the width direction on both end edges in the length direction, and markers a7 and a8 were placed at the center positions in the length direction on both end edges in the width direction.

[0081] Also, Figure 14(B) shows the inner surface 101 of the bedding cover 100. The inner surface 101 faces the front surface 11 of the comforter 10 when the comforter 10 is placed inside the bedding cover 100. Figure 14(B) is a view of the inner surface 101 as seen from the comforter 10 side. Markers b1 to b4 are marked at four corners that roughly face the markers a1 to a4. Furthermore, markers b5 and b6 are marked at the widthwise center positions of both lengthwise end edges of the inner surface 101, respectively, and markers b7 and b8 are marked at the lengthwise center positions of both widthwise end edges, respectively.

[0082] The comforter bedding 10 of Examples 3 to 7 and Comparative Example 2 is housed in a bedding cover 100. In this state, the comforter bedding 10 housed in the bedding cover 100 is spread out and placed on a flat table, and the distances between markers a1 to a8 on the comforter bedding 10 and markers b1 to b8 on the bedding cover 100 at positions corresponding to markers a1 to a8 are measured in a plan view. That is, when the comforter bedding 10 is viewed from above, the distance between markers a1 and b1, the distance between markers a2 and b2, and ... are measured (pre-dumping measurement).

[0083] Next, the sample is folded in quarters and placed in a tumble dryer and run for three minutes (hereinafter also referred to as "tumble"). The tumble dryer is a dryer that dries the sample by rotating it while applying heat. After running, similar to the pre-tumble measurement, the distances between the markers a1 to a8 on the comforter bedding 10 and the markers b1 to b8 on the bedding cover 100 are measured (post-tumble measurement).

[0084] Next, the difference in distance between the markers a1 to a8 and the markers b1 to b8 before and after the dump is calculated, respectively. This difference is the amount of positional deviation (calculation of positional deviation).

[0085] The average value of the distances between markers a1 to a8 and markers b1 to b8 in the pre-dumping measurement was calculated. The average value of the distances between markers a1 to a8 and markers b1 to b8 in the post-dumping measurement was also calculated. Furthermore, the average value of the positional deviation amounts between markers a1 to a8 and markers b1 to b8 obtained in the positional deviation calculation was calculated.

[0086] The series of measurements before and after dipping, and calculation of positional deviation were performed three times. Each time, the average values ​​of the measurements before and after dipping and the average values ​​of the positional deviation calculation were calculated, and for each value, the average of the three measurements was calculated. The results are shown in Table 2.

[0087] In Comparative Example 2, the positional deviation was 9 cm or more in measurements before and after dumble. However, in Comparative Examples 3 to 7, even Example 3, which had the greatest positional deviation, had a positional deviation of 2 cm, which was smaller than that of Comparative Example 2.

[0088] [Table 2]

[0089] (Evaluation Test 3) Example 8 and Comparative Example 3 were produced as bedding 10 (duvet) using anti-slip fabrics with different coefficients of friction, and the amount of positional deviation was measured.

[0090] The anti-slip areas 30 are as follows: Example 8: Anti-slip fabric similar to Example 1 (static friction coefficient 0.91, dynamic friction coefficient 0.80) Comparative Example 3: A two-layer knit fabric composed of 46% modal, 9% polyurethane, and 45% polyester (static friction coefficient 0.61, dynamic friction coefficient 0.67)

[0091] Common points between Example 8 and Comparative Example 3: Size of Comforter 10: Single size (150cm x 210cm) Bedding cover 100 (duvet cover): Single size (150cm x 210cm) (publicly known) First and second fabrics 103, 104 of the bedding cover 100 (quilt cover): 100% cotton Location of anti-slip area 30: Surface 11 only Arrangement pattern of the anti-slip areas 30: Arrangement A1 shown in FIG. 1 (three anti-slip areas 30 arranged) Width of anti-slip area 30 L2: 42cm

[0092] In Example 8 and Comparative Example 3, the same procedure as the above-mentioned method for measuring misalignment was repeated three times: measurement before and after dipping, measurement after dipping, and calculation of misalignment. The average values ​​of the measurements before and after dipping and the average values ​​of the calculation of misalignment were calculated for each run, and the average of the three measurements was calculated for each value. The results are shown in Table 3.

[0093] [Table 3]

[0094] In Example 8, the positional deviation amount (average value) was 0.8 cm, but in Comparative Example 3, the positional deviation amount (average value) was 4.2 cm. It was confirmed that the positional deviation amount was small in Example 8, where the friction coefficient was 0.8 or more.
