Description

Technical Field

[0001] This invention belongs to the field of home textile technology, and specifically relates to a bedding set and bedding products. Background Technology

[0002] In existing bedding sets, the comforter insert and duvet cover are prone to relative slippage during use, especially when the user turns over or moves. When the coefficient of friction at the contact interface between the comforter insert and duvet cover is insufficient, the shearing force generated by human movement can easily cause the comforter insert to shift inside the duvet cover, affecting comfort and the smoothness of the appearance.

[0003] To address these issues, common methods include adding ties at the four corners or edges of the duvet cover, or applying a non-slip coating to the entire or large area of ​​the fabric. However, ties are cumbersome to install and only work on localized areas, failing to effectively prevent slippage in the central region. Coatings, on the other hand, can affect the fabric's original softness, breathability, and comfort, potentially causing a foreign body sensation, especially on surfaces in contact with the skin, thus reducing the user experience.

[0004] Knitted fabrics, with their loop structure, possess good extensibility, conformability, and in-plane deformation capabilities, and have been increasingly used in bedding sets to reduce slippage to some extent. However, relying solely on the structural characteristics of knitted fabrics is still insufficient to effectively suppress relative slippage in localized areas, especially in areas of concentrated body pressure and frequent activity. Under continuous shear force, relative displacement between the comforter insert and cover can still easily occur. Summary of the Invention

[0005] The purpose of this invention is to provide a bedding set and bedding products that can effectively suppress the relative slippage of the inner core within the cover structure, keep the inner core in a relatively uniform distribution state, and avoid the feeling of foreign objects, thus achieving synergistic optimization of comfort and anti-slip properties.

[0006] To address the aforementioned technical problems, the present invention provides a bedding set, comprising, The number of the sheets is at least two, and they are arranged opposite to each other; The sheet includes a first surface and a second surface; The first surface is used to contact the human body; the second surface is used to contact the inner core. The second surfaces of each of the aforementioned layers are arranged opposite to each other and together enclose a sleeve space for accommodating the inner core; the sleeve space has multiple corners; At least one of the sheets has at least one anti-slip area on its second side, and the anti-slip area has a dotted adhesive structure. The anti-slip zone includes at least one of a waist anti-slip zone, a corner anti-slip zone, and / or a leg anti-slip zone, wherein the waist anti-slip zone corresponds to the waist area of ​​the human body, the leg anti-slip zone corresponds to the leg area of ​​the human body, and the corner anti-slip zone is located at the corner.

[0007] In one embodiment of the present invention, the edge of the corner anti-slip zone is provided with a plurality of adhesive dotting structures, which together form the tire tread corner anti-slip line.

[0008] In one embodiment of the present invention, a plurality of adhesive dispensing structures are further provided on the inner side of the anti-slip line at the corner of the tire tread, and the adhesive dispensing structures together form a wavy corner anti-slip line.

[0009] In one embodiment of the present invention, the first surface is not provided with the anti-slip area, or at least one corner of the first surface is provided with the anti-slip area.

[0010] In one embodiment of the present invention, the anti-slip area includes at least one of the following forms: dot array, strip, corrugated, or grid.

[0011] In one embodiment of the present invention, the area of ​​the adhesive dispensing structure on the waist anti-slip area accounts for 20% to 40% of the total area of ​​the anti-slip area; and the area of ​​the adhesive dispensing structure on the leg anti-slip area accounts for 15% to 35% of the total area of ​​the anti-slip area.

[0012] In one embodiment of the present invention, the second surface is provided with at least two anti-slip areas, and the distribution density of the dispensing structure in the different anti-slip areas is different.

[0013] In one embodiment of the present invention, the anti-slip area further includes a buttock anti-slip area and / or a shoulder anti-slip area, wherein the buttock anti-slip area corresponds to the position of the human buttock and the shoulder anti-slip area corresponds to the position of the human shoulder.

[0014] In one embodiment of the present invention, the shoulder anti-slip area is provided with a dotted adhesive structure, which forms two symmetrically distributed wavy shoulder anti-slip lines.

[0015] In one embodiment of the present invention, the distribution density of the adhesive structure in the waist anti-slip area is greater than the distribution density of the adhesive structure in the buttock anti-slip area. The distribution density of the adhesive dots on the anti-slip area of ​​the buttocks is greater than the distribution density of the adhesive dots on the anti-slip area of ​​the legs.

[0016] In one embodiment of the present invention, the dispensing material of the dispensing structure is selected from at least one of silicone, thermoplastic elastomer, thermoplastic polyurethane or rubber materials.

[0017] In one embodiment of the present invention, a head contact area is also included, corresponding to the position of the human head; The anti-slip area is not provided on the head contact area.

[0018] In one embodiment of the present invention, the sheet is made of a knitted fabric, which is selected from at least one of weft-knitted, warp-knitted, single-knitted, double-knitted, or rib-knitted fabrics. The fiber material of the knitted fabric is selected from at least one of cotton, lyocell, modal, or blends thereof.

[0019] The present invention also provides a bedding product, comprising: Inner core; A bedding set comprising any one of the above descriptions, wherein the bedding set includes at least two of the said sheets, the second surfaces of each sheet being disposed opposite to and in contact with the inner core to suppress slippage of the bedding set relative to the inner core.

[0020] In one embodiment of the present invention, the bedding is a duvet cover set or a mattress and bed sheet set.

[0021] By adopting the above technical solution, this invention, as an example, has the following advantages and positive effects: It effectively suppresses the relative slippage of the inner core within the sleeve structure, reducing the offset, accumulation, or curling of the inner core during use, ensuring a relatively uniform distribution of the inner core over a long period. While achieving reliable anti-slip, the side in contact with the human body maintains the original softness, skin-friendliness, and breathability of the knitted fabric, avoiding any foreign body sensation, thus achieving a synergistic optimization of comfort and anti-slip performance. A more three-dimensional and reliable anti-slip system is formed through the combination of basic corner restraints and targeted restraints in areas with high human activity. By differentiating the proportion or distribution density of the adhesive structure in different anti-slip zones, the anti-slip strength can be flexibly adjusted according to the pressure and frequency of activity of different parts of the body, achieving a better balance between anti-slip effect, material usage, and fabric feel. This invention utilizes the inherent loop structure characteristics of the knitted fabric to achieve natural coverage of the inner core, combined with adhesive structures in different locations, forming a synergistic mechanism of overall fit and localized anti-slip locking.

Detailed Implementation

[0036] The technical solutions disclosed in this invention will be described in detail below with reference to specific embodiments.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0039] In this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used only for descriptive and distinguishing purposes and should not be construed as indicating or implying relative importance.

[0040] like Figure 1 As shown, the present invention provides a bedding set 100, which includes at least two opposing layers 110. Each layer 110 has a first surface 101 and a second surface 102, wherein the first surface 101 is for contacting the human body. Specifically, the first surface of one layer is for contacting the human body, while the first surface of the other layer faces away from the human body and towards the external space, and can also be used for contacting the human body, such as the hand, arm, or shoulder. The second surface 102 is for facing the inner core 109 and contacting the outer surface of the inner core 109. The second surfaces 102 of each layer 110 are arranged opposite each other and together enclose a sleeve space for accommodating the inner core 109, which is thus enclosed within the sleeve space.

[0041] In a typical application, when the inner core 109 is a duvet insert, the bedding set constitutes a duvet cover. The two opposing layers 110 are the opposite fabric layers of the duvet cover, and the second surface 102 of each layer 110 contacts the two sides of the duvet insert, forming a complete duvet cover set together with the duvet insert. When the inner core 109 is a mattress, the bedding set constitutes a mattress protector or fitted sheet, used to cover and protect the mattress. The layers 110 can be connected in a manner conventional in the art, such as sewing their perimeters, or in some embodiments, by adhesive bonding, as long as a closed or semi-closed cover space that can accommodate the inner core 109 is formed between the layers 110. The present invention does not specifically limit the connection method.

[0042] The bedding set 100 provided by this invention, by setting an anti-slip structure on the second surface 102 of each layer 110, i.e., the side facing the inner core 109, specifically increases the local friction coefficient between the inner wall of the cover space and the inner core 109. This effectively suppresses the relative slippage between the inner core 109 and the cover structure caused by human movement, stably constraining the inner core 109 to a predetermined position within the cover space. During use, the inner core 109 maintains a relatively uniform distribution, avoiding problems such as uneven distribution of the comforter, local thinning, or voids, thereby improving warmth retention, comfort, and the overall smoothness of the bedding. When the set is used as a mattress protector, it can also suppress the sliding and wrinkling of the mattress protector or fitted sheet relative to the mattress inner core 109, maintaining the smoothness of the mattress surface and comfort.

[0043] The fabrics used for each layer can be the same or different. For example, in some embodiments, at least one layer is made of knitted fabric. In other embodiments, all layers are made of knitted fabric. Knitted fabric is composed of interlocking loops, and its unique loop structure endows the fabric with, but not limited to, good extensibility, elastic recovery rate, and in-plane deformation ability. When used for duvet covers, this characteristic allows it to fit snugly around the inner core, naturally conforming to the curves of the human body and the shape of the inner core, thus providing a certain degree of anti-slip foundation and supporting the anti-slip function of the subsequent anti-slip zones.

[0044] As an example, the knitted fabric can be selected from at least one of weft-knitted, warp-knitted, single-knitted, double-knitted, or rib-knitted fabrics. When using a double-knitted fabric, the first and second layers can be composed of different materials. For example, the first layer may use lyocell fiber to improve skin-friendliness and softness; the second layer may use cotton or blended fibers to improve structural stability or the adhesion of the adhesive structure. The choice of fabric structure can also be tailored to anti-slip requirements. For example, in areas where anti-slip zones are needed, a more elastic and denser structure, such as knitted jacquard, can be used locally to provide a better foundation for the adhesion of the adhesive structure.

[0045] In one embodiment, the fiber material of the knitted fabric can be selected from at least one of cotton, lyocell, modal, or blends thereof. Cotton fibers are skin-friendly, breathable, and have good moisture absorption; lyocell fibers are smooth to the touch and have good moisture absorption and breathability; modal fibers are soft and fluffy. By selecting different fiber materials, the skin-friendly comfort required for the first side and the anti-slip functionality required for the second side of each layer can be flexibly adjusted, thereby achieving synergistic optimization of comfort and anti-slip properties.

[0046] In one embodiment, to adapt to the force characteristics of the human body during use, the anti-slip areas 103 of the present invention are not uniformly distributed, but rather functionally zoned. Specifically, the anti-slip areas 103 provided on the second surface 102 include at least one of a waist anti-slip area 105, a corner anti-slip area 107, and a leg anti-slip area 106, that is, as... Figure 2 As shown, the second surface 102 is provided with a waist anti-slip area 105, or as... Figure 3 As shown, the second surface 102 is provided with a leg anti-slip area 106, or as... Figure 4 As shown, the second surface 102 is provided with a leg anti-slip area 106 and a waist anti-slip area 105, or as... Figure 5 As shown, a corner anti-slip area 107 is provided on the second surface 102.

[0047] The anti-slip zone 105 for the waist corresponds to the area where the waist is located when the person is lying supine or on their side. As an example and not a limitation, this area is roughly located in the upper middle part of the length of the bedding set 100. Since the waist of the human body generates a large normal pressure when lying flat, it is one of the core areas of pressure concentration and also a key location for shear force transmission during movements such as turning over. Therefore, setting the anti-slip zone 105 in this area can effectively increase the interfacial friction of this area, suppress the relative slippage tendency of the inner core 109 in the pressure concentration area, and limit the inner core 109 in the set structure to the predetermined position corresponding to the waist area of ​​the human body.

[0048] The anti-slip leg area 106 corresponds to the area where the human leg is located. By way of example and not limitation, this area is roughly located in the lower part of the bedding set 100 along its length. Because the human leg area is frequently active during use, such as turning over, bending the knees, or kicking, it generates periodic, variable-direction shear forces. Providing the anti-slip leg area 106 in the leg area can buffer and dampen these dynamic forces, suppressing the cumulative displacement of the inner core 109 within the bedding structure corresponding to the leg area, thereby effectively reducing the offset and accumulation of the inner core 109 within the bedding structure caused by human leg movements.

[0049] The corner anti-slip area 107 is provided at at least one corner. As an example, the corner anti-slip area 107 may be provided on any one, two, or three corners, or it may be provided on all corners. The main function of the corner anti-slip area 107 is to provide basic fixation for the edge position of the inner core 109, preventing the inner core 109 from undergoing large-scale overall movement or curling within the sleeve space.

[0050] like Figure 5 As shown, in this invention, taking a bedding set 100 composed of two layers 110 as an example, each layer 110 has four corners on its second surface 102, resulting in a total of eight corners on the second surfaces 102 of the two layers 110 for setting corner anti-slip areas 107. For example, corner anti-slip areas 107 can be set only at the four corners of the second surface 102 of one layer 110, or corner anti-slip areas 107 can be set at each corner of the second surfaces 102 of both layers 110, or corner anti-slip areas 107 can be set only at some corners according to actual anti-slip requirements. For example, in one embodiment, corner anti-slip areas 107 are respectively provided at the four corners of the second surface 102 of each layer 110. By fixing the four corner areas on both sides, the initial positioning stability between the comforter and the comforter cover is improved, effectively reducing overall slippage. The adhesive structure 104 of the corner anti-slip area 107 can be the same as or different from that of the waist anti-slip area 105 and the leg anti-slip area 106. For example, the corner anti-slip area 107 can use a dot array with a relatively small area and a relatively low distribution density, which is sufficient to provide basic positioning friction. By combining the corner anti-slip area 107 with the waist anti-slip area 105 and / or the leg anti-slip area 106, this combination of functional anti-slip areas 103 forms a synergistic anti-slip system that combines basic edge limiting of the inner core 109 with key limiting of areas with more human movement, making the overall anti-slip effect more reliable and three-dimensional.

[0051] By employing the aforementioned partitioning configuration, including at least one of the following: a waist anti-slip zone 105, a corner anti-slip zone 107, and / or a leg anti-slip zone 106, the present invention achieves targeted anti-slip enhancement for core stress and activity areas. It should be understood that those skilled in the art can, depending on actual needs, provide only the waist anti-slip zone 105, or only the leg anti-slip zone 106, or only the corner anti-slip zone 107, or both or all three simultaneously. Providing all three simultaneously typically achieves a more comprehensive anti-slip effect.

[0052] like Figure 1As shown, the anti-slip area 103 is provided with a dotted adhesive structure 104. Here, "dotted adhesive structure 104" refers to a local protrusion or attachment structure formed on the fabric surface by applying a material with a high coefficient of friction. Its function is to significantly increase the coefficient of friction between the local area and the contacting inner core 109, thereby forming a friction locking point and restricting the slippage of the inner core 109 relative to the sleeve during use.

[0053] It should be noted that the specific form of the adhesive structure 104 on each anti-slip area 103 of the present invention can be flexibly selected and combined according to anti-slip requirements, fabric characteristics, and aesthetic requirements. As an example and not a limitation, the anti-slip area 103 includes, but is not limited to, at least one of the following forms: dot array, strip, corrugated, or mesh. Furthermore, in the corner anti-slip area 107 or the shoulder anti-slip area 108, the adhesive structure 104 can also form more specific forms such as tire tread anti-slip lines or wavy anti-slip lines; their detailed arrangement will be described in conjunction with the accompanying drawings in later embodiments.

[0054] The dotted array refers to an array formed by multiple discrete adhesive dots arranged regularly or irregularly. This method provides multi-directional friction while having minimal impact on the fabric's feel and breathability, making it a well-balanced option. The adhesive dots can be circular, elliptical, rhomboid, or other polygonal shapes. The size and spacing of the adhesive dots can be adjusted according to the required anti-slip level and area. For example, in some embodiments, the diameter or maximum width of a single adhesive dot can be between 1.0 mm and 3 mm, and the center-to-center distance between adjacent adhesive dots can be between 2 mm and 8 mm. As an example, the protrusion height of the adhesive structure 104 can be selected between 0.05 mm and 0.5 mm. For example, for thinner knitted fabrics or those requiring a softer feel, the protrusion height of the adhesive structure 104 can be controlled between 0.05 mm and 0.3 mm to reduce the user's perception of the protrusion while providing friction; for thicker fabrics or applications requiring higher friction, the protrusion height of the adhesive structure 104 can be appropriately increased to 0.3 mm to 0.5 mm. The height of the protrusion of the dispensing structure 104 can be adjusted by controlling process parameters such as the amount of adhesive applied, the viscosity of the adhesive, or the dispensing pressure. This provides sufficient friction while reducing the feeling of foreign objects, thus ensuring comfort.

[0055] The strip-shaped form refers to a combination of multiple horizontal, vertical, or diagonal linear adhesive strips. The corrugated form refers to adhesive strips exhibiting periodic or non-periodic wavy curves. Both forms provide excellent shear resistance in the direction perpendicular to the extension direction of the adhesive strip. For example, a horizontally corrugated adhesive strip can improve the limiting effect in preventing the inner core 109 from slipping along the length of the sheath.

[0056] The mesh-like pattern refers to the intersecting adhesive lines forming a regular or irregular mesh structure. This pattern creates a continuous, multi-directional friction-enhancing surface, providing comprehensive and stable anti-slip performance.

[0057] Those skilled in the art can select the appropriate dispensing pattern based on the main direction of the shear force experienced by different anti-slip zones 103. For example, in the waist area, which mainly bears the shear force along the length of the duvet cover, a transverse corrugated or striped pattern can be used; in the leg area, where the direction of force is more variable, a dotted array or a grid pattern can be used, all of which are included within the scope of protection of this invention.

[0058] As an example, the dispensing material of the dispensing structure 104 can be selected from at least one of silicone, thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), or certain rubber materials. Silicone is a commonly used choice due to its excellent flexibility, weather resistance, and skin-friendly safety. Thermoplastic elastomers and thermoplastic polyurethanes are favored because of their adjustable hardness range, good processability, and strong adhesion to certain fabrics. Those skilled in the art can select a suitable dispensing material based on the fabric material, the required anti-slip level, cost budget, and production process. In one embodiment, liquid silicone requiring heat curing can be used, applied by a dispensing machine and then baked into shape; in another embodiment, hot-melt TPU adhesive can be used, processed by hot pressing or coating processes.

[0059] The materials constituting the dispensing structure 104 are not limited to the above embodiments. Those skilled in the art can select any material that can provide a sufficient coefficient of friction, adhere well to the fabric, and meet environmental protection and skin contact safety requirements, as needed. All such materials are included within the scope of protection of this invention.

[0060] In one embodiment, on the waist anti-slip area 105, the area of ​​the adhesive dot structure 104 accounts for 20% to 40% of the total area of ​​the anti-slip area 103. In other words, within the anti-slip area 103, 20% to 40% of the fabric surface is covered by adhesive material. Similarly, on the leg anti-slip area 106, the area of ​​the adhesive dot structure 104 accounts for 15% to 35%.

[0061] Depending on the actual usage scenario and the different needs for balancing comfort and slip resistance, the area ratio of the waist anti-slip zone 105 and the area ratio of the leg anti-slip zone 106 can present different relative relationships.

[0062] In some embodiments, the area percentage of the waist anti-slip zone 105 can be set to be greater than that of the leg anti-slip zone 106. The waist is the core area of ​​continuous pressure, requiring stronger friction and locking capabilities; therefore, increasing the area percentage of the adhesive structure 104 plays a major stabilizing role. Meanwhile, the leg area uses a relatively lower area percentage of the adhesive structure 104, sufficient to suppress slippage of the inner core 109 while maintaining freedom of movement in the leg area. For example, the area percentage of the waist anti-slip zone 105 can be set to 30% to 40%, while the area percentage of the leg anti-slip zone 106 can be set to 15% to 25%, creating a significant gradient difference between the two.

[0063] In other embodiments, the area ratio of the adhesive structure 104 in the waist anti-slip area 105 and the area ratio of the adhesive structure 104 in the leg anti-slip area 106 can also be set to be approximately equal, with both values ​​taking values ​​within the overlapping range, such as 25% or 30%. This setting can provide a more balanced anti-slip force for the waist and leg areas, and is suitable for usage scenarios where the anti-slip requirements for the waist and leg areas are not significantly different and overall consistency is desired.

[0064] In some other implementations, depending on the activity habits of specific users, such as people who move their legs abnormally frequently or kick the blanket forcefully, the area ratio of the leg anti-slip zone 106 can also be set to be greater than the area ratio of the waist anti-slip zone 105, in order to focus on addressing the dynamic slippage problem in the leg area.

[0065] The present invention achieves a flexible balance between comfort and anti-slip performance by flexibly adjusting the area ratio of the adhesive structure 104 in each anti-slip zone 103 according to the above-mentioned method.

[0066] Regarding the anti-slip structure of the first surface 101, in one embodiment, the first surface 101 does not have any adhesive dots 104. The advantage of this approach is that it preserves the original feel and characteristics of the first surface 101 as a human contact surface, such as softness, skin-friendliness, and breathability, reducing the foreign body sensation that might be introduced by the anti-slip design. With this arrangement, the anti-slip area 103 on the second surface 102 can also effectively restrain the comforter core, making this invention both comfortable and anti-slip.

[0067] In addition to the waist anti-slip zone 105 and leg anti-slip zone 106 described above, the anti-slip zone 103 can also be extended to other stress-bearing areas of the human body as needed.

[0068] In one embodiment, the anti-slip area 103 further includes a buttock anti-slip area and / or a shoulder anti-slip area 108. The buttock anti-slip area corresponds to the location of the human buttocks. The buttock area is one of the areas where pressure is mainly concentrated when the human body is in a sitting, reclining, or supine position, and body weight is transferred to the bed surface through the buttocks. Providing a buttock anti-slip area in this region helps to enhance the frictional engagement between the sleeve structure and the inner core 109 at the corresponding position on the buttocks. Figure 8 As shown, the anti-slip area 103 on the second surface 102 includes a corner anti-slip area 107, a waist anti-slip area 105, and a shoulder anti-slip area 108, wherein the shoulder anti-slip area 108 corresponds to the position of the human shoulder. The shoulder area bears greater concentrated pressure when the human body is lying on its side, and during the user's turning over, the shoulder will exert a relatively obvious pushing force on the duvet cover, which can easily cause the inner core 109 to slip. Providing a shoulder anti-slip area 108 at the corresponding position of the shoulder can improve the interface friction at that location to resist the shearing force brought about by the turning over action.

[0069] By providing anti-slip zones 103 on the second surface 102 corresponding to at least one of the human body's waist, hips, shoulders, and legs, and by flexibly configuring different forms, area proportions, or distribution densities of adhesive structures 104 for each anti-slip zone 103, a zoned anti-slip layout adapted to the force characteristics and activity patterns of different parts of the human body is formed. This zoned anti-slip layout can cover the main contact and force application areas between the human body and the bedding in various sleeping positions, improving the adaptability of the bedding set 100 to different usage states such as supine, side-lying, and turning over. For example, for users who are accustomed to sleeping on their side, the combination of anti-slip zones 103, including at least a shoulder anti-slip zone 108, can better adapt to the pressure characteristics of the shoulder when lying on their side and the pushing action when turning over.

[0070] In one embodiment, the second surface 102 is provided with at least two anti-slip areas 103, and the distribution density of the adhesive dispensing structures 104 in different anti-slip areas 103 is different. Specifically, when multiple anti-slip areas 103 including the aforementioned buttock anti-slip area 105, waist anti-slip area 105, and leg anti-slip area 106 are provided, the distribution density of the adhesive dispensing structures 104 in each anti-slip area 103 can be further differentiated to form a gradient anti-slip effect. Here, "distribution density" can be understood as the number of adhesive dots per unit area, or the percentage of the area covered by the adhesive dispensing structures 104. In one embodiment, the distribution density relationship of each anti-slip area 103 satisfies the following: the distribution density of the adhesive dispensing structures 104 in the waist anti-slip area 105 is greater than the distribution density of the adhesive dispensing structures 104 in the buttock anti-slip area; and the distribution density of the adhesive dispensing structures 104 in the buttock anti-slip area is greater than the distribution density of the adhesive dispensing structures 104 in the leg anti-slip area 106. This density-decreasing design from the waist and hips to the legs roughly corresponds to the pressure distribution and activity characteristics of the human body from the core to the extremities. Specifically, the waist, as the core pressure-bearing and force-transmitting area, receives strong friction; the hips, as the secondary pressure-bearing area, receive moderate friction; and the legs, as the frequently moving area, receive lower friction to maintain freedom of movement. This gradient configuration further improves the utilization efficiency of the anti-slip material, achieving effective anti-slip while minimizing the impact on overall flexibility and comfort.

[0071] It should be noted that the aforementioned anti-slip area 105 for the waist, anti-slip area 106 for the legs, anti-slip area for the buttocks (not shown in the figure), and anti-slip area 108 for the shoulders are exemplary anti-slip areas 103 designed for the main stress-bearing and frequently moving parts of the human body. This invention is not limited to providing anti-slip areas 103 only for the aforementioned body parts. Depending on individual user differences, specific usage scenarios, or further engineering optimization needs, anti-slip areas 103 can also be provided for other parts of the human body, such as providing anti-slip areas 103 for areas like the back, or further subdividing, merging, or reorganizing the aforementioned anti-slip areas 103. Any technical solution that functionally divides the second surface 102 according to body parts and configures differentiated anti-slip structures for different areas to achieve regional anti-slip effects should fall within the protection scope of this invention.

[0072] In one embodiment, the second surface 102 is provided with at least two anti-slip areas 103, and the distribution density of the dispensing structure 104 of these different anti-slip areas 103 is set to be different.

[0073] These anti-slip zones 103 can be any two or more combinations of the aforementioned waist anti-slip zone 105, leg anti-slip zone 106, hip anti-slip zone, shoulder anti-slip zone 108, and corner anti-slip zone 107. Different anti-slip zones 103 are assigned different distribution densities. For example, in a kit designed for individuals who frequently toss and turn over, the distribution density of the adhesive structure 104 in the leg anti-slip zone 106 can be set higher than that in the waist anti-slip zone 105 to accommodate their unique dynamic anti-slip needs. Similarly, considering the characteristics of children who are active and kick off their blankets, anti-slip zones 103 with a relatively higher distribution density of adhesive structure 104 can be set in the lower part of the duvet cover, such as the leg area, while anti-slip zones 103 with a relatively lower distribution density of adhesive structure 104 can be set in the upper part of the duvet cover, such as the shoulder area, or no anti-slip zones 103 may be provided. This invention flexibly implements differentiated anti-slip designs for different parts of the human body to achieve a balance between comfort and anti-slip properties in specific scenarios.

[0074] In one embodiment, the bedding set 100 further includes a head contact area corresponding to the position of the human head. The head contact area does not have the anti-slip area 103; that is, no adhesive dots 104 are applied to the first surface 101 and / or the second surface 102 within this area. This design takes into account the stress characteristics and comfort requirements of the human head area during use. Compared to areas with concentrated pressure such as the waist and hips, and areas with frequent movement such as the legs, the head area has a relatively lower need for anti-slip properties, but a more prominent requirement for softness and skin-friendliness. Preserving the original surface characteristics of the fabric in the head contact area avoids the localized stiffness or foreign body sensation that the adhesive dots 104 may cause, ensuring that the contact area between the user's head and face maintains a soft, breathable, and natural feel, achieving a synergistic optimization of the overall comfort and anti-slip properties of the bedding set 100.

[0075] In one embodiment, the present invention also provides a bedding product comprising an inner core and a bedding set as described in any of the above embodiments. The bedding set comprises at least two opposing layers, each layer having its second surface facing the inner core and respectively attached to both sides of the inner core, contacting the outer surface of the inner core. As previously described, since at least one layer has one or more anti-slip areas on its second surface, and the adhesive structure on the anti-slip areas has a high coefficient of friction, it can form a locally high-friction area at the contact interface between the layer and the inner core, thereby suppressing the slippage of the bedding set relative to the inner core during use, limiting the position of the inner core, and keeping the inner core stable within the bedding set space.

[0076] By way of example and not limitation, the bedding can be a duvet cover set. When the bedding is a duvet cover set, the inner core is the duvet core, and the bedding set is the duvet cover. The duvet cover includes two opposing layers, the first side of each layer is for contact with the human body, and the second side of each layer is for contact with the duvet core. By providing the aforementioned anti-slip structure on the second side of each layer, such as waist anti-slip zones and / or leg anti-slip zones corresponding to the waist and / or legs, and optionally corner anti-slip zones, the slippage, accumulation, or curling of the duvet core inside the duvet cover can be effectively inhibited, allowing the duvet core to remain evenly distributed for a long time, thereby continuously providing good warmth and comfort. The bedding set of the present invention is applicable to duvet cores of different sizes and filling types, such as down duvet cores, silk duvet cores, synthetic fiber duvet cores, or blended duvet cores.

[0077] In other embodiments, the bedding can be a mattress. When the bedding is a mattress, the inner core is the mattress core, and the bedding set is a cover structure used to cover the mattress core, such as a mattress protector or fitted sheet. The bedding set includes at least two opposing layers, the second side of each layer contacting the outer surface of the mattress core. The anti-slip structure on the second side of each layer inhibits slippage and wrinkling of the bedding set relative to the mattress core, maintaining a flat and conforming appearance on the mattress. This reduces shifting and curling caused by sitting, lying down, or moving, thus continuously providing protection and hygienic isolation for the mattress core.

[0078] It should be noted that the above-described duvet cover combination and mattress are merely two exemplary applications of the bedding products of this invention. The bedding products of this invention can also be other textile products comprising an inner core and an outer cover, and which experience relative slippage between the cover and the inner core during use. Any technical solution that applies the partitioned anti-slip structure described in this invention to the second surface of each layer of the cover in such products should fall within the protection scope of this invention.

[0079] In some other embodiments, the technical solution provided by this invention can also be extended to bed sheet products. Specifically, in this application, the bed sheet includes at least two partially opposing layers, each layer having a first surface for contacting the human body and a second surface for contacting a mattress or opposing layers. By arranging the second surfaces of at least two layers opposite each other in a local area, and providing an anti-slip area as described above on at least one second surface, the second surface provided on the adhesive structure is frictionally bonded to the opposing layer structure. For example, anti-slip areas can be provided at the edges or easily slippery parts of the bed sheet, or the corners of the bed sheet can be folded over to form opposing second surfaces, so that the anti-slip area is located between the two opposing second surfaces. By providing this local anti-slip structure at specific locations on the bed sheet, such as anti-slip areas corresponding to areas of concentrated pressure like the waist and buttocks, the interlayer friction coefficient of the bed sheet itself can be increased, suppressing slippage and wrinkles during use, reducing bed sheet shifting, curling, or wrinkling caused by human sitting, lying down, turning over, etc., thereby maintaining the flatness and aesthetics of the bed surface.

[0080] It should be noted that when the technical solution of the present invention is applied to bed sheets, those skilled in the art can make adaptive adjustments to the specific location, quantity, and configuration of the anti-slip area 103 according to the actual use and stress characteristics of the bed sheet. For example, since bed sheets usually do not need to consider the overall wrapping of the inner core 109 and the problem of corner movement as in duvet covers, the corner anti-slip area 107 can be omitted or simplified as appropriate; while the anti-slip areas 103 corresponding to the main pressure-bearing areas of the human torso, such as the waist and buttocks, can be correspondingly strengthened.

[0081] Example 1 like Figure 1 As shown, this embodiment provides a bedding set 100, which includes at least two opposing sheets 110. Each sheet 110 has a first surface 101 and a second surface 102. The first surface 101 is for contacting the human body, and the second surface 102 is for contacting the inner core 109. The second surfaces 102 of each sheet 110 are opposite to each other and are sewn together along their periphery to form a sleeve space for accommodating the inner core 109. Within this sleeve space, each of the two opposing sheets 110 has four corners on its second surface 102, for a total of eight corners.

[0082] In this embodiment, each layer 110 is made of 60S cotton modal blended knitted fabric, which is a weft-knitted double-sided knitted fabric.

[0083] In this embodiment, anti-slip areas 103 are provided on the second surface 102 of each layer 110. Specifically, a corner anti-slip area 107 is provided at each of the four corners of the second surface 102 of each layer 110. Each corner anti-slip area 107 has a dotted adhesive structure 104, which is a dotted array, formed by multiple discrete circular adhesive dots arranged in a regular pattern. The diameter of a single adhesive dot is approximately 1.0 mm to 3 mm, the center-to-center distance between adjacent adhesive dots is approximately 2 mm to 8 mm, and the area of ​​the adhesive dots within the anti-slip area 103 accounts for approximately 10% to 20%. Liquid silicone is used as the adhesive material, which is applied by a dispensing machine and then cured by baking.

[0084] This embodiment simultaneously sets anti-slip zones 103 at the four corners of the second surface 102 of each layer 110, forming multi-point friction locking in the diagonal areas within the cover space. This effectively increases the interfacial friction between the inner core 109 and the cover space, providing basic positional constraints for the inner core 109 and reducing the tendency for the inner core 109 to shift as a whole within the cover space. Taking a product where the inner core 109 is the comforter core and the cover structure is the comforter cover as an example, actual comparative testing shows that compared to ordinary comforters without any anti-slip structures, the bedding set 100 of this embodiment significantly improves the corner retraction problem of the comforter core, and the overall position of the comforter core within the comforter cover is more stable during use.

[0085] Example 2 The difference between this embodiment and Embodiment 1 is that: an anti-slip area 103 is provided only on the second surface 102 of one of the sheets 110, while the second surface 102 of the other sheet 110 does not have an anti-slip area 103. Specifically, as shown... Figure 5 As shown, corner anti-slip areas 107 are provided only at the four corners of the second surface 102 of one sheet 110 constituting the sleeve structure, while no adhesive dispensing structure 104 is provided at the four corners of the second surface 102 of the other sheet 110.

[0086] In this embodiment, the first surface 101 of each layer 110 is not provided with any adhesive structure 104, maintaining a soft and skin-friendly surface characteristic. The layer 110 with the anti-slip area 103 is made of 60S cotton knitted double-sided fabric, and its second surface 102 has an adhesive structure 104 in the same dot array as in Embodiment 1 at its four corners; the other layer 110 is made of 60S Lyocell double-sided knitted fabric, and neither its first surface 101 nor its second surface 102 is provided with an adhesive structure 104.

[0087] This embodiment maintains the original softness and breathability of the fabric by omitting the anti-slip structure on the first surface 101 of each layer 110, thus avoiding the foreign body sensation that may be caused by the presence of the adhesive structure 104. Simultaneously, the anti-slip area 103 at the corner of the second surface 102 of one of the layers 110 provides basic anti-slip positioning. Compared to Embodiment 1, this embodiment further improves the comfort of the human body contact side while ensuring a certain level of anti-slip performance.

[0088] Example 3 The difference between this embodiment and Embodiment 1 is that: Figure 7 As shown, on the second surface 102 of the sheet 110 where the anti-slip area 103 is provided, in addition to the corner anti-slip areas 107 at the four corners, a waist anti-slip area 105 is also provided at the position corresponding to the waist of the human body.

[0089] Specifically, the waist anti-slip zone 105 is located in the upper middle section of the sheet 110 along its length, with a width of approximately 8cm to 15cm. The adhesive structure 104 on the waist anti-slip zone 105 is in the form of a transverse corrugation or strip, extending along the width of the sheet 110. Compared to the corner anti-slip zone 107, the adhesive structure 104 of the waist anti-slip zone 105 has a higher area ratio, approximately 20% to 40%.

[0090] This embodiment enhances slip resistance by adding a waist anti-slip zone 105, specifically targeting the waist area where pressure is concentrated. During use, the waist anti-slip zone 105 provides significant local friction, effectively inhibiting the slippage of the inner core 109 within the sleeve space corresponding to the waist area, thus playing a primary limiting role. Compared to Embodiment 2, this embodiment improves the displacement inhibition effect of the inner core 109 in the central region by approximately 30% to 60%, resulting in more comprehensive overall anti-slip performance.

[0091] Example 4 The difference between this embodiment and embodiment 2 is that: Figure 6 As shown, on the second surface 102 of the sheet 110 where the anti-slip area 103 is provided, in addition to the corner anti-slip areas 107 at the four corners, a leg anti-slip area 106 is also provided at the position corresponding to the human leg.

[0092] Specifically, the anti-slip area 106 for the leg is located in the lower section of the sheet 110 along its length. The adhesive structure 104 on the anti-slip area 106 is in the form of a corrugated or intermittent strip, and the area of ​​the adhesive structure 104 accounts for approximately 15% to 35%.

[0093] This embodiment is suitable for use in scenarios where people frequently turn over or children have a lot of leg movements. The anti-slip zone 106 on the legs can buffer and dampen the periodic shear force generated in areas of frequent human movement, reduce the dynamic displacement of the inner core 109 in this area, suppress the displacement of the inner core 109 caused by actions such as turning over, bending the knee, or kicking, and improve the overall stability of the bedding set 100.

[0094] Example 5 The difference between this embodiment and embodiment 3 is that the anti-slip area 103 on the second surface 102 of the sheet 110 with the anti-slip area 103 adopts a gradient configuration based on the human body pressure distribution.

[0095] Specifically, in this embodiment, in addition to the corner anti-slip area 107, the second surface 102 of the sheet 110 is provided with multiple functional anti-slip areas 103 according to the pressure distribution characteristics of different parts of the human body, and the distribution density of the adhesive structure 104 in each anti-slip area 103 varies in a gradient. Specifically, the waist anti-slip area 105, corresponding to the waist position, has a higher distribution density, with the area of ​​the adhesive structure 104 accounting for approximately 30% to 50%; the buttock anti-slip area, corresponding to the buttock position, has a medium distribution density, with the area of ​​the adhesive structure 104 accounting for approximately 20% to 30%; and the leg anti-slip area 106, corresponding to the leg position, has a relatively low distribution density, with the area of ​​the adhesive structure 104 accounting for approximately 10% to 20%. Furthermore, no anti-slip area 103 is provided at the head position to retain the original soft touch of the fabric. The first surface 101 of the sheet 110 and the first surface 101 and second surface 102 of the other sheet 110 do not have adhesive structures 104.

[0096] This embodiment, through the aforementioned gradient configuration, ensures that the distribution density of the adhesive structure 104 is positively correlated with the pressure and activity frequency of different parts of the human body, thereby achieving a more reasonable balance between the amount of anti-slip material used, comfort, and anti-slip effect. This arrangement provides sufficient friction in the areas most requiring anti-slip properties while reducing the use of adhesive material in unnecessary areas, thus improving the overall balance between comfort and functionality.

[0097] Example 6 like Figure 9 and Figure 10 As shown, in response to the complex shear forces in multiple directions that the corners are subjected to during use, such as those originating from the curling and pulling of the comforter's edge and the torque when the body turns over, this embodiment further optimizes the structure of the anti-slip area 107 at the corners.

[0098] Specifically, a corner anti-slip area 107 is provided at at least one corner of the second surface 102, and the adhesive dispensing structure 104 within the corner anti-slip area 107 is arranged to form a continuous corner anti-slip line. The corner anti-slip line comprises two parts: Tire tread corner anti-slip line 107-1, such as Figure 10 As shown in the blue area: the outer edge of the corner is composed of densely arranged and interwoven adhesive structures 104, whose shape mimics the tread pattern of a tire, forming small grooves and protrusions in multiple directions. This structure has extremely strong anisotropic friction, which can effectively prevent the core 109 from slipping in any direction at the corner, especially having a good suppressive effect on torsional force.

[0099] Wavy corner anti-slip line 107-2, such as Figure 10 As shown by the pink and yellow lines: located on the inner side of the edge tire tread, it is formed by dotted or micro-strip adhesive structures 104 arranged along a wavy trajectory. The wavy corner anti-slip lines 107-2 are distributed in parallel or intersecting directions, forming a flexible anti-slip barrier with a wavy shape. This wavy design allows it to adapt to the stretching and elongation of the knitted fabric itself without adding too much hard adhesive, while providing effective local shear resistance. When the duvet insert 109 experiences relative displacement within the duvet cover at the corners, the wavy corner anti-slip lines 107-2 can increase the interlocking of the contact interface, thereby forming a firm local locking point.

[0100] By combining the outer tire tread corner anti-slip line 107-1 with the inner wavy corner anti-slip line 107-2, this embodiment significantly improves the anti-slip stability of the corners. This design, while maintaining the soft feel of the knitted fabric, effectively avoids reduced breathability and a foreign body sensation caused by large-area adhesive application, making it particularly suitable for heavy comforters or scenarios where the user frequently tosses and turns.

[0101] Example 7 like Figure 9 As shown, based on Embodiment 1, this embodiment, taking into account the characteristics of the human shoulder area, provides a shoulder anti-slip area 108 in the shoulder area of ​​the second surface 102. Specifically, the shoulder anti-slip area 108 is located along the length of the sleeve structure, or the Y-axis direction, at a distance of 20cm-30cm, preferably 25cm, from the upper edge near the head, to perfectly match the natural position of the shoulder when the human body is lying supine.

[0102] The adhesive structure 104 within the shoulder anti-slip zone 108 is arranged to form two symmetrically distributed wave-shaped shoulder anti-slip lines 108-1, corresponding to the pressure concentration areas of the left and right shoulders, respectively. Through the alternating wave crests and troughs, this structure can provide longitudinal shear resistance while enhancing the locking effect against lateral shoulder thrust, effectively suppressing local shifting of the comforter core caused by turning over or shoulder movement.

[0103] The wavy shoulder anti-slip line 108-1 extends along the width direction of the sleeve structure in the X-axis direction, with a total span of 30cm-60cm in the width direction. This width range is set based on human shoulder width data and can adapt to the shoulder pressure areas of users of different genders.

[0104] Example 8 To further verify the anti-slip stability of the technical solution of the present invention compared with the tie structure or pure knitted fabric in long-term use scenarios, the inventors referred to the QB / T 1952.2-2023 standard "Durability Test of the Central Area of ​​Mattress Surface" and conducted simulated use tests on bedding sets 100 with various structures.

[0105] Each test sample was laid flat on a mattress measuring 1.8m x 2.0m, using the edge of the mattress as a reference. Marking points were placed on the four sides of the sample, such as... Figure 11 As shown. The rolling test is performed according to the standard. First, the center area of ​​the pavement is rolled 100 times, and the spatial displacement of each marked point is recorded. Keeping the sample position unchanged, the center area of ​​the pavement is rolled another 100 times, for a total of 200 rolls, and the displacement of each marked point is recorded again. The main statistical indicators include the maximum offset in the left-right direction (X direction) and the maximum offset in the front-back direction (Y direction), and the offset radius R after 100 and 200 rolls is calculated using the following formula: .

[0106] As shown in Table 1, this test was divided into two groups. For ease of description, the two layers of the quilt cover are referred to as layer A and layer B, respectively. Layer A is the layer closer to the body, and layer B is the layer further away from the body. Each layer has a first side (facing the body or external space) and a second side (facing the quilt insert), and the anti-slip zone is located on the second side of each layer.

[0107]

[0108] Table 1 Test results are as follows Figure 12 As shown, the horizontal axis represents the maximum offset in the left-right direction (X), and the vertical axis represents the maximum offset in the front-back direction (Y). The scattered points in the figure represent the final positional offset of different samples in the rolling simulation test.

[0109] The data points for samples 1, 2, 3, 4, 6, and 7 are all concentrated in the lower left corner of the coordinate system, with X-direction offset values ​​<20mm and Y-direction offset values ​​<25mm. This indicates that regardless of whether adhesive is applied to both layers A and B, or only to layer B, as long as the corner area is covered and combined with anti-slip zones at the waist and / or legs, it can effectively suppress the cumulative displacement of the comforter core in the left-right and front-back directions during simulated long-term use, demonstrating excellent anti-slip stability. Among them, samples 6 and 3 have even lower Y-direction offsets, close to the origin of the coordinate system, further verifying the effectiveness of anti-slip design targeting areas of frequent human activity.

[0110] The data point for sample 5 is located at X≈43mm and Y≈24mm. Compared with samples 1-4 and 6-7, its left-right (X-axis) offset is significantly increased. This indicates that without the assistance of the adhesive structure 104, even if the knitted fabric itself has a certain degree of conformity, it is difficult to effectively resist the slippage of the quilt core along the lateral direction. The displacement mainly occurs in areas where the left-right offset dynamics are more intense.

[0111] Comparative Examples 1 (DY straps), 2 (TS straps), and 3 (Tencel-covered polyester knitted straps) – these three comparative samples, employing traditional strap structures or pure woven fabrics, all have data points scattered in the upper right region of the coordinate system, with significantly higher offsets than the samples in this invention. In particular, Comparative Example 3 (Tencel-covered polyester knitted straps) exhibits the largest Y-direction offset (Y≈89mm) among all tested samples; Comparative Example 2 (TS straps) also shows high offsets in both the X and Y directions (X≈38mm, Y≈38mm). This indicates that while traditional corner strap structures can provide some tensile fixation in specific directions, their constraint on the comforter core is significantly limited in multi-dimensional real-world sleeping and rolling simulation tests, easily leading to large-scale movement of the comforter core within the cover.

[0112] This embodiment illustrates that by providing at least corner anti-slip areas 107 on the second surface 102, and further combining them with waist anti-slip areas 105 and / or leg anti-slip areas 106, the present invention can form a multi-directional, multi-layered three-dimensional locking system. Experimental data shows that, compared with existing strap technologies, the present invention can significantly reduce the front-to-back and left-to-right offset of the inner core 109 during long-term use (especially after 200 high-frequency rolling cycles), effectively maintaining the uniformity of the inner core 109 distribution, while maintaining a good tactile feel of the A-layer against the skin, achieving a synergistic improvement in anti-slip performance and comfort.

[0113] In summary, this invention, by providing an anti-slip structure on the second surface 102 near the inner core 109 and configuring anti-slip zones 103 at least for the waist and / or leg areas, achieves targeted anti-slip enhancement for key stress-bearing and frequently moving areas. This effectively suppresses the relative slippage of the inner core 109 within the sleeve structure, reduces the offset, accumulation, or curling of the inner core 109 during use, and ensures that the inner core 109 maintains a relatively uniform distribution over a long period. Simultaneously, by omitting the anti-slip zone 103 on the first surface 101 in contact with the human body, a synergistic optimization of comfort and anti-slip performance is achieved. The first surface 101 maintains the original softness, skin-friendliness, and breathability of the knitted fabric, avoiding any foreign body sensation caused by the anti-slip structure. The second surface 102 provides the necessary interfacial friction through the adhesive structure 104, and the two do not interfere with each other. In addition, by combining the corner anti-slip zone 107 with the anti-slip zone 103 targeting different parts of the human body, an anti-slip system is formed that combines the basic edge limiting of the inner core 109 with the key limiting of parts of the human body that move frequently, making the overall anti-slip effect more reliable and three-dimensional.

[0114] In addition, in a further embodiment, by differentiating the area ratio or distribution density of the adhesive structure 104 of different anti-slip zones 103, the anti-slip force can be flexibly adjusted according to the pressure and frequency of activity of different parts of the human body, achieving a better balance between anti-slip effect and material usage and fabric feel.

[0115] This invention also selects a knitted fabric with good extensibility and conformability as the base material for the bedding set. Utilizing the inherent loop structure of the knitted fabric, it naturally covers the inner core 109, combining with the anti-slip area 103 to form a synergistic mechanism of overall conformability and localized anti-slip locking. Furthermore, the technical solution of this invention can be flexibly applied to various bedding products such as duvet covers, mattress protectors, fitted sheets, or sheets, exhibiting good adaptability and scalability.
