Description

Technical Field

[0001] This invention relates to the field of bedding manufacturing technology, specifically to a multi-compartment, moderately pressed, anti-slip, washable bedding. Background Technology

[0002] As an essential household product, comfort and ease of cleaning are core performance indicators for bedding. Currently, bedding products filled with down, cotton, or silk floss have significant technical defects in their structural design: One type of product uses a high-density quilting design with a stitch spacing of less than 10cm. While this can limit the displacement of the filling to some extent, excessive restraint prevents the filling from naturally expanding, resulting in a stiff, hard feel and a significant reduction in warmth and loft. Furthermore, the multiple layers of quilted fabric make it difficult for water to evaporate after washing, leading to extremely low drying efficiency. Another type of product uses sparse quilting or a large-area compartment design, allowing too much space for the filling to move. During machine washing and spin drying, the filling is prone to piling up, shifting, and clumping, making it impossible to restore its flatness after use and severely impacting the user experience.

[0003] In addition, most existing bedding products are one-piece fixed structures, which cannot adjust the product thickness according to seasonal changes or usage scenarios, nor can they be modularly spliced, resulting in poor flexibility and difficulty in meeting the diverse and personalized needs of users. Currently, there is a lack of efficient solutions that address these common industry problems by simultaneously achieving anti-leaking, high loft, easy washing, and modular adjustment. Summary of the Invention

[0004] I. Purpose of the Invention

[0005] This invention addresses the technical pain points of existing filled bedding products, such as unreasonable stitch spacing, easy cotton leakage and clumping, stiff feel, and inability to be modularly adjusted. It provides a multi-grid, moderately stitched, washable bedding product that prevents cotton leakage. By optimizing the grid partitioning and stitching parameters, it achieves a balance between preventing filling displacement and product fluffiness, while improving the product's washability and flexibility, thus solving the inherent defects of traditional products.

[0006] II. Technical Solution

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] A multi-compartment anti-shifting washable bedding product comprises at least two independent filling compartments, separating seams, and an internal fixing structure. Each independent filling compartment is formed by sewing together an outer fabric and an inner fabric. The separating seams are sewn along the interface between the outer and inner fabrics, dividing them into multiple independent, non-interconnected filling cavities, structurally preventing the filling from shifting between different compartments.

[0009] Each individual filled cell contains an internal fixing structure, specifically quilting stitches. These quilting stitches simultaneously connect and fix the outer fabric, the inner fabric, and the internal filling, achieving localized constraint on the filling. The core technology of this invention is defined as follows: the spacing between adjacent quilting stitches within a single cell is controlled to be 15cm-25cm, or the quilting stitch density within a single cell is 3 stitches / m. 2 -5 items / m 2 This parameter range is the critical effective density threshold verified by experiments, and it is a key technical feature that balances the anti-runaway cotton effect with the product's fluffiness and softness.

[0010] Furthermore, the bedding features connecting and fixing structures at the edges and corners of the grid pattern. These structures utilize one or more combinations of zippers, Velcro, buttons, and snaps. This allows for the splicing, stacking, or disassembly of multiple bedding modules, adapting to different size usage scenarios and flexibly adjusting the product's thickness and warmth.

[0011] The technical principle of this invention is as follows: the first-level separation of the filling material is achieved through multi-grid partitioning, which prevents cross-grid movement; combined with the moderate density of quilting lines inside each grid, the second-level fixation of the filling material is achieved, which not only limits the displacement distance of the filling material within each grid to prevent clumping after washing, but also retains sufficient space to expand and ensure the fluffiness of the product; the quilting line spacing of 15cm-25cm avoids the dual drawbacks of conventional overly dense or sparse quilting lines, and has non-obvious technical advantages.

[0012] III. Beneficial Effects

[0013] 1. Balancing anti-loosening and high loft: The critical quilting spacing of 15cm-25cm avoids the product from becoming hard and clumping due to excessively dense quilting, and also solves the problem of filling displacement and clumping caused by excessively sparse quilting. After washing, the product retains more than 90% of its loft and feels soft and comfortable.

[0014] 2. Excellent washing performance: The product can be directly machine washed, washed, spun dry, and tumble dried. The multi-compartment design, combined with internal pressure lines for double fixation, ensures that the displacement rate of the filling is less than 5% after washing, making the product less prone to deformation and eliminating the need for manual secondary adjustment of fluffiness.

[0015] 3. Modular and flexible use: With the connecting and fixing structure, it can be freely spliced ​​to adapt to different bed sizes. The product thickness can also be adjusted by stacking and splitting, making it suitable for use in all seasons and truly realizing multiple uses for one quilt, thus improving the product's practicality.

[0016] 4. Wide range of applications: It is compatible with conventional bedding fillings such as cotton, down, silk floss, wool, and camel hair. It is suitable for all types of bedding, including quilts, comforters, mattresses, mattress pads, sleeping bags, and pillows. The production process is mature and easy to mass-produce and promote.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.

[0023] Example 1

[0024] This double-sized nine-compartment down comforter uses pure cotton fabric for both the top and bottom layers. The comforter is divided into nine evenly spaced square compartments by dividing seams. These compartments are fully sealed to prevent the filling from shifting. Each compartment has parallel quilted stitching, with a 20cm spacing between adjacent stitches and eight stitches per compartment. After filling the compartments with down, the openings are sealed. Invisible Velcro closures are sewn along the four sides and corners of the comforter for secure fastening.

[0025] Performance Comparison Test: The down comforter of this embodiment and a commercially available ordinary high-density quilted down comforter (quilting spacing 10cm) were washed and spun dry in a standard household washing machine at 800 rpm. Test Results: The product of this embodiment had a filling displacement rate of 3.2%, a loft retention rate of 94% after washing, and a soft and fluffy feel; the ordinary product had a filling displacement rate of 18.5%, a loft retention rate of only 62%, and a noticeably stiff and hard feel.

[0026] Example 2

[0027] The modular interlocking mattress is made of multiple 50cm×50cm square mattress modules. Each module is divided into an independent filling grid by dividing seams. The inside of the grid is quilted with cross stitches with a stitch spacing of 18cm. The inside is filled with high-elastic silk floss. The edges of the modules are sewn with invisible zippers as a connecting and fixing structure.

[0028] When in use, users can assemble multiple mattress modules into a complete mattress according to the size of the bed. They can also increase the thickness and softness of the mattress by stacking multiple layers. After disassembly, the mattress can be washed and stored separately, greatly improving the convenience of use and maintenance.

[0029] Experimental results show that when the quilting stitch spacing is less than 15cm, the fabric exerts excessive restraint on the filling, preventing the filling from expanding, resulting in a stiff feel and a sharp drop in comfort. When the stitch spacing is greater than 25cm, the restraint on the filling is insufficient, leading to significant displacement and clumping issues after washing. Only a stitch spacing of 15cm-25cm can achieve the optimal balance between preventing cotton leakage and high loft. This parameter selection is not a conventional technical approach in this field and possesses outstanding substantive characteristics and significant progress.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
