Description

Technical Field

[0001] The utility model belongs to the technical field of bedding products, and in particular relates to a feather-shaped cotton quilt. Background Art

[0002] Down quilts are the most commonly used filling material for quilt cores. The raw materials are down cores and feather pieces. Compared with plant cellulose such as cotton, they have the advantages of being gentle, warm, and breathable. However, down materials are expensive, and washing will have a certain impact on the fluffiness of the down. Some people are sensitive to the smell of down, and the shell fabric of the down quilt needs to be treated with anti-down, so there are many restrictions on the fabric. In order to combine the fluffy, warm, soft and silky properties of down, and overcome the defects of down being easy to drill, easy to accumulate, easy to be allergic, and having odor, bionic down such as EiderWarmth down (abbreviated as EW down) has been developed in the prior art. For example, Patent No. CN106460255B discloses a feather-like cotton raw material and a method for manufacturing the same. The feather-like cotton raw material is in the shape of a long line and has long cotton-like fibers around the edge, which is used to replace traditional cotton as the inner core. When feather-like cotton raw materials are used as the inner core of the quilt, since such feather-like cotton raw materials are in the form of long lines, they are easy to spread out, and are difficult to fix during the sewing process of the finished product. Moreover, they are easy to deviate or spread out after washing, and the washing retention is poor. Although, for example, the quilt formed by storing the core material in the three-dimensional structure area disclosed in Patent No. CN109906045B and its manufacturing method, firstly, a plurality of storage areas are formed by dividing the inner surface of the connecting edge and the front fabric or the inner surface of the back fabric, and the feather-like cotton raw materials are bundled and filled in each storage area, and then sewn and sealed, so that the quilt does not need quilting processing, and has good recovery and heat preservation after washing; for example, the feather-like cotton inner core fabric with W-shaped sewing disclosed in Patent No. CN212560666U, the yarn is sewn in a W-shape to a plurality of feather-like cotton raw materials arranged flat, which can achieve the effect of effectively fixing the feather-like cotton raw materials; however, the above method still has the following problems:

[0003] (1) The quilt shell needs to be sewn first, and then the feather-like cotton is inserted into the quilt shell in sequence. Therefore, the quilt shell fabric is required to have a certain degree of stiffness and width, which is limited to woven fabrics. Softer fabrics such as knitted fabrics are not suitable, which will inhibit the softness of the feather-like cotton itself. At the same time, after the feather-like cotton is inserted into the storage area with a three-dimensional structure in the shape of a triangular tube, the fluffiness will be limited, which affects the softness and comfort of the finished quilt.

[0004] (2) Although the quilt does not require quilting, the quilt shell is complicated to sew. It needs to be ironed and shaped before sewing, which increases the number of sewing steps and is inefficient. It is also necessary to insert the feather-like cotton into the quilt shell channel one by one, which is time-consuming, resulting in low production efficiency and high finished product cost. Although the feather-like cotton inner core fabric is fixed by special stitching, it limits the fluffiness of the feather-like cotton to a certain extent and reduces the sewing efficiency during the production of the quilt.

[0005] (3) The functionality of a quilt made with a single feather-like cotton filling is single. If other functional antibacterial and anti-mite functions or fibers are needed, they can only be added during the silk imitation process or through post-processing. The minimum order quantity is high, resulting in high processing and finished product costs. Utility Model Content

DETAILED DESCRIPTION

[0050] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0051] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "length", "width", "upper", "lower", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0052] Aiming at the technical problems in the prior art that feather-like cotton quilts are difficult to fix during sewing, have poor washability and recovery after washing, have many sewing steps, and have limited softness and comfort of the quilt, the goal is to fix the feather-like cotton without destroying its fluffiness, such as Figure 1 As shown in FIG. 1 , a preferred embodiment of the feather-like cotton quilt of the utility model is shown. The feather-like cotton quilt comprises an upper layer of wadding 11, a down cotton layer 12 and a lower layer of wadding 13 which are quilted as one and sequentially arranged from top to bottom. Figure 2 As shown, the down cotton layer 12 includes at least two layers of alternately stacked transverse cotton layers 121 and longitudinal cotton layers 122, the transverse cotton layer 121 includes a plurality of feather-like cotton bundles 123 arranged at intervals along the transverse direction, and the longitudinal cotton layer 122 includes a plurality of feather-like cotton bundles 123 arranged at intervals along the longitudinal direction, so that the feather-like cotton quilt forms a sandwich-like structure of upper, middle and lower parts.

[0053] The down cotton layer 12 serving as the core of the sandwich adopts a horizontal and vertical cotton structure, so that the feather-like cotton bundles 123 of the adjacent horizontal cotton layers 121 and the vertical cotton layers 122 can prevent the feather-like cotton from shifting relative to each other through mutual friction force, and then the upper and lower layers of the down cotton layer 12 are respectively covered with the upper flakes 11 and the lower flakes 13, and the feather-like cotton bundles 123 can be further fixed after being quilted as a whole, so that it is not easy to shift during use or washing. There is no need to sew the quilt shell 2 with a wide fabric and a storage area in advance, which also reduces the fabric demand of the quilt shell 2, the restrictions on the feather-like cotton bundles 123 filling the storage area, or the dense sewing of feather-like cotton on the fluffiness of the feather-like cotton, so that the overall fluffiness of the quilt can be better maintained. At the same time, the overall structure of the quilt is simpler, which is conducive to the mass production of quilts filled with down cotton, and greatly improves the softness, comfort, washability and recovery after washing of the down cotton filling.

[0054] like Figure 3 As shown, preferably, it includes a circumferential quilting line 14, which covers the upper flakes 11, the down cotton layer 12 and the lower flakes 13 around to fix the upper flakes 11, the down cotton layer 12 and the lower flakes 13 around so that the down cotton layer 12 has better fluffiness.

[0055] Preferably, a plurality of internal quilting lines 15 are cross-arranged inside the circumferential quilting lines 14 to fix the upper flakes 11, the down cotton layer 12 and the lower flakes 13, and further prevent the feather-like cotton bundles 123 from shifting during machine washing or water washing.

[0056] Preferably, the spacing between adjacent parallel internal quilting lines 15 is 25 to 50 cm, which enables the quilt to have both good fluffiness and washability.

[0057] Preferably, the circumferential quilting lines 14 and the internal quilting lines 15 form a checkered pattern. For example, according to the specifications of the finished product, closed single-needle quilting patterns such as 3×4, 4×5, 5×6 horizontal and vertical grids or curved grids can be selected to prevent the quilt from shifting during use or washing, and the fluffiness can be better maintained.

[0058] Preferably, the upper flakes 11 and the lower flakes 13 are ultrafine fiber flakes made of fibers with a fineness ≤10D and a fiber length ≤64mm, and the ultrafine fiber flakes are a multi-layer laid net structure, for example: the ultrafine fiber flakes are selected to have 6 to 8 layers of laid nets, combined with the control of fineness and fiber length, so that the ultrafine fiber flakes have better softness, warmth retention and structural density, and are more convenient to fix the down cotton without destroying its fluffiness.

[0059] Preferably, the ultrafine fiber flakes include fine denier fibers having a fineness of 0.5D to 6D and a fiber length of 10 to 64 mm, including ultrafine polyester staple fibers, which are beneficial to increasing the layered structure of the ultrafine fiber flakes and have good wear resistance and easy-to-wash and quick-dry properties.

[0060] Preferably, the ultrafine fiber flakes include low-melting-point fibers having a fineness of 1.5D to 3D and a fiber length of 10 to 64 mm, including polyester staple fibers that have been subjected to a high-temperature oven or an ironing process. The ultrafine fiber flakes can be fixed by the high-temperature oven or the ironing process so that the ultrafine fiber flakes will not protrude excessively during use, and can be directly used as a quilt filling material without the addition of non-woven fabric, making the overall quilt softer and more washable.

[0061] Preferably, the microfiber flakes include functional fibers, the fineness of the functional fibers is 1.5D to 6D, and the fiber length is 10 to 64 mm. Compared with the existing quilts made with single feather-like cotton as filler, which have single functionality and are inconvenient to add, since the feather-like cotton quilt contains an upper flake 11 and a lower flake 13, the functionality of the quilt can be further enriched by adding functional fibers to the microfiber flakes, and by further controlling the fineness and fiber length of the functional fibers, the fluffiness and softness of the microfiber flakes can be avoided from being affected.

[0062] Preferably, the functional fiber is polylactic acid fiber, nylon fiber, soybean fiber (modified polyamide protein fiber), regenerated cellulose fiber, lyocell fiber or acetate fiber; polylactic acid fiber has good antibacterial property, quick drying and wrinkle resistance and comfortable touch; nylon fiber has high wear resistance and moisture absorption; soybean fiber has high moisture conductivity and smoothness; regenerated cellulose fiber has good moisture absorption and air permeability; lyocell fiber has good moisture absorption, air permeability and strength; acetate fiber has good softness, moisture absorption, air permeability and easy cleaning, so the quilt can be covered with multiple functions by selecting different functional fibers.

[0063] Preferably, the filling amount of the upper flocculent sheet 11 is 10-250 g / ㎡, which can fix the down cotton layer 12 without destroying its fluffiness.

[0064] Preferably, the filling amount of the down cotton layer 12 is 10-400 g / ㎡, and the appropriate filling amount of the down cotton layer 12 can be selected according to the size and purpose of the quilt, which fully utilizes the characteristics of the feather-like cotton and is easy to produce.

[0065] Preferably, the filling amounts of each transverse cotton layer 121 and longitudinal cotton layer 122 are the same or similar, and the feather-like cotton bundles 123 are evenly spaced, so that the down cotton layer 12 formed by the transverse cotton layer 121 and the longitudinal cotton layer 122 can be more uniform, and the upper and lower feather-like cotton bundles 123 can form reliable constraints through friction to prevent deviation, and are not easy to aggregate and clump after washing.

[0066] Preferably, since the feather-like cotton is packaged in the form of a roll, the core material is a hollow plastic tube, and the down cotton is rolled on the core, similar to a fabric roll, which affects the fluffiness of the feather-like cotton to a certain extent. The feather-like cotton bundle 123 is a feather-like cotton bundle 123 that has been fluffed, and the down cotton layer 12 can have better fluffiness through the fluffy and straightened treatment, which is also convenient for production.

[0067] Preferably, the filling amount of the lower layer flakes 13 is 10-250 g / ㎡, which can fix the down cotton layer 12 without destroying its fluffiness.

[0068] Preferably, the quilt shell 2 is included and covers the outer portion of the upper flakes 11, the down cotton layer 12 and the lower flakes 13. The addition of the quilt shell 2 can further prevent the feather-like cotton from shifting, greatly improve the washability and recovery after washing of the quilt filled with the down cotton layer 12, and can be used directly without a quilt cover.

[0069] Preferably, the quilt shell 2 is a quilt shell 2 obtained by sewing processes such as inner seam, double inner seam pressing, inlaid rope, double inlaid rope pressing, single inlaid rope pressing, woven flying edge or knitted flying edge. Since there is no need to sew a quilt shell 2 with multiple storage areas, the diversity of the appearance of the quilt shell 2 can be further enriched, the firmness of the connection is improved, and it is conducive to the mass production and diversification of quilts filled with feather-like cotton.

[0070] Preferably, the quilt shell 2 is connected with the upper wadding 11, the down cotton layer 12 and the lower wadding 13 by quilting, which is simple to manufacture and avoids affecting the softness of the quilt.

[0071] Preferably, the quilting stitch length of the quilt shell 2 and the upper flakes 11, the down cotton layer 12 and the lower flakes 13 is 5 to 10 cm, which can fix the down cotton layer 12 without destroying its fluffiness.

[0072] Preferably, the quilting pattern of the quilt shell 2 and the upper flakes 11, the down cotton layer 12 and the lower flakes 13 has multiple connection points. More connection points can better fix the upper flakes 11, the down cotton layer 12 and the lower flakes 13 to maintain the overall washability of the quilt.

[0073] Preferably, the quilt shell 2 is a woven fabric or a knitted fabric. Since there is no need to sew a quilt shell 2 with multiple storage areas and the fabric does not need to be too stiff, in addition to selecting woven fabrics with good wear resistance, knitted fabrics with good softness, comfort and breathability can also be selected, which is conducive to achieving the diversification of quilt shell materials and feather-like cotton-filled quilts, and further improving softness and comfort.
