Description

Technical Field

[0001] The invention relates to a 3D eyeletless quilted duvet and a manufacturing method thereof, belonging to the technical field of duvet manufacturing. Background Art

[0002] Currently, most down quilts on the market utilize traditional quilting methods. Traditional down products are quilted using machine quilting, or newer, fully automated computerized quilting machines must also utilize needles for de-quilting. Needle and sewing thread quilting inevitably creates needle holes, which, over time, cause more and more down to escape through the needle holes, causing long-term distress to consumers and potentially posing a respiratory hazard. Furthermore, this process requires a significant amount of labor during production. Later, some taped seamless quilting technologies have emerged. These methods apply adhesive strips to the reverse side of the quilted seam and then use high-temperature composite pressing to connect the upper and lower layers. However, their major drawbacks are flat quilting, lacking three-dimensional filling channels, a lack of down in the quilted seams, poor local insulation, and a loose connection. The finished quilt lacks a three-dimensional effect. Summary of the Invention

[0003] In view of the above-mentioned defects, the present invention aims to provide a 3D eyeletless quilted down quilt with reasonable production and good down locking effect and a production method thereof.

[0004] To this end, the technical solution adopted by the present invention is: a 3D eyelet-free quilted duvet, the duvet comprising a correspondingly arranged fabric A layer (1) and a fabric B layer (2), the inner layer of the fabric A layer (1) being divided into a plurality of continuously arranged grids A, the grids A being divided into adhesive grids A coated with adhesive and non-adhesive grids A not coated with adhesive, the adhesive grids A and non-adhesive grids A being alternately arranged; the inner layer of the fabric B layer (2) being divided into a plurality of continuously arranged grids B, the grids B being divided into adhesive grids B coated with adhesive and non-adhesive grids B not coated with adhesive, the adhesive grids B and non-adhesive grids B being alternately arranged;

[0005] When the fabric A layer (1) and the fabric B layer (2) are placed, the adhesive grid A and the non-adhesive grid B are positioned correspondingly, and the non-adhesive grid A and the adhesive grid B are positioned correspondingly;

[0006] A knitted fabric (5) is provided between the fabric layer A (1) and the fabric layer B (2), and the upper and lower surfaces of the knitted fabric (5) are alternately bonded to the bonding grid A and the bonding grid B. The non-bonded surface between the adjacent upper and lower bonded surfaces of the knitted fabric (5) forms a vertical lining (6), and a three-dimensional cavity (7) for filling down is formed between adjacent vertical linings (6);

[0007] The knitted fabric (5) is formed by interweaving warp yarns (51) and weft yarns (52); the vertical lining (6) includes a radial vertical lining (63) and a weft vertical lining (64); the three-dimensional cavity (7) is surrounded by two corresponding parallel radial vertical linings (63) and two parallel weft vertical linings (64);

[0008] The weft yarns are skipped at the positions of the radial stand lining (63), and the warp yarns are skipped at the positions of the weft stand lining (64).

[0009] Furthermore, the inner layers of the fabric layer A (1) and the fabric layer B (2) are provided with anti-down layers.

[0010] A method for making a 3D eyeletless quilted duvet is carried out according to the following steps:

[0011] 1) Production of knitted fabric (5): warp yarn (51) and weft yarn (52) are interwoven in grid areas. When interwoven to the radial vertical lining (63), the weft yarn (52) skips and is not woven. When interwoven to the weft vertical lining (64), the warp yarn (51) skips and is not woven, thereby forming vertical lining strips and filling channels.

[0012] 2) Treatment of fabric layer A (1) and fabric layer B (2): an anti-down layer and an adhesive layer are coated on the inner layers of the fabric layer A (1) and the fabric layer B (2), wherein the anti-down layer is provided on the entire surface of the inner layers of the fabric layer A (1) and the fabric layer B (2), and the adhesive layer is alternately formed into adhesive grids A and non-adhesive grids A, and adhesive grids B and non-adhesive grids B according to the size of the down quilt grids;

[0013] 3) Molding: Molding the knitted fabric (5) treated in 1) and the fabric layer A (1) and fabric layer B (2) treated in 2);

[0014] The molding positions should satisfy the following conditions: the bonding grid A of the fabric A layer (1) corresponds to the non-bonding grid B of the fabric B layer (2), and the non-bonding grid A of the fabric A layer (1) corresponds to the bonding grid B of the fabric B layer (2);

[0015] When molding in the weft direction: the radial vertical lining (63) area is reserved, and when molding in the radial direction, the weft vertical lining (64) is reserved, the fabric A layer (1) is molded in the bonded grid A area and the non-bonded grid A area is not molded, and the fabric B layer (2) is molded in the bonded grid B area and the non-bonded grid B area is not molded;

[0016] 4) The molded pieces are surrounded by three-dimensional edging, and then the down is filled into each cell through the filling channel. After filling, the filling port is sealed and the production is completed.

[0017] The advantages of the present invention are: except for the edging, each quilting grid of the entire down quilt is free of needle holes, which eliminates the historical problem of down escaping from needle holes and greatly saves labor; the knitted lock pile cloth and the standing lining have the effect of locking down down, and down will not escape after a long period of use; the three-dimensional device allows the down to store more still air, and the warmth-keeping effect is greatly improved.

The anti-down layer is arranged on the surface of the inner layer of fabric AB. The warp and weft connection points are arranged between each square of the knitted cloth, which is used to replace the machine needle quilting line of the traditional process to locate the down in each area. The 3D three-dimensional down filling channel and the three-dimensional down filling method lock the down to prevent the down from moving, and store the down in the 3D three-dimensional space of the knitted mesh layer, allowing the down to store more still air for insulation.

When interwoven to the radial lining position, the weft yarn skips and does not weave. When interwoven to the weft lining position, the warp yarn skips and does not weave, so as to form the lining strip and the filling channel. Figure 3 Knitted lock velvet and Figure 2 The A layer is composite molded, and the adhesive coating has an adhesive effect after being subjected to a high temperature of more than 120 degrees. Figure 3 3. The radial lining area is reserved and the radial Figure 3 4. The weft lining is left out, and only the gray area of ​​layer A is molded. The white area is not molded. When the white area is molded, it is molded with layer B. The order of the molded blocks is ABABAB... After this method and program operation, the structure is as follows Figure 1 Cross-section: Knitted lockpile fabric is molded in different areas on sides A and B, creating three-dimensional cavities, lining strips, and filling channels. At this point, all quilting cells are complete, eliminating the need for manual quilting and creating eyelets. Three-dimensional hemming is applied around the molded pieces. An automatic filling machine then fills each cell with the calculated down through the filling channel. Once filled, the filling port is sealed, and a three-dimensional down mattress is complete.
