Description

Technical Field

[0001] The invention relates to the technical field of bedding products, in particular to a down quilt. Background Art

[0002] Existing down quilts are mostly divided by quilting to limit the down and prevent it from shifting. However, there are the following problems: the height of the down quilt is low at the quilting line and high at other positions, making the surface uneven. After the quilt cover is put on, it is easy to curl or shift in the quilt cover. Down is easy to get stuck at the quilting line. Summary of the invention

[0003] The object of the present invention is to provide a microcapsule antibacterial duvet to solve the above technical problems.

[0004] The present invention also aims to provide a method for preparing a microcapsule antibacterial duvet, so as to prepare the microcapsule antibacterial duvet.

[0005] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0006] The microcapsule antibacterial down quilt comprises a microcapsule antibacterial surface layer, a microcapsule antibacterial back layer, and also comprises a down material filled between the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer. The down material is formed by uniformly mixing down and down-like fillings, and the down-like fillings are hot-melt connected into a mesh structure, thereby limiting the position of the down.

[0007] The present invention adds down-like fillers to the down, and utilizes the down-like fillers to support and limit the down, so that the thickness of the down quilt is relatively uniform at all places and the quilt surface is relatively flat.

[0008] Preferably, the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer contain a material of hot-melt adhesive down-like filling, the down-like filling of the upper layer of the down material is hot-melt connected to the microcapsule antibacterial surface layer while squeezing the microcapsule antibacterial surface layer, and the down-like filling of the lower layer of the down material is hot-melt connected to the microcapsule antibacterial back layer while squeezing the microcapsule antibacterial back layer. Thus, the surface layer, down material, and back layer are connected together, thereby improving the displacement between the surface layer and down material, the back layer and down material, and the down in the down material.

[0009] Preferably, the area of ​​the microcapsule antibacterial surface layer is larger than that of the microcapsule antibacterial back layer, so that the extra part of the microcapsule antibacterial surface layer can be used to cover the suture line between the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer.

[0010] The preparation method of the microcapsule antibacterial duvet comprises the following steps:

[0011] Step 1: quilt the four edges of the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer, leaving a filling opening on the foot side;

[0012] Step 2, filling the space between the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer with down material through a filling port, wherein the down material is formed by uniformly mixing down and down-like fillers;

[0013] Step 3, closing the filling port;

[0014] Step 4: Heat the down material to heat-melt the down-like filling material into a mesh structure.

[0015] Preferably, the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer contain materials of hot-melt adhesive down filling. In step 4, the down material is adsorbed toward the microcapsule antibacterial surface layer, so that the down-like filling in the upper layer of the down material squeezes the microcapsule antibacterial surface layer, and at the same time, the microcapsule antibacterial surface layer is heated to make the down-like filling hot-melt adhere to the microcapsule antibacterial surface layer; the down material is adsorbed toward the microcapsule antibacterial back layer, so that the down-like filling in the upper layer of the down material squeezes the microcapsule antibacterial back layer, and at the same time, the microcapsule antibacterial back layer is heated to make the down-like filling hot-melt adhere to the microcapsule antibacterial back layer.

[0016] Preferably, in step 4, the hot melt adsorption equipment is used for adsorption and heating at the same time;

[0017] The hot melt adsorption equipment includes an adsorption device that uses a motor to drive blades to rotate at high speed, thereby generating negative air pressure in a sealed housing, and the adsorption device is provided with an air inlet pipe;

[0018] The hot melt adsorption equipment also includes an electric heating device, which is provided with an electric heating wire. The electric heating wire is wound on a heat roller. The heat roller is connected to the pipe opening of the air inlet pipe through a rotating shaft, and the heat roller is partially exposed outside the air inlet pipe.

[0019] Beneficial effects: The present invention adopts the adsorption hot melt method to construct the mesh structure, which is completely different from the existing quilting sewing and hot pressing methods: the existing connection method is to directly connect the surface layer and the back layer together, which will cause the product surface to be uneven, thinner at the connection point, and thicker at the non-connection point. The surface layer and the back layer of the present invention are not directly connected, but connected with the help of down-like fillings. The down-like fillings play a dual role of support and connection, so that the thickness between the surface layer and the back layer can be kept basically consistent. DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0021] Specific embodiment 1, a microcapsule antibacterial down quilt, includes a microcapsule antibacterial surface layer, a microcapsule antibacterial back layer, and also includes a down material filled between the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer, the down material is formed by a uniform mixture of down and down-like filling, and the down-like filling is hot-melt connected into a mesh structure, thereby limiting the position of the down.

[0022] The preparation method of the microcapsule antibacterial duvet comprises the following steps:

[0023] Step 1: quilt the four edges of the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer, leaving a filling opening on the foot side;

[0024] Step 2, filling the space between the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer with down material through the filling port, wherein the down material is formed by uniformly mixing down and down-like filling material;

[0025] Step 3, closing the filling port;

[0026] Step 4: Heat the down material to heat-melt the down-like filling material into a mesh structure.

[0027] Specific embodiment 2, a microcapsule antibacterial down quilt, includes a microcapsule antibacterial surface layer, a microcapsule antibacterial back layer, and also includes a down material filled between the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer, the down material is formed by a uniform mixture of down and down-like filling, and the down-like filling is hot-melt connected to the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer to form a mesh structure, thereby limiting the position of the down.

[0028] The preparation method of the microcapsule antibacterial duvet comprises the following steps:

[0029] Step 1: quilt the four edges of the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer, leaving a filling opening on the foot side;

[0030] Step 2, filling the space between the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer with down material through the filling port, wherein the down material is formed by uniformly mixing down and down-like filling material;

[0031] Step 3, closing the filling port;

[0032] Step 4: heat the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer, so that the down-like filling material is hot-melted to connect the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer to form a mesh structure.

[0033] The difference between the specific embodiment 1 and the specific embodiment 2 is whether the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer contain a material that can be hot-melt bonded to the down-like filling. The microcapsule antibacterial surface layer and the microcapsule antibacterial back layer of the specific embodiment 1 do not contain a material that can be hot-melt bonded to the down-like filling. The microcapsule antibacterial surface layer and the microcapsule antibacterial back layer of the specific embodiment 2 contain a material that can be hot-melt bonded to the down-like filling. Preferably, the material that can be hot-melt bonded to the down-like filling in the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer of the specific embodiment 2 is the same as the material of the down-like filling. In the specific embodiment 2, in the process of heating the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer, not only the down-like filling is hot-melt bonded to the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer to form a mesh structure, but also the down-like fillings are partially hot-melt bonded to each other, so that the surface layer, the down material, and the back layer are connected together, thereby improving the displacement between the surface layer and the down material, the back layer and the down material, and the down in the down material.

[0034] The hot melt connection of the present invention is different from the existing heat-pressing connection method. The existing heat-pressing connection is to directly press and bond the surface layer and the back layer together, which will cause the product surface to be uneven, thinner at the heat-pressed part, and thicker at the non-pressed part. The surface layer and the back layer of the present invention are not directly bonded, but are connected with the help of down-like fillings. The down-like fillings play a supporting role, so that the thickness between the surface layer and the back layer can be kept basically consistent. Preferably, the down-like filling is hot-melted to the microcapsule antibacterial surface layer in the following manner: a 5-10mm hot-melt connection point is formed at an interval of 10cm-30cm; the down-like filling is hot-melt to the microcapsule antibacterial back layer in the following manner: a 3-8mm hot-melt connection point is formed at an interval of 15cm-30cm. The thickness of the down material in a fluffy state is 10-20 mm, the down-like filling with a thickness of 2-5 mm above the down material is hot-melt connected to the microcapsule antibacterial surface layer, and the down-like filling with a thickness of 1-3 mm below the down material is hot-melt connected to the microcapsule antibacterial back layer.

[0035] In the above two embodiments, preferably, in step 1, the area of ​​the microcapsule antibacterial surface layer is larger than the area of ​​the microcapsule antibacterial back layer. In step 1, quilting and sewing are preferably performed through the following steps: step a. quilting and sewing the four edges of the surface layer and the back layer. After suturing, the surface layer has exposed parts exposed outside the back layer on the quilt head side, left side, right side, and quilt foot side, which serve as shielding sheets. The surface layer and the quilt layer are provided with unstitched parts on the quilt foot side, which serve as filling ports. Step b. Fold the shielding sheet. After folding, one side of the shielding sheet covers the surface layer, and the other side of the shielding sheet covers the back layer, so that the quilting line at the connection between the surface layer and the back layer is covered by the shielding sheet. Step c. Except for the filling port, the remaining shielding sheets are connected to the surface layer by heat pressing on one side and the back layer by heat pressing on the other side. The present invention adds a shielding sheet at the stitching point, which can be used to effectively prevent the down from being exposed there. The present invention also limits the structure and connection method of the shielding piece, and utilizes the thickness of the shielding piece and the structure formed by hot pressing to form a structure with a certain thickness at the edge. Compared with the existing design without thickness, it can effectively ensure the consistency of the down filling density at the edge and the overall thickness of the duvet.

[0036] In the above two embodiments, preferably, in step 1, the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer are preferably prepared by the preparation method of microcapsule antibacterial home textile fabric with application number CN2020110774004 and patent name. The fabric is added with natural organic antibacterial agents, which is green and safe. More importantly, the connection strength between the antibacterial agent and the fabric is high, which makes the antibacterial effect lasting. The down-like structure connected by hot melt also has the function of fixing the microcapsules on the fabric, which can further increase the connection strength between the microcapsules and the fabric and prolong the antibacterial effect. Both the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer contain low-melting-point fibers.

[0037] In the above two embodiments, preferably, in step 2, the mass percentage of the down-like filling material to the down is not less than 20:80, and the down-like filling material may be all down-like filling material. It is particularly preferred that the down-like filling material is the down-like filling material described in the patent technology with application number CN2022115153358 and patent name A kind of down-like filling material and its production line.

[0038] In the above two embodiments, in step 4, preferably, while the down material is adsorbed toward the microcapsule antibacterial surface layer, the surface layer is heated so that the down-like filler is hot-melted and adhered to the microcapsule antibacterial surface layer. While the down material is adsorbed toward the microcapsule antibacterial back layer, the back layer is heated so that the down-like filler is hot-melted and adhered to the microcapsule antibacterial back layer. The present invention makes the down-like filler close to the layer to be adhered by adsorption, which can effectively ensure the bonding area between the down-like filler and the adhered layer, and then ensure the connection stability. More importantly, adsorption instead of pressing can effectively maintain the thickness of the down material and reduce the deformation of the down material. In step 3, the sealing of the filling port is also preferably performed by quilting and sewing first, then adsorbing the shielding sheet to the sewing position, and then fixing the shielding sheet to the microcapsule antibacterial surface layer or the microcapsule antibacterial upper layer by hot melting. When the filling port is hot-melted and sealed, the down material is also subjected to the adsorption force and will also approach the shielding sheet, thereby hot-melting and connecting the shielding sheet, increasing the difficulty of the down from being exposed there. In order to facilitate the hot melting while adsorbing, the hot melt adsorption equipment can be used. The hot melt adsorption equipment includes an adsorption device that uses a motor to drive the blades to rotate at high speed, thereby generating air negative pressure in the sealed shell, and the adsorption device is provided with an air inlet pipe. The hot melt adsorption equipment also includes an electric heating device, which is provided with an electric heating wire, which is wound on a hot roller, and the hot roller is connected to the pipe mouth of the air inlet pipe through a rotating shaft. So that the air inlet pipe moves with the movement of the hot roller. When the electric heating wire is wound on the hot roller, on the one hand, the hot roller (the hot roller uses a heat-conducting material) can be used for heat conduction, or by rolling, the relative position of the electric heating wire and the layer to be heated can be adjusted to make the hot roller more uniform everywhere. On the other hand, the electric heating wire can be used to supplement the heating of the hot roller to maintain the temperature of the hot roller. The hot roller can be fixed in the pipe mouth of the air inlet pipe, and the hot roller is partially exposed outside the air inlet pipe. There can also be two air inlet pipes, and the hot roller is fixed between the two air inlet pipes, and the lowest height of the hot roller is lower than the lowest height of the air inlet pipe. The exposed part of the hot roller can limit the position of the fabric and the air inlet pipe to prevent the air inlet pipe from scratching the fabric. This ensures that the hot roller can effectively contact the fabric. In order to reduce the wrinkles of the surface layer or the back layer caused by hot melt adsorption, a guide roller is also provided at the air inlet pipe, and the rotating shaft of the guide roller is parallel to the rotating shaft of the hot roller. At least one guide roller is provided in front of the hot roller, and one guide roller is provided behind the hot roller. The length of the guide roller is greater than the length of the hot roller, and the lowest height of the guide roller is greater than the lowest height of the hot roller, but less than the lowest height of the air inlet pipe. The hot melt adsorption equipment can also include a support bed, the microcapsule antibacterial duvet is laid on the support bed, and a support frame is provided above the support bed. The support frame includes longitudinal support frames located on both sides of the microcapsule antibacterial duvet, and the longitudinal support frame is provided with a transverse support frame that can slide along the longitudinal support frame, and the transverse support frame is provided with a vertical support frame that can slide along the transverse support frame. The air inlet pipe is fixed on the vertical support frame, or the air inlet pipe is a tubular body made of hard material, and the air inlet pipe is directly used as a vertical support.Thus, the position of the air intake pipe and the electric heating wire can be regularly controlled by using the transverse support frame and the vertical support frame, so that the hot melt position can be controlled and regular. For example, the air intake pipe and the electric heating wire can be made to run along a honeycomb-shaped route, so that the final structure formed by the hot melt connection is in the shape of a honeycomb grid. For another example, the air intake pipe and the electric heating wire can be made to run along a square grid or a diamond grid, so that the final structure formed by the hot melt connection is in the shape of a square grid or a diamond grid. When in use, first quilt and sew the four sides of the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer, leaving a filling port on the foot side. Then, place the sutured structure on the support bed, with the microcapsule antibacterial back layer at the bottom and the microcapsule antibacterial surface layer at the top. Then, fill the down material between the microcapsule antibacterial surface layer and the microcapsule antibacterial back layer through the filling port, and sew the filling port after filling. Then, after adjusting the support frame so that the air inlet pipe and the hot roller are located above the microcapsule antibacterial surface layer, the air inlet pipe is opened, the electric heating wire is started, and the adsorption device (which can adopt the structure of a vacuum cleaner) adsorbs the down material toward the microcapsule antibacterial surface layer through the air inlet pipe. Under the dual action of the electric heating wire and the hot roller, the part of the down material located at the top (i.e., the upper layer of the down material) is hot-melted and bonded to the microcapsule antibacterial surface layer. Then, the down quilt is reversed so that the microcapsule antibacterial surface layer is at the bottom and the microcapsule antibacterial back layer is at the top. After adjusting the support frame so that the air inlet pipe and the hot roller are located above the microcapsule antibacterial back layer, the air inlet pipe is opened, the electric heating wire is started, and the adsorption device (which can adopt the structure of a vacuum cleaner) adsorbs the down material toward the microcapsule antibacterial back layer through the air inlet pipe. Under the dual action of the electric heating wire and the hot roller, the part of the down material located at the top (i.e., the lower layer of the down material) is hot-melted and bonded to the microcapsule antibacterial back layer. It may also include two support plates. When the duvet is placed for the first time, one of the support plates is located between the duvet and the support bed, that is, on the side of the microcapsule antibacterial back layer. During the adsorption heating process, the support plate is preferably made of a heat-insulating material to play an isolating role to protect the support bed. When the duvet is reversed, the other support plate is first placed on top of the duvet, that is, on the side of the microcapsule antibacterial surface layer. Then, the duvet is reversed under the clamping of the two support plates, and the support plate on the side of the microcapsule antibacterial back layer is removed after the reversal. In this process, the two support plates support the duvet and limit the position of the down.
