[0047] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.
[0048] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.
[0049] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent three situations: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.
[0050] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.
[0051] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values that do not use relative terms should also be disclosed as specific values with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).
[0052] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.
[0053] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.
[0054] Based on the above, the existing down recycling method requires the down products to be cut multiple times, which makes the down easy to escape during the cutting process, thereby causing the loss of down and resulting in waste.
[0055] To resolve the above issues, please refer to Figures 1 to 10 , this embodiment provides a down recycling method, a down jacket and a folding method thereof.
[0056] See also Figure 1 , wherein the down recycling method comprises the following steps:
[0057] Folding down products;
[0058] The folded down product is compressed to reduce its volume and keep the down in a compressed state;
[0059] When the down is in a compressed state, the compressed down product is cut to open the filling cavity of the down product;
[0060] The cut down products are put into the separator to separate the down and fabric.
[0061] It is understandable that when cutting compressed down products, it takes a certain amount of time for the compressed down to stretch to a fluffy state, and the down will mainly escape in the fluffy state, so the escape of down during the cutting process can be reduced, which in turn helps to reduce the loss of down and reduce waste.
[0062] It is also understandable that folding down products can reduce their volume, making them easier to carry and store. It should be noted that discarded down products can be folded when they are collected, which can reduce the space occupied during transportation and thus save recycling costs.
[0063] Based on the above, down primarily escapes when it is in a fluffy state, and it takes time for down to expand to that state. Consequently, if the cutting time is long, more down will expand to its fluffy state, increasing down loss. Therefore, shortening the cutting time of down products is key to reducing down loss.
[0064] Therefore, folding a down product involves folding the down product in a predetermined manner so that all filling cavities overlap along the same cutting line. This arrangement allows all filling cavities to be cut simultaneously along the cutting line, thereby shortening the time required to cut the down product and further reducing down loss and waste. Furthermore, cutting all filling cavities simultaneously along the cutting line facilitates operation. It should be noted that the above-described folding method can be designed based on the actual application scenario; it only needs to ensure that all filling cavities of the down product can be easily cut simultaneously, and this will not be elaborated on here.
[0065] To ensure the compression effect of the down product, in this embodiment, compressing the folded down product includes:
[0066] Use a press to compress the folded down product; or
[0067] The folded down products are placed in a vacuum environment and compressed by reducing the air pressure.
[0068] It should be noted that the vacuum environment can be provided by vacuum compression bags, vacuum packaging machines and other equipment. The pressing machines include balers, compressors and other automated equipment, which will not be described in detail.
[0069] To enhance the convenience of cutting down products, in this embodiment, cutting the compressed down products includes using a cutting device to cut the compressed down products along a cutting line. It should be noted that the cutting device can be selected based on the actual application scenario, such as a fabric cutting machine, a circular knife shearing machine, etc. Of course, for some small-sized down products, manual cutting with scissors can also be performed without using a cutting device, which will not be described in detail.
[0070] See also Figure 2 and Figure 3 The down jacket provided in this embodiment can be recycled using the above-mentioned down recycling method. The down jacket includes a back piece 1, a left front piece 2, and a right front piece 3. The left front piece 2 and the right front piece 3 are respectively connected to the left and right sides of the back piece 1, and the left front piece 2 and the right front piece 3 can be adapted to be connected. The down jacket also includes a plurality of filling cavities. The back piece 1, the left front piece 2, and the right front piece 3 are each provided with a plurality of filling cavities arranged in sequence, and all the filling cavities located on the back piece 1, the left front piece 2, and the right front piece 3 are transversely connected. The back piece 1, the left front piece 2, and the right front piece 3 form a collar. The down jacket also includes a collar 4 connected to the collar. The collar 4 includes at least one filling cavity, and the filling cavity is connected along the circumference of the collar 4. The back piece 1 and the left front piece 2 form a left cuff, and the down jacket also includes a left sleeve 5 connected to the left cuff. The left sleeve 5 includes a plurality of filling cavities arranged in sequence, and the plurality of filling cavities pass through the circumference of the left sleeve 5. The back piece 1 and the right front piece 3 form a right cuff, and the down jacket also includes a right sleeve 6 connected to the right cuff. The right sleeve 6 includes a plurality of filling cavities arranged in sequence, and the plurality of filling cavities pass through the circumference of the right sleeve 6.
[0071] With this arrangement, all of the down jacket's filling cavities are at least partially arranged horizontally, making it easier to fold all of the down jacket's filling cavities onto the same cutting line, facilitating subsequent cutting and thus improving the efficiency of down recycling. It is worth noting that, except for the down filling in the filling cavities, all other components of the down jacket are made of a single nylon material (such as a thermoplastic polymer material), facilitating the reuse of recycled materials.
[0072] See also Figures 4 to 10In addition, the down jacket folding method provided in this embodiment is used to fold the above-mentioned down jacket, and the down jacket folding method includes the following steps:
[0073] Fold the left front garment piece 2 in half along the left edge of the back garment piece 1;
[0074] Fold the right front garment piece 3 in half along the right edge of the back garment piece 1;
[0075] Folding the back garment piece 1 vertically in half along the middle of the back garment piece 1;
[0076] The back garment piece 1 is folded in half transversely along the middle portion of the back garment piece 1 .
[0077] It is understandable that folding a down jacket according to the above folding method can fold the down jacket into a more regular block, which is easier to carry and store. In addition, folding a down jacket according to the above folding method can fold all the filling cavities of the down jacket onto the same cutting line, which is easier to cut later.
[0078] Specifically, the down jacket also includes a storage bag 7, which is located on the lower inner side of the left front panel 2 or the right front panel 3. This arrangement allows the down jacket to be stored and compressed within the built-in storage bag 7, which not only helps reduce down recycling costs but also eliminates the need for an external compression device, making compression easier. Furthermore, the storage bag 7 can also be used to store the down jacket during normal use, enhancing its convenience.
[0079] Correspondingly, the down jacket folding method further includes the following steps:
[0080] After the rear garment piece 1 is folded in half transversely, the storage bag 7 is turned over to cover the outside of the folded down jacket, so as to store and compress the folded down jacket.
[0081] With such arrangement, the folded down jackets can be stored in the storage bag 7, making subsequent cutting more convenient.
[0082] To improve cutting accuracy, a vertical cutting line 8 is provided in the middle of the inner side of the storage bag 7. When cutting, the compressed down jacket is cut along the cutting line 8, thereby opening all its filling cavities. It should be noted that after folding the down jacket using the above-mentioned folding method, the cutting line 8 originally located on the inner side of the storage bag 7 is flipped to the outermost side.
[0083] Generally speaking, the collar 4 is small in size and tends to be tilted to one side after folding. That is, the collar 4 tends to be not on the cutting line 8 after folding, resulting in the down filling cavity of the collar 4 not being cut at one time, thereby affecting the down recovery efficiency.
[0084] For this reason, the down jacket folding method further comprises the following steps:
[0085] After folding the back piece 1 vertically, fold the left front piece 2 diagonally upward from the middle of the left front piece 2 to open the collar 4; or
[0086] After the rear garment piece 1 is folded vertically, the right front garment piece 3 is folded upward from the middle of the right front garment piece 3 to open the collar 4.
[0087] With such arrangement, the collar 4 can be opened to ensure that it can extend to the cutting line 8, thereby ensuring that all the filling cavities of the down jacket can be cut in sequence, thereby ensuring the down recovery efficiency.
[0088] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
