Description

Technical Field

[0001] This utility model relates to the field of down jacket technology, and in particular to a down jacket with a cross-grid pattern to prevent down leakage. Background Technology

[0002] In the conventional production process of down jackets, the risk of down leakage during stitching directly impacts product quality and user experience. Currently, most down jacket production involves filling with down first and then quilting. Because the down jacket fabric is expanded after filling, and the surface cannot be kept perfectly smooth throughout, insufficient stitch density or sparse stitches can cause the high-speed sewing needle to damage the fabric fiber structure, creating micropores of 0.1-0.3mm. This allows down fibers with a fill power of ≥600FP to leak through. This down leakage not only causes filling loss (an average loss of about 8-12g per garment per year) but also impairs the garment's warmth retention, leading to localized cold spots and a 15%-20% decrease in thermal resistance. From a user experience perspective, leaked down fibers can cause itching when in contact with the skin, and the micro-dust they contain may trigger respiratory discomfort in sensitive individuals. Laboratory tests have shown that the allergen detection rate in down-leaking garments is 3.7 times higher than in products with anti-down-leaking processes. Such quality issues can also lead to negative consumer perceptions of the brand's craftsmanship, reducing product repurchase rates. In addition, the existing down jacket structure has conventional straight or wavy quilting, and the down is fixed only in one direction. When worn, rubbed, or washed, problems such as down displacement and uneven distribution may occur, which will reduce the comfort and warmth of the down jacket after a period of wear. Utility Model Content

[0003] The purpose of this invention is to provide a down jacket with a cross-grid pattern that prevents down leakage. This invention can prevent down leakage and down leakage, and ensure the excellent comfort and warmth of the down jacket.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a down-proof cross-grid down jacket, comprising a garment body, wherein multiple quilting structures are vertically distributed along the upper edge of the garment body, the quilting structure comprising horizontal quilting and vertical quilting distributed on the horizontal quilting, the vertical quilting and the horizontal quilting intersecting to form multiple connected cross-shaped quilting units, the cross-shaped quilting units on each adjacent pair of quilting structures being staggered left and right, so that an S-shaped back-and-forth bending down filling channel is formed between each adjacent pair of quilting structures.

[0005] By adopting the above technical solution, the problem of down leakage caused by conventional down filling followed by quilting is solved. That is, quilting is performed first when the garment body is flat, so that an S-shaped down filling channel is formed between each two adjacent quilting structures. This not only ensures that the stitching forms a closed grid structure to achieve tight down locking, but also effectively avoids the risk of down leakage that is prone to occur when filling down before stitching. At the same time, it achieves a standardized operation process of stitching before filling down, taking into account the stability of the process and the quality of the finished product, avoiding down leakage and down leakage, and ensuring the excellent comfort and warmth performance of down jackets.

[0006] The present invention is further configured such that the horizontal quilting and the vertical quilting can be of a structure that extends in a straight line or in a curve.

[0007] By adopting the above technical solutions, different quilting structures can be used to achieve better down-locking function, resulting in different shapes on the surface of down jackets and more diverse styles to meet the aesthetic needs of different customers.

[0008] The present invention is further configured such that, in each pair of adjacent quilting structures, the bottom position of the vertical quilting on the upper quilting structure is higher than the top position of the vertical quilting on the lower quilting structure.

[0009] By adopting the above technical solutions, the horizontal down-blocking effect can be effectively improved, avoiding problems such as down displacement and uneven distribution that easily occur during wear, friction, or washing.

[0010] The present invention is further configured such that the width of the down filling channel remains unchanged along the extension path.

[0011] By adopting the above technical solution, not only can the distribution of down clusters be more uniform during down filling, but also after down filling, the down clusters in each down filling channel can be uniformly bound by four-way tension, resulting in better stability.

[0012] The present invention is further configured such that the vertical quilting is formed by the superposition of two upper and lower quilting lines.

[0013] By adopting the above technical solution, a quilted structure can be processed in one go by repeating the "left (right)-up-down-up-left (right)" stitching. This not only results in higher structural strength and less fraying, but also higher processing efficiency.

[0014] The present invention is further configured such that the garment body is provided with a heat-sealing structure covering the quilted structure, and the heat-sealing structure is similar in shape to the quilted structure.

[0015] By adopting the above technical solutions, the combination of quilted structure and heat-sealed structure can further improve the down-proof effect, thereby further ensuring the excellent comfort and warmth of down jackets.

[0016] The present invention is further provided that the garment body is also provided with a pocket, and the pocket opening is connected by a front flap strip and a back flap strip by a stitch. The front flap strip and the inside of the pocket opening form a first receiving cavity, and the back flap strip and the inside of the pocket opening form a second receiving cavity. The first receiving cavity contains a first rubber soft magnetic sheet, and the second receiving cavity contains a second rubber soft magnetic sheet for attracting the first rubber soft magnetic sheet.

[0017] By adopting the above technical solution, the front and back sides of the pocket opening use a magnetic fastening structure. Compared to a button structure, the pocket opening surface is smoother; compared to a zipper structure, it is less expensive; and the feel when putting your hand inside the pocket is more comfortable. In addition, the pocket opening can automatically close after the user's hand is removed, eliminating the need to fasten buttons or close zippers, making it more convenient to use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: As attached Figure 1The down-proof cross-patterned down jacket shown includes a garment body 1. The garment body 1 has multiple vertical quilting structures 2. The quilting structure 2 includes horizontal quilting 3 and vertical quilting 4 distributed on the horizontal quilting 3. The vertical quilting 4 intersects with the horizontal quilting 3 to form multiple connected cross-shaped quilting units 5. The cross-shaped quilting units 5 on each pair of adjacent quilting structures 2 are staggered to the left and right, so that an S-shaped back-and-forth bending down filling channel 6 is formed between each pair of adjacent quilting structures 2. A down filling port is reserved on one side of the garment body 1. The down filling port is connected to the corresponding down filling channel 6. After the down filling is completed, the down filling port is sealed with stitching. This design solves the problem of down leakage caused by conventional down filling followed by quilting. It involves quilting the garment body (1) while it is flat, creating an S-shaped, back-and-forth bending down filling channel (6) between each adjacent quilting structure (2). This not only ensures a closed grid structure for tight down locking but also effectively avoids the down leakage risk that occurs when filling first and then quilting. It also achieves a standardized operating procedure of quilting first and then filling, balancing process stability and finished product quality. Furthermore, the design uses a cross-stitch structure to form a three-dimensional grid unit, overcoming the limitations of conventional quilting's unidirectional fixation. Functionally, the cross-stitch structure provides bidirectional locking of the filling. Conventional quilting only fixes the down in one direction, which can lead to down displacement and uneven distribution during wear, friction, or washing. The cross-stitch structure, through grid partitioning, ensures that the down in each unit is evenly bound by four-way tension, significantly reducing down leakage. Meanwhile, the air layer formed by the grid units has a higher density insulation structure. Compared with the cold air penetration between parallel channels of conventional quilting, the three-dimensional spacing of the cross structure can extend the heat conduction path by 18%-25%, resulting in a significant improvement in insulation efficiency in actual tests. Therefore, it can prevent down leakage and down leakage, ensuring the excellent comfort and warmth performance of down jackets. In terms of craftsmanship, the cross quilting, through precise control of the stitch angle, can create a three-dimensional embossed effect with alternating light and shadow on the surface of the garment. The planar texture of conventional quilting is difficult to break through visual monotony, while the layering effect of the cross structure under light and shadow can not only enhance the product's light luxury texture, but also create differentiated styles from minimalist to complex through different combinations of stitch spacing. In high-end down jacket design, micro-pitch cross quilting (stitch spacing ≤ 3cm) can achieve a loft performance comparable to down comforters, while conventional processes at this density tend to result in stiff fabrics.

[0021] The horizontal and vertical quilting lines 4 can be straight or curved. Based on better down-locking capabilities, different quilting structures 2 can be used to create different shapes on the surface of the down jacket, resulting in more diverse designs to meet the aesthetic needs of different customers.

[0022] As attached Figure 1As shown, in each pair of adjacent quilting structures 2, the bottom of the vertical quilting thread 4 on the upper quilting structure 2 is higher than the top of the vertical quilting thread 4 on the lower quilting structure 2. This design effectively improves the lateral down-blocking effect and avoids problems such as down shifting and uneven distribution during wear or washing.

[0023] The width of the filling channel 6 remains constant along its extension path. This design not only allows for a more uniform distribution of down clusters during filling, but also ensures that the down clusters within each filling channel 6 are uniformly bound by four-way tension after filling, resulting in better stability.

[0024] It is worth mentioning that the vertical quilting 4 is formed by the superposition of two quilting lines, one above the other. Therefore, one quilting structure 2 can be fabricated in one go by repeating the stitching pattern of "left (right)-up-down-up-left (right)". The stitching path a can be found in the attached diagram. Figure 1 As shown, it not only has higher structural strength and is less prone to fraying, but also has higher processing efficiency.

[0025] Example 2: As shown in the attached document Figure 2 As shown, based on Embodiment 1, this embodiment provides a bonding structure 7 covering the quilted structure 2 on the garment body 1. The bonding structure 7 is shaped similarly to the quilted structure 2, meaning it secures the inner and outer layers of the garment body 1 together at the corresponding position of the quilted structure 2. The combination of the quilted structure 2 and the bonding structure 7 further enhances the down-proof effect, thereby further ensuring the excellent comfort and warmth of the down jacket.

[0026] Example 3: As shown in the attached document Figure 3 and attached Figure 4 As shown, based on Embodiment 1, this embodiment further includes a pocket 8 on the garment body 1. A front flap strip 10 and a back flap strip 11 are sewn together at the pocket opening 9. The front flap strip 10 and the inner side of the pocket opening 9 form a first receiving cavity 12, and the back flap strip 11 and the inner side of the pocket opening 9 form a second receiving cavity 13. A first rubber magnetic sheet 14 is installed in the first receiving cavity 12, and a second rubber magnetic sheet 15 is installed in the second receiving cavity 13 for attraction with the first rubber magnetic sheet 14. The front and back sides of the pocket opening 9 of the pocket 8 employ a magnetic adhesion structure. Compared to a button structure, the surface of the pocket opening 9 is smoother; compared to a zipper structure, it is lower in cost; and the feel when the hand is inside the pocket 8 is more comfortable. Furthermore, the pocket opening 9 automatically closes after the user extends their hand, eliminating the need to fasten buttons or close zippers, making it more convenient to use.
