Description

Technical Field

[0001] This utility model relates to the field of clothing technology, and in particular to a detachable collar for a faux two-piece coat. Background Technology

[0002] In the field of apparel technology, layered jackets have become a popular product category in the current market due to their advantages of combining a sense of style and versatility in dressing. Among them, the detachable collar design is widely used in various outerwear products such as suits, jackets, and down jackets because it can flexibly switch collar styles and adapt to different occasions.

[0003] However, the detachable collar design of existing two-piece jackets still has many shortcomings and cannot fully meet the core needs of users: First, the connection stability of detachable parts is insufficient. The double fastening system of buttons and Velcro commonly used in existing technology is prone to loosening and deformation of buttonholes after frequent disassembly. Especially when wearing layered jackets in winter, the connection part is prone to shifting, affecting the wearing effect. Second, the wearing experience and collar shape maintenance are not good. Some products have unreasonable material layer design, and excessive layering can easily lead to an overall bulky and fat appearance. In addition, the internal filling of the collar is prone to shifting and clumping, and the collar shape lacks effective support. After long-term use, it is prone to collapse and deformation. The side of the collar that contacts the skin lacks a skin-friendly and breathable design, which can easily cause friction, discomfort and stuffiness after long-term wear.

[0004] Therefore, those skilled in the art have provided a detachable collar for a double-layered coat to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a detachable collar for a faux two-piece coat. This design utilizes a snap-fit ​​connection structure with buttons and buttonholes, combined with a serrated edge on the connecting fabric and an equidistant distribution of buttons along the shoulder and neck curve. This effectively solves the problems of loosening, displacement, and buttonhole deformation in existing detachable components, ensuring a stable and evenly distributed connection between the collar and the coat body. It also allows for convenient and efficient assembly and disassembly. The first material enhances the component's layered design of "outer protection—core—inner reinforcement" and targeted material selection. The microfiber abrasion-resistant reinforcement layer enhances the durability of easily worn areas of the collar, while the hollow yarn fabric provides both lightness and warmth without bulkiness. The breathable non-woven fabric filling layer effectively prevents the filling from shifting and clumping. Combined with the hollow yarn core layer of the collar and the skin-friendly and breathable bamboo fiber cushioning layer, this design ensures a consistently neat and crisp collar shape that is not prone to collapse, while also improving skin comfort and reducing friction, discomfort, and stuffiness.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A detachable collar for a faux two-piece coat includes a collar stand and a coat body. The upper end of the collar stand is provided with a collar, and the lower end of the collar stand is provided with a connecting fabric. The upper end of the coat body is provided with a round neckline. Multiple buttons are arranged around the inner wall of the round neckline. Multiple buttonholes are provided on the connecting fabric. Each of the buttons is snapped into a corresponding buttonhole. A first material lifting component is provided inside the collar, and a second material lifting component is provided inside the collar stand. Through the above technical solution, the collar and the upper part of the collar stand are fixed by sewing, and the connecting fabric is sewn to the lower part of the collar stand to form a complete detachable collar unit. The buttons of the round neck are sewn through the fabric and fixed, and are precisely aligned with the buttonholes on the connecting fabric to achieve detachable assembly. This allows for quick disassembly and assembly of the collar and stable fixation, enabling the coat to flexibly switch between different collar styles to suit various wearing scenarios, improving the product's practicality and styling flexibility. The first and second material lifting components are fixed to the collar and collar stand fabric by dot stitching or partial stitching to prevent interlayer displacement. While not changing the core detachable function, the overall performance is optimized.

[0007] Furthermore, the first material lifting component includes a first core material layer, a wear-resistant reinforcing layer is provided on the outer side of the first core material layer, and a filling and fixing layer is provided on the inner side of the first core material layer; Through the above technical solution, a layered design of "outer protection - core - inner reinforcement" is adopted, allowing each material layer to perform its function and optimize the collar's performance through reasonable cooperation. The wear-resistant reinforcement layer is sewn to the outside of the first core material layer along the collar tips and edges. The filling and fixing layer wraps the internal filling and is attached to the inside of the first core material layer and fixed with uniform stitches, forming a stable three-layer structure. This layered structure not only retains the core function of the collar, but also enhances the durability of easily worn parts through the wear-resistant reinforcement layer. The filling and fixing layer effectively prevents the internal filling from shifting and clumping, allowing the collar to maintain a regular shape for a long time, significantly improving the wearing experience and product lifespan.

[0008] Furthermore, the second material enhancement component includes a second core material layer, and a skin-friendly and breathable cushioning layer is provided on the side of the second core material layer away from the round neckline; Through the above technical solution, the support function and skin-friendly requirements of the collar seat are addressed by utilizing the complementary functions of two-layer materials, taking into account both structural stability and wearing comfort. The skin-friendly and breathable cushioning layer is fixed to the inside of the second core material layer through full-width fitting sewing, ensuring no gaps between the layers and conforming to the shape of the collar seat. The skin-friendly and breathable cushioning layer is in direct contact with the human body, reducing friction and discomfort, achieving a dual guarantee of "support and comfort" and improving the experience of wearing for a long time.

[0009] Furthermore, the wear-resistant reinforcing layer is made of microfiber cloth, the first core material layer is made of hollow yarn fabric, and the filling and fixing layer is made of breathable non-woven fabric. Through the above technical solutions, based on the inherent characteristics of each material, the needs of collars in terms of wear resistance, shape retention, and breathability are specifically addressed. The microfiber fabric is not prone to unraveling after being sewn to the first core material layer. The hollow yarn fabric does not affect breathability after being bonded to the filling and fixing layer. The breathable non-woven fabric can be well bonded to the internal filling and the first core material layer. After sewing, the original properties of each material are not damaged. This effectively improves the wear resistance of the collar edge of the microfiber fabric and prevents pilling and damage. The hollow yarn fabric makes the collar both lightweight and warm without being bulky. The breathable non-woven fabric ensures internal air circulation and fixes the filling, allowing the collar to maintain its crisp shape for a long time, thus comprehensively improving the practicality and wearing experience of the product.

[0010] Furthermore, the second core material layer is made of hollow yarn fabric, and the skin-friendly and breathable cushioning layer is made of bamboo fiber fabric. The above technical solution utilizes the complementary properties of the structural stability of hollow yarn fabric and the skin-friendly breathability of bamboo fiber fabric to meet the functional requirements of the collar stand. Furthermore, the bamboo fiber fabric and hollow yarn fabric have good sewing compatibility, and the seams are less likely to develop hard edges. The tight fit between the layers does not affect the support and comfort of the collar stand. The hollow yarn fabric provides stable support for the collar stand, preventing the collar shape from collapsing due to frequent disassembly and assembly, while the bamboo fiber fabric enhances skin-friendly comfort, absorbs moisture and is breathable, preventing a stuffy and sticky feeling after prolonged wear, making the collar stand both durable and comfortable.

[0011] Furthermore, the connecting fabric is made of a thin, double-layered bulk material; The above technical solution utilizes the structural characteristics of a lightweight double-layer body material, balancing the structural strength and fit of the connecting fabric to meet the requirements of buckle connections. The connecting fabric is fixed to the lower end of the collar stand by full-circumference sewing. After the buttonholes are opened, the edges are treated with an overlocking process to ensure structural stability when fastened with buttons. The lightweight nature of the connecting fabric allows it to fit tightly against the round neckline of the coat without fabric accumulation, maintaining a neat appearance. The double-layer structure enhances the durability and tear resistance of the connecting fabric, enabling it to withstand the stress of repeated button fastening, preventing damage and deformation, and extending the service life of the detachable structure.

[0012] Furthermore, the multiple buttons are equidistantly distributed along the curvature of the human shoulder and neck, with a spacing of 5cm between two adjacent buttons; By employing the above technical solutions, following ergonomic principles, and conforming to the natural curvature and stress characteristics of the shoulders and neck, the evenly distributed fastening points achieve stress balance. The equidistantly distributed buttons precisely correspond to the buttonholes on the connecting fabric, ensuring that each connection point experiences uniform stress after fastening, avoiding localized stress concentration. This allows the detachable collar to fit more snugly after assembly, without shifting or feeling tight. The uniform stress distribution enhances connection stability, preventing damage to a single part due to excessive stress, while also making the assembly and disassembly process smoother, further optimizing the overall user experience.

[0013] This utility model has the following beneficial effects: This utility model proposes a detachable collar for a faux two-piece coat.
