Abstract
Description
Technical Field
[0001] This invention belongs to the field of garment manufacturing technology, specifically relating to a down jacket placket filled with three-dimensional columnar cotton strips and its preparation method. Background Technology
[0002] The placket refers to the opening, slit, or side opening at the front of a garment, primarily used for putting on and taking off clothing. In down jackets, the placket is typically filled with either down or cut cotton. The two methods are: 1. Down filling: A large amount of down is stuffed into the narrow vertical space between two layers of fabric, allowing the down's expansion to support the placket. 2. Cut cotton filling: Sheets of cut cotton such as spray-bonded cotton, imitation silk cotton, or needle-punched cotton are used as filling. These cotton sheets are cut to the shape of the placket, sandwiched between layers of fabric, and then secured with quilting.
[0003] However, these two traditional placket filling methods have many problems. First, down feathers gradually sink downwards due to gravity in the vertical structure of the placket, causing the upper part of the placket to flatten as it is worn, while the lower part becomes increasingly bulky (due to down shedding). This not only results in an uneven warmth but also makes the placket appear narrower at the top and wider at the bottom, affecting the overall aesthetics of the garment. Second, down plackets are expensive and complex to manufacture. In addition to filling with down feathers, a lining fabric is added, and buttons are sewn onto the placket. Special techniques and accessories are also required to prevent down leakage. While cut cotton filling solves the problem of down sinking, it also has significant drawbacks. Cut cotton has a sheet-like structure, resulting in a flat and lacking fullness after filling, failing to achieve a rounded and three-dimensional appearance. Furthermore, after repeated washing and wear, cut cotton is prone to clumping, deformation, poor resilience, and poor durability. Therefore, there is a lack of a down jacket placket filling solution in the field that can both prevent the filling material from settling and accumulating in the placket, maintain the full and crisp appearance of the placket, and has a simple manufacturing process.
[0004] To address the shortcomings of existing down jacket placket filling methods, the main technical problems that need to be solved include the following aspects: First, address the issue of insufficient aesthetic appeal in the finished placket. If down filling is quilted with horizontal dividing lines, uneven seam marks will appear on the surface, ruining the overall smooth and even texture of the placket; if quilting is omitted, it will result in a flattened top and bulging bottom with excessive down. Cut cotton does not require quilting, but its sheet-like support is insufficient, resulting in a flat and thin placket lacking a rounded and three-dimensional fullness. Neither of these traditional solutions can simultaneously achieve the high-quality appearance required for a seamless placket surface and an overall uniform and full look.
[0005] Secondly, the high cost of down-filled plackets needs to be addressed. To prevent down from shifting, a large amount of down needs to be stuffed into the placket. To further prevent down from shifting, a lining fabric also needs to be inserted. In addition, special processes and accessories are required to sew buttons onto the placket. All these steps increase the cost.
[0006] Third, it addresses the issues of complex production processes and poor product consistency. Traditional down filling requires multiple processes such as filling and quilting, which are complex and demand high operational skills. Furthermore, additional equipment is needed to prevent down leakage. Cut cotton filling requires cutting, spreading, and fixing the cotton, which are also cumbersome. Both methods suffer from low production efficiency, high susceptibility to human factors in product quality, and difficulty in ensuring consistent quality. Summary of the Invention
[0007] Technical problem solved: To address the above-mentioned technical problems, the present invention provides a down jacket placket filled with three-dimensional columnar cotton strips and its preparation method. The placket has a full and crisp outer tube effect and significantly simplifies the production process, and can simultaneously improve appearance quality and process efficiency while maintaining excellent warmth retention performance.
[0008] Technical solution: A down jacket placket filled with three-dimensional cylindrical cotton strips, comprising a face fabric and filling cotton strips, wherein the filling cotton strips are located inside the face fabric and are formed by winding several small cylindrical cotton strips fixed at both ends, and their length is the same as that of the placket.
[0009] Preferably, the cross-section of the filling cotton strip is elliptical, with a minor axis length of 2 cm.
[0010] Preferably, the width of the fabric is the placket width + (2~3) cm.
[0011] Preferably, the filling strip is made of long-staple cotton.
[0012] Preferably, the cylindrical cotton strip is formed by needle punching in one piece.
[0013] The preparation method of the down jacket placket filled with three-dimensional columnar cotton strips includes the following steps: Step 1: Prepare the stuffing tampons and the outer fabric; Step 2: Fold the fabric in half so that the reverse side is facing out; Step 3: Sew the beginning and end of the fabric together to secure it; Step 4: Turn the fabric right side out and insert the stuffing strips into the fabric. Step 5: Sew the unsewn side of the outer fabric to the placket of the down jacket.
[0014] Preferably, in step three, the beginning and end seam positions of the fabric are 1cm away from the outermost edge.
[0015] Beneficial Effects: This invention fundamentally solves the problem of down accumulation and migration due to gravity in the vertical placket structure by changing the filling material from a bulk granular and planar state to a three-dimensional, integral state. This allows the three-dimensional columnar cotton strips to maintain a uniform distribution without the need for quilting, while simultaneously giving the placket a full and crisp appearance and significantly simplifying the production process. Through this design, down jacket plackets can achieve simultaneous improvements in appearance quality and manufacturing efficiency while maintaining excellent warmth retention.
[0016] Specifically, the present invention has the following advantages: 1. Effectively prevents filling from settling downwards: This invention uses needle-punched, one-piece molded, three-dimensional elliptical cylindrical long-staple cotton slivers as filling. The cotton fibers inside the slivers interweave to form a stable three-dimensional network structure, preventing migration or settling under gravity. No matter how long the garment is worn, the filling remains evenly distributed throughout the placket, ensuring consistent warmth and preventing the top from becoming shriveled and the bottom from becoming bulky. This effectively solves the settling problem of traditional down-filled plackets.
[0017] 2. More aesthetically pleasing placket: The three-dimensional cylindrical cotton strips themselves have a regular, three-dimensional cylindrical shape and a smooth surface. After being encapsulated in the placket fabric interlayer, they can evenly support the placket fabric, giving the placket a full and crisp three-dimensional feel. Since the filling cotton strips are an integral structure and do not need to be divided and fixed by quilting, there are no dents or wavy patterns caused by quilting on the placket surface, maintaining the integrity and smoothness of the fabric and presenting a clean, straight, and high-end visual effect.
[0018] 3. Reduced costs and simplified process: Compared with the down placket which requires additional lining fabric, special accessories, and quilting, the process of this invention is simpler. There is no need to arrange lining fabric, special accessories, quilting, etc. in the placket making process. The reduction in the number of processes directly shortens the processing time of a single garment, reduces costs, and at the same time reduces the reliance on workers' technical experience and simplifies the process steps.
[0019] 4. Stable and reliable warmth retention: The fiber cotton material of the three-dimensional columnar cotton strip has good heat insulation properties, and the static air layer stored between its fibers can effectively block heat conduction; the internal structure of the cotton strip is uniform and stable, and will not cause local thickness reduction due to deformation during wear and use, thus ensuring that the placket area can maintain the expected warmth retention effect throughout the entire service life.

The left one is filled with down, the middle one is filled with sheet-like cut cotton, and the right one is filled with the three-dimensional columnar cotton strips of this invention. Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example 1
[0022] Using a standard placket with a finished width of 5.5cm (total width 11cm) as an example, the standardized manufacturing process includes the following steps: like Figure 2 Step 1: Select an oval cylindrical cotton strip with a short axis of 2cm and a length equal to that of the placket. Each placket is equipped with one filling cotton strip. Each filling cotton strip consists of five needle-punched long-staple cotton strips. The ends of the five cotton strips are tied together to prevent them from coming apart. The placket length is determined according to the garment length. The width of the outer fabric piece is 5.5cm, and the finished placket width is 2-3cm wider (to allow for seam allowance).
[0023] like Figure 2 Fold the placket fabric along the center line, right sides together, wrong side out (Step 2); sew the beginning and end of the placket fabric 1cm to secure them (Step 3); turn the placket fabric right side out and stuff the cotton strips into it (Step 4); align and attach the placket half-finished product with the cotton strips to the placket position of the down jacket body, and sew the unsecured side of the placket fabric together (Step 5) to complete the connection between the placket and the body; finally, install zippers, buttons, and other closure accessories at the corresponding positions on the placket to complete the down jacket placket construction.
[0024] Finished placket (see) Figure 1 ),like Figure 3 As shown, this invention fundamentally solves the problem of down accumulation and migration due to gravity in the vertical placket structure by changing the filling material from a bulk granular and planar state to a three-dimensional molded integral state. This allows the three-dimensional columnar cotton strips to maintain a uniform distribution without the need for quilting, while giving the placket a full and crisp appearance and significantly simplifying the production process. Through this design, down jacket plackets can achieve simultaneous improvements in appearance quality and manufacturing efficiency while maintaining excellent warmth retention.

No matter how long the garment is worn, the filling remains evenly distributed throughout the placket, ensuring consistent warmth and preventing the top from becoming shriveled and the bottom from becoming bulky. This effectively solves the settling problem of traditional down-filled plackets.

Since the filling cotton strips are an integral structure and do not need to be divided and fixed by quilting, there are no dents or wavy patterns caused by quilting on the placket surface, maintaining the integrity and smoothness of the fabric and presenting a clean, straight, and high-end visual effect.
[0027] 3. Reduced costs and simplified process: Compared with the down placket which requires additional lining fabric, special accessories, and quilting, the process of this invention is simpler. There is no need to arrange lining fabric, special accessories, quilting, etc. in the placket making process. The reduction in the number of processes directly shortens the processing time of a single garment, reduces costs, and at the same time reduces the reliance on workers' technical experience and simplifies the process steps.
