Description

A suit chest liner and its manufacturing process Technical Field

[0001] This invention relates to the field of garment manufacturing technology, and in particular to a suit chest lining and its manufacturing process. Background Technology

[0002] Men's suits are essential attire for formal occasions, and the crispness, smoothness, and three-dimensionality of the chest area are key indicators of suit quality. For suits made of thin fabrics (such as high-count wool or linen blends), traditional chest lining treatments and stitching techniques can easily lead to several problems: First, the lining itself is prone to wrinkling, resulting in an uneven chest area and affecting aesthetics; second, thin fabrics offer poor support, causing the chest to sag and making it difficult to maintain a full, three-dimensional silhouette; and third, after wearing and washing, the garment pieces are prone to deformation, resulting in poor durability of the suit's chest contour.

[0003] Current techniques typically use a single fusible interlining or a thicker fleece lining to shape the chest area. However, for thin suits, this can result in either a stiff and unnatural appearance or an overly heavy look, losing the flow and comfort that thin suits should offer. Furthermore, traditional sewing techniques often involve stitching from the outside in, which can lead to uneven stress on the chest area, causing tension or gaps, and failing to create an elegant, fitted, ergonomic curve.

[0004] Therefore, there is an urgent need for a chest treatment process for men's thin suits that can significantly improve the flatness, firmness, three-dimensionality and durability of the chest while ensuring lightness and breathability. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a process for manufacturing a suit chest lining, comprising the following steps: pre-treating the target chest lining material to achieve a predetermined flatness, and cutting the treated target chest lining material according to a pattern to obtain an initial target chest lining; shaping the garment piece and then stitching the initial target chest lining to the garment piece so that the initial target chest lining partially covers the garment piece; covering the remaining portion of the garment piece with an fusible interfacing to form a finished chest lining; placing the finished chest lining on a chest lining mold with a convex surface and sewing from the middle of the finished chest lining while simultaneously swinging the finished chest lining along the sewing direction so that the seam lines of the finished chest lining cover at least half of the total area of ​​the finished chest lining, resulting in a shaped chest lining that conforms to the convex shape of the chest lining mold after sewing; and performing a pocket opening process on the garment piece to obtain a target pocket, and securing the target pocket with piping.

[0006] In one embodiment, the pretreatment of the target chest lining material includes: subjecting the target chest lining material to a double-roller double-press treatment; wherein the double-roller double-press treatment includes: the target chest lining material undergoing initial pressing with a first pressure roller to obtain a first flatness; and the target chest lining material with the first flatness then undergoing shaping with a second pressure roller to obtain a second flatness; wherein the rolling temperature of the first pressure roller is lower than the rolling temperature of the second pressure roller.

[0007] In one embodiment, the rolling temperature of the first pressure roller is less than or equal to 40°C, and the rolling temperature of the second pressure roller is greater than or equal to 100°C; and / or the materials of the first pressure roller and the second pressure roller are different.

[0008] In one embodiment, shaping the garment piece includes: stretching the garment piece and pre-shrinking it; cooling the pre-shrinked garment piece to obtain the garment piece of the target shape.

[0009] In one embodiment, the garment piece is subjected to periodic alternating steam injection and negative pressure adsorption, which causes the fibers of the garment piece to cool and fix rapidly after being stretched, and to obtain a predetermined internal stress distribution.

[0010] In one embodiment, when using an fusible interlining for covering, the length of the fusible interlining is stretched by 0.2-0.3 cm so that the fusible interlining forms an inner curve with the garment piece after cooling.

[0011] In one embodiment, the stitching method for stitching the initial target chest lining to the garment piece is at least one of pry stitching, adjacent stitching, and single-needle stitching.

[0012] In one embodiment, the suit chest lining manufacturing process further includes: performing a three-dimensional scan on a target user to obtain three-dimensional chest data of the target user; and performing data processing and path planning on the three-dimensional chest data to form a chest lining model that matches the three-dimensional chest data of the target user.

[0013] In one embodiment, based on the results of the data processing and path planning, the chest liner model is printed and installed using a 3D printing device.

[0014] The present invention also provides a suit chest lining, which is manufactured using the suit chest lining manufacturing process described above, and includes a garment piece, a shaped chest lining sewn together with the garment piece, and an adhesive lining bonded to the garment piece.

[0015] The beneficial effects of this invention are as follows: Pre-treatment of the target chest lining material ensures it achieves a predetermined flatness, laying a solid foundation for subsequent sewing; shaping the garment pieces significantly enhances the dimensional stability of individual pieces, preventing deformation due to stress release after sewing and during wear; and the initial target chest lining is then double-stitched with the garment pieces, ensuring the strength and stability of the chest lining structure. The finished chest lining is placed on a convex chest lining mold, and sewing begins from the center of the finished chest lining while simultaneously oscillating the finished chest lining along the sewing direction. The stitching lines of the finished chest lining cover half of its total area, resulting in a shaped chest lining that conforms to the convex shape of the chest lining mold after stitching. This creates a three-dimensional shape that matches the curve of the human chest, significantly improving the fit and aesthetics of the suit. Pockets are created by opening the garment pieces and secured with piping strips to prevent deformation. The process steps provided by this invention are clear, with well-defined parameters, facilitating standardized production, reducing reliance on individual craftsmanship, and improving production efficiency and product quality consistency.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Referring to Figures 1-3, a preferred embodiment of the present invention provides a suit chest lining manufacturing process that can be used in the production of lightweight suits. During the production of lightweight suits, due to the material characteristics (such as high-count wool or linen blends), wrinkles easily form during the chest lining manufacturing process, resulting in an uneven chest area and affecting aesthetics. Furthermore, lightweight suits have poor support, causing the chest area to easily sag and making it difficult to maintain a full, three-dimensional silhouette. The suit chest lining produced by the manufacturing process of the present invention significantly improves the flatness, crispness, three-dimensionality, and durability of the chest area while ensuring the suit remains lightweight and breathable.

[0020] Specifically, the manufacturing process of the suit chest lining of the present invention includes the following steps: Step 101: Pre-treat the target chest lining material to achieve a preset flatness, and cut the treated target chest lining material according to the pattern to obtain the initial target chest lining.

[0021] Step 102: Shape garment piece 1 and sew the initial target chest lining to garment piece 1 so that the initial target chest lining partially covers garment piece 1; cover the remaining part of garment piece 1 with fusible interfacing to form the finished chest lining.

[0022] Step 103: Place the finished breast pad on the breast pad mold 100 with the convex surface 200, and start sewing from the middle of the finished breast pad. At the same time, swing the finished breast pad along the sewing direction so that the sewing line of the finished breast pad covers at least half of the total area of ​​the finished breast pad, so as to obtain a shaped breast pad that is adapted to the shape of the convex surface 200 of the breast pad mold 100 after sewing.

[0023] Step 104: Open the pocket on the garment piece to obtain the target pocket 2, and use the piping 3 to fix the target pocket 2.

[0024] In step 101 above, the chest lining material can include charcoal lining, horsehair lining, chest cotton, and linen lining. Charcoal lining is a reinforcing material used in suits to make the chest fuller, more shapely, and rounder; it has good natural elasticity, a smooth surface, a silky feel, and low and stable shrinkage. Horsehair lining is a traditional high-end chest lining material; it is soft and elastic, conforming well to the body's curves and making the suit look more three-dimensional and crisp. Linen lining is a highly breathable material, often used in high-end bespoke suits; it not only has good breathability but also gradually sets in shape with wear. Chest cotton is relatively lightweight and is typically used in suits that prioritize a lightweight feel, making it an ideal choice for summer suits.

[0025] The chest lining material may also include fusible interlining, one side of which is regular fabric and the other side has hot melt adhesive. When the hot melt adhesive side of the fusible interlining is ironed with other fabrics, the hot melt adhesive melts under the high temperature of the iron, allowing the fusible interlining to bond with other fabrics quickly and easily. It also has the advantages of low cost and simple process.

[0026] After obtaining the initial chest lining material, chest darts, shoulder darts, etc. can be cut out from the initial chest lining material, and then the chest darts and shoulder darts can be sewn together. The above are routine operations and will not be described in detail here.

[0027] Furthermore, in step 101 above, the pretreatment of the target chest lining material includes: subjecting the target chest lining material to double-roller double-press treatment; wherein, the double-roller double-press treatment includes: the target chest lining material is initially pressed by a first pressure roller to obtain a first flatness; the target chest lining material with the first flatness is then shaped by a second pressure roller to obtain a second flatness; wherein, the rolling temperature of the first pressure roller is lower than the rolling temperature of the second pressure roller.

[0028] In this embodiment, the rolling temperature of the first pressure roller is less than or equal to 40°C, and the rolling temperature of the second pressure roller is greater than or equal to 100°C. In this embodiment, the rolling temperature of the first pressure roller is room temperature (around 26°C), and the rolling temperature of the second pressure roller is 150°C, thus obtaining a chest lining material with a preset flatness. In other embodiments, the rolling temperature of the first pressure roller can also be 30°C, 35°C, etc., and the rolling temperature of the second pressure roller can also be 110°C, 120°C, etc., without specific limitations, depending on the actual situation. Furthermore, the first pressure roller applies initial pressure of 0.5MPa to the target chest lining material at room temperature, and the second pressure roller applies hot-pressing and shaping of the target chest lining material at 0.8MPa at 150°C, thus obtaining an extremely flat lining material. It is worth noting that the preset flatness can be set according to the actual situation, without specific limitations.

[0029] Optionally, the materials of the first pressure roller and the second pressure roller can be different. For example, the first pressure roller can be made of steel, and the second pressure roller can be made of silicone, etc., so that when the target chest lining is rolled for flatness, the target chest lining can achieve the preset flatness effect. In other embodiments, the first pressure roller can also be made of other metals, such as stainless steel, and the second pressure roller can also be made of high-temperature resistant plastic, etc., without specific limitations, depending on the actual situation.

[0030] In step 102, shaping the garment piece 1 includes stretching and pre-shrinking the garment piece 1, and then cooling the pre-shrinked garment piece 1 to obtain the garment piece 1 of the target shape. The above method can be achieved by directly ironing at high temperature with a steam iron and then cooling the ironed garment piece 1 at room temperature.

[0031] Alternatively, in another preferred embodiment, the garment piece 1 can be shaped in the following manner. For example, the garment piece 1 can be subjected to periodic alternating steam injection and negative pressure adsorption, so that the fibers of the garment piece 1 are rapidly cooled and fixed after being stretched, and a predetermined internal stress distribution is obtained.

[0032] The aforementioned periodic colloid vapor injection and negative pressure adsorption of the garment piece 1 can be achieved on the roller pressing equipment used for rolling the target chest lining material. That is, the garment piece 1 is placed on the roller pressing equipment, and while rolling the garment piece 1, the equipment simultaneously injects steam into it, followed by negative pressure adsorption, resulting in rapid cooling of the garment piece 1, making the process faster and more convenient. In this embodiment, the negative pressure of the negative pressure adsorption and the cooling and shaping temperature are not specifically limited and can be set according to actual conditions. For example, the garment piece 1 sequentially passes through a first steam zone (saturated steam, time 2-3 seconds), a first negative pressure cooling zone (time 3-5 seconds), a second steam zone (slightly saturated steam, time 1-2 seconds), and a second negative pressure cooling zone (time 3-5 seconds) to complete the stress restructuring and stabilization of the fibers.

[0033] The material of the garment piece 1 mentioned above can be any one of pure wool, blended fabric, imitation wool fabric, polyester fiber, linen fabric, pure cotton fabric and corduroy fabric. The fabric can be selected and shaped according to the actual situation.

[0034] In step 102, when using the fusible interfacing for covering, the length of the fusible interfacing is stretched by 0.2-0.3 cm so that the fusible interfacing forms an inner curve with the garment piece 1 after cooling. The purpose of this setting is that after the fusible interfacing is bonded to the garment piece 1, it will gradually cool and shrink. The cooled and shrunken fusible interfacing will cause the garment piece 1 to form a natural, concave inner curved surface, thereby greatly enhancing the three-dimensionality of the garment piece 1 and its support for the chest.

[0035] Furthermore, in step 102, the stitching method for the initial target chest lining and garment piece 1 to be stitched together is at least one of pry stitch, adjacent stitch, and single-needle stitch. Preferably, adjacent stitch is used for temporary fixation first, followed by single-needle stitch for main fixation, and finally pry stitch is used for reinforcement at the edges. For example, in this embodiment, the positions of important parts such as the bust height and waistline are marked on the initial target chest lining and garment piece 1 with a pen. Adjacent stitch can be used to temporarily fix key points such as the bust height and waistline. Then, starting from the bust height, the main outline is fixed by serging outwards in a radial pattern using a single-needle sewing machine. Finally, at the edge of the chest lining, manual pry stitch is used to firmly and discreetly sew the edge to the garment piece 1.

[0036] By stitching the initial target chest lining to garment piece 1, the initial target chest lining partially covers garment piece 1, thus ensuring that the initial target chest lining and garment piece 1 have consistent tightness and shape.

[0037] In step 103, swinging the finished chest lining along the sewing direction is as follows: if the sewing direction is set to horizontal, the operator pulls the two sides of the finished chest lining and swings them to the left and right respectively, so that the finished chest lining is sewn radially from the middle to both sides, ensuring that the tension of the finished chest lining is evenly distributed from the center to the periphery, avoiding the possibility of pulling or voids in the central area caused by sewing the edges first, and further ensuring the uprightness of the suit chest lining and the fit of the human chest.

[0038] In step 104, the insert strip 3 is preferably a straight-filament insert strip 3, which is made of cotton or polyester-cotton blended interlining fabric and has a width of 1-1.5cm.

[0039] Furthermore, the manufacturing process of the suit chest lining also includes: performing a 3D scan on the target user to obtain the target user's chest 3D data; and performing data processing and path planning on the chest 3D data to form a chest lining model that matches the target user's chest 3D data.

[0040] Based on the results of data processing and path planning, the chest liner model was printed and installed using 3D printing equipment.

[0041] Through 3D scanning and parametric design, we can truly achieve "one pattern per person, one style per pattern". The chest contour is perfectly matched to the user's individual body shape. At the same time, through data processing and path planning, a chest pad model that is adapted to each user's chest can be directly customized according to individual characteristics, so that the chest pad of the final suit can perfectly fit the user's chest.

[0042] This invention also provides a suit chest lining, manufactured using the above-described suit chest lining manufacturing process, comprising a garment piece 1, a shaped chest lining sewn together with the garment piece 1, and an adhesive lining bonded to the garment piece 1. Furthermore, a webbing 3 is provided at the pocket opening. This chest lining structure possesses excellent flatness, three-dimensionality, and stability, providing a durable and crisp chest shape for the suit.

[0043] In summary: Pre-treatment of the target chest lining material ensures it achieves a predetermined flatness, laying a solid foundation for subsequent sewing. Furthermore, shaping garment piece 1 significantly enhances its dimensional stability, preventing deformation due to stress release after sewing and during wear. The initial target chest lining is then double-stitched with garment piece 1, ensuring the chest lining structure's strength and stability. Finally, the finished chest lining is placed on a chest lining mold 100 with a convex surface 200, and sewing begins from the center of the finished chest lining while simultaneously oscillating it along the sewing direction to ensure the finished product... The stitching lines of the chest lining cover half of the total area of ​​the finished chest lining, resulting in a shaped chest lining that matches the shape of the convex surface 200 of the chest lining mold 100 after sewing. This creates a three-dimensional shape that conforms to the curve of the human chest, significantly improving the fit and aesthetics of the suit. Pockets 2 are created by opening the garment pieces and secured with piping 3, effectively preventing deformation. The process steps provided by this invention are clear, and the parameters are well-defined, facilitating standardized production, reducing reliance on individual craftsmanship, and improving production efficiency and product quality consistency.
