Technical Field

[0001] This utility model relates to a white coat with a placket that does not require ironing, belonging to the field of clothing technology. Background Technology

[0002] A white lab coat is a common professional garment in medical, laboratory, and other professional fields. It is usually a long white coat and has practical, functional, and symbolic significance.

[0003] The prominent placket area on the chest of the white coat is crucial to its final appearance. Most coats use a heat-fused interlining on the reverse side to maintain its crispness. However, due to incomplete securing, wrinkles and deformation can occur after repeated industrial washings, requiring frequent high-temperature ironing to retain its shape. This severely impacts the coat's washability and appearance, affecting the image of medical personnel.

[0004] Currently, to maintain a clean and professional appearance, lab coats typically feature concealed pockets on the front panel to store small, important items such as pens, prescription slips, and sterile gloves, avoiding the bulky look of external pockets. Traditional concealed pockets involve multiple layers of stitching, requiring stitch treatment, resulting in complex sewing processes and low production efficiency.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This utility model addresses the shortcomings of the prior art by providing a white coat with a non-ironing placket. It uses adhesive bonding instead of sewing, reducing the sewing steps and stitching in the placket and pocket forming process. The coat is less prone to deformation when worn and maintains its crispness without the need for high-temperature ironing. This not only improves the product's wrinkle resistance and fabric smoothness but also increases production efficiency.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A non-ironing white lab coat includes a front panel with a placket piece on the inner side and a hot melt adhesive strip between the placket piece and the front panel. The front panel has a pocket opening with a hidden pocket inside. The hidden pocket includes a pocket fabric piece, an oil-proof fabric piece, and a hot melt adhesive strip arranged in sequence. The pocket fabric piece and the oil-proof fabric piece are fixed to the inner side of the front panel by the hot melt adhesive strip, and an accommodating space is formed between the pocket fabric piece and the oil-proof fabric piece.

[0009] Furthermore, the shape of the hot melt adhesive strip is the same as the shape of the placket piece.

[0010] Furthermore, the placket piece and the front piece are bonded together to form an integral placket. The left integral placket has buttonholes, and the right integral placket has buttons.

[0011] Furthermore, the outer surface of the hot melt adhesive sheet is connected to the front sheet, the middle part of the inner surface of the hot melt adhesive sheet is connected to the oil-proof cloth sheet, and the U-shaped outer periphery of the inner surface of the hot melt adhesive sheet is connected to the pocket cloth sheet.

[0012] Furthermore, the tops of the pocket fabric, the oil-proof fabric, and the hot melt adhesive sheet are flush.

[0013] Furthermore, the pocket fabric piece and the hot melt adhesive sheet have the same shape and size.

[0014] Furthermore, the transverse and longitudinal dimensions of the oil-resistant fabric sheet are smaller than those of the hot melt adhesive sheet.

[0015] Furthermore, both the hot melt adhesive strips and hot melt adhesive sheets are made of polyamide adhesive.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0017] In this invention, the placket and front piece are permanently bonded together with hot melt adhesive strips to form a rigid, integrated structure, which prevents wrinkles from the source. It is shaped at the factory and is not easily deformed after wearing. It can maintain its crispness without high-temperature ironing, saving care costs. It can also reduce sewing steps and stitch processing, reducing labor and time costs. Buttons / buttonholes are directly operated on the one-piece molded placket, improving processing efficiency.

[0018] In this invention, the pocket fabric piece and the oil-proof fabric piece are bonded to the front piece as a single structure by hot melt adhesive. The adhesive is used to replace the stitching, reducing the sewing steps and stitching in the pocket forming process, reducing labor and time costs, and also has the function of preventing oil stain penetration and extending service life.

[0019] The white coat provided by this utility model is not easily deformed when worn, greatly improving the product's wrinkle resistance and the smoothness of the fabric surface.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figures 1-3 As shown in the figure, this utility model provides a white coat with a placket that does not require ironing, including a front piece 1, a placket piece 2 on the inner side of the front piece 1, a hot melt adhesive strip 3 between the placket piece 2 and the front piece 1, and the placket piece 2 and the front piece 1 are formed into an integral placket by pressing.

[0028] The hot melt adhesive strip 3 has the same shape as the placket piece 2.

[0029] After the one-piece placket is formed, you can choose to decorate the selvage with topstitching. There are buttonholes on the left side of the one-piece placket and buttons on the right side. The buttons and buttonholes are all located on the one-piece placket, which is very convenient.

[0030] The front panel 1 has a pocket opening 4, and the inside of the pocket opening 4 has a hidden pocket.

[0031] The concealed pocket includes a pocket fabric piece 7, an oil-proof fabric piece 6, and a hot melt adhesive sheet 5 arranged sequentially. The pocket fabric piece 7 and the oil-proof fabric piece 6 are fixed to the inside of the front piece 1 by the hot melt adhesive sheet 5, and an accommodating space 8 is formed between the pocket fabric piece 7 and the oil-proof fabric piece 6.

[0032] The outer surface of the hot melt adhesive sheet 5 is connected to the front sheet 1, the middle part of the inner surface of the hot melt adhesive sheet 5 is connected to the oil-proof cloth sheet 6, and the U-shaped outer periphery of the inner surface is connected to the pocket cloth sheet 7.

[0033] The tops of the pocket fabric 7, the oil-proof fabric 6, and the hot melt adhesive sheet 5 are aligned.

[0034] The pocket fabric 7 has the same shape and size as the hot melt adhesive sheet 5, and the transverse and longitudinal dimensions of the oil-proof fabric 6 are smaller than those of the hot melt adhesive sheet 5.

[0035] The pocket fabric piece 7 and the oil-proof fabric piece 6 are bonded to the front piece 1 through a heat-sealing process, which reduces the appearance of unnecessary stitching. By setting the oil-proof fabric piece 6 as an isolation layer, oil stains can be effectively prevented from penetrating to the fabric of the front piece 1, avoiding the leaving of unsightly and difficult-to-clean oil stains.

[0036] Both the hot melt adhesive strip 3 and the hot melt adhesive sheet 5 are made of polyamide adhesive.

[0037] The specific working principle of this utility model is as follows:

[0038] In this invention, the placket and front panel are permanently bonded together with hot melt adhesive strips to form a rigid, integrated structure, which prevents wrinkles from the source. The placket is pre-shaped at the factory and is not easily deformed after wearing, saving on care costs. It also reduces sewing steps and stitch processing, lowering labor and time costs. Buttons / buttonholes are directly operated on the one-piece molded placket (without having to avoid multiple seam allowances), improving processing efficiency.

[0039] In this invention, the pocket fabric piece and the oil-proof fabric piece are bonded to the front piece as a single structure using hot melt adhesive. This method uses adhesive bonding instead of sewing threads, reducing the sewing steps and stitching in the pocket forming process, thus lowering labor and time costs. It also has the function of preventing oil stain penetration and extending service life.

[0040] Both the hot melt adhesive strips and hot melt adhesive sheets are made of polyamide adhesive, which typically has a melting point between 120°C and 180°C (depending on the model), much higher than that of industrial washing (which is generally ≤90°C). It has good heat resistance and is not easily melted or loses its stickiness.

[0041] The white coat provided by this utility model is not easily deformed when worn, greatly improving the product's wrinkle resistance and the smoothness of the fabric surface.

[0042] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
