Description

Technical Field

[0001] The invention relates to the technical field of clothing mechanics, and in particular to a shirt collar structure and a molding process. Background Art

[0002] Traditional shirt collar production processes mostly use sewing and splicing of multiple layers of fabric. This process has many defects: the sewing process is prone to seam distortion and uneven stitch length, resulting in an unsightly collar appearance, and the sewing thread may break after long-term use, causing the collar to deform and loosen. During daily washing, due to the different shrinkage rates of the fabrics and the uneven force at the sewing point, the collar is prone to wrinkling and deformation, affecting the overall wearing effect of the shirt. However, traditional processes have bottlenecks in production efficiency, and manual operations are cumbersome, making it difficult to achieve large-scale rapid production. Summary of the invention

[0020] In order to make the purpose, technical scheme and advantages of the present invention clearer, the following is a further detailed description of a shirt collar structure and molding process proposed by the present invention in combination with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, please refer to the accompanying drawings. It should be noted that the structure, proportion, size, etc. illustrated in the drawings of this specification are only used to match the content disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effect and purpose that can be achieved by the present invention.

[0021] See also Figure 1 The shirt collar structure of this embodiment includes a collar surface layer 1, a collar lining layer 2, and a hot melt adhesive layer 3 arranged between the collar surface layer 1 and the collar lining layer 2. The hot melt adhesive layer 3 can melt quickly when heated, thereby generating viscosity and tightly fitting with the collar surface layer 1 and the collar lining layer 2 respectively.

[0022] Please continue reading Figure 2 The molding process of this embodiment is applied to the above-mentioned shirt collar structure, and the process includes the following steps: Step 1: Pre-production preparation, including selection and cutting of collar surface layer 1, collar lining layer 2 and hot melt adhesive layer 3.

[0023] For the collar surface layer 1 and the collar lining layer 2, suitable fabrics are selected according to the style and quality requirements of the shirt. For example, for formal shirts, high-count pure cotton fabrics are often selected to ensure the stiffness and comfort of the collar. During the selection process, the warp and weft density, strength, color fastness and other indicators of the fabrics need to be strictly tested.

[0024] For the hot melt adhesive layer 3, the melting point, viscosity, water washability and other characteristics of the hot melt adhesive film are key considerations. The melting point of the hot melt adhesive layer 3 is 100-130°C, and it is a hot melt adhesive film with high viscosity and good water washability. The thickness of the hot melt adhesive layer 3 is determined according to the design requirements of the collar, and the thickness is 0.1-0.3mm. Too thin will easily lead to problems such as insufficient adhesion and insufficient penetration, and too thick will easily lead to problems such as reduced elasticity and affected product feel.

[0025] For the cutting process, the cutting errors of the collar surface layer 1 and the collar lining layer 2 relative to the sample size are within ±0.2 mm, the cutting shape of the hot melt adhesive layer 3 is consistent with the sample shape, and the edge protrudes uniformly from the sample edge by 1 cm to reserve for the ultrasonic knife die to facilitate punching.

[0026] Step 2: Hot melt bonding operation.

[0027] Step 2.1: Equipment selection and parameter setting.

[0028] A hot melt laminating machine with precise temperature control function is used. This type of heating plate can evenly transfer heat to the hot melt adhesive film to melt it. The temperature uniformity error of the heating plate of the equipment is controlled within ±2°C. In the parameter setting, the temperature of the equipment is set to within ±5°C of the melting point of the hot melt adhesive layer 3, and the pressure of the equipment is set to 150-250kpa.

[0029] Step 2.2: Lamination process.

[0030] The collar surface layer 1 is laid flat on the workbench of the hot melt laminating machine, and then the hot melt adhesive layer 3 is accurately placed on the collar surface layer 1, and then the collar lining layer 2 is covered on the hot melt adhesive layer 3. The hot melt laminating machine is started to perform the laminating process, and the hot melt adhesive layer 3 is rapidly melted and penetrated into the fibers of the collar surface layer 1 and the collar lining layer 2 under the action of heat and pressure, achieving preliminary laminating. During the laminating process, the laminating time is 5 to 10 seconds.

[0031] Step 3: Ultrasonic punching operation.

[0032] Step 3.1: Equipment selection and parameter setting.

[0033] Regarding the selection of ultrasonic punching machine equipment, the frequency of the equipment is 20-40kHz, which can generate high-frequency vibration energy to better integrate the fabrics of the collar surface layer 1 and the collar lining layer 2 with the hot melt adhesive layer 3. At the same time, the transducer and amplitude transformer of the ultrasonic laminating machine should have high precision to ensure uniform energy output. The power of the ultrasonic punching machine equipment is 300-800w, which is adaptively adjusted according to the size and thickness of the collar. In addition, according to the shape and design requirements of the collar, the path parameters of ultrasonic punching and laminating are set.

[0034] Step 3.2: Punching process.

[0035] The collar that has been hot-melt bonded in step 2 is placed on the workbench of the ultrasonic punching machine, and the ultrasonic punching machine is started for pressing. During the punching process, the pressing speed is 5-15 mm / s. The high-frequency vibration of the ultrasonic wave causes friction between the hot-melt adhesive layer 3 and the fabric molecules of the collar surface layer 1 and the collar lining layer 2, and improves the bonding strength of the collar, making the collar surface smoother.

[0036] Step 4: Post-processing.

[0037] After the ultrasonic pressing is completed, the formed collar is placed squarely in the placement area through natural cooling to ensure that the shape of the collar is stable and cooled and shaped.

[0038] Furthermore, the collar quality is comprehensively tested in a variety of ways. This includes visually inspecting the appearance of the collar to see if there are wrinkles, glue overflow, etc. A tensile tester is used to test the bonding strength of the collar, and the tensile value must meet the national standard. A thickness gauge is used to measure the thickness of each part of the collar, and the thickness deviation is controlled within ±0.05mm. The above methods further ensure the quality of the collar structure after molding.

[0039] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-described embodiments only express several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, several variations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
