Description

Technical Field

[0001] This invention relates to the field of clothing label production technology, and in particular to a clothing label with see-through function and its production method. Background Technology

[0002] With the advent of the knowledge economy and the widespread application of the internet, the influx of international information has significantly impacted China's clothing market. Global fashion trends are increasingly moving towards "freedom" and "diversity," often necessitating the design of clothing labels to help consumers identify brands.

[0003] A search revealed Chinese patent publication number CN223108375U, which discloses an electronic tag for clothing, including a label plate. The label plate has a chip and a barcode on its side wall. A transparent protective shell is fixedly connected to the side wall of the label plate. The chip and the barcode are both located inside the transparent protective shell. Two arc-shaped plates are fixedly connected to the side wall of the label plate. Each of the two arc-shaped plates has a limiting groove on its side wall. The diameter of the limiting groove on the left side is larger than that on the right side.

[0004] Existing technologies similar to the aforementioned clothing labels use an arc-shaped clamping structure to fix the labels, which has problems such as easily damaging clothing, poor comfort, and affecting the overall aesthetics. Therefore, there is room for improvement. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a see-through clothing label and its production method. Its advantages include increased installation stability, no exposed fixing parts, and improved overall aesthetics.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A see-through clothing label includes an inner layer, an outer lining layer, a down layer on the side of the lining layer away from the inner layer, an outer fabric layer on the side of the down layer away from the lining layer, and a viewing window on the side of the outer fabric layer away from the down layer.

[0007] A method for producing a garment label with see-through functionality includes the following steps: Step 1: Laser drilling A 10600nm wavelength beam is generated using a laser, and the X / Y axis guide rails are moved by a CNC system to achieve a positioning accuracy of 0.1mm. The laser is then aimed at the garment arm to make a hole, and the cut edge is self-sealed by high-temperature laser melting, eliminating the need for secondary processing. The size of the hole is consistent with the size of the label. Step Two: Signage Positioning Place the clothing label inside the hole, adjust its orientation using a projection positioning system, and initially fix it from the front to ensure accurate positioning. After fixing, ensure that the gap between the label and the hole is less than 0.05mm. Step 3: High-frequency heat sealing Using a 15KW high-frequency embossing machine, TPU material is bonded to the back of the sign using composite adhesive. During bonding, the heating time, temperature, and pressure parameters are controlled to ensure uniform bonding. Once the composite adhesive has set, the sign can be installed and fixed.

[0008] The present invention is further configured such that the laser cutting requires control of the laser power, and the laser power calculation formula is: After cutting, the required cutting quality is evaluated using the following formula: Where P represents laser power, Q represents cutting quality index, v represents cutting speed, t represents fabric thickness, and k represents material constant, with different values ​​for different fabrics.

[0009] The present invention is further configured such that the laser drilling is performed using a CO2 laser machine or a fiber laser machine with a power of 50-200W, a laser drilling speed of 0.5-1.4 m / s, and a cut melting self-sealing width of 0.05-0.1 mm.

[0010] The present invention is further configured such that the high-frequency heat sealing requires calculation of the skin depth, and the calculation formula is as follows: ,in, The expression of skin-like depth, Indicates frequency, Represents relative permeability. This indicates electrical conductivity.

[0011] The present invention is further configured such that the high-frequency heat sealing pressure is 0.3-0.5 MPa and the temperature is 180-220℃.

[0012] The present invention is further configured such that the thickness of the TPU is 0.1-0.5 mm and the Shore hardness is A60-D80.

[0013] The present invention is further configured such that the high-frequency machine operates at a frequency of 27.12-40.68MHz and has an output power of 5-15KW.

[0014] The present invention is further configured such that the composite adhesive is a single-component or two-component hot melt adhesive with a melting point range of 105-120℃, and the setting time of the composite adhesive is 30-120 seconds, which can be adjusted according to the ambient temperature and humidity.

[0015] The beneficial effects of this invention are as follows: The production method of the garment label with see-through function adopts non-contact laser cutting to precisely open holes at the arm position of the garment fabric. The hole diameter is perfectly matched with the size of the label, and the cut is smooth and burr-free. The TPU material and composite adhesive are fused together by a high-frequency machine to form a strong adhesive layer. The elasticity, wear resistance and oil resistance of thermoplastic polyurethane are utilized to ensure that the label will not fall off after long-term use, which increases the firmness of the garment label installation, eliminates exposed fixing parts, and improves the overall aesthetics of the garment label.

[0020] Reference Figure 2 A method for producing a clothing label with see-through functionality includes the following steps: Step 1: Laser drilling A high-precision laser device generates a 10,600-nanometer wavelength beam, which possesses excellent penetration and stability. An advanced CNC system precisely controls the movement of the X and Y axis guides, ensuring ultra-high positioning accuracy of 0.1 mm during operation. The laser is precisely aimed at the arm of the garment for precise hole-making. Under the high temperature of the laser, the cut edges melt and self-seal, forming smooth and uniform edges without any secondary processing. Furthermore, the hole diameter is precisely calculated and adjusted to ensure a perfect match with the size of the required sign, guaranteeing a perfect fit and overall aesthetic appeal. Step Two: Signage Positioning The clothing label is placed inside the pre-designed hole, and its orientation is precisely adjusted using an advanced projection positioning system. Initial fixation is performed from the front of the label to ensure accurate positioning without any deviation. After initial fixation, further inspection is conducted to ensure the gap between the label and the hole is strictly controlled within 0.05 mm to guarantee the precision and stability of the overall installation and prevent the label from loosening or shifting during use. Step 3: High-frequency heat sealing The sign production process uses a 15KW high-frequency embossing machine. The specific steps are as follows: First, starting from the back of the sign, TPU material is firmly bonded using a composite adhesive bonding technique. During the bonding process, key parameters such as heating time, temperature, and pressure must be strictly controlled and adjusted to ensure precision at every step, guaranteeing a uniform and strong bond. After the composite adhesive has fully cured for a certain period, the sign installation is complete. This series of meticulous steps ensures the quality and durability of the sign, achieving the expected production standards.

[0021] In this embodiment, laser cutting requires controlling the laser power, and the laser power calculation formula is as follows: After cutting, the required cutting quality is evaluated using the following formula: Where P represents laser power, Q represents cutting quality index, v represents cutting speed, t represents fabric thickness, and k represents material constant, with different values ​​for different fabrics; laser drilling is performed using a CO2 laser machine or a fiber laser machine with a power of 50-200W, a laser drilling speed of 0.5-1.4 m / s, and a cut melting and self-sealing width of 0.05-0.1mm.

Indicates electrical conductivity; high-frequency heat sealing pressure is 0.3-0.5MPa, and temperature is 180-220℃.

[0023] It is worth mentioning that the thickness of TPU is 0.1-0.5mm, and the Shore hardness is A60-D80.

[0024] The high-frequency machine operates at a frequency of 27.12-40.68MHz and has an output power of 5-15KW.

[0025] The composite adhesive is a one-component or two-component hot melt adhesive with a melting point range of 105-120℃. The setting time of the composite adhesive is 30-120 seconds, which can be adjusted according to the ambient temperature and humidity.

[0026] Non-contact laser cutting is used to precisely drill holes in the garment fabric at the arm position, with the hole diameter perfectly matching the label size, resulting in a clean, burr-free cut. A high-frequency welding machine is used to fuse the TPU material with the composite adhesive, forming a strong bonding layer. Utilizing the elasticity, abrasion resistance, and oil resistance of thermoplastic polyurethane, the label is ensured to remain in place for a long time, increasing the stability of the garment label installation. There are no exposed fixing parts, improving the overall aesthetics of the garment label.
