Description

Technical Field

[0001] The invention relates to the technical field of clothing processing, in particular to a structure for clothing cuffs and hems and a manufacturing method thereof. Background Art

[0002] In clothing production, the design and production of cuffs and hems are crucial to the overall appearance and wearing comfort of clothing. The traditional method of making cuffs and hems usually adopts multi-layer fabric sewing or double-layer hot pressing wrinkling treatment, which has many disadvantages. Multi-layer fabric sewing will increase the thickness and weight of the clothing, affecting the flexibility and comfort of wearing, and will cause problems such as delamination and unthreading during use, reducing the durability of the clothing. However, traditional wrinkling methods often make it difficult to achieve a uniform and stable pleating effect, resulting in the appearance of cuffs and hems that is not beautiful enough, and may affect their elasticity and stretchability, making the wearer feel restricted when moving.

[0003] In addition, there are also deficiencies in the existing process technology. In the application of cuffs and hems, the existing composite technology, due to improper selection and use of double-sided adhesive, will lead to loose bonding with the fabric, or the adhesive layer will age and the viscosity will decrease during use. The process is complicated and the cost is high.

[0004] At the same time, due to the lack of precise wrinkle control technology, there are deficiencies in production efficiency and quality stability. The double-layer wrinkle elastic band cannot perfectly match the fabric, and it is impossible to achieve uniform elastic distribution and good wrinkle effect synergy.

[0005] As for the processing of the lower edge, due to the unreasonable selection and wrapping method of the elastic knitted belt, problems such as curling and unthreading are prone to occur, which affects the overall quality and aesthetics of the cuffs and hem. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a structure for cuffs and hems of clothing and a manufacturing method thereof, so as to solve one or more problems in the prior art.

[0007] To achieve the above object, the technical solution of the present invention is as follows: A structure for cuffs and hems of clothing, comprising a structural layer, the structural layer consisting of a fabric layer, an adhesive layer and an elastic layer, the two ends of the adhesive layer being respectively connected to the fabric layer and the elastic layer; the structure also comprises an elastic layer, the elastic layer symmetrically covering the structural layer at one end of the structural layer.

[0008] A manufacturing method, which is applied to the above-mentioned structure for cuffs and hems of clothing, comprises the following steps: Material preparation, including material preparation for the structural layer and the elastic layer; Making of the structural layer; The connection between the elastic layer and the structural layer; Quality inspection and finished product finishing.

[0009] Furthermore, the elastic elongation of the material of the elastic layer is 100% to 300%, and the elastic recovery rate is greater than 90%.

[0010] Furthermore, the manufacturing of the structural layer includes the following steps: Processing of the bonding layer; The bonding of the fabric layer and the adhesive layer; The adhesive layer and the elastic layer are bonded again.

[0011] Furthermore, the adhesive layer is processed by molding the adhesive layer into evenly spaced adhesive areas and non-adhesive areas, wherein the width of the adhesive area is 2 mm, and the width of the non-adhesive area is 3 mm.

[0012] Furthermore, the re-bonding of the adhesive layer and the elastic layer also includes a wrinkling process, and the wrinkling process includes heat-setting wrinkling and manual wrinkling, and the shapes after wrinkling correspond to the adhesive area and the non-adhesive area respectively.

[0013] Furthermore, the lamination of the fabric layer and the adhesive layer, the re-lamination of the adhesive layer and the elastic layer, and the heat-setting wrinkling are all formed by a cold and hot pressing dual-temperature process.

[0014] Furthermore, in the hot and cold pressing dual-temperature process, during the hot pressing process, the temperature is 140-150°C, the time is 20-25s, and the pressure is 3-3.5kg; during the cold pressing process, the temperature is 16-20°C, the time is 8-10s, and the pressure is 3.5kg.

[0015] Furthermore, the elastic layer is connected to the structural layer by wrapping the end of the structural layer, and the length L of the wrapping on the surface of the structural layer is 1 cm.

[0016] Furthermore, the covering is sutured by elastic stitches, and the distance between the suture end face and the end face of the elastic layer covering the structural layer is 1.5 mm.

[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (I) Through the selection and processing of the structural layer and elastic layer materials, the cuff hem is made softer and more comfortable in contact with the human skin, reducing friction and discomfort, and has good elasticity and stretchability, which can better adapt to the movement and posture changes of the human body, and improve the wearing comfort and fit of the clothing. Especially during exercise or frequent activities, it can provide the wearer with a better wearing experience.

[0018] (ii) The unique wrinkling process achieves a rich, uniform and beautiful wrinkling effect, adding a unique visual effect and fashion sense to the cuff hem. The design of the elastic layer not only improves the aesthetics, but also makes the overall shape of the cuff hem more refined and smooth.

[0019] (iii) Through the application of adhesive layer and the reasonable configuration of elastic layer, the structure of cuff hem is more stable and not easy to delaminate, derail or deform. In the process of long-term use, it can maintain good shape and performance, extending the service life of the garment. BRIEF DESCRIPTION OF THE DRAWINGS

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 by the accompanying drawings of this specification are only used to match the content disclosed in the specification, so that people familiar with this technology can 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, without affecting the effect that the present invention can produce and the purpose that can be achieved, should still fall within the scope of the technical content disclosed by the present invention.

[0026] See also Figures 1 to 3 The structure for the cuff and hem of clothing of this embodiment comprises a structural layer 1, which is composed of a fabric layer 101, a bonding layer 102 and an elastic layer 103, and the two ends of the bonding layer 102 are respectively connected to the fabric layer 101 and the elastic layer 103. The structure also comprises an elastic layer 2, which symmetrically covers the structural layer 1 at one end of the structural layer 1.

[0027] Please continue reading Figure 4 The manufacturing method of this embodiment is applied to the structure for the cuffs and hem of clothing according to the embodiment of claim 1, and comprises the following steps: Step 1: Material preparation, including material preparation of structural layer 1 and elastic layer 2.

[0028] The fabric layer 101 with suitable properties is selected, and according to the design requirements and product performance indicators, preferably the fabric that meets the use requirements of the cuff hem in terms of softness, elasticity, wear resistance, etc. is used. Necessary quality inspections are carried out on the fabric's material, thickness, width, color, softness, elasticity, wear resistance, shrinkage rate and other indicators to ensure that the fabric meets national standards and industry specifications and is flawless and free of defects.

[0029] For the adhesive layer 102, it is preferred to use a special double-sided adhesive with high viscosity, temperature resistance, water resistance and good flexibility. The viscosity strength, thickness, width and other parameters of the double-sided adhesive can be determined according to the material and performance of the single-layer fabric and the external rubber band. If it is a customized double-sided adhesive, sampling tests can also be carried out to test its viscosity, peel strength, aging resistance and other indicators to ensure its stable and reliable quality.

[0030] For the elastic layer 103, it is preferred to select external elastics with suitable specifications and elastic properties, and the elastic coefficient of the elastics should be accurately tested to ensure that it can meet the use requirements of the cuff hem during stretching and recovery.

[0031] Furthermore, for the elastic layer 2, an elastic knitted belt with high elasticity, softness, good moisture absorption and air permeability, and skin affinity is preferred to ensure that it can provide sufficient elastic support without causing pressure on the skin, and at the same time match the overall style of the cuff hem. If necessary, the elasticity, thickness, width, color, softness and other indicators of the elastic knitted belt are strictly screened to ensure that it meets the design requirements and quality standards. The elastic coefficient, thickness, width and other parameters of the elastic knitted belt are strictly tested and screened. In this embodiment, the parameters mainly include the following aspects: In terms of size: the width of the bottom hem of the clothing cuffs is 2cm, the thickness is 0.1-0.3cm for thinner ones, and can reach 0.5cm for thicker ones. The thinner ones are used for clothing made of light fabrics, and the thicker ones are used for cuffs made of thick fabrics or that require three-dimensional decoration.

[0032] Elasticity: the elastic elongation of the material of the elastic layer 2 is 100% to 300%, and the elastic recovery rate is greater than 90%, so as to ensure that it can basically recover after stretching.

[0033] Material: The main component is spandex, the spandex content is between 50% and 70%, with good elasticity, and the rest is nylon, etc. Nylon makes the knitted belt more wear-resistant. It is preferred to use 20 to 40 yarns. The higher the yarn count, the finer the yarn, and the smoother the surface of the knitted belt.

[0034] Step 2: Production of structural layer 1.

[0035] Step 2.1: Processing the bonding layer 102 .

[0036] In a clean and dry working environment, the adhesive layer 102 is cut by a laser cutting machine into evenly spaced adhesive areas 1021 and non-adhesive areas 1022, wherein the width of the adhesive area 1021 is 2 mm, and the width of the non-adhesive area 1022 is 3 mm. Preferably, in this embodiment, the width of the adhesive layer 102 is 6 cm.

[0037] Step 2.2: Laminating the fabric layer 101 and the adhesive layer 102 .

[0038] Before laminating, the fabric layer 101 is subjected to steam ironing pre-shrinkage treatment to ensure the dimensional stability and surface flatness of the fabric, so as to prepare for the subsequent processing steps. By manual operation, the adhesive layer 102 is evenly and evenly laminated on the surface of the fabric layer 101 that has been pre-shrunk by steam, and is aligned at the outer edge of the cuff hem. During the laminating process, it is formed by a hot and cold pressing dual-temperature process, wherein the temperature during the hot pressing process is 140-150°C, the time is 20-25s, and the pressure is 3-3.5kg, while the temperature during the cold pressing process is 16-20°C, the time is 8-10s, and the pressure is 3.5kg. Ensure that the fabric layer 101 and the adhesive layer 102 are tightly fitted without bubbles or wrinkles. Improve the firmness and uniformity of the fit.

[0039] Step 2.3: Re-bonding of the adhesive layer 102 and the elastic layer 103 .

[0040] The other side of the adhesive layer 102 is bonded to the elastic layer 103 by a hot and cold pressing process, wherein the temperature during the hot pressing process is 140-150°C, the time is 20-25s, and the pressure is 3-3.5kg; the temperature during the cold pressing process is 16-20°C, the time is 8-10s, and the pressure is 3.5kg, thereby forming a stable and integrated structural layer 1. Furthermore, the re-bonding of the adhesive layer 102 and the elastic layer 103 also includes a wrinkling process, which includes heat-setting wrinkling and manual wrinkling. According to customer needs, the arrangement of the elastic layer 103 is designed to achieve an ideal elastic effect and satisfy the wrinkling effect by adopting a uniform distribution or a specific pattern arrangement. Similarly, the heat setting of the wrinkling process is formed by a cold and hot pressing double-temperature process, wherein the temperature during the hot pressing process is 140-150°C, the time is 20-25s, and the pressure is 3-3.5kg; during the cold pressing process, the temperature is 16-20°C, the time is 8-10s, and the pressure is 3.5kg. The shapes after wrinkling correspond to the adhesive area 1021 and the non-adhesive area 1022, respectively. Combined with the elasticity of the elastic layer 103, the wrinkles can still maintain good shape and elastic recovery performance under different stretching states.

[0041] Step 3: Connecting the elastic layer 2 to the structural layer 1.

[0042] According to the size and shape of the lower opening of the cuff hem, the elastic layer 2 is cut to a suitable length and width. Preferably, the stretch length of the fabric layer 101 is 1.2 to 1.5 times the maximum stretch length of the elastic layer 2, which is determined according to the required elasticity of the cuff hem. The larger the required elastic range of the cuff hem, the closer the stretch length of the fabric layer 101 is to 1 times the maximum stretch length of the elastic layer 2, and the maximum stretch length refers to the maximum length that can be elastically stretched.

[0043] The elastic layer 2 is wrapped on the structural layer 1 at the lower end of the cuff, that is, part of the elastic layer 2 is covered on the fabric layer 101, and part of it is covered on the elastic layer 103, and the length L of the elastic layer 2 wrapped on the surface of the structural layer 1 is 1 cm. By using a chain stitch machine, the elastic layer 2 is tightly fitted with the lower end of the cuff, ensuring that the elastic knitted belt is evenly and flatly covered at the lower end, thereby improving the quality and stability of the stitching. The stitching end face is 1.5 mm away from the end face of the elastic layer 2 wrapped on the structural layer 1. If the distance is too wide, it will affect the appearance. If the distance is too small, the firmness of the stitching will be poor and it will be easy to open the thread over time.

[0044] Step 4: Quality inspection and finished product finishing.

[0045] The finished structure is subjected to a comprehensive quality inspection. The inspection items include firmness, uniformity and stability of wrinkle effect, elasticity and stitching quality of the elastic layer 2, dimensional accuracy and appearance quality of the cuff hem, etc. Equipment such as tensile testing machine, microscope observation, and appearance inspection can be used to conduct strict inspections on various indicators. For unqualified products, timely analysis and processing should be carried out to find out the cause of the problem and take corresponding improvement measures.

[0046] Finally, the qualified products are sorted and packaged. Remove the thread ends and impurities on the cuffs and iron them to keep them smooth and beautiful. Then, according to the product specifications and packaging requirements, they are classified, packaged and labeled. The packaging materials should have moisture-proof, dust-proof and shock-proof functions to ensure that the products are not damaged during transportation and storage.

[0047] 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.

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.
