Description

Technical Field

[0001] This invention relates to the field of clothing technology, specifically to a seamless thermo-bonded denim jeans structure. Background Technology

[0002] Denim clothing has long dominated the mainstream market for everyday wear due to its classic design and durable fabric. In traditional denim manufacturing, the front, back, waistband, and pocket pieces are connected and fixed by sewing with needle and thread. This structure, which relies entirely on sewing, has many defects.

[0003] From a wearing experience perspective, the stitched construction of jeans results in raised seams at the fabric seams, which not only reduces the simplicity of the garment's appearance but also makes it prone to rubbing against the skin during exercise. At the same time, the stitched structure restricts the stretching and movement of the fabric, causing the wearer to feel noticeably restricted during light activities such as jogging and cycling, with limited joint mobility. Furthermore, the conventional processing methods of traditional denim fabric also result in insufficient breathability, making it unsuitable for the wearing needs of light exercise scenarios.

[0004] In terms of product categories, existing technologies often use TPU and other sports adhesive strips in the joints and waist areas of professional sportswear. These strips effectively enhance fabric elasticity, provide muscle support, and improve the wearing experience during exercise. However, there is currently no technical solution that effectively combines sports adhesive strips with denim fabrics. Traditional denim clothing retains the distinctive style of denim but lacks athletic functionality. While professional sportswear possesses characteristics such as high elasticity, breathability, and support, its sporty style has caused it to lose the classic fashion sense of denim fabric, failing to meet users' needs for efficient dressing after daily commutes so they can directly participate in light exercise without changing clothes. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the above and / or existing seamless hot-pressed adhesive structures of jeans, the present invention is proposed.

[0007] This invention provides a seamless hot-pressed adhesive structure for jeans, including a jeans body and several sports adhesive strips. The jeans body is made of denim fabric, and the sports adhesive strips are hot-pressed and bonded to the jeans body through a high-temperature hot-pressing process. This eliminates the need for traditional needle and thread stitching, structurally solving the friction and restriction problems caused by sewing threads.

[0008] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A seamless hot-pressed bonded structure for jeans includes a jeans body and several sports adhesive strips. The jeans body is made of denim fabric, and the sports adhesive strips are hot-pressed to the jeans body through a high-temperature hot-pressing process. The front pocket, front pocket opening, back pocket opening, and leg opening of the jeans body are all fitted with single-sided motion adhesive strips. The inner seam, outer seam, front wave, back wave, back hem, and back pocket seam of the jeans body are all provided with motion adhesive strips along the seam direction.

[0009] As a preferred embodiment of the seamless hot-pressed adhesive structure of jeans described in this invention, the material of the sports adhesive strip is TPU, and the width of both the single-sided sports adhesive strip and the sports adhesive strip set along the seam direction is 1-2cm.

[0010] As a preferred embodiment of the seamless hot-pressed adhesive structure of jeans described in this invention, the parameters of the high-temperature hot-pressing process are: hot-pressing temperature 120-140℃, hot-pressing pressure 0.3MPa, and hot-pressing time 2.5-5.5s.

[0011] As a preferred embodiment of the seamless hot-pressed adhesive structure of jeans described in this invention, the outer thigh of the jeans body is further provided with segmented sports adhesive strips, which are 3-4 short adhesive strips, each of which is 5-8cm long and the distance between two adjacent short adhesive strips is 2-3cm.

[0012] As a preferred embodiment of the seamless hot-pressed bonding structure of jeans described in this invention, the denim fabric is any weight denim fabric that can be faded or non-faded, and the denim fabric is treated with a light fermentation washing process or a light fermentation washing process combined with other industrial washing processes.

[0013] As a preferred embodiment of the seamless hot-pressed adhesive structure of jeans described in this invention, after the denim fabric has been washed 50 times, the fabric breaking strength retention rate is not less than 85%, and the adhesion retention rate between the sports tape and the denim fabric is not less than 90%.

[0014] In a preferred embodiment of the seamless hot-pressed adhesive structure of jeans described in this invention, the sports adhesive strip is a low-saturation color adhesive strip in the same color family as the jeans body.

[0015] As a preferred embodiment of the seamless hot-pressed adhesive structure of jeans described in this invention, the motion adhesive strips provided at the inner seam, outer seam, front wave, back wave, back hem, and back pocket seam of the jeans body are double-sided motion adhesive strips, and the adhesive surface of the double-sided motion adhesive strips is hot-pressed and bonded to the jeans body.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention combines the elasticity, support, and breathability of sports tape with the classic fashion and wear-resistant properties of denim fabric, giving the product both a fashionable feel for daily commuting and the functionality of light sportswear, thus reducing the cost of dressing decisions for users.

[0017] The high-temperature hot-pressing process achieves seamless bonding between the sports tape and the denim fabric, eliminating the traditional needle and thread stitching structure. This results in a smooth and flat surface for the jeans, avoiding the problem of seams rubbing against the skin and improving the comfort of daily wear. It also eliminates the restriction of fabric stretching by seams, allowing for greater freedom of joint movement. At the same time, the breathable microporous structure of the sports tape solves the problem of insufficient breathability in traditional denim fabrics.

[0018] Using low-saturation color sports tape in the same color family as the jeans creates a visual fusion between the functional tape and the denim fabric. This retains the classic recognizability of denim while differentiating it from traditional non-functional jeans and styleless professional sportswear. The use of invisible functional symbols enhances the product's design and creates a unique competitive advantage. At the same time, the seamless bonding structure makes the jeans look simpler and more sophisticated, enriching the design style of denim clothing.

[0019] By optimizing the parameters of the high-temperature hot-pressing process, the sports tape is ensured to bond tightly to the denim fabric. Combined with denim fabric treated with processes such as light fermentation washing, the sports tape does not fall off or curl after 50 washes. The fabric's tensile strength and tape adhesion still maintain a high retention rate, effectively improving the product's service life and meeting the high-frequency use needs of everyday clothing.
