Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, specifically to an elastic seam structure for garment cuffs and hems. Background Technology

[0002] During daily wear and washing, the cuffs and hems of clothing are prone to friction with external objects. Without sewing, the yarn at the fabric edges can easily loosen and fall off, leading to edge damage and affecting the garment's appearance and lifespan. Sewing can wrap the fabric edges, enhancing their strength and reducing wear. For weft-stretch fabrics, the sewing structure for cuffs and hems typically involves folding the fabric edge towards the reverse side and then securing it with an overlock. This method creates two parallel stitches on the right side of the fabric. When the fabric stretches back along the weft direction, these stitches on the right side can easily arch and become snagged, causing the overlock stitches to break and fall off. Therefore, this application provides an elastic sewing structure for garment cuffs and hems. Utility Model Content

[0003] The purpose of this invention is to provide an elastic seam structure for garment cuffs and hems, which aims to increase the elasticity of the seam and prevent the seam from arching and cracking when the fabric is stretched and recovered along the weft direction.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: an elastic seam structure for clothing cuffs and hems, comprising: a fabric body, wherein the fabric body is a weft elastic fabric, the fabric body includes a connecting part, a bending part and a seam edge; an elastic band is provided on the side of the seam edge near the connecting part, the elastic band is fixed to the seam edge by overlocking; the seam edge is fixed to the connecting part by a triangular stitch method.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the stitch width of the triangular needle method is half the width of the elastic band.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the weft elastic fabric is woven from antibacterial warp yarns and elastic weft yarns.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial warp yarn is polylactic acid thymol antibacterial fiber filament.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial warp yarn is copper-modified antibacterial and anti-mite polyamide 6 fiber filament.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the elastic weft yarn is PTT fiber filament.

[0010] The beneficial effects of this utility model are as follows: Based on the elastic seam structure of this utility model for clothing cuffs and hems, the elastic band is attached to the seam, which can enhance the elasticity of the seam. The seam is fixed to the connecting part by the triangular stitch method. The stitches are interwoven to form a relatively tight structure, and can stretch and contract with the fabric. It will not cause the stitches to break or the seam to crack due to the stretching of the fabric, and can better adapt to the movement of the human body. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Combination Figure 1-4 This embodiment will be described in detail. An elastic seam structure for clothing cuffs and hems includes: a main fabric body, the main fabric body being a weft-elastic fabric, the main fabric body including a connecting part 1, a bending part 2, and a seam edge 3; an elastic band is provided on the side of the seam edge 3 near the connecting part 1, the elastic band being fixed to the seam edge 3 by overlocking; the seam edge 3 being fixed to the connecting part 1 by a triangular stitch method.

[0018] Furthermore, the stitch width of the triangular stitch is half the width of the elastic band.

[0019] The elastic band fits snugly against the seam edge 3, enhancing its elasticity. The triangular stitch stitches the seam edge 3 and the connecting part 1 together in a triangular pattern, creating a tightly interwoven structure. This structure can withstand a certain amount of tension and friction, preventing unraveling and ensuring the seam edge 3 at the cuffs and hem is secure, thus extending the garment's lifespan. The triangular stitches have a certain degree of elasticity, allowing the fabric to stretch and contract with the fabric when sewing cuffs and hems, preventing stitch breakage or seam edge 3 tearing due to fabric stretching. This better accommodates the movement of the human body.

[0020] Furthermore, the weft-elastic fabric is made of antibacterial warp yarns and elastic weft yarns interwoven together.

[0021] Furthermore, the antibacterial warp yarn is a polylactic acid-thymol antibacterial fiber filament. Polylactic acid-thymol antibacterial fiber is prepared by uniformly mixing polylactic acid, which has good biodegradability, with the natural antibacterial agent thymol using a temperature-controlled blending device, followed by melt spinning. Polylactic acid has excellent biodegradability; under natural conditions, it can be completely degraded into carbon dioxide and water, re-entering the ecosystem cycle. The substances produced during its degradation are also products of normal human metabolism and are harmless to the body. Thymol, also known as thymol, is extracted from plants of the genus Thymus and has excellent antibacterial and broad-spectrum antibacterial properties. It exhibits excellent antibacterial effects against Escherichia coli and Staphylococcus aureus. Antibacterial fibers prepared using polylactic acid as the base material and thymol as the antibacterial component not only possess excellent antibacterial effects and mechanical properties but are also biodegradable after use.

[0022] Furthermore, the elastic weft yarn is PTT fiber filament. PTT fiber is formed by melt polycondensation of 1,3-propylene glycol and dimethyl terephthalate after transesterification, or by melt polycondensation of 1,3-propylene glycol and terephthalic acid. PTT fiber has a smooth and rounded surface and is a semi-crystalline thermoplastic polyester. In the chemical structure of PTT fiber, there is a trans-para-para-trans conformation with the lowest energy, which presents a distinct "Z" shaped conformation. At the same time, there are three methylene units in the molecular chain link, so a strange carbon effect is generated between the molecular chains. This molecular structure gives PTT fiber the deformation ability like a coil spring and its resilience is better than PET and PBT.

[0023] Example 2

[0024] The difference from Example 1 is that the antibacterial warp yarn is copper-modified antibacterial and anti-mite polyamide 6 fiber filament. The copper-modified antibacterial and anti-mite polyamide 6 fiber filament is produced by coating nano-spherical copper antibacterial agents with oleic acid, then blending and extruding with a polyamide 6 matrix to obtain antibacterial and anti-mite PA6 chips, which are then melt-spun. After 50 washes, the copper-modified antibacterial and anti-mite polyamide 6 fiber exhibits an antibacterial rate of over 99% against Escherichia coli, Candida albicans, and Staphylococcus aureus. Its fabric achieves the highest level of mildew resistance (Level 0) and a mite repellency rate of up to 89%, demonstrating strong and durable antibacterial, mildew-proof, and anti-mite properties.

[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
