Description

Technical Field

[0001] This utility model relates to the field of slit technology, specifically to a slit strength structure. Background Technology

[0002] Clothing often features designs that hug the hips and waist to serve decorative, aesthetic, and ease-of-wear purposes, as well as allowing for freedom of movement at the cuffs. Current slit designs typically involve directly sewing the fabric below the seam facing backwards to form a slit edge, and then overlocking the seam above the slit. However, many fabrics, such as cotton, silk, and chiffon, have a loose weave. Currently, the seam allowance for small sleeve slits in the industry is only 0.3cm. The constant turning and folding during the slit construction makes the seam allowance prone to tearing and leaking, and the finished sleeve slit is also susceptible to breakage at stress points, affecting the product's appearance and damaging the brand's reputation.

[0003] An improved technique, such as the one described in application number 202320097726.6, involves a simple, sturdy, and flat shirt cuff. The cuff has an opening, one side of which is covered by a large cuff. The edge of the large cuff is sewn to one side of the opening to form a first seam. The other side of the opening is covered by a small cuff, the edge of which is sewn to the opening to form a second seam. The cuff is folded along a first fold line, so that the first large edge and the second large edge fit against the cuff. The first outer fold, the first inner fold, the inner end fold, and the outer end fold are folded inwards and sewn against the cuff. The cuff is then folded along a second fold line to fit the other side of the opening, so that the first small edge and the second small edge fit against the cuff. The second outer fold and the second inner fold are folded inwards and fitted against the cuff. The second seam is sewn along the edges of the second outer fold and the second inner fold, thus achieving a single, successful sewing without the need for repeated turning. However, its sturdiness still has some shortcomings. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a slit strength structure. This slit strength structure only requires adding arc-shaped reinforcing lines to the upper and lower slit edges, so that the force on the upper or lower slit edges is distributed, thereby improving the strength and reducing the possibility of breakage. Moreover, the process is simple and applicable to fabrics of various materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The slit structure has an upper slit edge and a lower slit edge, with the upper slit edge overlapping the lower slit edge. A top seam is provided at the top of the overlap, and an arc-shaped reinforcing line is sewn along the top seam towards the opening. The arc-shaped reinforcing line is sewn from the upper slit edge to the lower slit edge to increase the strength of the slit end.

[0007] Preferably, the upper slit edge is connected to an upper folded edge, which is folded inward to the back of the upper slit edge, and the two are stitched together to form an upper fold line.

[0008] Preferably, the lower slit edge is connected to a lower folded edge, which is folded inward to the back of the lower slit edge, and the two are stitched together to form a lower fold line.

[0009] Preferably, the upward fold line and the downward fold line are located at both ends of the top seam line, and there are gaps between the arc-shaped reinforcing line and the upward fold line and the downward fold line, with a gap width of 0.5-1cm.

[0010] Preferably, at least one layer of padding is provided between the lower slit edge and the lower fold edge, and both the lower fold line and the arc-shaped reinforcing line are sewn through the padding to increase the sewing strength of the arc-shaped reinforcing line.

[0011] Preferably, an adhesive liner is provided between the padding cloth and the folded edge to position and reinforce the padding cloth.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The slit strength structure of this utility model only requires adding arc-shaped reinforcing lines to the upper and lower slit edges, so that the force on the upper or lower slit edge is distributed, thereby improving the strength and reducing the possibility of breakage; and the process is simple and applicable to fabrics of various materials.
