AI Technical Summary
The stitching on the traditional curtain seams affects the aesthetics, and the lack of visible stitching on the seams results in a lack of sturdiness.
It adopts a concealed, unseen edge structure, which increases the strength by setting stitching lines on the folded edges of the surface and bottom layers, and using inner and outer adhesive layers and patterned threads to hide the stitching lines.
It achieves both aesthetic appeal and durability of the seamless edge, avoiding exposed sewing threads and improving the stability and stiffness of the edge.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of curtain accessories, particularly relates to invisible no clear line standing edge. BACKGROUND
[0002] The curtain is made of cloth, hemp, gauze, aluminum sheet, wood sheet, metal material and the like, and has the functions of sun-shading, heat-insulation and indoor light adjusting.
[0003] The standing edge is a part on the curtain located at the side edge, which is used to increase the crispness of the two side edges to increase the appearance. The traditional standing edge usually has a sewing machine thread, which will affect the appearance of the standing edge. The existing standing edge structure without clear line also has a great defect in firmness. SUMMARY
[0004] The utility model aims at providing the invisible no clear line standing edge which takes into account no clear line and firmness.
[0005] The above technical purpose of the utility model is realized by the following technical scheme: the invisible no clear line standing edge comprises a surface layer, upper folding edges are arranged inward on both sides of the surface layer, a side edge strip is arranged on the upper folding edge of one side, the side edge strip is sewn on the upper folding edge after being folded, and a thread is arranged in the folded part of the side edge strip; a bottom layer is sewn on the other side of the surface layer opposite the side edge strip, lower folding edges are arranged on both sides of the bottom layer, and the lower folding edge away from the side edge strip is sewn with the upper folding edge through a sewing thread; an inner adhesive layer is arranged in the lower folding edge on the side of the side edge strip, and an outer adhesive layer is arranged between the surface of the lower folding edge and the side edge strip.
[0006] Further, the lower folding edge on the side of the side edge strip is flush with the side edge strip.
[0007] Further, a plurality of pattern threads are sewn on the surface layer, and the pattern threads pass through the upper folding edge on the side of the side edge strip.
[0008] In summary, the utility model has the following beneficial effects: the thread on the traditional standing edge is hidden behind the thread to realize the no clear line structure, which has the advantages of high firmness and not easy to be pulled apart compared with the no clear line process on the market, and takes into account the conflict between firmness and no clear line. BRIEF DESCRIPTION OF DRAWINGS
[0009] Figure 1 It is a front view of the invisible no clear line standing edge;
[0010] Figure 2 It is a three-dimensional structure diagram of the invisible no clear line standing edge.
[0011] In the figure: 1, surface layer; 2, upper folding edge; 3, side edge strip; 4, bud line; 5, bottom layer; 6, lower folding edge; 7, inner adhesive layer; 8, outer adhesive layer; 9, pattern line. DETAILED DESCRIPTION
[0012] The utility model will be further explained in detail below in combination with the drawings.
[0013] The invisible no-clear edge includes a surface layer and a bottom layer.
[0014] The two sides of the surface layer are inwardly folded to set the upper folding edge. Figure 2 The upper folding edge and the lower folding edge at the right side position are fixed by sewing with sewing thread.
[0015] The upper folding edge at the left side position is sewn with a side edge strip by sewing thread. Figure 2 The side edge strip is folded and set with a bud line inside the folded part.
[0016] An inner adhesive layer is set between the inside of the lower folding edge at the left side. An outer adhesive layer is set between the surface of the lower folding edge at the left side and the side edge strip. The inner adhesive layer and the outer adhesive layer can increase the stiffness of the edge position. Figure 2 The left side is offset by 3mm hot pressing, so that the side edge strip can completely cover the sewing thread (clear line) of the surface layer and ensure the aesthetic degree of the edge.
[0017] After the inner adhesive layer is set, the outermost side of the side edge strip (i.e. the outermost side of the bud line) is flush with the outermost side of the lower folding edge at the left side.
[0018] A plurality of pattern lines are sewn on the surface layer. The pattern line can be in various forms. The pattern line is set to pass through the upper folding edge at the side where the side edge strip is located, so as to further ensure the stability of the upper folding edge of the surface layer. The pattern line can also be made of chenille gold silk velvet or leather rope material.
[0019] This embodiment is only an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to this embodiment without creative contribution after reading this specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
