Description

Technical Field

[0001] The utility model belongs to the technical field of clothing production, and particularly relates to a box-shaped three-dimensional down filling inner liner structure. Background Art

[0002] The box-shaped three-dimensional down filling inner liner structure forms multiple independent, box-like enclosed spaces between the inner and outer fabrics of the down jacket by adding multiple quilting lines, and these spaces are used to fill down to form a three-dimensional thermal insulation layer. Since the down in each enclosed space is independently separated, it helps the down to be evenly distributed inside the down jacket, preventing the down from shifting or aggregating during wearing, thereby maintaining the puffiness and thermal insulation performance of the down jacket. The box-shaped three-dimensional down filling inner liner structure is usually applied to high-end down jackets, outdoor down jackets, and down jacket products that require high thermal insulation performance.

[0003] The existing box-shaped down filling inner liner structure is as Figure 3 shown. Generally, the cut-through quilting process is adopted. This structure has advantages in terms of thermal insulation and design flexibility, but there are also some disadvantages. The cut-through quilting process directly connects the outer layer and the inner layer of the inner liner with a thread. Since there is no down at the stitched part, the outer fabric and the inner fabric are in direct contact, which easily forms cold spots, thus affecting the thermal insulation performance. At the same time, the sealing performance at the stitched part is not good, and the down filling is prone to flocking during washing, and the three-dimensional sense of the formed down filling box is not good, and the appearance quality and texture of the down jacket are not ideal enough.

[0004] Therefore, we provide a box-shaped three-dimensional down filling inner liner structure to solve the above problems. Summary of the Invention

[0005] The purpose of the utility model is to provide a box-shaped three-dimensional down filling inner liner structure for the problems in the background art.

[0006] The utility model realizes the above purpose through the following technical solutions:

[0007] A box-shaped three-dimensional down filling inner liner structure includes an outer fabric and an inner fabric. The outer fabric is stitched to the inner fabric, and multiple equidistantly distributed down filling chambers with a semi-elliptical cross-section are formed therebetween; U-shaped bending parts extending into the down filling chambers are folded on the outer fabrics on both sides of the down filling chambers.

[0008] As a further optimized scheme of the utility model, the U-shaped bending part includes a first folding line at the bottom of the U-shaped groove and a second folding line at the end of the U-shaped; a first stitching area for stitching the outer fabric to the inner fabric is provided at the first folding line, and a second stitching area for stitching the outer fabrics at the two ends of the U-shaped together is provided at the second folding line.

[0009] As a further optimized solution of the present utility model, a third stitching area for stitching the outer fabric to the inner fabric is provided between adjacent down filling chambers.

[0010] As a further optimized solution of the present utility model, the first stitching area, the second stitching area and the third stitching area are all stitched with threads.

[0011] As a further optimized solution of the present utility model, the distance between the first folding line and the second folding line is set to 2-3 cm.

[0012] As a further optimized solution of the present utility model, the outer fabrics of adjacent down filling chambers are in mutual abutment.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. By providing the first folding line, the second folding line, the first stitching area and the second stitching area, a U-shaped bending part extending into the down filling chamber can be formed on the outer fabric of the present utility model. The U-shaped bending part is stitched to the inner fabric by a new type of vertical lining quilting. Compared with the traditional cut-through quilting, the inner liner is filled with down more evenly and fluffily, avoiding thread traces pressing the down, significantly improving the warmth retention and comfort of the down jacket, and at the same time making the structural form of the down filling chamber more three-dimensional, capable of covering the stitches and enhancing the overall aesthetics and quality sense of the product.

[0015] 2. By providing the third stitching area, the stitching strength at the U-shaped bending part can be further enhanced, avoiding the down leaking due to the second stitching area coming unsewn, and at the same time improving the stability of the outer fabric on the inner fabric, avoiding the outer fabric and the inner fabric being in a separated state during human movement and affecting the wearing comfort.

[0021] The present application will be further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Embodiment 1

[0023] In order to solve the problem that the existing box-type down filling inner liner structure generally adopts the cut-through quilting process, directly connecting the outer layer and the inner layer of the inner liner with a thread. Since there is no down at the stitched part, the outer fabric and the inner fabric are in direct contact, which is likely to form cold spots, thus affecting the warmth retention performance, and the formed down filling boxes have poor three-dimensional sense. Please refer to Figure 1 , a box-type three-dimensional down filling inner liner structure provided by the present utility model includes an outer fabric 1 and an inner fabric 2. The outer fabric 1 is stitched to the inner fabric 2, and a plurality of equally spaced down filling chambers 3 with a semi-elliptical cross-section are formed therebetween. The outer fabrics 1 of adjacent down filling chambers 3 are in mutual contact; U-shaped bending parts extending into the down filling chamber 3 are folded on both sides of the down filling chamber 3 on the outer fabric 1. The U-shaped bending parts are stitched to the inner fabric 2 by a new type of vertical lining quilting. Compared with the traditional cut-through quilting, the down filling in the inner liner is more uniform and fluffy, avoiding thread marks pressing down the down, significantly improving the warmth retention and comfort of the down jacket. At the same time, the structural form of the down filling chamber 3 becomes more three-dimensional, which can block the stitches and improve the overall aesthetic appearance and quality sense of the product.

[0024] As Figure 2 shown, the U-shaped bending part includes a first folding line 101 at the bottom of the U-shaped groove and a second folding line 102 at the end of the U-shaped part. The distance between the first folding line 101 and the second folding line 102 is set to 2 - 3 cm; a first stitching area 103 for stitching the outer fabric 1 to the inner fabric 2 is provided at the first folding line 101, and a second stitching area 104 for stitching the outer fabrics 1 at the two ends of the U-shaped part together is provided at the second folding line 102.

[0025] When worn, the outer fabric 1 adheres to the human body. The vertical lining quilting design of the U-shaped bending part separates the inner fabric 2 from the human body by a large distance while separating the down, avoiding direct contact between the two and reducing the cold spots of the down jacket. In contrast, in the traditional cut-through quilting method, since there is no down at the stitched part, the inner fabric 2 is in direct contact with the human body, forming cold spots, thus affecting the warmth retention performance; and the setting of the U-shaped bending part also makes the stitches located inside the down filling chamber 3, achieving the effect of blocking the stitches and improving the overall aesthetic appearance of the product; and the setting of the U-shaped bending part also makes the structural form of the down filling chamber 3 more three-dimensional, thereby providing better three-dimensional form and structural support for the inner fabric 2, making the down jacket more straight and shaped, and improving the appearance quality and quality sense.

[0026] Embodiment 2

[0027] On the basis of Embodiment 1, in order to further enhance the sewing strength at the U-shaped bending part and prevent the fluff from escaping due to the unsewing of the second sewing area 104, as Figure 2 shown, a third sewing area 105 for sewing the outer fabric 1 to the inner fabric 2 is provided between adjacent filling chambers 3; the first sewing area 103, the second sewing area 104 and the third sewing area 105 are all sewn with sewing threads. The contact surface between the outer fabric 1 and the inner fabric 2 is stretched to a flat state during sewing.

[0028] The third sewing area 105 can further enhance the sewing strength at the U-shaped bending part, prevent the fluff from escaping due to the unsewing of the second sewing area 104, and at the same time improve the stability of the outer fabric 1 on the inner fabric 2, avoiding the separation of the outer fabric 1 and the inner fabric 2 during human movement and affecting the wearing comfort; and the U-shaped bending part can increase the thickness of the sewing part, equivalent to the thickness of two layers of the outer fabric 1, thereby enhancing the strength of the sewing part and improving the durability and service life of the inner liner.

[0029] The above embodiments only represent one implementation mode of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
