Problems solved by technology

[0002] Single-layer fabrics are relatively lacking in functionality, fullness, and styling. For this reason, some people propose to use sewing equipment or quilting equipment to sew multiple layers of fabrics together to form a three-dimensional structure, but this sewing process is more complicated. The needle will destroy the tissue structure of the fabric, reduce the fleece resistance and windproof performance of the fabric, etc.
In order to solve the above-mentioned problems, someone has proposed the technology of the seamless weaving mode with strong joints, as disclosed in the Chinese patent document CN204483166U, a kind of anti-drilling fleece fabric is obtained by exchanging the inner and outer layers of fabrics to form interval lines, but Such a structure causes the exchange point to not be completely filled with down, and the thickness varies, which affects the overall warmth retention effect.
[0003] As another example, the Chinese patent document CN205115746U discloses a three-dimensional fabric, which forms interlaced three-dimensional cavities through the interlaced connection of the middle layer with the outer layer and the inner layer respectively. The problem, but because the three-dimensional fabric has no stretchability, the wearing comfort is not good
[0004] For another example, the Chinese patent document CN107083603A discloses a three-dimensional fabric with a relatively low density in the middle layer. The surface layer, the middle layer and the inner layer are respectively interwoven with special-shaped fiber yarn and elastic yarn to obtain an elastic three-dimensional fabric. However, in such a density design Under certain conditions, the elastic yarns in the three layers of the surface have poor shrinkage, so the surface of the fabric will be uneven.

Embodiment 1

[0040] On the double-shaft dobby loom, 30D-72f-polyester DTY (manufactured by Jiangsu Hengli Chemical Fiber Co., Ltd.) is selected as the surface warp, middle warp, inner warp and middle weft, and 20D PU (Jiangsu Kelong Spandex Co., Ltd.) / 20D-72f-polyester DTY (manufactured by Jiangsu Hengli Chemical Fiber Co., Ltd.) The 27D polyester-spandex covered yarn is used as the surface weft yarn and the inner weft yarn. The warp and weft density of the surface layer and the inner layer is 210*228 / Inch, the warp and weft density of the middle layer is 105*114 threads / inch, weaving under the condition of plain weave to obtain a three-layer woven gray fabric, and then the resulting gray fabric is scouring (95°C)→intermediate setting (180°C)→dispersion Dye dyeing (135°C*30min)→drying (150°C)→resin processing (fluorine-free water repellent KG-70N, manufactured by Zhuhai Huada Haohong Chemical Co., Ltd., 30g / l)→setting processing to obtain the available Filled with elastic fabric, the par...

Embodiment 2

[0042] On the single-shaft dobby loom, each warp yarn is interwoven with the surface layer weft yarn, the middle layer weft yarn, the inner layer weft yarn and the middle layer weft yarn in the order of surface, middle, inner, and middle, and the rest are the same as in Example 1 to obtain the present invention. The filling elastic fabric, the parameters are shown in Table 1.

Embodiment 3

[0044] On a single-shaft dobby loom, the warp and weft density of the middle layer is 70*76 threads / inch, and the rest is the same as in Example 2 to obtain the filling elastic fabric of the present invention. The parameters are shown in Table 1.

Abstract

The invention discloses an elastic fabric of a filling structure. The fabric comprises a surface layer, middle layers and a lining layer, wherein the surface layer is formed by intertwining warp and weft. The middle layers are connected with the surface layer and the lining layer correspondingly to form multiple bag-shaped areas which can be filled. The density of the surface layer and the densityof the lining layer are each greater than that of each middle layer. The surface layer and the lining layer each internally contain elastic yarn. The middle layers are formed by non-elastic yarn. Thesurface roughness of the elastic fabric ranges from 5 microns to 30 microns. The elastic filling fabric is even in surface and excellent in elasticity; after filling, a fabric surface is uniform in thickness and even, and the warmth retention performance is excellent.

Description

technical field [0001] The invention relates to a one-time molding elastic fabric with a filling structure, which can be used to make clothes, quilts, cushions, sleeping bags, toys and the like. Background technique [0002] Single-layer fabrics are relatively lacking in functionality, fullness, and styling. For this reason, some people propose to use sewing equipment or quilting equipment to sew multiple layers of fabrics together to form a three-dimensional structure, but this sewing process is more complicated. The needle will destroy the tissue structure of the fabric and reduce the downproof and windproof properties of the fabric. In order to solve the above-mentioned problems, someone has proposed the technology of the seamless weaving mode with strong joints, as disclosed in the Chinese patent document CN204483166U, a kind of anti-drilling fleece fabric is obtained by exchanging the inner and outer layers of fabrics to form interval lines, but Such a structure causes...
