Problems solved by technology

However, since the stitches destroy the texture, density or processing resin layer of the fabric during sewing or quilting, it will reduce the fleece resistance, wind resistance and water resistance of the fabric
[0003] In order to solve the above problems, someone proposes to use tissue design to form a cavity area in the fabric. For example, the patent CN204483166U discloses a kind of anti-drilling fleece fabric, which is obtained by exchanging the inner and outer layers of fabrics to form interval lines. No sewing is required, but the exchange The place cannot be completely filled with down, and the thickness is different, which affects the overall warmth effect
[0004] Another example is the patent CN201785576U which discloses a three-dimensional fabric and a three-dimensional fabric filling body using the fabric. By setting the connecting layer between the top layer and the bottom layer, the upper and lower sides are interlaced with the top layer and the bottom layer respectively. A fan-shaped cross-section cavity is formed between positive and negative connections. This structure solves the problem of not keeping warm at the connection part and the overall thickness is different. However, because the surface warp yarn, the middle layer warp yarn and the inner layer warp yarn are independent weaving systems, the tension of the warp yarn is not easy. Control, weaving is difficult; and after dyeing, the surface of the fabric is prone to problems such as poor flatness

Embodiment 1

[0032] On the single-shaft dobby loom, 55dtex-144f-polyester DTY is used as the warp and weft yarn, and 12 heald frames are used for weaving. The surface layer, middle layer and inner layer are all plain weave, and the three layers are connected by mutual exchange; The width of the bag-shaped area is 10cm, the middle layer is a single layer, and the warp and weft density of the surface layer, middle layer and inner layer are all 166*140 threads / inch, and the three-dimensional fabric gray cloth is obtained, and then undergoes scouring (temperature 95°C) → intermediate shaping ( 180°C)→disperse dyeing (135°C*30min)→drying (150°C)→resin processing (water-repellent agent 30g / l)→finishing and other processing to obtain the finished product.

[0033] The obtained three-dimensional fabric has smooth surface and soft hand feeling. According to the GB Downproof Test, the three-dimensional fabric has 8 pieces of velvet, and the amount of velvet filling is 200g / m 2 When the thermal insu...

Embodiment 2

[0035] On the single-shaft dobby loom, 55dtex-144f-polyester DTY is used as the warp and weft yarn, and 10 heddle frames are used for weaving. The surface layer, middle layer and inner layer are all plain weave, and the three layers are connected by mutual exchange; The width of the bag-shaped area is 6cm, the warp and weft density of the surface layer and the inner layer are 166*140 threads / inch, the middle layer is a single layer and the warp and weft density is 83*70 threads / inch, and the three-dimensional fabric gray cloth is obtained, and then includes scouring ( Temperature 95°C)→intermediate setting (180°C)→disperse dyeing (135°C*30min)→drying (150°C)→resin processing (water-repellent agent 30g / l)→finished product setting and other processing to obtain the finished product.

Embodiment 3

[0038] On the single-shaft dobby loom, 44dtex-68f-nylon DTY is used as the warp and weft yarn, and 22 heald frames are used for weaving. The surface layer, middle layer and inner layer are all plain weave, and the three layers are connected by mutual exchange; The width of the bag-shaped area is 8cm, the warp and weft density of the surface layer and the inner layer are 176*140 threads / inch, the middle layer is a single layer and the warp and weft density is 35*28 threads / inch, and the three-dimensional fabric gray cloth is obtained, and then includes scouring ( Temperature 95°C)→intermediate setting (180°C)→acid dye dyeing (90°C*20min)→drying (150°C)→resin processing (water repellent agent 30g / l)→finished product setting and other processing to obtain the finished product.

[0039] The obtained three-dimensional fabric is soft to the touch; the density of the middle layer is on the low side, and the effect of separating fillers tends to be weakened, and the surface smoothness ...

Abstract

The invention discloses a stereoscopic fabric. The stereoscopic fabric is prepared through interweaving warp and weft, and comprises a surface layer, an intermediate layer and an inner layer, wherein each warp yarn is simultaneously used as the warp yarn of the surface layer, the intermediate layer and the inner layer, forms a loop through passing through the surface layer, the intermediate layer and the inner layer sequentially, and is interwoven with the weft yarn of the surface layer, the weft yarn of the intermediate layer and the weft yarn of the inner layer so as to form an independent surface layer fabric, an independent intermediate layer fabric and an independent inner layer fabric. The stereoscopic fabric has the advantages of being simple and convenient in production process and low in cost, and cloth filled with the stereoscopic fabric has the advantages of being uniform in thickness, flat in surface and excellent in thermal insulation performance.

Description

technical field [0001] The invention relates to a three-dimensional fabric, in particular to a multi-layer structure fabric with simple production process, excellent heat retention, difficult leakage of fillers, and direct filling without sewing. It is especially suitable for making warm clothes, down jackets and the like. Background technique [0002] At present, most of the down jacket fabrics on the market are made by sewing single-layer fabrics with sewing equipment or quilting equipment. However, since the seam destroys the fabric structure, compactness or processing resin layer during sewing or quilting, it will reduce the fleece resistance, wind resistance and water resistance of the fabric. [0003] In order to solve the above problems, someone proposes to use tissue design to form a cavity area in the fabric. For example, the patent CN204483166U discloses a kind of anti-drilling fleece fabric, which is obtained by exchanging the inner and outer layers of fabrics to ...
