AI Technical Summary
The existing silk quilt fabric cannot meet consumers' requirements for differentiation and aesthetics of fabric surfaces. At the same time, traditional silk quilts need to add liner cloth in the middle of the quilt core fabric to prevent drilling of wire, which increases cost and complexity.
The anti-drill wire jacquard fabric adopts a double-layer structure. The double-layer area of the flower part is connected to the ground part through the single-layer area of the flower part. The shiny decorative weft yarn floats on the surface of the single-layer area of the flower part, forming a starlight effect, increasing the three-dimensionality and aesthetics of the cloth surface, and preventing the fiber from drilling out.
The fabric surface is differentiated and beautiful, which enhances the three-dimensionality and aesthetics of the pattern, and effectively prevents the silk flocs from drilling out, reducing production complexity and cost.

Description
Technical Field
[0001] The utility model belongs to the technical field of textile fabrics, and particularly relates to a large jacquard fabric with a starlight style and anti-fraying properties. Background Art
[0002] With the rapid development of social economy, people's living standards have been increasing day by day, and the quality requirements for all aspects of life are also getting higher and higher. The types of quilts to choose from have expanded from traditional cotton quilts to fiber quilts, silk quilts, and down quilts. And the requirements for the filling fabric of the quilt core have gradually shifted from comfort and durability to functionality and aesthetics. Traditional silk quilt fabrics are mainly two-dimensional plane fabrics such as all-cotton, viscose cotton, lyocell cotton, or lyocell viscose satin, small jacquard, or large jacquard, which cannot meet the requirements of consumers for fabric differentiation and aesthetics.
[0003] The prior art uses a multi-layer large jacquard structure to meet the requirements of fabric differentiation and aesthetics. For example, patent CN216998752U provides a large jacquard fabric with a micro-stereoscopic appearance. This fabric is formed by the interweaving of two groups of warp yarns and two groups of weft yarns, forming an upper and lower separated area and a connecting area. The upper and lower separated areas are distributed in a block shape on the fabric surface, and the connecting area is distributed in a linear shape on the fabric surface; in the upper and lower separated areas, the upper layer fabric is woven by the first warp yarn and part of the first weft yarn according to the five-harness three-fly warp satin weave or the five-harness two-fly warp satin weave, and the lower layer fabric is woven by the second warp yarn and the remaining first weft yarn according to the plain weave or the two-up-one-down twill weave. The second weft yarn is sandwiched between the upper layer fabric and the lower layer fabric and does not participate in the interweaving; in the connecting area, the first warp yarn sinks below the second warp yarn, and the second weft yarn sinks below the first weft yarn. This patent belongs to the technical field of thick woven large jacquard fabrics. Although it has a certain micro-stereoscopic effect and can meet the requirements of consumers for differentiation and aesthetics, in essence, it has three systems of weft yarns. Its first weft yarn is divided into two systems of upper layer weft yarn and lower layer weft yarn, and the second weft yarn exists as a filling yarn in the fabric, belonging to the third system. Moreover, the fineness of the filling yarn is generally relatively thick, resulting in an excessive overall fabric weight and a high product price, so the acceptance of consumers is not high.
[0004] In addition, a conventional lining fabric needs to be added between the mulberry silk floss and the fabric of the silk quilt core to prevent the long filaments of mulberry silk from drilling out of the fabric. However, this greatly increases the material cost, processing cost, and labor cost of the silk quilt shell. Summary of the Utility Model

[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] (1) The double-layered area of the floral part of the fabric is divided into an upper layer and a lower layer of the floral part, forming a layered cavity structure. The floral part is raised and has a certain thickness, and has a strong three-dimensional effect. The single-layered area of the floral part with a single structure is connected between the double-layered area of the floral part and the ground part.

The single-layer ground area is in a plaid pattern with good regularity, which can better highlight the flexible lines of the pattern. The double-layer ground area is in a plurality of blocks, and the blocks of the plurality of double-layer structures are connected by the single-layer plaid pattern, which can increase the stability of the structure. The decorative weft yarn is woven into the lower layer of the ground part and sunk under the warp yarn of the single-layer ground area, so that the decorative weft yarn is more prominent in the single-layer flower area.
[0019] (3) The single-layer jacquard fabric is interwoven with single warp and single weft, and the pores in the single-layer structure are straight. As the quilt core fabric, the flocculent fibers can easily drill out of the fabric surface through the pores. The utility model has a double-layer structure in both the ground part and the flower part. The pore channels in the double-layer structure are tortuous, which increases the difficulty for the flocculent fibers to pass through. For a silk quilt, it can effectively prevent the mulberry silk flocculents from drilling out of the fabric, so there is no need to add a lining cloth between the mulberry silk flocculents and the fabric, which can reduce the processing steps.
