Description

Technical Field

[0001] This utility model relates to the field of composite fabrics, specifically a down-proof knitted composite fabric. Background Technology

[0002] Currently, there are many types of composite fabric products. The aforementioned down-proof knitted composite fabric, based on the characteristics of down, solves the problem of down loss caused by yarn untwisting after normal daily washing when the down yarn is made into fabric. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a down-proof knitted composite fabric that addresses the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution:

[0005] A down-proof knitted composite fabric includes a surface mesh fabric and a bottom knitted fabric. The bottom knitted fabric includes an upper down-blend yarn surface and a lower ordinary yarn surface, and the down-blend yarn surface and the ordinary yarn surface are bonded together by connecting yarns. The surface mesh fabric is made of nylon fabric, and the surface mesh fabric and the bottom knitted fabric are bonded together by dot matrix hot melt adhesive dots.

[0006] Furthermore, the ordinary yarn in the ordinary yarn surface is polyester yarn.

[0007] Furthermore, the hot melt adhesive dots are distributed in a matrix, with a dot diameter of 0.3 mm and a center-to-center distance of 2 mm between adjacent dots.

[0008] Furthermore, the outer layer is plain weave mesh or other woven fabric, and the bottom layer is double-sided rib knitted fabric.

[0009] Furthermore, the surface layer is uniformly provided with a plurality of tapered through holes with a diameter gradient of 0.1-0.3 mm, and the hole spacing to hole diameter ratio is 3:1.

[0010] Furthermore, the hot melt adhesive dots are frustoconical in shape, with a base diameter of 0.3 mm and a top diameter of 0.1 mm.

[0011] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0012] This invention features excellent warmth retention and flexibility. The outer layer fabric is made of breathable nylon fabric, while the inner layer fabric is a composite fabric composed of down-blend yarn and ordinary yarn. After being combined with the outer layer fabric, the down-blend yarn is positioned between the outer layer fabric and the ordinary yarn, ensuring that the down will not fly out and guaranteeing that the fabric quality achieves the desired effect.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] A down-proof knitted composite fabric includes a surface mesh fabric 1 and a bottom knitted fabric 2. The bottom knitted fabric 2 includes an upper down-blend yarn surface 21 and a lower ordinary yarn surface 22, and the down-blend yarn surface 21 and the ordinary yarn surface 22 are bonded together by connecting yarns 23. The surface mesh fabric 1 is made of nylon fabric, and the surface mesh fabric 1 and the bottom knitted fabric 2 are bonded together by dot matrix hot melt adhesive dots 3.

[0021] In one embodiment, the ordinary yarn in the ordinary yarn surface 22 is polyester yarn.

[0022] In one embodiment, the hot melt adhesive dots 3 are distributed in a matrix, with a dot diameter of 0.3 mm and a center-to-center distance of 2 mm between adjacent adhesive dots.

[0023] In one embodiment, the outer layer is plain weave mesh or other woven fabric, and the bottom layer is double-sided rib knitted fabric.

[0024] In one embodiment, the surface layer is uniformly provided with a plurality of tapered through holes with a diameter gradient of 0.1-0.3 mm, and the hole spacing to hole diameter ratio is 3:1.

[0025] In one embodiment, the hot melt adhesive point 3 is truncated cone-shaped with a base diameter of 0.3 mm and a top diameter of 0.1 mm.

[0026] like Figure 1-2 As shown, this utility model uses a healthy fabric (air layer) structure. The bottom knitted fabric consists of an upper layer of down-blend yarn and a lower layer of ordinary yarn, which are bonded together to form a fluffy and dense bottom fabric with a finished weight of 175g / ㎡. The composite surface layer of nylon fabric has a weight of 150g / ㎡, and the total weight of the composite finished product is 320g / ㎡. This fabric is fluffy, lightweight, and has good warmth retention, making it suitable for clothing such as sweatshirts, long-sleeved T-shirts, jackets, and vests.

[0027] In practice, the outer layer fabric is made of nylon, but can also be composited with fabrics of varying thicknesses depending on whether it is worn as inner or outer clothing; both knitted and woven fabrics are acceptable. The ordinary yarn surface of the bottom layer fabric is made of high-F polyester yarn, using a double rib knitting method. This involves using three yarns to simultaneously weave the upper down-blend yarn surface, the lower ordinary yarn surface, and the connecting yarn in the middle, resulting in a bottom layer fabric that is a composite of down-blend yarn surface and ordinary yarn surface. The outer and bottom layers are then bonded together with dot-matrix hot melt adhesive to obtain a down-proof knitted composite fabric.

[0028] The needle arrangement and triangular arrangement of the upper down-blend yarn surface and the lower ordinary yarn surface in the bottom layer of the present invention are shown in Table 1:

[0029] Table 1

[0030]

[0031] In this context, “∧” and “V” represent loops, “n” and “U” represent tufted loops, and “-” represents a floating line.

[0032] Symbol definitions: ∧ / V → forming loops (forming the main structure), n / U → gathering loops (increasing fluffiness), - → floating lines (improving breathability). This triangular arrangement is just a representation; other similar arrangements are all within the protection.

[0033] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
