Technical Field
[0001] This utility model relates to the field of down jacket technology, specifically a warm, two-piece down jacket. Background Technology
[0002] Down jackets are a type of clothing used to keep warm. In cold weather, most people choose to wear down jackets to stay warm.
[0003] Existing down jackets divide the down filling space into several compartments by stitching threads through both the outer and inner layers, allowing the down to fill the entire jacket evenly and thus achieving a good warmth retention effect. However, with prolonged wear, down feathers can easily escape from the stitching holes, causing down leakage. This reduces the jacket's warmth retention and causes inconvenience to the wearer.
[0004] Therefore, a warm, two-piece down jacket is needed to solve this problem. Utility Model Content
[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a warm, two-piece down jacket.

The outer layer is evenly provided with a plurality of sewing threads, which divide the outer layer into a plurality of down-storing spaces. Each of the plurality of down-storing spaces is provided with an inner lining strip, which is filled with down. The two ends of the inner lining strip are sealed by ultrasonic welding at the sewing thread positions on both sides.
[0007] The present invention is further configured such that: the inner liner strip consists of a first insulation layer and a second down-proof layer, the first insulation layer is woven from insulation yarn in a double rib weave, the second down-proof layer is spunlace nonwoven fabric, and the first insulation layer and the second down-proof layer are connected by ultrasonic welding technology.
[0008] The present invention is further configured such that the double rib knit is a two-way loop, the first way being plain rib triangle, loop triangle, loop triangle, plain rib triangle; the second way being loop triangle, plain rib triangle, plain rib triangle, loop triangle.
[0009] The present invention is further configured such that the pore size of the spunlace nonwoven fabric is smaller than the diameter of the fibers.
[0010] The present invention is further configured such that: the heat-insulating yarn includes a core yarn and a winding yarn, the winding yarn is spirally wound around the outside of the core yarn, the winding yarn is made of multiple strands of polyester fiber twisted together, and the core yarn is made of multiple strands of cotton fiber twisted together.
[0011] The present invention is further configured such that the polyester fiber is an irregularly shaped fiber with a Y-shaped cross-section.
[0012] In summary, this utility model has the following beneficial effects: it allows the fleece to be evenly distributed and well fixed in the corresponding positions, preventing the fleece from falling out of the sewing thread, thereby maximizing the good warmth retention performance of the fleece itself, effectively blocking the entry of cold air from the outside, and creating a warm feeling for the wearer.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", 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 the present 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 the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] A type of warm, two-piece down jacket, such as Figure 1 , Figure 2 As shown, it includes an outer layer 1 with a zipper 3 and a fake inner layer 2 sewn to the outer layer 1. The outer layer 1 is evenly provided with a number of sewing threads 4, which divide the outer layer 1 into a number of down storage spaces 5. Each of the down storage spaces 5 is provided with an inner strip 6, which is filled with down 7. The two ends of the inner strip 6 are sealed by ultrasonic welding at the positions of the sewing threads 4 on both sides.
[0020] Practical effect: The fleece 7 is evenly distributed and well fixed in the corresponding position, preventing the fleece 7 from falling out of the sewing thread 4, thereby maximizing the good warmth retention performance of the fleece 7 itself, effectively blocking the entry of cold air from the outside, and creating a warm feeling for the wearer.
[0021] like Figure 2 As shown, the inner liner 6 consists of a first insulation layer 61 and a second down-proof layer 62. The first insulation layer 61 is woven from insulation yarn 8 in a double rib weave. The second down-proof layer 62 is spunlace nonwoven fabric. The first insulation layer 61 and the second down-proof layer 62 are connected by ultrasonic welding technology. In this embodiment, the pore size of the spunlace nonwoven fabric is smaller than the diameter of the down 7.
[0022] Double rib weave has unique structural features. It has good elasticity and the yarns are relatively tightly interwoven, which can retain more still air and ensure the insulation effect of the insulation layer. The non-woven fabric with a pore size smaller than the diameter of the pile 7 prevents the pile 7 from escaping out of the insulation layer.
[0023] like Figure 3 As shown, the double rib structure is a two-way loop. The first way is a plain rib triangle, a loop triangle, a loop triangle, and a plain rib triangle; the second way is a loop triangle, a plain rib triangle, a plain rib triangle, and a loop triangle. This method can increase the thickness of the first insulation layer 61 and increase its heat preservation performance.
[0024] like Figure 4 As shown, the insulating yarn 8 includes a core yarn 9 and a winding yarn 10. The winding yarn 10 is spirally wound around the outside of the core yarn 9. The winding yarn 10 is made of multiple strands of polyester fiber 11 twisted together. The core yarn 9 is made of multiple strands of cotton fiber 12 twisted together. Specifically, the polyester fiber 11 is a Y-shaped irregular fiber. The Y-shaped cross-section of the polyester fiber 11 creates multiple gaps on the surface of the polyester fiber 11, through which gas can be conducted, thereby improving the breathability of the down jacket. The core yarn 9 is made of multiple strands of cotton fiber 12 twisted together. The cotton fiber 12 has a warming effect, which further increases the warmth of the down jacket.
