Description

Technical Field

[0001] The utility model relates to the technical field of down blankets, in particular to a down blanket and a down sleeping bag using seamless, integrated weaving and double-sided down-locking technology. Background Art

[0002] A down blanket is a lightweight and warm blanket that provides excellent warmth. It's filled with down, which creates an air layer to maintain body temperature.

[0003] In the existing technology, a large number of stitches are generated during the sewing process of anti-down fabrics. The quilting is simple and has few changes, which is not beautiful. Not only does it affect the appearance, but it also easily becomes a channel for down to drill out. In many cases, the anti-down drilling test is performed by drilling down from a pinhole, which is particularly likely to cause physical discomfort to people with rhinitis or allergies. Therefore, there is an urgent need to design a down blanket and down sleeping bag with seamless one-piece woven double-sided down locking technology to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a down blanket and a down sleeping bag with seamless one-piece woven double-sided down-locking technology, so as to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A down blanket with seamless one-piece woven double-sided down locking technology comprises an outer high-density anti-down layer and an inner high-density anti-down layer, a plurality of seamless one-piece woven down locking channel interwoven threads are arranged between the outer high-density anti-down layer and the inner high-density anti-down layer, a plurality of filling cavities are formed between the outer high-density anti-down layer, the inner high-density anti-down layer and the seamless one-piece woven down locking channel interwoven threads, the interior of the filling cavities is filled with fluffy down, and a plurality of inner seam back curling edges are arranged between the outer high-density anti-down layer and the inner high-density anti-down layer.

[0007] Furthermore, the edges of the outer high-density anti-down layer and the inner high-density anti-down layer are provided with edge curling, and the width of the edge curling is 1 cm.

[0008] Furthermore, the specifications of the seamless one-piece woven lock velvet channel interwoven threads are respectively 88% nylon + 12% spandex microfiber yarn and 100% polyester fiber ultra-thin double-layer cloth yarn, and the spacing between several of the seamless one-piece woven lock velvet channel interwoven threads is 5.5 cm.

[0009] Furthermore, the length and width of the outer high-density anti-down layer and the inner high-density anti-down layer are the same, and the length and width of the outer high-density anti-down layer and the inner high-density anti-down layer are 142 cm and 90 cm respectively.

[0010] Furthermore, a double-layered bag is sewn on the other side of the inner high-density anti-down layer away from the outer high-density anti-down layer, and the length and width of the double-layered bag are 8 cm and 1.5 cm respectively.

[0011] A seamless, one-piece woven double-sided down-locking technology down sleeping bag also includes a female snap button, several male snap buttons and an invisible zipper arranged on an outer high-density anti-down layer. The spacing between the several male snap buttons is 7.5 cm, and the distance between the female snap button and the top edge of the outer high-density anti-down layer is 2.5 cm.

[0012] Furthermore, the number of the invisible zippers is two, and the two invisible zippers are symmetrical to each other about the transverse center line of the outer high-density anti-velvet layer.

[0013] In the above technical solution, the utility model provides a down blanket and down sleeping bag with seamless one-piece woven double-sided down-locking technology.

[0014] (1) The seamless one-piece woven lock-down channel interwoven thread is light in weight, making the down blanket produced by seamless one-piece woven double-sided lock-down technology lighter and almost without stitching lines, which can prevent the down from drilling out from the needle holes of the stitching lines. It also solves the problem of the prior art that coatings and anti-linings are needed to prevent the down from drilling out, which affects the air permeability and softness of the fabric, making the down blanket more breathable and skin-friendly, and more environmentally friendly. The track filling technology can combine the outer high-density anti-down layer and the inner high-density anti-down layer into one to form several filling cavities, so that the fluffy down is reasonably distributed inside the filling cavities of the outer high-density anti-down layer and the inner high-density anti-down layer, forming a lightweight and high-air-content "microclimate" protective layer that is breathable and moisture-wicking;

[0015] (2) By setting the female snap button, male snap button and invisible zipper, when the invisible zipper is opened, the arm can be extended from the opening, and the down blanket can be put on the body and wrapped around the body. By fastening the female snap button and male snap button, it can be turned into a down sleeping bag. When you are lost in the wild or encounter extreme weather and cannot return to the camp or residence in time, you can wrap it around your body to preserve body heat to the maximum extent.
