Background
The warm keeping is a very required function of winter cold protective clothing. For a long time, the warmth retention of cold wear mainly comes from the air layer locked by the special structure of the filler (filled cotton or down), but after all, the locked air layer is limited. CN87104396a discloses a cold protective garment comprising an inner lining, an outer fabric and a layer of foam (preferably about 1/4 inch thick) between which is located a plurality of open cells. The fabric is preferably woven from fine denier multifilament polyester or polyamide yarns. The surface of the foam layer against the liner may be a curled surface having peaks and valleys in a grid-like structure. The foam layer may have a surface layer on a flat large surface and a curled surface layer on the other surface, or may have surface layers on both surfaces; CN103082510a relates to a cold protective garment. The cold-proof garment consists of a garment face, a garment lining, bonding parts, an air charging device, an air discharging part and a zipper, wherein the garment face and the garment lining are sealed and airtight after being bonded around, the bonding parts are used for being bonded intermittently to control the air charging shape and air capacity, the air charging process is ensured by the air charging device, and the air charging device is arranged in a pocket of the cold-proof garment. The air charging device consists of an air suction valve, an air charging leather bag, an air inlet valve, an air inlet pipe, a connecting sleeve, an air inlet and a sticking piece, wherein the sticking piece is bonded with the periphery of the air inlet, and the air inlet is communicated with the air inlet. The air-filled bag has the advantages of portability, softness, rain and snow resistance and small folding volume, air is used as a filler, an air-filled device arranged in the bag is only needed to be pressed by hands, and the air used as a heat-insulating filler can enter from source, so that the heat-insulating layer is formed to play a role in cold protection. When not in use, the redundant air is discharged from the device, so that the device is convenient to fold, fold and release, brings convenience to people, and has poor heat reflection performance.
Because the cold protective clothing filler in the prior art has the problems of insufficient heat storage, heat reflection and the like, the development of the cold protective clothing filler with heat storage and heat reflection functions and the increase of the warm keeping and temperature locking functions are particularly necessary.
