Document Type and Number:
WIPO Patent Application WO/2022/099941
Kind Code:
A1
Abstract:
Provided is an air-fillable heat-retaining clothing fabric structure, comprising a first chemical-fiber fabric layer (100), a first polyurethane film layer (200), a second polyurethane film layer (300), and a second chemical-fiber fabric layer (400); one side of the first chemical-fiber fabric layer (100) is glued to one side of the first polyurethane film layer (200); the surrounding edge of the other side of the first polyurethane film layer (200) is glued to one side of the second polyurethane film layer (300); a gap is left between the first polyurethane film layer (200) and the second polyurethane film layer (300); during the process of wearing and using the invention, air can be filled between the two polyurethane film layers (200, 300) by means of an air inlet valve (500), and the air is confined between the two polyurethane membranes (200, 300); thus the invention has the function of heat retention and also, in an emergency situation, provides buoyancy to a user when drowning so as to perform a life-saving role, while the air inlet valve (500) and the air outlet valve (600) are also provided so as to enable free adjustment of the filled air, ensuring that the air is collected and released freely.
