Method of making a life jacket out of neoplan and deaplex material

摘要

The present invention relates to the development of a life jacket for thermal insulation that utilizes the properties of materials such as neoprene and diaflex and overcomes the limitations. Neoplan (outer surface); Diaflex (first lining) that prevents water absorption at a water pressure of 40000 mm or more and has a moisture-permeable function, so that the absorbed water can be discharged again; An air layer that places a fine air layer between the outer surface and the first lining to minimize heat dissipation, induce convection, and the water discharged from the first lining is evaporated from the air layer to maintain heat; It is characterized in that it comprises a; a seam to attach the surface and the surface by heat bonding, so that there is no leakage because it can be adhered without a sewing hole.
