を着用している。2. Description of the Related Art Workers on board a fishing boat, icebreaker, or other workboat operating in the sea or lake in cold regions are required to prepare for extremely cold accidents in case of a waterfall accident or a capsizing accident. They wear insulated and life-saving garments and workwear for cold weather so that they do not freeze immediately after falling into the water.

しまうものであった。[0003] However, in the case of such life-saving garments and winter clothing, a buoyant body such as cotton or styrofoam is packed between multi-layered cloths in order to maintain a sufficient heat retaining property, being lighter than water. The surface was film-laminated or coated with a rubber-like material so that water did not penetrate into the garment, and the structure was such that the air permeability of the garment was sacrificed. For this reason, when such wear is worn, it immediately sweats and gets stuffy.

4989号等が提案されている。[0004] Further, in other life vests and work clothes for cold weather, for example, in the form of a waistcoat, a fixed or inflatable life-saving buoyant body is made of foam in order to prepare for an accident under water. On the other hand, in the inflatable type, a buoyancy is obtained by inflating a life-saving airbag instantaneously with carbon dioxide gas or the like by using plastic or cork. Such a life vest is disclosed, for example, in JP-A-59-1000.
No. 85, JP-A-60-116587, JP-A-4-27
No. 4989 has been proposed.

い状況にあり、防水性、断熱性、保温性、軽量性、柔軟

すべて満足するものではなかった。[0005] However, this work wear for life vests or for cold weather swells the buoyant body and the airbag portion and lacks air permeability and flexibility. In order to ensure waterproofness and heat insulation, it is unavoidable to sacrifice "humidity" and "movability", and it is difficult to say that comfort and workability are good. However, they did not satisfy all of the conditions of heat insulation, heat retention, light weight, flexibility, stuffiness, and sufficient buoyancy.

い、前述の問題を解決に至るものはなかった。[0006] For example, if the workwear for life vests and winter clothing is made of a breathable cloth in order to release moisture and prevent stuffiness, it absorbs water from the cloth at the time of falling water to provide buoyancy and heat insulation. Insulation and buoyancy are reduced, and if the life vest is thinned to make it easier for heat to escape, the heat insulation and buoyancy are reduced, and the safety is lacking, leading to the solution of the above-mentioned problem. There was nothing.

り、作業安全性の点が問題視されている。In such a conventional life-saving garment or cold weather workwear, when worn, heat from the body is less likely to be released, sweating and sweating, impairing wearing comfort, and saving life. Because the buoyancy body expands and the workability is impaired, the worker may take off the wear while knowing that it is dangerous,
The work may be performed with the chuck opened, and work safety is regarded as a problem.

救命着兼用防寒用作業ウェアを切望していた。For this reason, the worker has a breathability even in ordinary work and can work without getting stuffy, and also has cold protection and buoyancy even in the event of falling into extremely cold water, thus ensuring safety. It has been a longing for a workwear for life protection and cold protection.

In addition, a waterproof breathable film that does not allow liquids such as water to pass therethrough but allows moisture and air to pass through has been developed, and is used as a material for breathable wear and the like in sportswear and the like. However, as a material having functions such as buoyancy and air permeability, a material focusing on these combinations has not yet been developed.

First, a description will be given of the buoyancy body 20 having a space having air permeability used in the work wear 1 for lifesaving / cold protection work. When the buoyant body 20 is sealed with the waterproof breathable film 31 as the interior body 30, a space through which the breathable body 20 can be ventilated is secured, and the flexibility of the waterproof breathable film 31 is not impaired. A material having a lower bulk specific gravity can be used. For example, a sponge having open cells, a granular styrofoam, a lightweight filler, a coarse cloth, or the like can be used.

入した場合には全体の浮力が無くなくこともない。Among them, it is particularly preferable to use a fiber (hollow fiber) 22 or a filler (hollow filler) 21 having a hollow structure inside in terms of lightness, heat retention, heat insulation, and buoyancy. These hollow fibers 22 and hollow fillers 21 are hollow inside and have air therein, so that their bulk specific gravity is light,
Extremely large buoyancy can be obtained by sealing the air. And, for example, if a fiber or filler that seals the air is used, even if one part is torn, and even if air leaks from that part, the air in the other part is retained, so these are used as buoyant bodies. When the water is used, the heat retention of the whole buoyancy body is not impaired, and when water invades at the time of falling, the whole buoyancy is not lost.

I can give it. When the hollow fibers 22 are used, the fibers need to be bundled or knitted to form a cloth, and at least the outer peripheral area needs to be heat-welded, since both ends of the fibers are welded and the air inside is sealed. In addition, the heat insulation and buoyancy of the fiber can be improved.
In addition, when the partition streaks are formed by partially adhering not only in the outer peripheral area of the cloth but also on the inner side thereof, the internal space of the fiber is divided, and even if the buoyancy and the heat insulating property are slightly reduced, the fiber is partially removed. The air leakage when the rupture is broken can be reduced, and a decrease in buoyancy of the entire buoyant body can be suppressed. In sealing the air inside the hollow fiber 22, when the buoyant body 20 is sealed in the interior body 30 by heat welding, the fiber can be sealed simultaneously with the welding, so that the air of the fiber is sealed in advance. You don't have to. In the case where the buoyant body 10 is bonded by an adhesive, a woven fabric is formed by first heat-welding the two ends of the hollow fiber and then the outer peripheral region is heat-sealed after the hollow fiber is woven. Shall be stopped.
