Abstract
Description
本発明は、保温性を有する透湿性防水布帛に関するものである。 The present invention relates to a moisture-permeable waterproof fabric having heat retention.
従来、保温性布帛については、その性能を付与するためいろいろな提案がされており、保温性付与の方法としては、例えば、デッドエアーを形成して空気の対流による熱損失を防ぎ、保温性を高める方法が挙げられる。具体的には、毛布などのように起毛、立毛によりデッドエアーを形成させる方法、中空繊維を使用してデッドエアーを形成する方法がある（例えば、特許文献１参照）。 Conventionally, various proposals have been made for heat retaining fabrics in order to impart the performance thereof. As a method of imparting heat retaining properties, for example, dead air is formed to prevent heat loss due to air convection, and heat retaining properties are improved. The method of raising is mentioned. Specifically, there are a method of forming dead air by raising or raising like a blanket, and a method of forming dead air using hollow fibers (for example, see Patent Document 1).
また、太陽光などの赤外線を吸収する材料を布帛に付与して保温性を高める方法も知られている。具体的には、カーボンブラックや着色した金属酸化物、例えば、炭化ジルコニウムなどの赤外線を吸収する材料を繊維に練り込んだり塗布する方法がある（例えば、特許文献２参照）。 There is also known a method for improving the heat retaining property by applying a material that absorbs infrared rays such as sunlight to a fabric. Specifically, there is a method in which a material that absorbs infrared rays, such as carbon black or a colored metal oxide, for example, zirconium carbide, is kneaded or applied to a fiber (see, for example, Patent Document 2).
一方、透湿性防水布帛についても、その性能を付与するため、これまでにいろいろな提案がされており、透湿性および防水性を有する樹脂被膜を織物に付与することにより透湿防水性を付与する方法が挙げられる。具体的には、織物の片面に透湿性を有するウレタン樹脂溶液をコートし、乾燥して、透湿防水性布帛を得る方法や透湿性を有するウレタン樹脂被膜を離型紙の上に形成した後、接着剤で織物と貼り合せる方法、ウレタン樹脂溶液を織物の上に塗布した後、水中で凝固して多孔質の被膜を形成させる方法がある（例えば。特許文献３参照）。
しかしながら、デッドエアーを形成させた起毛織物やフリースを用いた衣服や赤外線を吸収する炭化ジルコニウムなど繊維に練り込んだ糸を用いた衣服では、風がないときは暖かいが、風が吹くと寒くなる為、上にコートなど防風素材の上着を着る必要があった。
また、上記の透湿性防水布帛では、雨や風により体温が奪われ寒さを感じることを防ぐことができるが、外気温が低い場合は、衣服内の温度は低く、防寒が必要なときに着用する衣服としては透湿性防水布帛を表地に用い、大量の中綿を用いた衣服の製造を行ったり、透湿性防水布帛を用いた衣服の下に多数の衣服を重ね着する必要があり、いずれにしても重く、厚く、スポーツ、登山、作業などには適さない衣服となってしまう。
そこで、本発明は上記事情を鑑みてなされたものであり、保温性に優れた透湿性防水布帛を提供することを目的としている。
However, in clothes using brushed fabrics and fleece that form dead air, and clothes using yarn kneaded into fibers such as zirconium carbide that absorbs infrared rays, it is warm when there is no wind, but it becomes cold when the wind blows. Therefore, it was necessary to wear a windproof material jacket such as a coat on top.
In addition, the moisture-permeable waterproof fabric described above can prevent the body temperature from being lost due to rain or wind, but it can be prevented from feeling cold, but when the outside air temperature is low, the temperature inside the clothes is low and it is worn when cold protection is required. As a garment to be worn, it is necessary to manufacture a garment using a large amount of batting using a moisture-permeable waterproof fabric as the outer material, or to layer a large number of clothing under the garment using the moisture-permeable waterproof fabric. Even if it is heavy and thick, it becomes clothes that are not suitable for sports, mountaineering, and work.
Then, this invention is made | formed in view of the said situation, and it aims at providing the moisture-permeable waterproof fabric excellent in heat retention.

Water pressure resistance: Measured according to the high water pressure method of JIS L1092 hydrostatic pressure method. When the test piece was stretched by applying water pressure, a nylon taffeta (vertical and horizontal density total of about 210 pieces / 2.54 cm) was placed on the test piece and attached to the tester for measurement. . In addition, for the sake of easy comparison with the low water pressure method, the unit converted to 9.8 kPa = 1000 mm of water column is also shown.
