Description of the Related Art In addition to keeping warm and cool equipment such as air conditioners and pipes, it is possible to prevent dew condensation on the surface of equipment made of metal or the like to cause dirt or corrosion or deterioration of the surface. Therefore, surfaces such as the inner and outer surfaces of these devices are covered with a heat insulating material for preventing dew condensation.

断熱材で結露の発生を確実に防止するには、発泡体の厚
みをかなり分厚くしておかなければならない。Conventionally, various materials such as synthetic resin foams, fiber materials, and metal foils have been used as a dew condensation-preventing heat insulating material alone or in a laminated body. In order to surely prevent the occurrence of dew condensation with the heat insulating material for preventing dew condensation, which is formed of a single layer of a synthetic resin foam which is generally well known, the thickness of the foam must be considerably increased.

解決する方法が種々提案されている。In recent years, there has been a demand for downsizing of devices such as air conditioners which are subject to dew condensation prevention and heat insulation, and it has become difficult to secure a sufficient space for disposing dew condensation preventing heat insulating material in these devices. It was Therefore, it is required to reduce the thickness of the dew condensation preventing heat insulating material without impairing the effects of heat insulation and dew condensation prevention. Various methods for solving such problems have been proposed.

熱材の厚みを薄くすることができるという技術である。In the method disclosed in Japanese Utility Model Publication No. 3-19677, a layer holding a water absorbing agent is provided on the outside of a heat insulating material made of foam. In this method, even if dew condensation occurs on the outer surface of the water-absorbent agent layer, the dew-condensation water is prevented from dripping by holding the dew-condensation in the water-absorbent agent layer. Moisture once absorbed in the water-absorbent agent layer is released from the surface of the water-absorbent agent layer when dew condensation stops. As a result, there is no need to increase the thickness of the heat insulating material made of foam in order to prevent dew condensation, and this is a technique that can reduce the thickness of the heat insulating material.

The fibrous web performs the same function as the water absorbent layer.

悪くなる。In the above-mentioned conventional technique, the water absorption function for absorbing dew is insufficient, or the means for holding the water absorption material is insufficient, so that the functions such as water absorption with time elapse. There was a problem that it declined. If the water absorption is insufficient or decreases over time, the dew condensation prevention function will deteriorate.

The water-absorbing agent falls off due to a decrease in the water-retaining function, and the water-absorbing function cannot be exhibited. Further, in the method of integrating the fibrous web with the foam by needle punching, a fibrous web made of synthetic fiber such as nylon is used as the fibrous web, but these fibrous webs do not have sufficient water absorption.
