However, in the conventional technology as described above, the moisture permeability is mainly determined by JIS Z 208 or J
It was measured by the IS L 1099 calcium chloride method, but from the perspective of the true comfort of the garment, the movement of water vapor to a dry environment simply because of the humid conditions in the garment. The method using calcium chloride assuming the above is not sufficient. When exercising while wearing clothes, the inside of the clothes is humid, and the outer surface temperature of the clothes is lower than that of the clothes, so water droplets are generated inside the clothes. Adhere to. In such a state, no matter how constant temperature (calcium chloride method), it shows remarkable moisture permeability,
When there is a temperature difference between the outside air and the inside of the clothes, water droplets are generated and adhere, and therefore, it is necessary to have a performance of effectively releasing the adhered water droplets mainly to the outside of the clothes. Therefore, the magnitude of the moisture permeability measured by the potassium acetate method is rather closely related to the true comfort in clothes. This is the same for tents and sleeping bags.

It is preferable to have a porous membrane. As the microporous membrane containing a polyurethane resin as a main component, any known polyurethane resin, an amino acid-modified polyurethane resin, a fluorine-containing polyurethane resin, a urethane resin having a high glass transition point and a high temperature sensitivity, and the like can be used. Although not particularly limited, a fluorine-containing polyurethane resin is particularly preferably used.

In many cases, the durability is slightly inferior to the film obtained by the lamination method. In addition, tack tends to occur. In the case of the lamination method, a non-porous film having a smooth film surface and a uniform film thickness is obtained for forming a film on release paper, so that a durable and stable quality fabric can be obtained. It can be manufactured stably. Furthermore, in the method of applying a moisture-permeable adhesive in the form of dots or lines and performing bonding, it is possible to obtain a cloth having excellent moisture permeability as compared with the case where the entire surface is bonded, and without using an adhesive. The moisture-permeable waterproof fabric obtained by thermocompression bonding exhibits remarkably excellent performance in all of waterproofness, moisture permeability and durability, and has a water pressure retention of 90% or more even after washing 10 times.
