とが理想的である。In the latter method, the resin solution is applied to the release paper by means such as knife coating to form the film 2, and then
It has been found that forming the film 2 on the surface of the base fabric 1 by removing the release paper while adhering the film 2 side to the surface of the base fabric 1 is a practical method. When using this film lamination method, the film 2 formed on the surface of the base fabric 1
Since the surface of the film 2 is the peeling surface from the release paper, a thin resin skin layer is likely to be formed on this surface, so it is ideal to perform a sanding treatment on the surface of the film 2. or,
In order to prevent the moisture permeability from being inhibited by the adhesive layer interposed between the base fabric 1 and the coating 2, the gelatin particles 3...3 are mixed into the adhesive solution forming this adhesive layer. Ideally, it should be left in place.

The temperature setting of the hot water or boiling water used and the setting of the soaking time are determined at any time depending on the material characteristics of the base fabric 1 and the material characteristics, thickness, etc. of the film 2 formed on the surface of the base fabric 1. There is a need. Also, this temperature setting and soaking time setting are based on the gelatin particles 3 contained in the film 2.
. . .3 may be changed at any time depending on the extent to which 3 is to be eluted. This means that the film 2 formed on the surface of the base fabric 1
This is to cope with the case where the desired moisture absorbing function is provided to the surface of the film 2 while making the air permeability of the film 2 itself more restrictive by removing a part of the gelatin particles 3.

In the elution method that leaves a part of gelatin particles 3...
- The number of pores 4 that are generated due to the elution of pores 4 is limited, and the gelatin particles 3 that remain in some of the pores 4 narrow the pore diameter of the pores 4, which significantly limits air permeability. As a result, the film 2 has a heat insulating effect. At the same time, since the gelatin particles 3...3 left on the film 2 have a moisture absorbing function, the moisture in the base fabric 1 is absorbed and the moisture permeability of the film is radiated outward through the film 2. 2.

・By eluting 3, countless pores 4...4 with a pore diameter smaller than 3 to 50 gm are provided in the film 2, and these countless pores 4...4 are evenly distributed over the film 2. In particular, if the gelatin particles 3...3 are not completely eluted and some of them remain, the pores formed in the film 2 will have a finer pore diameter. 0.5 g m~1
Pores 4 with a fine pore diameter of 0 gm were created.

After forming a film 2 on the surface of the base fabric ↓ in advance, the gelatin particles 3...3 contained in this film 2 are eluted, so the film 2 can be easily formed and has a uniform thickness. Film 2 can be created. As a result, the coating 2 is not damaged due to wear, and the base fabric l
The coating 2 is formed over the entire surface of the base fabric 1, and there is no surface of the base fabric l that is not covered with the coating 2.

The pore diameter of the hole 4 is smaller than at least 50 gm, and “
In many embodiments, the pore diameter is around 1 o-, h'm, so water droplets etc. do not pass through, and the pores have a complete waterproof function. This means that the size of a typical rain droplet is 200
This is well understood since the particle size is approximately 100 gm even in drizzle, which has a particularly fine particle size. On the other hand, the particle size of water vapor such as sweat released from the human body is as small as 0.0004 p-m.
It is easily radiated to the outside through the hole 4 having a hole diameter of about 0.04t. As a result, the inside of the waterproof fabric does not get stuffy and can be used for various sports wear and various rain gear that are particularly susceptible to sweating.
