More specifically, the moisture-permeable waterproof sheet of the present invention is waterproof and has moisture permeability that allows water vapor to pass through freely, and can be used for clothing such as sportswear, diapers, rainwear, etc. It can be used in a wide range of applications, including building materials such as wall and ceiling materials, and living-related materials such as base materials for dehumidifiers.

生活関連材料への用途に展開することが難かしかった。Moisture-permeable waterproof sheets are generally made by coating a fiber base fabric with a solvent-based resin to form pores in the resin film that are smaller than the particle size of rainwater and larger than water vapor, or by coating the resin with hydrophilic groups. It is manufactured using methods such as polymerization to transfer water vapor, but the resin and processing costs are high, and although it can be used for expensive clothing such as sportswear, it is an inexpensive building material.
It was difficult to develop it into applications for everyday life-related materials.

があシ用途限定が余儀なくされていた。In addition, moisture-permeable waterproof sheets using water-based resins have disadvantages in that the drying efficiency for removing water and forming a resin film is inferior to that of solvent-based sheets, and processing costs are high due to decreased productivity. Limitations were forced.

として(ま−特開昭57−143514号公報がある。In the present invention, a nylon filament melt-spun at a high speed of 4 ooom/min or more is used, and a typical manufacturing method thereof is disclosed in Japanese Patent Application Laid-Open No. 143514/1983.

安価なシートを得ることができる。In manufacturing the moisture-permeable waterproof sheet of the present invention, the above-mentioned characteristics are utilized, and it has the characteristics that it can be subjected to high temperature treatment during drying when forming a water-based resin film, and can be processed at high speed. In particular, it significantly improves productivity when processing conventional moisture-permeable waterproof sheets using water-based resins.

塗布し乾燥して透湿防水シートを得ることができる。In addition, fiber base fabrics made of filaments spun at a typical speed of about 1000 rn/min cannot be produced if a resin solution is applied in the gray state and dried, and the width changes due to large heat shrinkage. It was necessary to stop the shrinkage of the gray fabric before processing it, but the present invention's 40
Since the fiber base fabric made of filaments spun at 00 m/min or more has a small thermal shrinkage rate, a moisture-permeable waterproof sheet can be obtained by applying a resin solution in the state of t=grey and drying.

Formalin-based resins, glyochidyl-based resins, etc. can be used, and preferably two or more types can be used in combination. In addition, crosslinking agents, flame retardants, thickeners, fillers, foaming agents, and colorants can be added as necessary.The amount of resin applied will affect moisture permeability and waterproofness, and If it is too low, the moisture permeability will be good but the waterproofness will be poor.
Also, if the coating amount is too large, the waterproofness will be good but the moisture permeability will be significantly reduced, so the coating amount should be 3 to 20g/m".
Preferably it is 5 to 10 g/m2.

小さくする方法などがある。When manufacturing the moisture-permeable waterproof sheet according to the present invention using a coating method in which a resin solution is applied to a fiber base fabric, when the resin solution is applied to the fiber base fabric, the resin solution penetrates into the inside and back surface of the fiber base fabric.1. It is preferable to pre-treat the fibrous base fabric in advance, since the resin film formation is poor and the waterproof properties are unfavorable. Treatment methods for this include, for example, treating the fiber base fabric with one type or a combination of two or more water repellents such as fluorine-based, silicone-based, zirconium-based, or wax-based water repellents, or passing the fiber base fabric through a calendar to remove the fibers. There are methods to reduce the pores on the surface of the fiber base fabric by crushing the bulge in the base fabric.
