て成る建築用と結露防止材に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an architectural and dew condensation prevention material made of a nonwoven fabric and a net-like material bonded together by thermocompression.

In recent years, buildings, especially houses, have become highly airtight, causing condensation on the walls and mold growth, which is not only unsanitary but also shortens the useful life of the building. Anti-condensation materials have been proposed. Particularly recently, walls have been constructed that have a layer of anti-condensation material on the indoor side and a ventilation path on the outside that allows indoor water vapor that has passed through the anti-condensation material layer to escape outside the wall. . Such dew condensation prevention materials are required to have excellent air permeability that allows only water vapor to pass through without allowing water droplets to pass through. In order to satisfy this requirement and to put it into practical use, the pore diameter must be approximately
It needs to be in the form of a sheet that has microporosity of 100 μm or less and is easy to install.

る。 As a conventional dew condensation prevention material, one side of a wallpaper base material is coated with finely divided vinyl chloride and then heated to weld the fine particles (Japanese Patent Laid-Open No. 59-88998).
(No.), and one in which foamed vinyl chloride nonwoven fabric sheets are laminated (Japanese Patent Application Laid-open No. 134739/1983) are known.

また、後者（特開昭59−134739号）においては、

きなセルが発生するという欠点があつた。 However, in the former method (Japanese Unexamined Patent Publication No. 59-88998), since the coating is performed using a liquid in which finely divided vinyl chloride is dispersed in water, plasticizer, etc., air bubbles may be mixed into the coating layer and cracking may occur during heating. pore size tends to become non-uniform.
In addition, in the latter (Japanese Patent Application Laid-Open No. 59-134739),
Since a foaming agent is mixed, there is a drawback that cells aggregate during foaming, resulting in large cells.

布（特開昭62−215057）等があつた。 In addition, the following prior art has been used as a condensation prevention material or a reinforced nonwoven fabric using a nonwoven fabric alone or a laminated fabric consisting of a nonwoven fabric and a net-like material. That is,
The former is an anti-condensation material made solely of a melt-blown nonwoven fabric with a fineness of about 1 d/f or less, and the latter is a web made of heat-adhesive composite fibers laminated with a net made of heat-adhesive composite monofilament. Non-woven fabrics reinforced by thermal bonding (Japanese Patent Application Laid-Open No. 62-215057) were available.

くて透水性となるという欠点があつた。 Although the dew condensation prevention material made of the melt-blown nonwoven fabric alone is microporous, its strength is too low. Also,
The above-mentioned reinforced nonwoven fabric has sufficient improvement in nonwoven fabric strength and is easy to install, but since it uses large fibers with a fineness of about 1.2 d/f or more as the web, it has the disadvantage that it is not microporous but water permeable. It was hot.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art and to construct a dew condensation prevention material that is microporous, has high strength, is easy to construct, and can be thermoformed.

合も含む。 That is, the present invention provides a nonwoven fabric made of thermoplastic resin fibers with a single filament fineness of 0.002 to 1.2 deniers (hereinafter sometimes referred to as microfiber nonwoven fabric), and a nonwoven fabric with a melting point that is 15° C. or more lower than the melting point of the thermoplastic resin fibers. The laminated cloth is a laminated cloth in which a net-like material consisting of yarn containing 30% by weight or more of heat-adhesive fibers having a thermoplastic resin as a heat-adhesive component is laminated and bonded under heat and pressure, and the thickness of the laminated cloth is The length is 0.1mm~2mm,
This anti-condensation material has properties such as bending resistance of 10 cm or more, porosity of 50 to 98%, breaking strength of 6000 g/5 cm or more, and moisture permeability of 500 g/m 2 24 hours or more. In the above, the laminated structure includes not only a case in which microfiber nonwoven fabrics are laminated on one or both sides of a net-like object, but also a case in which two or more microfiber nonwoven fabrics are laminated alternately.

構造は安定している。 The microfiber nonwoven fabric used in the present invention is composed of thermoplastic resin fibers having a single filament fineness of 0.002 to 1.2 deniers and manufactured by a melt blow spinning method as described in JP-A-50-46972. When the single fiber fineness exceeds 1.2 denier, the average pore size will be
When the porosity is 100 μm or more, the microporosity is poor, and conversely, when the denier is less than 0.002 denier, the nonwoven fabric has poor air permeability even if the porosity of the nonwoven fabric is in a low density state of 98% or more. Examples of the type of resin for the thermoplastic resin fiber include polyester, polyamide, and polyolefin resins. Each fiber made of these thermoplastic resin fibers has a unique melting point. At temperatures below this melting point, the thermoplastic fibers are solid and the structure of the microfiber nonwoven fabric is therefore stable.

改善することが出来ない。 The net-like material is made into a net-like material by knitting and weaving threads containing 30% by weight or more of heat-adhesive fibers (sometimes referred to as "net constituent threads").
The yarns constituting the net may be in various forms, such as spun yarn, multifilament, monofilament, etc., and the appropriate fineness is about 100 to 2000 deniers. If the content of thermoadhesive fibers in the net constituent yarns is less than 30% by weight, the thermal adhesion to the microfiber nonwoven fabric will be insufficient, so the stiffness of the dew condensation spun material,

と熱接着が可能である。 The heat-adhesive fibers contained in the net constituent yarns include homogeneous fibers consisting of a heat-adhesive component alone and composite fibers consisting of a heat-adhesive component and other components. The former includes homogeneous fibers whose main component is a thermoplastic resin such as low melting point polyester or polyolefin, or a mixture of two or more thereof. To further explain the latter, a sheath-core type or parallel type composite fiber is composed of two components with a melting point difference of 15°C or more, and a low melting point component that is a thermal adhesive component forms at least a part of the fiber surface. The combinations of the above two components include (polyester/polyolefin), (polyamide/polyolefin), (polyolefin/
Polyolefin) etc. are exemplified. The heat-adhesive components of these heat-adhesive fibers each have a unique melting point, and can be heated above this melting point to thermally bond to other objects.

るのである。 What should be noted here is that the melting point of the thermoplastic resin fibers constituting the microfiber nonwoven fabric and the thermoadhesive component of the thermoadhesive fibers contained in the net constituent yarns is 15°C or more lower than the melting point of the former. It is necessary to combine them in this way. The reason for this is that, as described later, the dew condensation prevention material of the present invention is produced by heat-pressing a microfiber nonwoven fabric and a net-like material in a laminated state, and at that time, the heat-adhesive fibers contained in the net constituent yarns are bonded together. The heat-adhesive component is in a molten state and the two are integrated by adhesion, but it is clear that the microfiber nonwoven fabric maintains its microporous structure even after heat-pressing. Therefore, the melting point of the thermoadhesive component is selected to be 15°C or more, preferably 20°C or more lower than the melting point of the thermoplastic resin fibers constituting the microfiber nonwoven fabric.

し、残余は加熱圧着温度においても全く溶融しな
い他の繊維が混合されている。 As mentioned above, by combining thermoplastic resins and applying heat and pressure at a temperature between the melting points of the two (including the lower melting point), the structure of the microfiber nonwoven fabric is maintained, but at the same time, the structure of the microfiber nonwoven fabric is maintained. It is necessary to maintain its shape, and for this purpose, if the heat-adhesive fibers are composite fibers, all of the fibers that make up the net (or themselves in the case of monofilament) must be heat-adhesive fibers. If the thermobondable fiber is a homogeneous fiber, the content in the net constituent threads should be at most 80%, and the remainder is mixed with other fibers that do not melt at all even at the heat-pressing temperature.

るのである。 As mentioned above, the dew condensation prevention material according to the present invention, in a state in which the microfiber nonwoven fabric and the net-like material are laminated, has a temperature lower than the melting point of the thermoplastic resin fibers constituting the microfiber nonwoven fabric. By heat-pressing the adhesive fibers to a temperature higher than the melting point of the heat-adhesive component, the molten heat-adhesive component in the threads of the net penetrates into the microfiber nonwoven fabric in the thickness direction at many locations. The microfiber nonwoven fabric and the net-like material are obtained in an integrated state by thermally adhering them to the thermoplastic resin fibers constituting the microfibers.

である。 The degree of thermocompression bonding between the net-like material and the microfiber nonwoven fabric can be adjusted by selecting thermocompression bonding conditions such as heating temperature and pressure from the above ranges. The thermocompression bonding may be performed using various existing devices such as a hot calender roll or a hot press. An example of generally preferable thermocompression bonding conditions when using a calendar roll is that the fibers constituting the microfiber nonwoven fabric are polyester fibers or polypropylene fibers, and the thermoadhesive fibers contained in the net constituent yarns are polypropylene/polypropylene fibers.
For polyethylene composite monofilament, the roll temperature is approximately 120-140℃ and the linear pressure is approximately 2-120Kg/cm.
It is.

成されないのである。 By integrating the microfiber invar nonwoven fabric and the net-like material as described above, the bond between the two becomes extremely strong, increasing the strength.
Since the two do not separate even when bent, it is easy to thermoform, and the excellent microporosity of the nonwoven fabric, which is made of single-filament thermoplastic resin fibers with a denier of 0.002 to 1.2 denier, is maintained using the melt blow spinning method. It became a thing. Further, numerous tests have shown that in order to be easy to handle, easy to install, and have great strength, the overall thickness of the condensation prevention material must be 0.1 mm to 2 mm, the bending resistance must be 10 cm or more, and the porosity must be 50 mm.
~98%, breaking strength over 6000g/5cm, moisture permeability
It was found that the best material was one with a property of 500 g/m 2 ·24 Hr or more. If the properties are other than the above, the object of the present invention cannot be achieved because the breaking strength is too low, the rigidity is insufficient, or the moisture permeability is insufficient.
