When the moisture permeability is imparted by the holes formed in the film, it is difficult to make the moisture permeability and the waterproof property compatible with each other at the same time because the holes cause the deterioration of the waterproof property. In addition, the holes formed in the film are apt to be clogged by stains during use, and the performance such as moisture permeability is likely to deteriorate. Further, when a filler is added to the film raw material and pores are created by voids generated during stretching, the film surface is likely to be roughened by the filler, and the obtained film is inferior in surface flatness and texture.

The non-porous film generally has a low moisture permeability as compared with the porous film, and it is difficult to obtain a highly moisture-permeable material.

Further, the conventional method of laminating the film and the non-woven fabric is a method of laminating with an adhesive, and there is a drawback that the moisture permeability is lowered by the adhesive. Further, in the case of a thin film, problems such as film breakage and wrinkles are likely to occur in the bonding process, resulting in a decrease in yield.

Further, the molecular weight of the polyalkylene oxide moiety is preferably 500 or more, and further, the polyalkylene oxide moiety is preferably composed of polyethylene oxide and / or polytetramethylene oxide.

-Hydroxyethoxyphenyl) propane and their ester-forming derivatives can be mentioned. These components may be used alone or in combination of two or more. The polyester composition mainly composed of polyethylene terephthalate in the present invention can be produced by a conventionally known method. For example, a method in which a dicarboxylic acid component and a diol component are directly esterified, and then the reaction product is heated under reduced pressure to distill the diol component to cause polycondensation, or an ester of the dicarboxylic acid component. There is a method in which the forming derivative and the diol component are esterified by a transesterification reaction and then polycondensed in the same manner as above. At this time, the necessary copolymerization component is added at a necessary time. In addition, if necessary, a conventionally known alkali metal, alkaline earth metal, manganese, cobalt, zinc as a reaction catalyst,

One type or two or more types of lubricants such as wax and defoaming agents such as polysiloxane can be blended.

The substantially non-porous film made of a thermoplastic resin in the present invention means that the opening area of the holes penetrating the film includes the opening area of the holes in a continuous area of a square on the film surface. 5% of film surface area
Or less, preferably 1% or less, more preferably 0.1%
It is a film which is the following, in the present invention, the holes,
Preferably, the equivalent circle diameter is 0.1 μm or more. Although the thickness of the film can be freely selected depending on the application, it is preferably 10 μm or less, more preferably 5 μm or less, and particularly preferably 3 μm or less in order to improve the moisture permeability.

Further, the substantially non-porous film made of the thermoplastic resin of the present invention may be either a single layer film or a laminated film, but in order to prevent the high moisture permeable film from sticking during the melt film formation, It is preferably a laminated film. The laminated film preferably has a surface layer made of a polymer having a high glass transition point and a core made of a polymer having a higher moisture permeability. By reducing the film thickness of the surface layer portion, a highly moisture-permeable film having high film-forming stability can be obtained as a whole film. The constitution of the laminated film is preferably a three-layer laminated structure having a polymer having a low glass transition point as a core, but a laminated film having more layers may also be used. The laminated film uses 2-3 extruders,
It can be manufactured by stacking a film using a multi-layer confluent block having three or more layers or a die.

The non-woven fabric in the present invention is a non-woven fabric made of fibers such as polyolefin, polyamide, polyester and the like, more preferably a non-woven fabric made of polyester continuous fibers mainly composed of polyethylene terephthalate and polyethylene naphthalate, and particularly preferred. Is preferably a non-woven fabric composed of polyester filaments mainly composed of polyethylene terephthalate. The polyester continuous fiber mainly composed of polyethylene terephthalate in the present invention is a polyester continuous fiber having 70% by weight or more of ethylene terephthalate repeating units among the polyester molecular repeating units.

The non-woven fabric of the present invention can be produced by a conventionally known flash spinning method, melt blow method, spun bond method, needle punch method, spun lace method, or the like. For example, in the melt blow method, when the molten polymer is discharged from the die, hot air is blown from a peripheral portion of the die to make the discharged polymer finer, and then sprayed onto a net conveyor arranged at an appropriate position. It is manufactured by collecting and forming a web. Since the web is sucked together with the hot air by the suction device provided on the net conveyor, it is collected before the fibers are completely solidified. That is, the fibers of the web are collected while being fused to each other. By appropriately setting the collection distance between the base and the net conveyor, the degree of fusion of the fibers can be adjusted. Further, by appropriately adjusting the polymer discharge amount, the hot air temperature, the hot air flow rate, the conveyor moving speed, etc., the fiber areal weight of the web and the single yarn fineness can be arbitrarily set. The fibers melt-spun are finely densified by hot air pressure, but are not stretched and solidified in a so-called non-oriented state. The thickness of the fibers is not uniform, and the web is formed in a state in which the thick fibers and the thin fibers are appropriately dispersed. In addition, the polymer discharged from the base is
Since it is rapidly cooled from the molten state to a room temperature atmosphere, it solidifies in a state close to an amorphous state.

Similarly, in the spunbond method, the polymer discharged from the die is pulled by an air ejector, and the obtained filament is collided with a collision plate to open the fiber,
It is manufactured by collecting it on a conveyor to form a web. By appropriately setting the polymer discharge amount and the conveyor speed, the fiber basis weight of the web can be arbitrarily set. In addition, the molecular orientation of the filament can be arbitrarily adjusted by appropriately adjusting the pressure and flow rate of the air ejector.
A fiber web with a low degree of molecular orientation can be obtained by reducing the spinning speed by reducing the pressure and the flow rate. Also,
By adjusting the cooling rate of the discharged polymer, it is possible to obtain a fibrous web having different crystallinity.

The laminate of the present invention is a laminate in which a thermoplastic resin film and a non-woven fabric are laminated, and a two-layer laminate of the film and the non-woven fabric or a three-layer laminate such as film / non-woven fabric / non-woven fabric / film / non-woven fabric. Examples thereof include a body and a multilayer body having more layers. Further, if the film part and the non-woven fabric part of the laminate are composed of a polyester composition mainly composed of polyethylene terephthalate, it is possible to collect and recycle the film, the non-woven fabric and the laminate without the need for separation, and the laminate is inexpensive. It is also preferable in terms of environmental problems, since it can be manufactured at a low cost and the generation of scraps is reduced.

The water vapor transmission rate of the laminate of the present invention means JI
24 times the moisture permeability of the SL-1099 A-1 method,
The water vapor permeability converted per day (24 hours), which is 1000 g / (m ² · day) or more, preferably 3000 g / (m ² · day) or more, and more preferably 5000 g / It is (m ² · day) or more. When the moisture vapor permeability is less than 1000 g / (m ² · day), it is difficult to use it as a moisture permeable material. Further, the water resistance of the laminate of the present invention means JIS-L-
1092 is the water resistance according to the water resistance test A method (hydrostatic pressure method), and the water resistance is 500 mm or more, preferably 1
It is 000 mm or more, more preferably 2000 mm or more. If the water resistance is less than 500 mm, the waterproof property is insufficient and it is difficult to use it as a waterproof material.

The method for producing a laminate of the present invention is characterized in that a thermoplastic resin is formed into a film by a melt extrusion method, the thermoplastic resin film and a nonwoven fabric are laminated by thermal adhesion, and then stretched in at least one axial direction. This is a method for producing a moisture-permeable and waterproof laminate, and biaxial stretching is particularly preferable.
By heat-bonding the film and the non-woven fabric, no adhesive is required, and since the film is stretched at least uniaxially after lamination, a laminate having a small thickness and excellent mechanical properties can be easily manufactured. As the melt extrusion method in the production method of the present invention, a conventionally known method in which a thermoplastic resin melted by heating with a uniaxial or biaxial extruder is discharged from a slit die to a casting drum to form a film can be used. The thickness of the film can be adjusted by adjusting the discharge rate of the molten thermoplastic resin, the slit size of the die, and the rotation speed of the casting drum. The heat adhesion between the film and the nonwoven fabric can be achieved by stacking the film and the nonwoven fabric while heating. For example, thermal bonding can be performed by sending a film and a non-woven fabric between heated rolls and applying pressure. In the production method of the present invention, the film and the nonwoven fabric are laminated and then stretched in at least a uniaxial direction. The stretching method may be roll stretching utilizing the peripheral speed difference of rolls or a tenter system. As the biaxial stretching method, either a sequential biaxial stretching method or a simultaneous biaxial stretching method may be used. In the sequential biaxial stretching method, generally, the stretching in the machine direction is performed and then the stretching in the transverse direction,
It doesn't matter even if the order is reversed. In addition, the stretching ratio for biaxial stretching is not particularly limited, but usually about 2 to 5 times is appropriate. After biaxial stretching, it may be stretched again in the machine direction and / or the transverse direction, if necessary. Furthermore, it is preferable to heat-treat the biaxially stretched laminate, and it is preferable to perform the treatment at a temperature not higher than the melting point of the fibers constituting the nonwoven fabric for 0.5 seconds to 60 seconds.
