Therefore, the interfiber voids of the nonwoven fabric can be several microns or less. M from hydrophobic resins such as polypropylene
If B nonwoven fabric is made, a nonwoven fabric that has breathability and a certain degree of waterproofness, that is, water resistance as referred to in the present invention, can be obtained.
一方ＭＢ不織布は構成繊維の分子配向が、汎用繊維に比

Non-woven fabrics and strong spunpond non-woven fabrics are fused together and used in work clothes, surgical gowns used in hospitals, drapes, sterilization wraps, etc. In this way, by laminating the MB nonwoven fabric and the spunpond, it is possible to obtain a composite sheet that has sufficient strength, air permeability, and high water resistance. However, if high water resistance is required, the current situation is that the sheet surface must be water repellent. For example, if a MB nonwoven fabric made of polypropylene with a water resistance of 65 crrl is sandwiched between nylon spunpons coated with a hydrophilic oil agent, and the three layers are fused together, the surface will certainly be hydrophilic and absorb liquid. However, the water resistance drops to about 3 cm. In other words, the current situation is that if the surface is made hydrophilic, the water resistance will decrease.

That is, at least one surface is covered with a hydrophilic nonwoven fabric having a surface water repellency of 70 points or less, and the nonwoven fabric layer and a layer containing a web having a water resistance of 50 cm or more have an average moisture content of 3% or less. It has a hydrophilic surface characterized by being integrally bonded discontinuously with an adhesive resin and has a water resistance of 50c.

Even if the fibers on the surface are hydrophobic, a surface material with a water repellency of 70 points or less can be obtained by adding a hydrophilic surfactant or incorporating a hydrophilic component. In the present invention, the water repellency is preferably at least 70 points or less, but if hydrophilicity and liquid absorption are particularly desired, the water repellency is more preferably lower than 30 points.

明の効果は一層大きいものになる。Next, a nonwoven fabric having a water resistance of 50 cm or more can be easily obtained by making a polyolefin resin, typified by polypropylene, with a moisture content of about 0% into a nonwoven fabric by the MB method. At this time, if the average fiber diameter is set to 10 microns or less, or even several microns or less, an MB nonwoven fabric with high water resistance can be obtained. Further, by flat heat calendering, it is possible to improve water resistance while maintaining moisture permeability and air permeability. In order to obtain an MB nonwoven fabric having the water resistance required for the present invention, the basis weight of the nonwoven fabric must be 15 g/m2 or more. By adjusting factors such as the diameter of the fibers constituting the MB nonwoven fabric, thermal calendar treatment, and basis weight, it is possible to improve water resistance while maintaining moisture permeability and air permeability, and the effects of the present invention are further enhanced. It becomes something big.

の繊維の融点よりも低いことがさらに好ましい。In order to integrate the hydrophilic surface material and the layer containing the MB web, an adhesive resin having an average moisture content of 3% or less, preferably 1% or less, is applied in a discontinuous manner so as not to form a film. , the surface material and the layer containing the MB web are interposed between the surface material and the layer containing the MB web, pressure is applied, and if necessary, heating and pressure is applied to bond the surface material and the layer containing the MB web. As the adhesive resin, an olefin resin or acrylic resin into which a functional group is introduced is used. Adhesion can be achieved by chemical or physical methods, including fusion, adhesion, etc., or by a combination of these mechanisms. When a thermoplastic resin having a melting point is used as the adhesive resin, the melting point is preferably lower than the softening point of the MB resin (the temperature at which changes begin in differential thermal analysis), and the composition of the surface material contains thermoplastic fibers. If the melting point is lower than the melting point of the fiber, it is more preferable.

が低下するので好ましくない。In order to prevent the composite sheet of the present invention from losing its moisture permeability, the adhesive resin needs to be interposed continuously between the surface material and the layer containing the MB web, i.e. discontinuously so as not to form a film. . In addition, the equilibrium moisture content of the adhesive resin is 3
%, it is not preferable because the water resistance of the obtained nonwoven fabric composite sheet decreases.
