ブロー不織布を衛生用品の表面材として用いた場合には
強度が低いという欠点があったのである。In recent years, spunbond nonwoven fabrics and meltblown nonwoven fabrics have been used as surface materials for sanitary products such as disposable diapers. An example of using a spunbond non-woven fabric is described in Japanese Utility Model Publication No. 59-9620, and an example of using a melt-blown non-woven fabric is described in JP-A-62-29.
It is described in Publication No. 9501. Spunbond nonwoven fabric is obtained by directly accumulating continuous fibers that are spun from a polymer stock solution and then drawn. The manufacturing method of spunbond nonwoven fabric is known, for example,
It is described in Japanese Patent Publication No. 7-4993, Japanese Patent Publication No. 49-30861, etc. The continuous fibers that make up the spunbond nonwoven fabric are stretched, and the polymer chains are oriented and have a high degree of crystallinity, so they exhibit high strength. Therefore, the spunpond nonwoven fabric itself has the advantage of varying strength. Taking advantage of this advantage, it is used as a surface material for sanitary products, but on the other hand, it has the disadvantage of being unpleasant to the touch. This is because it is difficult to obtain ultrafine fibers in the production of spunbond nonwoven fabrics, and the surface cannot be finished smoothly. On the other hand, melt-blown nonwoven fabric is made by blowing a stock solution of the same molecule through pores with a high-speed gas (for example, heated air) and collecting the resulting ultrafine fibers. Methods for producing melt-blown nonwoven fabrics are also known and are described, for example, in Japanese Patent Publication No. 56-33511 and Japanese Patent Publication No. 62-2062. The fibers constituting the melt-blown nonwoven fabric have a fiber diameter that is very small for boat fishing. Therefore, the surface of the melt-blown nonwoven fabric has the advantage of being excellent in smoothness and having a good texture. However, the ultrafine fibers constituting the melt-blown non-woven fabric are not sufficiently drawn during manufacture and have low strength, and therefore the melt-blown non-woven fabric itself has a disadvantage of having low strength. That is, when spunbond nonwoven fabrics are used as surface materials for sanitary products, they have the disadvantage of being uncomfortable to the touch, and when melt-blown nonwoven fabrics are used as surface materials for sanitary products, they have the disadvantage of low strength.

品の表面材を提供しようとするものである。In order to eliminate these drawbacks, it is thought that by laminating spunbond nonwoven fabrics and meltblown nonwoven fabrics, a surface material with good texture and high strength can be obtained (for example,
(See Japanese Patent Publication No. 60-11148). However, melt-blown nonwoven fabrics have low strength;
It has been difficult to apply it to the process of laminating spunbond nonwoven fabrics. Furthermore, even if melt-blown nonwoven fabric and spunbond nonwoven fabric are bonded together with adhesive,
Due to the presence of the adhesive, the resulting surface material was hardened as a whole, resulting in poor texture and poor texture. Furthermore, it is also possible to obtain a surface material by softening or melting either the melt-blown nonwoven fabric or the spunbond nonwoven fabric and bonding them together under heat, but the softened or melted nonwoven fabric may harden and its texture may deteriorate. There were cases where the skin became irritated. Therefore, the present invention aims to provide a surface material for sanitary products that has high strength and feels good on the skin by bonding spunbond nonwoven fabric and null 1-blown nonwoven fabric using a specific method to avoid deterioration in texture. It is something to do.

A spunbond nonwoven fabric with a basis weight of 8 to 28 g/bo obtained by accumulating polyolefin continuous fibers of 1 to 4 deniers and 1
A laminate of a melt-blown nonwoven fabric with a basis weight of 0.2 to 10 g/nr obtained by spraying and accumulating polyolefin ultrafine fibers of less than denier, wherein the spunbond nonwoven fabric and the melt-blown nonwoven fabric are bonded before accumulation. The present invention relates to a surface material for sanitary products such as disposable diapers, and a method for producing the same, which is produced by contacting the polyolefin microfine fibers with the polyolefin continuous fibers while the polyolefin microfine fibers are sticky. First, in the present invention, a spunbond nonwoven fabric is prepared. This spunbond nonwoven fabric is made by integrating polyolefin continuous fibers of 1 to 4 deniers. When using the spunbond method, it is difficult to obtain polyolefin continuous fibers of less than 1 denier. Furthermore, if the polyolefin continuous fiber exceeds 4 denier, the stiffness of the fiber increases, leading to a decrease in hand feel, which is not preferable. The basis weight of the spunbond nonwoven fabric is 8 to 28 g/m2. If the basis weight is less than 8 g/m2, the nonwoven fabric becomes thin and its strength decreases, which is not preferable. Also, the basis weight is 28 g
/rd is not preferable because the permeability of urine etc. is inhibited. Polyolefin ultrafine fibers obtained by a melt blow method are sprayed onto the surface of this spunbond nonwoven fabric to bond the melt blow nonwoven fabric together. The polyolefin ultrafine fiber obtained by the melt-blowing method has a denier of less than 1 denier. If the ultrafine fibers are 1 denier or more, the smoothness of the surface of the melt-blown nonwoven fabric obtained by accumulating the ultrafine fibers is undesirable. Moreover, the basis weight of the melt-blown nonwoven fabric is 0.2 to 10 g/rrt'. The basis weight is 0.
If it is less than 2 g/m, the nonwoven fabric will be too thin and the poor surface smoothness of the spunbond nonwoven fabric will manifest itself, which is not preferable. On the other hand, the basis weight is 10g/! If it exceeds d, the permeability of urine etc. will be inhibited, which is not preferable. Here, it is important in the present invention that the ultrafine fibers obtained by the melt blowing method are blown onto the surface of the spunbond nonwoven fabric and come into contact with the continuous fibers while they are still sticky. As a result, the ultrafine fibers adhere to the continuous fibers constituting the spunbond nonwoven fabric due to their adhesive properties, and the ultrafine fibers are accumulated on the surface of the spunbond nonwoven fabric to form a meltblown nonwoven fabric. Furthermore, since both the ultrafine fibers and the continuous fibers are polyolefin-based, they have good affinity and the adhesive strength between them is high, resulting in good bonding strength. The thus obtained laminate of spunbond nonwoven fabric and meltblown nonwoven fabric can be used as a surface material for sanitary products, either as it is or after being subjected to post-processing. As post-processing, heating or pressure treatment may be performed between rolls in order to improve the stability of the surface of the laminate. Alternatively, the spunbond nonwoven fabric and the meltblown nonwoven fabric may be partially bonded together by performing partial thermocompression bonding (embossment) to increase the bonding strength of the laminate. Furthermore, a surfactant may be added to improve the water permeability of the laminate, and a softener may be added to improve the flexibility of the laminate. Further, a small amount of adhesive may be applied to suppress fuzzing on the surface of the laminate. The surface material according to the present invention is made of a laminate of a spunbond nonwoven fabric and a meltblown nonwoven fabric, and is used as a surface material for sanitary products with the meltblown nonwoven fabric side in contact with the skin.

効果を奏する。As explained above, the surface material of the 111 household goods according to the present invention is made of a laminate of a specific spunbond nonwoven fabric and a specific null 1-blown nonwoven fabric, so the spunbond nonwoven fabric has high tensile strength and bulk. It imparts surface flexibility and good texture and texture to melt-blown nonwoven fabrics. Therefore, if the melt-blown nonwoven fabric is placed on the side that comes into contact with the skin and used as a surface material for sanitary products, it will have the effect of being resistant to tearing and having a good texture. Then, the spunbond nonwoven fabric and the meltblown nonwoven fabric come into contact with the continuous fibers constituting the spunbond nonwoven fabric while the ultrafine fibers blown by the meltblowing method are still sticky. In addition, since both the ultrafine fibers and the continuous fibers are polyolefin-based and have good compatibility with each other, both fibers adhere firmly. Therefore, the spunbond nonwoven fabric and the meltblown nonwoven fabric are laminated and bonded without using an adhesive or by softening or melting either of the nonwoven fabrics. Therefore, both nonwoven fabrics can be laminated and bonded without impairing the overall texture, and the overall texture of the obtained surface material is also good. In addition, the method for manufacturing the surface material of sanitary products according to the present invention is a method in which microfibers obtained by melt blowing are sprayed on the surface of spunbond nonwoven fabric in a specific state, so spunbond nonwoven fabric and meltblown nonwoven fabric are There is no need to create them separately. Therefore, the method for manufacturing a surface material for sanitary products according to the present invention has the advantage that the process can be streamlined.
