Description of the Related Art As for a stretchable nonwoven fabric, Japanese Patent Laid-Open No. 4-257363 discloses a needling laminate of a crimpable short fiber web and a urethane nonwoven fabric. Since the web of this non-woven fabric is made of crimped short fibers, the web itself has elasticity, and even if the web is repeatedly stretched, peeling between the web and the urethane non-woven fabric is less than that of a non-woven fabric using a short-crimped web. However, in this method, since the short fiber web remains only by the entanglement of the fibers, there is a drawback that hair loss due to friction occurs.

Examples thereof include polyester, nylon, acrylic, polyethylene, polypropylene, rayon, urethane, and cotton, but are not limited thereto. Among them, a material having a strong crimp is preferable because the web itself has elasticity. Further, a conjugate fiber or the like in which crimp is developed by heat or the like is preferable. For example, the high crimped polyester fiber has a product number “C81” manufactured by Kanebo Co., Ltd., and the polypropylene high crimped fiber has a product number “UP” manufactured by Kanebo Co., Ltd.

The cut length of the short fibers is not particularly limited as long as it is a length suitable for general nonwoven fabrics. A length of 32 to 64 mm is often used. Denier is not particularly limited. Any denier suitable for general nonwoven fabrics may be used. That is, denier, mixed cotton, fabric weight, etc. may be appropriately selected depending on the texture of the product. In order to develop the crimp of the short fibers, it can be developed by hot air, but it may be after or before the three layers are laminated.

If this temperature difference is small, the short fiber web and the elastomer nonwoven fabric adhere to each other and the stretchability is hindered.

に配慮する必要がある。Unless the adhesive for fixing the third layer short fibers is partially performed in the form of dots, the elasticity of the short fiber web is lost and the elasticity of the elastomer nonwoven fabric is also impaired. Therefore, it is necessary to sufficiently secure the distance between the bonding points by spraying, embossing, or the like. However, in order to fix by heat fusion, binder fibers are mixed, and when the binder fibers are highly crimped fibers, it is possible to retain a large amount of elasticity within the range of the crimp ratio, so that the distance between the bonding points can be set to the normal fiber. It can be shorter than when used. It is preferable that the layer to which the binder fibers are adhered is an elastomer because the texture is soft. The adhesive for fixing is not particularly limited, but similarly, an elastomer adhesive such as urethane and vinyl acetate is preferable since it has a soft texture. The adhesive strength of the nonwoven fabric of the present invention also depends on the degree of mechanical entanglement. If it is too strong, the stretchability will be impaired, so it is necessary to take appropriate consideration depending on the application.

適当に配慮する必要がある。The embossing strength for heat fusion fixing depends on the blending amount of the heat fusion fibers, the bonding temperature, the pressure, the shape of the embossing, the depth, the area and the like. The adhesive strength also depends on the degree of mechanical entanglement. If it is too strong, it will hinder the elasticity.
Appropriate consideration is required.

機械方向の伸縮性が低くなる。The method for producing the short fiber web used for the first layer and the third layer is not particularly limited, but a general random web, a crosslay method or the like may be used. In the case of a random web, the stretchability of the web has no anisotropy. In the case of cross lay, the stretchability in the machine direction is low.

うに針の伸度等を調節し、第３層を形成させてもよい。The short fiber web of the first layer may be penetrated through the elastomeric nonwoven fabric of the second layer and entangled by a mechanical method such as needle punching or spunlace method. The short fiber web may be laminated differently from the first layer and the third layer, and the elongation of the needle may be adjusted so that the short fibers of the first layer penetrate more of the second layer, and the third layer may be formed. It may be formed.

により適宜選択する必要がある。For example, the needling direction in which the short fibers of the first layer and the third layer are entangled may be on both sides or one side. When hanging from one side, for example, the implantation shape of the needle can be changed to partially entangle. That is, when it is desired to eliminate stretchability only in the machine direction, the object can also be achieved by strongly entangled in a ridge shape along the machine direction. Anisotropy in stretchability has the advantage of being easy to handle during processing. Also, increasing the entanglement of the short fiber web increases the mechanical strength and makes the texture harder,
The thickness can be reduced, but the elasticity is reduced, so it must be appropriately selected depending on the purpose of the product.

い。The stretchable nonwoven fabric of the present invention, in which the fourth adhesive layer of the present invention has stretchability and has both stretchability and adhesiveness, can be adjusted by adjusting the degree of entanglement between the short fiber web and the elastomer nonwoven fabric. You can adjust the elasticity of the short fiber web. Further, regarding the adhesiveness between the adhesive layer and the short fiber web, the viscosity of the adhesive and the affinity with the short fibers are important. Further, a poultice or the like may be contained in the adhesive layer, and the poultice layer may be laminated. A polyvinyl acetate-based or acrylic-based emulsion is often used as the main component of the adhesive. The adhesive may be applied by a commonly used coating method using a doctor knife, but is not limited thereto.
