High-strength non-woven fabric

High-strength non-woven fabric laminated non-woven fabric, which has thermoplastic synthetic long fibers with a fiber diameter of 7-20 μm as upper and lower layers, and thermoplastic synthetic fine fibers with a fiber diameter of less than 5 μm as an intermediate layer, and each layer is integrated by pressure bonding. It is characterized in that it has a structure in which fine fibers enter at least one side of the long fiber layer with an entry index of 0.36 or more, and the long fibers are combined, embedded, or interwoven, and the laminated nonwoven fabric has a weight per unit area of ​​10 to 250 g / m2 or less, the bulk density is 0.20g / cm3 or more. The spunbonded laminated nonwoven fabric of the present invention has durability due to its formation of a fine fiber layer with a nonwoven structure, has various filtering and blocking functions, and its tensile strength is far superior to that of spunbonded nonwoven fabric .
[Claims] High-strength non-woven fabric, which has a thermoplastic synthetic long fiber layer with a fiber diameter of 7-20 μm as upper and lower layers, and at least one layer of thermoplastic synthetic fine fibers with a fiber diameter of 5 μm or less as an intermediate layer, which is pressed by Forming an integrated laminated nonwoven fabric, characterized in that a part of the fine fibers constituting the intermediate layer enters at least one side of the long fiber layer with an entry index of 0.36 or more, and the long fibers are combined or embedded or interwoven For mixed structure layers, the weight per unit area of ​​the laminated non-woven fabric is 10-250 g / m2, and the bulk density is 0.20 g / cm3 or more.
