What is the characteristics of high-strength non-woven fabrics?
 
 
a laminated nonwoven fabric comprising a thermoplastic synthetic long fiber having a fiber diameter of 7 to 20 μm as an upper layer, and a thermoplastic synthetic fine fiber having a fiber diameter of 5 μm or less as an intermediate layer, wherein each layer is integrally formed by pressure bonding, and is characterized in that The fine fiber enters at least one side of the long fiber layer with an entry index of 0.36 or more, and a structure in which long fibers are bonded, embedded or interwoven, and the laminated nonwoven fabric has a basis weight of 10 to 250 g/m 2 or less, and a bulk density. It is 0.20 g/cm3 or more. The spunbonded laminated nonwoven fabric of the present invention has durability due to its formation of a microfiber layer of a non-woven structure, and has various filtration and blocking functions, and its tensile strength is far superior to that of a spunbonded nonwoven fabric. .
