Title:
LAMINATED NONWOVEN STRUCTURE
Document Type and Number:
Japanese Patent JP3305453
Kind Code:
B2
Abstract:

PURPOSE: To obtain a laminated nonwoven structure suitable as a living related material by fixing the thermoplastic extremely fine fibers constituting a nonwoven fabric layer to the long fibers having slightly thick single fiber fineness constituting a nonwoven fabric layer in a molten state and fixing the natural fibers positioned on the boundary surface of a nonwoven fabric layer composed of natural fibers in the state embedded in the molten parts of the extremely fine fibers.
CONSTITUTION: A laminated nonwoven structure is formed by laminating a nonwoven fabric layer B composed of single fiber fineness of 1.0 denier or more on the single surface of a nonwoven fabric layer A composed of thermoplastic extremely fine fibers with single fiber fineness of 0.2 denier or less and subsequently laminating a nonwoven fabric layer C wherein natural fibers are mechanically entangled with each other on the other surface of the nonwoven fabric layer A. Herein, extremely fine fibers, long fibers and natural fibers form spotted fusion areas respectively. That is, the extremely fine fibers 1 of the nonwoven fabric layer A and the long fibers 2 of the nonwoven fabric layer B form molten parts to be fixed and the natural fibers 3 positioned on the boundary surface of the nonwoven fabric layers A, C are fixed in the state embedded in the molten parts of the extremely fine fibers and the respective nonwoven fabric layers A, B, C are integrated as a whole.
