<P>PROBLEM TO BE SOLVED: To provide a method for producing a creped laminated nonwoven fabric from any kind of fiber, regardless of the type of a constituent fiber of the nonwoven fabric. <P>SOLUTION: A stretchable net that does not have a stretchability in the machine direction and has a stretchability in the width direction is prepared. The stretchable net is composed of vertical monofilaments having no stretchability and horizontal monofilaments having stretchability, which are arranged in a lattice form. On both sides of the stretchable net, a staple fiber web produced by mixing, opening and accumulating cotton fibers and polyester staple fibers is laminated. And then a high-pressure liquid flow is applied from the staple fiber web side in order to mutually entangle the cotton fibers and the polyester staple fibers and, at the same time, entangle the cotton fibers and the polyester staple fibers with the stretchable net, providing an integrated laminated nonwoven fabric. After this, the laminated nonwoven fabric is widened in the width direction. Then, the stretchable net is shrunk by releasing the widening so that the width of the stretchable net returns to its original length. Thus, a creped laminated nonwoven fabric is obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
