PURPOSE: To obtain a regenerated feedstock, and regenerated nonwoven fabric and regenerated interlaced nonwoven fabric each containing the feedstock by disaggregating interlaced webs through mechanical shear force, thereby trying to reduce garbage by reusing interlaced webs having been considered to be hard to recycle. CONSTITUTION: This regenerated feedstock is obtained by disaggregating interlaced webs where short fibers <=2000 in aspect ratio interlaced with one another. The 2nd and 3rd other objective regenerated nonwoven fabric and regenerated interlaced nonwoven fabric contain this regenerated feedstock, respectively. Specifically, the above regenerated webs are disaggregated in water by mechanical shear force to produce the regenerated feedstock in the form of a short fiber suspension; this suspension is, in turn, webbed by wet papermaking process to produce the regenerated nonwoven fabric; and, the above suspension is webbed by wet papermaking process and the resultant web is put on a porous substrate, and a relatively moving water jet is then applied on the web to effect interlacing the fibers, thus producing the regenerated interlaced nonwoven fabric. |
