To provide an economical method of less environmental loading for producing a nonwoven fabric for laminates, consisting mainly of p-aramid staple fibers by utilizing broke formed during the production process or defective nonwoven fabrics after the production process.
This method for producing the nonwoven fabric for laminates comprises a wet papermaking from a stock slurry consisting mainly of p-aramid staple fibers; wherein broke formed during the papermaking operation is disaggregated to make a regenerated slurry, which is mixed into the stock slurry; alternatively, recovered nonwoven fabrics or broke consisting mainly of p-aramid staple fibers and having a breaking length after immersed in distilled water for 5 min of ≤4 km are put into water and disaggregated into a regenerated slurry, which is mixed into the stock slurry.
