ABSTRACT:
Composite of polyamide layer solvent bonded to cellulosic substrate is formed by solution electrospinning deposit of polyamide on cellulosic substrate with the solution subjected to electrospinning containing as solvent for polyamide one that swells cellulosic fibers on contact therewith and/or by depositing very long polyamide fibers of low average diameter.
