An object of the present invention is to provide a nonwoven fabric that makes it difficult to diffuse liquid in a plane direction and can absorb and transmit liquid in a spot manner, that is, a nonwoven fabric excellent in so-called spot absorbability. The nonwoven fabric according to the present invention is formed by mixing an artificial protein fiber and a hydrophobic synthetic fiber.

There is described a nonwoven material comprising a multilayered stack, the multilayered stack comprising discrete interconnected layers, each of the layers, which may be the same or different, comprising a composite fibre of from about 80 to 100% w/w leaf or stem fibre and from about 1 to 20% w/w of a polymer, wherein the polymer is fusible at a temperature of about 180° C. or less. There is also described a novel method of enzyme degumming leaf and/or stem fibres.
