The purpose of the present invention is to improve water drainage performance of a gas diffusion electrode including a carbon fiber nonwoven fabric. The present invention provides a gas diffusion electrode base material essentially consisting of a carbon fiber nonwoven fabric, wherein the carbon fiber nonwoven fabric has an in-plane basis weight pattern in which high basis weight regions having a relatively high basis weight and low basis weight regions having a relatively low basis weight are arranged, and the carbon fiber nonwoven fabric has on at least one surface an uneven pattern in which recesses and projections are arranged, the uneven pattern being formed independently of the basis weight pattern.

An apparatus for dry-manufacturing recycled leather comprises air-laid material; and recycled leather manufactured using the apparatus for dry-manufacturing recycled leather. The apparatus for dry-manufacturing recycled leather molds leather fibers and general fibers, which are mixed using air-laid material, and thus a conventional carding process is not required, and recycled leather manufactured thereby has a high tensile strength.

A sound-absorbing material nonwoven fabric includes: 30 to 80 mass % of short fibers A having a fineness of 0.4 to 0.9 dtex; and 20 to 70 mass % of short fibers B having a fineness of 1.1 to 20.0 dtex. A carding passage coefficient of the short fibers A calculated from equation (1) is in a range of 15 to 260. The equation (1) is carding passage coefficient=(fineness?strength??elongation percentage??number of crimps??crimping degree)/(fiber length).

The present disclosure relates to a hydroentangled composite fabric and a method of making such a hydroentangled composite fabric. In one embodiment, a method for making a hydroentangled composite fabric is disclosed. The method comprises forming a first web of nonwoven fibers using a first carding machine; forming a second web of nonwoven fibers using a second carding machine; combining the first web of nonwoven fibers and the second web of nonwoven fibers into a final web of nonwoven fibers; and entangling the final web of nonwoven fibers with a woven fabric using a plurality of water jets, wherein the water jets are applied at a pressure of 75 to 400 bars.
