摘要： A non-woven fabric usable as a substratum sheet for artificial leather having a relatively high flexural rigidity is prepared by a process in hich fibrous bundles, each consisting of a plurality of extremely fine filaments or fibers having a denier of 0.005 to 0.5, is provided while allowing the filaments or fibers to spontaneously adhere to each other without using an adhesive, the fibrous bundles are massed into the form of sheet or web, and the sheet or web is then subjected to a non-woven fabric forming operation in which the fibrous bundles are entangled with each other.
