ABSTRACT:
A fibrous article having a suede-like surface is composed of numerous staple fiber bundle units mutually entangled with one another in a three-dimensional configuration. Each staple fiber bundle unit comprises a plurality of flexible and relatively movable synthetic organic ultrafine fibers having a substantially round cross-sectional profile, substantially the same fiber length, and lying axially along the longitudinal axis of the staple fiber bundle unit. Elastic bonding material is disposed around and spaced axially along the ultrafine fiber bundle units joining together adjacent ones of the ultrafine fiber bundle units at locations where they intersect with one another to jointly hold the entangled ultrafine fiber bundle units in their three-dimensional configuration while permitting slight relative longitudinal movement between the individual ultrafine fibers within each ultrafine fiber bundle unit. The ultrafine fibers located on at least one surface of the fibrous article have raised ends which are spaced-apart from each other and provide the fibrous article with good handling, touch, softness and excellent durability approaching that of natural leather.
