Abstract:
1. Nonwoven comprising three separate and distinct fibers: thermoplastic fibers with a fusion temperature T m (th), bonding fibers 1 with a fusion temperature T m (1), and bonding fibers 2 with a fusion temperature T m (2), wherein for T the nonwoven contains the bonding fibers as a solidified melt; the thermoplastic fibers, the bonding fibers 1, and the bonding fibers 2 are mixed to create a random laid layer; in each volume element of the random laid layer, a ratio of a weight of the thermoplastic fibers w(th) to a weight of the bonding fibers 1 w(1) to a weight of the bonding fibers 2 w(2), is about the same; and the thermoplastic fibers are monofilaments, multifilaments, or mixtures thereof.
