ABSTRACT:
Nonwoven fabrics are described comprising a layered fabric having an inner layer of substantially thermoplastic material, for example fibers, disposed adjacent and thermally bonded to at least one outer layer or a pair of outer layers of textile length fibers by means of heat and pressure. The thermoplastic fibers in the inner layer have a lower melting point than any other fibers in the fabric. A nonwoven fabric constructed in this manner has qualities of; low levels of debris, high compressibility, low abrasiveness, and dimensional stability. These qualities are decidedly of use in many products, most particularly in computer diskettes, wherein a material must be used to wipe the magnetic disk within the computer diskette to keep it free of foreign particles, which may cause errors in the transfer of information onto or from the magnetic disk.
