ABSTRACT:
Laminates with improved peel strength are obtained by point bonding thermoplastic layers wherein one of the layers comprises sheath/core bicomponent fibers or filaments wherein the density of the core component exceeds the density of the sheath component and both layers contain compatible components. Peel strengths of at least about 125% of those obtained without such bicomponent fibers or filaments are obtained. Laminates with films and other nonwovens also have a broad bonding window. They are useful for many nonwoven applications including barrier applications such as health care including surgical gowns and drapes, institutional garments, agricultural fabrics, recreational fabrics, and personal care product components.
