Abstract:

An improved nonwoven web composite is formed by combining bicomponent thermoplastic filaments having adhesive properties with a component selected from other fibers and particles. The bicomponent filaments include distinct regions of first and second incompatible polymers across a cross-section of individual filaments. After the bicomponent filaments are combined with the other fibers and/or particles, the adhesive properties of the bicomponent filaments result in a web or matrix of filaments having improved ability to entrap, ensnare and contain the other fibers and/or particles within the web or matrix. The nonwoven web composite is particularly useful for making absorbent articles, which require stability and optimum levels of absorbent fibers and/or particles.
