Abstract:
The present invention relates to a bonded nonwoven having extensive fibers for use in articles such as diapers and other hygienic articles, wipes, interlinings and other articles requiring some degree of elasticity. Specifically it relates to bicomponent fibers where one component is an elastic thermoplastic and another component employed as a binder having a lower melting point than the elastic component. On bonding the binder melts to form bonding points exposing the elastic core. The present invention contemplates a bonded nonwoven article or a component thereof, comprising a blend of extensible bicomponent fibers, an absorbent, and optionally low melt binder fibers, or synthetic fibers, or both. The present invention also contemplates a method of producing a nonwoven by mixing the fibers described above, either by the dry laid or wet laid process, and heating the mixture to bond the fibers into a nonwoven article or a component thereof.
