Absorbent article with heat activatable web

Abstract

Material webs suitable for use in conjunction with disposable absorbent articles are disclosed herein. The material webs comprise a melt additive that when subjected to thermal energy may be encouraged to bloom across the entirety of the web or in localized areas of the web where localized thermal energy is applied.

1 - 20 . (canceled) 
     
     
         21 . An absorbent article comprising:
 a topsheet;   a backsheet;   an absorbent core disposed between the topsheet and the backsheet; and   a material web forming a portion of the absorbent article, the material web having a first surface and an opposing second surface, and wherein the material web comprises a thermoplastic polymeric material and a melt additive homogeneously mixed with the thermoplastic polymeric material and melt additive bloom areas disposed on the first surface, and wherein the thermoplastic polymeric material and the melt additive are matched to discourage auto blooming of the melt additive at room temperature;   wherein the material web further comprises a plurality of apertures; and   wherein said melt additive bloom areas comprise a first portion surrounding said apertures and a second portion defined by melt lips of said apertures, wherein said first portion comprises a higher percentage of melt blooming than said second portion.   
     
     
         22 . The absorbent article of  claim 21 , wherein the material web forms a portion of the topsheet. 
     
     
         23 . The absorbent article of  claim 21 , wherein the melt additive bloom areas are more hydrophobic than the thermoplastic polymeric material as determined by the Scanning Electron Microscope (SEM) Method for determining contact angle on fibers. 
     
     
         24 . The absorbent article of  claim 21 , wherein the material web is a nonwoven material comprising a plurality of staple length fibers. 
     
     
         25 . The absorbent article of  claim 24 , wherein a first plurality of staple length fibers comprise the melt additive and a second plurality of staple length fibers do not comprise the melt additive of the first plurality of staple length fibers. 
     
     
         26 . The absorbent article according to  claim 21 , wherein the material web is a nonwoven material comprising continuous filaments. 
     
     
         27 . The absorbent article of  claim 21 , wherein a first migration coefficient of the melt additive bloom areas is at least two times a second migration coefficient of a non-activated area of the thermoplastic polymeric material. 
     
     
         28 . The absorbent article of  claim 21 , wherein the material web comprises the thermoplastic polymeric material, the melt additive, and an additive which influences crystallinity of the thermoplastic polymeric material, the additive being selected from at least one of a nucleating agent, branched polymers, or random co-polymers. 
     
     
         29 . The absorbent article of  claim 21 , wherein said melt additive bloom areas are in the form of a film, flakes, fibrils, or combinations thereof.
