Title:
多成分の孔開き不織物
Document Type and Number:
Japanese Patent JP3744856
Kind Code:
B2
Abstract:
A nonwoven web is provided which can be readily converted to an apertured web by stretching. In its initial non-apertured state, the web comprises a plurality of multicomponent fibers comprising at least two thermoplastic polymer components arranged in at least first and second separate continuous structured domains. The polymer component of the first domain comprises polyethylene. Prior to stretch aperturing, the web has a peak elongation of at least 100 percent and is characterized by having a plurality of discrete, spaced-apart, frangible bond sites of polymer bonding the fibers to form a coherent extensible nonwoven web. The frangible bond sites are structured and arranged to readily rupture when subjected to tensile stress to form discrete, spaced-apart apertures in the nonwoven fabric. The web has a total energy absorption in at least one of the machine direction or the cross-machine direction of at least 50 gcm/cm2.
