Kern für absorbierende hygienische Produkte

摘要

A core component (4) for use in a fluid-absorbing article, such as a diaper (2), incontinence pad, catamenial device or the like is described, which core component (4) has a plurality of core zones comprising a zone of vulnerability (a) positioned in said core component for maximum potential exposure to wetting, and at least one additional core zone (b,c) arranged in an area of reduced potential exposure to initial wetting and in direct or indirect quid receivable relation from the zone of vulnerability. The zone of vulnerability has a wadding component comprising synthetic fiber of filament and has a greater average pore size than the average pore size of the wadding component in the at least one additional core zone. When two or more additional core zones are used, the average fractional value of fiber volume-to-fiber surface area and the average pore size within the wadding components of the additional core zones decrease in value from zone to zone with increased distance from the zone of vulnerability (a) and with reduced risk of initial wetting. The zone of vulnerability may be further characterized by having a greater average liquid-solid contact angle than the average liquid-solid contact angle in the additional core zones. A quid absorbing article and a method for increasing quid receptivity, quid storage efficiency, and reduced rewet characteristics utilizing the core component of the invention are also described.
