The present invention discloses and claims an absorbent article which utilizes an absorbent portion that includes superabsorbent yarn as part of the absorbent portion, such that liquid is wicked to the perimeter or select regions of the absorbent portion, or the perimeter of the absorbent article itself, taking full advantage of either the depth, width, length or combination of dimensions of the absorbent portion, or absorbent article. The superabsorbent yarn can be one or more of several types, including encapsulated yarn, multilayered encapsulated yarn, coated yarn and sliver-formed yarn as long as such yarn includes at least two components, those being a superabsorbent polymer and a second material which promotes distribution of liquid along the yarn length. In alternatives of the invention, such absorbent article utilizing the superabsorbent yarn provides passive visual signals to consumers, of article saturation levels prior to leakage The present invention discloses and claims an absorbent article which utilizes an absorbent portion that includes superabsorbent yarn as part of the absorbent portion, such that liquid is wicked to the perimeter or select regions of the absorbent portion, or the perimeter of the absorbent article itself, taking full advantage of either the depth, width, length or combination of dimensions of the absorbent portion, or absorbent article.

In alternatives of the invention, such absorbent article utilizing the superabsorbent yarn provides passive visual signals to consumers, of article saturation levels prior to leakage Technologies related to contextual use and expiration of digital content are generally described. In some examples, a receiving device may connect with a sponsoring device having the digital content. A relationship property defines a relationship context between the receiving device and the sponsoring device. The receiving device may receive the digital content from the sponsoring device and use the digital content so long as allowed, as determined with reference to the relationship property. La presente invención describe y reivindica artículo absorbente que utiliza una porción absorbente incluye hilado superabsorbente como parte de la porción absorbente, de manera que el líquido se absorbe al perímetro a las regiones seleccionadas de la porción absorbente, o perímetro del artículo absorbente en sí mismo, tomando ventaja de la profundidad, ancho, longitud o combinaciones las dimensiones de la porción absorbente, o del artículo absorbente. El hilado superabsorbente puede ser de uno o de varios tipos, que incluyen hilado encapsulado, hilado encapsulado multicapa, hilado recubierto y hilado formado mechas siempre y cuando tal hilado incluya al menos componentes, que son un polímero superabsorbente y un segundo material que promueve la distribución de líquidos a lo largo de la longitud del hilado. En alternativas de la invención, tal artículo absorbente que utiliza el hilado superabsorbente proporciona señales visuales pasivas a los consumidores, los niveles de saturación del artículo antes de la fuga.
