Abstract

Una composición termoplástica derretida-extruíble, segregable de superficie está provista la cual incluye (A) un copolímero de bloque de polipropileno-polietileno termoplástico en el cual los bloque de polietileno constituyen desde 1 a alrededor de 10 por peso del copolímero y (B) un aditivo de triloxano poliéster definido un peso molecular de desde alrededor de 350 a alrededor de 1400, cuyo aditivo está presente en una cantidad de desde alrededor de 0.1 a alrededor de 5 por peso, basado sobre la cantidad del copolímero de bloque termoplástico. El uso del copolímero de bloque inesperadamente permite el uso de cantidades significativamente reducidas de l aditivo mientras que se proporcionan aún telas no tejidas las cuales son inmediatamente humedecibles y las cuales no se hacen significativamente menos humedecibles con el tiempo.
