摘要： Nonwoven materials having at least one layer comprising high core bicomponent fibers are provided. The nonwoven materials can have multiple layers and are suitable for use in a variety of applications, including in absorbent products. Such nonwoven materials can be patterned to create a three-dimensional topography including indentations formed of valleys and ridges. The nonwoven materials can have improved resiliency and strength and can retain their structure under wetted conditions and after tension and compression. The nonwoven materials can further facilitate the transfer of the liquid through the nonwoven material for improved liquid distribution and can also have improved liquid retention properties.
