摘要:
There is provided a surge material for personal care products comprising a layered structure of at least one relatively high permeability layer on a top side toward a wearer and at least one relatively low permeability layer where the structure has a capillary tension range between about 1 and 5 cm with a differential capillary tension of at least about 1 cm from top to bottom. The surge material should have a high permeability layer with a permeability of at least 1000 Darcys and a low permeability layer with a permeability of less than 1000 Darcys. The surge material should also have a said high permeability layer which has a permeability of at least 250 Darcys greater than the low permeability layer. Such a layered structure should have a first insult run-off value of at most 30 ml from a 100 ml insult delivered at 20 ml/second. Such a surge material is useful in personal care products like diapers, training pants, absorbent underpants, adult incontinence products, feminine hygiene products and the like.
