An absorbent article having a distribution member comprising non-biopersistent inorganic vitreous microfibers. The microfibers have an average effective diameter between about 0.1 micron and about 6 microns and are arranged in a fibrous assembly having a basis weight between about 40 g/m2 and about 350 g/m2 and a density between about 0.04 g/m3 and about 0.25 g/m3. In preferred embodiments, the fibrous assembly can vertically wick a 0.9% saline solution to a height of 5 cm in less than about 5 minutes.

A burn through resistant nonwoven mat and cover film composite for use in a thermal and/or acoustical insulation blanket system, are, preferably, made up of non- respirable and/or biosoluble base fibers and capable of retaining their integrity and dimensional stability during 4 minutes of exposure to a fluctuating high pressure flame front at a temperature of 1100°C. Examples of non-respirable base fibers which make up the nonwoven mat are quartz fibers; aluminosilicate, aluminoborosilicate or alumina ceramic oxide fibers; partially oxidized pitch based fibers; and partially oxidized polyacrylonitrile fibers having mean diameters greater than 6 microns. Examples of biosoluble fibers are biosoluble glass fibers. Preferably, the nonwoven mats also include a lubricant sizing with a water repellent additive.

Glass composition for ultrafine fiber formation

Glass compositions suitable for pot and marble fiberization display excellent chemical resistance to both acids and moisture while being highly biosoluble at the same time. The glass compositions are characterized by ratios of components which are reflective of acid resistance, biosolubility, and moisture resistance. Preferred glasses have a difference between HTV (10 3 poise) and liquidus greater than 500° F., and a biodissolution greater than about 350 ng/cm 2 /hr.

An insulation product especially suited for use as an aircraft insulation includes a blanket of randomly oriented entangled glass fibers bonded together by a thermosetting binder and having a mean diameter of about 1+/−0.25 microns. The blanket has a density between about 0.25 and about 1.5 pounds per cubic foot and a thickness between about 0.35 inches and about 2.0 inches. The blanket, exclusive of anything else, has an average machine direction tensile strength of at least 0.6 pounds/inch of blanket width and an average cross machine direction tensile strength of at least 0.3 pounds/inch of blanket length; a transverse airflow resistance between about 300 Rayls and about 1800 Rayls; and a thermal conductivity equal to or less than about 0.32 BTU-in/hr-ft 2 -° F. The glass fibers of the blanket have a biodissolution rate in excess of 150 ng/cm 2 /hr.
