Abstract
A novel blown microfiber web having a network of compacted high-density regions and pillowed low-density regions exhibits a unique combination of low density and good tensile strength and integrity. Such a web may be collected on a perforated screen so that microfibers deposited on the land area of the screen form the compacted high-density regions, and microfibers deposited over the openings of the screen form the pillowed low-density regions.
