Oriented microfibers and processes for making them are disclosed, together with blends of such microfibers with other fibers such as crimped staple fibers and non-oriented microfibers.

Oriented melt-blown fibers, processes for making such fibers and webs

A method for preparing melt-blown microfibers comprising extruding fiber-forming material through the orifices of a die into a high-velocity gaseous stream where the extruded material is rapidly attenuated into fibers, directing the attenuated fibers into a first open end of a tubular chamber disposed near the die and extending in a direction parallel to the path of the attenuated fibers as they leave the die, introducing air into the tubular chamber at a velocity sufficient to maintain the fibers under tension during travel through the chamber, and collecting the fibers after they leave the tubular chamber.
