Fiber blending system

A method of forming a mat of cellulosic fibers and synthetic fibers, comprising the steps of:

• fiberizing cellulosic material into cellulosic fibers;
• injecting synthetic fibers into the cellulosic fibers;
• blending the cellulosic fibers with the synthetic fibers to form a fiber blend;
• dispersing the fiber blend through a fiber disperser having apertures to provide a dispersed blend;
• and
• collecting the dispersed blend as a mat on a fiber collector to provide a mat comprising pills of balled-up cellulosic and synthetic fibers wherein portions of the fibers of the pills extend in an upward direction relative to the plane of the mat;
• wherein the fiberizing and blending steps occur simultaneously in a blending and fiberizing chamber.

A method of forming a mat of cellulosic fibers and synthetic fibers, comprising the steps of:

• fiberizing cellulosic material into cellulosic fibers;
• dispersing the fiberized cellulosic fibers through a fiber disperser having apertures to provide dispersed cellulosic fibers;
• injecting a metered amount of synthetic fibers into the dispersed cellulosic fibers to blend the cellulosic fibers with the metered amount of synthetic fibers to form a fiber blend;
• and
• collecting the fiber blend as a mat on a fiber collector to provide a mat comprising pills of balled-up cellulosic and synthetic fibers wherein portions of the fibers of the pills extend in an upward direction relative to the plane of the mat.
