Process to prepare synthetic fiber paper

A process of preparing a synthetic fiber paper having 50-80 parts, by weight, of poly(p-phenylene terephthal amide) fibers, 20-50 parts, by weight, of polyethylene glycol terephthalate fibers, and 0-50 parts, by weight, of powdered mica, comprising the following steps:

• treating the surface of a portion of said poly(p-phenylene terephthal amide) fibers to produce treated poly (p-phenylene terephthal amide) fibers;
• loosening and dissociating remaining of said poly (p-phenylene terephthal amide) fiber and said polyethylene glycol terephthalate fibers to produce loosened and dissociated fibers;
• compounding and pulping said treated poly (p-phenylene terephthal amide) fiber and said loosened and dissociated fibers to produce a pulp;
• and
• processing said pulp to produce said synthetic fiber paper wherein said polyethylene glycol terephthalate fibers have a melting point of about 255-260° C.
