POLYOLEFIN FIBER ROLL AND METHOD OF MAKING THE SAME

Polyolefin Fiber Roll and Method of Making the Same Acid- and caustic- resistant rolls are prepared by forming a nonwoven web of randomly laid entangled polyolefin fibers, stacking a multiplicity of segments of the web into a pile, compacting the pile under a compaction force equivalent to a room te...

Beschreibung
Zusammenfassung:	Polyolefin Fiber Roll and Method of Making the Same Acid- and caustic- resistant rolls are prepared by forming a nonwoven web of randomly laid entangled polyolefin fibers, stacking a multiplicity of segments of the web into a pile, compacting the pile under a compaction force equivalent to a room temperature compaction force of about 20 x 105 to 55 x 105 Pa, restraining the pile on its compacted configuration, and, if needed, dressing the sides of the compacted pile to form a smooth cylindrical surface. The preferred polyolefin fibers are formed of polyethylene, polypropylene or polybutylene.
