WALZE AUS POLYOLEFINFASERN UND VERFAHREN ZU DEREN HERSTELLUNG. |
摘要 |
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 10<5> to 55 x 10<5> 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. |
