Question about fibers and yarns:
What kind of polypropylene yarn is suitable for braiding ropes and tapes? There are some kinds such as FDY (Fully Drawn Yarn), POY and FOY? Do they vary in cost dramatically? (Typically for braiding ropes, 600-900-1200 denier yarn is used, but I am not knowledgeable about the various kinds or the advantages. Any pointers? books? industry reports?
thanks!
