Definitions

  • This invention relates to ultra low denier, rather long processable staple fibers. More particularly, this invention relates to synthetic staple fibers, which have a denier per filament of less than 1.5 and a length in inches that is numerically greater than its size in denier per filament, that are especially adapted for processing using a cotton system.
  • the bending force (P of the fiber will equal 0.158 gram. This fiber will not process satisfactorily on a cotton system. However, by raising the denier per filament to 1.5, the same 40 gram per denier staple fibers will have a bending force of 0.186 gram and the fibers will process properly in a cotton system. However, as will be appreciated, the staple fibers are now relatively larger (1.5 denier per filament or greater) and are not the size fibers (less than 1.5 denier per filament) desired.
  • the drafting condition is also the same as Example IV except that a two stage draw of 3:1 in hot water and 1.36:1 in steam is used and the total denier of the yarn is 600,000.
  • the yarn is heatset for 20 seconds at constant length in a hot air dryer at 220 C.
  • the staple fibers will have the following properties:
  • a drawn polyester textile fiber in staple form which can be processed using a cotton system, said fiber having a denier per filament of less than 1.5 a length in inches that is numerically greater than its size in denier per filament, an ultimate tenacity of at least 5.2 grams per denier With a tenacity of at least 4 grams per denier at 10 percent elongation, and said fiber having a bending force of at least 0.175 gram calculated by M I 20d* where:
