MECHANICALLY CRIMPED FIBER TOW HAVING INCREASED BULK AND CRIMP TAKE-UP |
| 摘要 |
An improved fiber tow and process for forming the same is disclosed. The fiber tow may include a plurality of mechanically crimped fibers with a primary crimp having a saw tooth crimp shape. For fiber tows comprising fibers with denier per filament of greater than about 5, the plurality of mechanically crimped fibers have an average crimp take-up of greater than about 40%. For fiber tows comprising fibers with denier per filament of less than about 5, the plurality of mechanically crimped fibers have an average crimp take-up of greater than about 30%. |
