Conjugate filaments

摘要

Conjugate filaments which exhibit a high degree of spontaneous crimp and good modulus are described. The filaments comprise at least 2 components, one of which being a blend of polypropylene with 5 to about 50% of certain low molecular weight hard resins derived from hydrocarbons having at least 4 carbon atoms or rosin derivatives and another component being polypropylene or a blend of polypropylene and a different amount of the hard resin or rosin derivative.
