The invention relates to webs or batts including polytrimethylene
terephthalate crimped staple fibers and fiberfill products comprising such
webs and batts, as well as the processes of making the staple fibers,
webs, batts and fiberfill products. According to the preferred process of
making a web or batt, polytrimethylene terephthalate staple fibers,
containing polytrimethylene terephthalate is melt spun at a temperature of
245-285.degree. C. into filaments. The filaments are quenched, drawn and
mechanically crimped to a crimp level of 8-30 crimps per inch (3-12
crimps/cm). The crimped filaments are relaxed at a temperature of
50-130.degree. C. and then cut into staple fibers having a length of about
0.2-6 inches (about 0.5-about 15 cm). A web is formed by garnetting or
carding the staple fibers and is optionally cross-lapped to form a batt. A
fiberfill product is prepared with the web or batt.
