ABSTRACT:
Bicomponent polyester filaments are disclosed, wherein the filaments are made of at least two different, substantially unmixed components, each present in an amount of at least 20% by weight of the total filament, one component being polyethylene terephthalate and the other component being polybutylene terephthalate which has been sparingly crosslinked with trimethylolpropane.
The bicomponent polyester filaments of the present invention have excellent physical properties and especially improved permanency of crimping. The filaments may be used to manufacture woven and knit materials, and are especially useful in the manufacture of hosiery, wherein the resulting hosiery articles have excellent wear properties.
