Polyester staple fiber (PSF)/filament yarn (POY and PFY) for textile applications

The invention relates to a blended two component polymer system comprising Polytrimethylene Terephthalate (PPT) and a CoPolyester of Polyethylene Terephthalate (CoPET) with a PTT:CoPET composition ranging between 95: 5 and 5:95. The blended composition may be melt spun with circular and tetra lobal...

Beschreibung
Zusammenfassung:	The invention relates to a blended two component polymer system comprising Polytrimethylene Terephthalate (PPT) and a CoPolyester of Polyethylene Terephthalate (CoPET) with a PTT:CoPET composition ranging between 95: 5 and 5:95. The blended composition may be melt spun with circular and tetra lobal cross section spinnerettes for staple fibre and partially oriented yarn (POY) and the properties are compared with 100% PET polymer as well as 100% PTT polymer. The tetra channel fibre properties are superior when compared to the fibres produced from homopolymers as well as the bicomponent fibres particularly their moisture wicking characteristics and increased dyeability.
