    摘要： A polymeric composition suitable for manufacturing heat sealable films or sheets comprising, polyethylene terephthalate (PET) to the extent of about 80% to 95% by mass of the total composition; a polymer additive for lowering the melting point of the composition selected from Polyethylene Naphthalate (PEN), Polytrimethylene Naphthalate (PTN), in-situ formed Polyethylene Naphthalate (PEN) and in situ formed Polytrimethylene Naphthalate (PTN) to the extent of about 20% to 5% by mass of the total composition; a nucleating agent to the extent of about 200 to 1500 ppm by mass of the composition; a polycondensation catalyst to the extent of about 30 to 300 ppm by mass of the composition; a clear fast reheat (CFRH) additive to the extent of about 10 to 30 ppm by mass of the composition; a color toner to the extent of about 0.75 to 25 ppm by mass of the composition; and a heat stabilizer to the extent of about 20 to 55 ppm by mass of the composition.

    摘要： 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 which is melt spun with circular and tera lobal cross section spinnerettes for staple fiber and partially oriented yarn (POY) and the properties are compared with 100% PET polymer as well as 100% PTT polymer whose tetra channel fiber properties are superior when compared to the fibers produced from homopolymers as well as the bicomponent fibers, particularly their moisture wicking characteristics and increased dyeability.
