Polyester combined-filament yarn and woven or knitted fabric comprising it
Abstract:
A polyester combined-filament yarn having an excellent stretch property and a bathochromic effect, as well as uniformity of apparent dyed color density, comprises two different multifilament components (A) and (B), wherein the multifilament component (A) comprises polyester filaments composed of polyethylene terephthalate (PET) polymer, a metal-containing phosphorus compound (a) and an alkaline earth metal compound (b), and a conjugate multifilament component (B) comprises side-by-side or eccentric core-sheath conjugate polyester filaments composed of two mutually different polyester resins (at least one of which is polytrimethylene terephthalate resin), the mass ratio (A)/(B) of components (A) and (B) is in the range of 80/20 to 50/50. Woven or knitted fabrics comprising the combined-filament yarn are useful for women's and men's fashion apparel and black formals.
