摘要： Disclosed is a method for producing a polyethylene-2,5-furandicarboxylate (PEF) raw yarn which includes a drawing step wherein an undrawn yarn, obtained by melt-spinning of a PEF-containing resin composition, is drawn into a PEF raw yarn, wherein a draw ratio in the drawing step is greater than 6.0 times.

摘要： A polyester composition comprises poly(alkylene furandicarboxylate) and a color- stabilizing agent. The poly(alkylene furandicarboxylate) may be poly(ethylene 2,5- furandicarboxylate). Suitable examples of the color-stabilizing agent in such a composition include the compounds selected from the group consisting of a sterically hindered phenolic compound, a phosphonite compound, a phosphite and combinations thereof. In particular the color-stabilizing agent is a phosphite containing at least one tri-substituted phenyl moiety.

摘要： Disclosed is a PEF fiber for tire which includes a polyethylene-2,5-furandicarboxylate (PEF) raw yarn, wherein the PEF raw yarn is obtained by continuously drawing, without recovering, an undrawn yarn obtained by melt-spinning of a PEF-containing resin composition, and wherein the PEF raw yarn has a storage modulus of 1,300 MPa or more.

摘要： Disclosed is a method for producing a polyethylene-2,5-furandicarboxylate (PEF) raw yarn including a spinning/drawing process wherein an undrawn yarn, obtained by melt-spinning of a PEF-containing resin composition, is continuously drawn into a PEF raw yarn without being recovered and the PEF raw yarn is taken up, wherein the ratio of a rate (T) of taking up the PEF raw yarn to a rate (E) of extrusion of the resin composition into filaments during the melt-spinning (T/E) is 700 to 2,000.
