    • The present invention relates to a high tenacity, high modulus and low shrinkage lyocell multifilament yarn suitable for use in tire cords and MRG (mechanical rubber goods). The lyocell multifilament yarn is a cellulose-based fiber for industrial applications, which is produced by dissolving pulp having a degree of polymerization (DPW) of 700-2,000 and preferably 800-1,400, and a α-cellulose content of more than 90% and preferably more than 92%, in N-methylmorpholine N-oxide (NMMO) hydrate, at a pulp concentration of 5-15% by weight and preferably 8-13% by weight.The lyocell monofilament according to the present invention is characterized by the following stress-strain profile: (1) the lyocell monofilament analyzed after drying is elongated by less than 3.0% and has an initial modulus of 150-400 g/d, when it was subjected to an initial stress of 3.0 g/d; (2) it is elongated by 3.0-7.0% when it was subjected to a stress greater than the initial stress but smaller than 6.0 g/d; and (3) it is elongated from a tensile tenacity of at least 6.0 g/d until the yarn is broken.

    • Disclosed is a flame-retardant polyester polymer dyeable with a cationic dye, a method of producing the same, a copolyester fiber using the same, and fiber products using the copolyester fiber. In the method, after a dimethyl isophthalate component containing metal sulfonate of Formula 2 separately reacts with ethylene glycol so that an extent of the ester interchange reaction is 95% or more to synthesize bis(hydroxyethyl terephthalate) containing metal sulfonate of Formula 3, bis(hydroxyethyl terephthalate) is fed so that a content of bis(hydroxyethyl terephthalate) is 0.01-5 mol % based on a diacid component in a polymer in a course of producing polyester, a phosphorus-based flame retardant of Formula 1 is fed so that a content of a phosphorus atom is 500-40000 ppm based on the polymer, and the mixture is copolymerized. The polyester polymer is dyeable with cationic dye while having excellent flame retardancy, and can be melt-spun like other polymers capable of being melt-spun. The copolyester fiber using the polyester polymer is capable of being processed according to processes through which conventional polyester fibers are processed, and is dyeable with cationic dye while having excellent flame retardancy.
