    • The present invention relates to an X-ray sensitized yarn, a method for manufacturing the same, and an anti-forgery product using the same. The X-ray sensitized yarn of the present invention is manufactured by containing an X-ray absorbing material in an external core type composite fiber which is designed such that the total specific gravity of the external core type composite fiber prepared by melt complex spinning is one or higher and an external fiber is made of a hydrophilic polymeric resin. According to the X-ray sensitized yarn of the present invention, depending on the specific design of the external core type composite fiber, the percentage of the X-ray sensitized yarn added to a paper raw material which is sunk at the time of a paper making process can be increased, and the X-ray sensitized yarn can be easily blended with the paper raw material due to high dispersibility of the external fiber in the external core type composite fiber. The anti-forgery product using the X-ray sensitized yarn of the present invention facilitates authenticity identification on an X-ray, and thus can be usefully applied for anti-forgery of bills, vouchers, securities, and passports, or for preventing imitation of expensive luxury.

    • The present invention relates to a flame-retardant recycled polyester fiber with a low melting point and, in particular, to a sheath-core polyester composite fiber made by using a mixed spinning method after melting a sheath part and a core part separately. The sheath part is produced by using a first depolymerization process for depolymerizing waste polyester by mixing the waste polyester with ethylene glycol (EG) in a molar ration of 1.0 : 0.1 to 2.0; a second depolymerization for secondly depolymerizing bis-2-hydroxyethyl terephthalate produced in the first depolymerization process by mixing the bis-2-hydroxyethyl terephthalate with waste polyester, ethylene glycol (EG), isophthalic acid, diethylene glycol, ethylene glycol, polyethylene glycol, and a phosphorus-based flame retardant; and a drying process. The core part is produced by using a depolymerization process for mixing the bis-2-hydroxyethyl terephthalate (BHET) produced in the first depolymerization process with ethylene glycol (EG) and a phosphorus-based flame retardant; and a drying process.
