Embodiment 1～5 and comparative example 1～3

[0049] A slurry of 8650 g of terephthalic acid (hereinafter referred to as "TPA") and 2700 g of ethylene glycol (hereinafter referred to as "EG") was subjected to an esterification reaction using a semi-batch process. The oligomer (which was prepared to have the same composition as in the slurry) was stirred in the esterification reactor while the temperature of the reactor was maintained at 250-260°C. After the slurry introduction was completed, the esterification reaction was continued for 30 minutes, thereby reaching an esterification reaction rate of 96.5%. The prepared oligomers are transferred to the polycondensation reactor. Use general formula 1 compound (wherein p is 1, R 1 and R 2 for CH 2 CH 2 OH) concentration of 65% by weight of the EG solution as a flame retardant. 1380 g of a flame retardant solution was introduced into the reactor, and then manganese acetate and phosphoric acid having concentrations of 44 ppm and 75 ppm in terms of manganese and phosphorus...

Embodiment 6

[0070] The false-twisted yarn of flame-retardant polyester and commercially available flame-retardant polyester false-twisted yarn SDM 150 / 144 (Hyosung, Korea) of the dope dyed flame-retardant polyester prepared in embodiment 1 were used as weft yarn and warp yarn to weave double-sided satin respectively, Its performance as a shade was then evaluated.

[0071] The flame retardancy of the shade was evaluated according to US Standard NFPA 701, and the shade passed the test. In addition, when the shading degree of the shade was evaluated in accordance with Japanese standard JIS L 1055, the result was 99.8%.

[0072] As described above, the dope-dyed flame-retardant polyester fiber according to the present invention has excellent flame retardancy, UV stability, and fastness. In particular, use of the fiber according to the present invention to prepare a blackout curtain or the like can provide excellent flame retardancy and light shielding properties at the same time.

Abstract

The present invention relates to dope dyed flame retardant polyester fibers, textile products therefrom, and the method of manufacturing thereof. The polyester fiber comprises flame retardant polyester polymers containing 500 - 50,000ppm of phosphorus-based flame retardant agent based on phosphorus atom, and 500 5,000ppm of carbon black based on said polyester polymers. The polyester fibers can provide excellent fastness and flame retardant characteristic without occurring hazardous, materials such as a dioxin during an incineration, and can be applied for fiber products such as blackout curtain having an effective light shielding.

Description

technical field [0001] The invention relates to a dope-dyed flame-retardant polyester fiber, a textile made therefrom and a manufacturing method thereof. Background technique [0002] Conventional methods of imparting flame retardancy to dope-dyed fibers can be largely classified into methods involving imparting flame retardancy through post-treatment and methods involving making fiber materials flame resistant, thereby imparting permanent flame retardancy to the material. [0003] Conventional methods of imparting flame retardancy using flame retardant post-treatments are commonly used for natural fibers such as cotton, and also for the production of flame retardant synthetic fibers. However, the method of imparting flame retardancy by post-treatment has a problem in durability, and an environmental problem due to waste water generated during the treatment. Therefore, the method is now widely used but will be phased out due to growing environmental concerns. [0004] In a...
