| titleOfInvention | Preparation method of flame-retardant polyester fiber |
| abstract | The invention provides a preparation method of flame-retardant polyester fiber, which comprises the following steps: firstly, constructing metal oxide with ultra-small particle size, uniform and stable dispersion and capable of catalyzing polyester polycondensation reaction on a micron-sized template to generate a micro-nano material; secondly, introducing the micro-nano material into a polyester polymerization system, and introducing alkyl phosphinic acid metal salt to prepare flame-retardant resin: and finally, obtaining the flame-retardant polyester fiber by a melt spinning method, wherein the spinning speed is 800-4500 m/min. The micro-nano material realizes the dual functions of catalytic polycondensation and synergistic flame retardance, effectively improves the flame retardance of the polyester fiber, enlarges the application range of the polyester fiber, and is used for improving the production efficiency of the flame-retardant polyester fiber in industrial production. |
