▎ 摘　　要

NOVELTY - Flame-retardant low-melting polyester fiber comprises first polyester as first polyester matrix, and second polyester as second polyester matrix located on the surface of the first polyester matrix, halogen-free phosphorus flame retardants, and carbon materials dispersed in the first polyester matrix and the second polyester matrix. The melting point of the second polyester is less than the melting point of the first polyester. USE - Used as flame-retardant low-melting polyester fiber. ADVANTAGE - The flame-retardant low-melting polyester fiber has excellent flame-retardant performance, mechanical property and oxidation resistance property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of the flame-retardant low-melting polyester fiber.
