Abstract

The invention relates to a cool flame-retardant recycled polyester filament fiber and a production method thereof. The filament fiber is of a skin-core structure, a skin layer is obtained by melt spinning of cool master batch and a recycled polyester chip, and the addition amount of the cool master batch is 5wt%-10wt%; a core layer is obtained by melt spinning of flame-retardant master batch and a recycled polyester chip, and the addition amount of the flame-retardant master batch is 20wt%-30wt%; the cool master batch is obtained by blending granulation of cool powder and a recycled polyester chip in the mass ratio of (15%-25%) to (85%-75%); the cool powder is obtained by mixing of flaky jade, zinc oxide and titanium dioxide in the mass ratio of (50%-60%) to (10%-20%) to (40%-20%); the flame-retardant master batch is obtained by blending granulation of a flame retardant and a recycled polyester chip in the mass ratio of (25%-35%) to (75%-65%); the flame retardant is one or more of melamine, melamine cyanurate, triphenyl phosphate and polysulfonyldiphenylene phenyl phosphonate. The cool flame-retardant recycled polyester filament fiber has a cool property and a flame-retardant property and the spinnability and the functionality of the fiber are guaranteed at the same time.

Description

technical field [0001] The invention relates to a polyester filament fiber, in particular to a flame-retardant cool regenerated polyester filament fiber and a production method thereof, belonging to the technical field of synthetic fiber production and modification. Background technique [0002] The shortage of petroleum resources and environmental pollution have promoted the development of non-petroleum-based materials, among which recycled materials are an important development direction. The recycled polyester fiber has passed the authoritative certification of the Taiwan Environmental Protection Agency, the US SCS Environmental Protection Agency, the European Oeko-Tex Standard 100 ecological environmental protection certification and the international GRS recycling standard, and the international recognition is very high. However, the limiting oxygen index of pure regenerated polyester filament fiber is about 20%, which is a flammable fiber, so it is necessary to carry o...
