Abstract

The invention relates to the field of polyester fibers, in particular to a processing method of melt direct spinning on-line adding flame-retardant and anti-dripping polyester fiber. The method comprises the following steps of 1, preparing a flame-retardant and anti-dripping agent; 2, carrying out a first esterification reaction; 3, carrying out a second esterification reaction; 4, carrying out condensation polymerization; and 5, preparing the flame-retardant and anti-dripping polyester fiber. The flame-retardant and anti-dripping agent formed by mixing decabromodiphenyl ethane, a phosphorus flame retardant and zinc borate according to a proper proportion is added into polyester fiber, so that the flame-retardant property of the polyester fiber is effectively improved, the overall performance of the polyester fiber is greatly improved, and the polyester fiber can be better applied to various fields; and in addition, the flame retardant formed by mixing the decabromodiphenyl ethane, the phosphorus flame retardant and the zinc borate as an environment-friendly and non-toxic novel flame retardant has good thermal stability and has good compatibility with polyester.

Description

technical field [0001] The invention relates to the field of polyester fibers, in particular to a processing method for adding flame-retardant and droplet-resistant polyester fibers on-line by melt direct spinning. Background technique [0002] Polyester fibers are widely used in clothing, daily necessities, industrial supplies and other fields due to their high strength, good elasticity, anti-wrinkle and heat resistance, and corrosion resistance. However, their limiting oxygen index is low and they are flammable materials. The phenomenon of molten droplets is serious during combustion. The dripping objects with flames will not only ignite the surrounding objects and cause secondary combustion, but also cause harm to the human body, bringing safety hazards to people's lives, lives and property, which greatly limits the The scope of application of polyester fiber, how to improve the flame retardancy of polyester fiber and ensure its own excellent characteristics to the greate...
