Abstract

The invention relates to a manufacturing method of negative oxygen ion flame-retardant polyester BCF (bulk continuous filament) yarns. The manufacturing method comprises the following steps: performing mixing, roasting, dispersion and plasma treatment on three nano-scale fibers, namely basic magnesium sulfate whiskers, basic magnesium chloride whiskers and magnesium salt whiskers; then performing filtration, drying and other pretreatment; performing stirring and dispersion on the whiskers after pretreatment and a flame-retardant element material, namely aluminum oxide, a red phosphorus flame retardant, barium stearate, nano-scale tourmaline composite powder and a PP-g-MAH (maleic anhydride grafted polypropylene) compatibilizer in a mixing machine to get a flame-retardant whisker blend; preparing negative oxygen ion flame-retardant polyester from the flame-retardant whisker blend through a copolyester or blending method; and preparing the negative oxygen ion flame-retardant polyester BCF yarn through a composite spinning technology.

Description

technical field [0001] The present invention relates to a method for manufacturing negative oxygen ion flame-retardant polyester BCF yarn. The negative oxygen ion flame-retardant polyester BCF yarn includes polyester (PET), composite tourmaline powder, basic magnesium sulfate whisker, A magnesium salt whisker, a basic magnesium chloride whisker, a red phosphorus flame retardant, and aluminum oxide belong to the technical field of textile fiber manufacturing. Background technique [0002] Polyester fibers are made from polyethylene terephthalate, and the trade name is polyester. It is the largest variety of synthetic fibers at present. Due to the high rigidity of the fiber macromolecular chain, high elastic modulus, the fiber is not easily deformed, the processed fabric does not wrinkle after washing, can not be ironed, is firm and scratchable, and is easy to wash and dry. It also has good heat resistance, cold resistance, sun resistance and abrasion resistance, and is an i...
