Abstract

The invention discloses a P-based polyester fire-retardant fiber which comprises a fiber body containing polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate or cation-modified polyethylene terephthalate. The fiber body further contains a P-based fire retardant selected from 2-carboxyethylphenyl phosphoric acid, 2-carboxyethyl methylphosphonate or 2-carboxyethyl methylphosphoric acid. The production process of the fiber comprises mixing polyesters for forming the fiber body with the P-based fire retardant, performing melt-spinning to obtain fire-retardant fiber precursor, subjecting to winding, stretching and netting processes to make fire-retardant polyester long filament (that is P-based polyester fire-retardant fiber). The inventive fire-retardant fiber has the similar physical property to the common polyester fiber and is superior in good spinning property and excellent fire-retarding effect.

Description

Technical field: [0001] The invention relates to a flame-retardant fiber and a manufacturing method thereof. Background technique: [0002] Polyester fiber (that is, polyester) has the properties of high strength, good elasticity, strong wrinkle resistance, stable size, good wear resistance, stable chemical properties, easy to wash and quick dry, excellent heat resistance and weather resistance. Therefore, it is very popular both for civil and industrial use, and it is an ideal textile material. Polyester fibers are flammable fibers that are meltable. With the expansion of its application fields, in some special occasions, such as aviation, entertainment venues, home decoration materials or protective clothing required by some special industries, it is required To meet certain flame retardant requirements, otherwise it will greatly increase the unsafety of fire. Not only that, these polymers also melt and drip when burned or at high temperature, thus limiting their use in ...
