Abstract
The invention discloses an environment-friendly flame-retardant polyester fiber. The fiber is prepared from, by mass, 80-85% of a polyester fiber body, 10-18% of phosphorus flame retardant and 2-5% of inorganic substances, wherein the phosphorus flame retardant and the inorganic substances are added into the polyester fiber body. The flame-retardant polyester fiber is prepared in the mode that the phosphorus flame retardant and the inorganic substances of the formula are added into the polyester fiber body by means of the melt spinning method. In this way, the phosphorus flame retardant and the inorganic substances in a reasonable formula ratio are added into the polyester fiber body, so that the LOI value of the prepared flame-retardant polyester fiber reaches 35% or above, and the polyester fiber has excellent flame retardancy and environmental friendliness and also has good abrasion resistance and soft hand feeling.
Description
Technical field
The present invention relates to fire resistance fibre field, particularly relate to a kind of environmental-protection flame-retardant polyester fiber.
Background technology
Along with increasing considerably of textile demand, textile the disaster hidden-trouble caused is consequently increased.Showing the result of the death by accident investigation caused by fire, the fire that textile causes holds pride of place.Therefore, for preventing the generation of fire, flame retardant textiles is increasingly subject to people's attention, and the research to fire resistance fibre also becomes the Important Problems that current textile is studied.
Combustible needs enough temperature and oxygen, burning to be difficult to degree can to pass through limited oxygen index (LOI) and characterize.Under normal circumstances, air oxygen concentration is 21%, therefore, as LOI ＞ 21%, i.e. showing that this material is difficult to burn in atmosphere, the LOI value of polyester fiber is generally 18%-20%, its fire resistance i.e. is poor, it is difficult to meet the use requirement of high reliability flame-retardant textile.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of environmental-protection flame-retardant polyester fiber, has anti-flammability and the feature of environmental protection of excellence, has good wearability and pleasant softness simultaneously.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of environmental-protection flame-retardant polyester fiber, the phosphorus flame retardant including polyester fiber main body and being added in described polyester fiber main body and inorganic matter, calculate by mass percentage, the content of described polyester fiber main body is 80%-85%, the content of described phosphorus flame retardant is 10%-18%, the content of described inorganic matter is 2%-5%, described fire-retardant polyester fibre is to use the phosphorus flame retardant of above-mentioned formulation material and inorganic matter to add in polyester fiber main body, then prepares through melt spinning method.
In a preferred embodiment of the present invention, described phosphorus flame retardant is 2-hydroxyethylbenzene phosphoric acid or 2-hydroxyethyl methyl phosphoric acid.
In a preferred embodiment of the present invention, described inorganic matter includes: silicon dioxide, aluminium hydroxide and magnesium hydroxide.
In a preferred embodiment of the present invention, the spinning temperature that described melt spinning method uses is 240-245 DEG C.
In a preferred embodiment of the present invention, the spinning speed that described melt spinning method uses is 3600-3800m/min.
The invention has the beneficial effects as follows: the present invention is by adding phosphorus flame retardant and the inorganic matter of rational formula amount in polyester fiber main body, the LOI value making the fire-retardant polyester fibre prepared reaches more than 35%, there is fire resistance and the feature of environmental protection of excellence, there is good wearability and pleasant softness simultaneously.
