Technical Field

The invention relates to the field of preparation of flame-retardant fiber materials, in particular to a flame-retardant fiber material for fire fighting and a manufacturing method thereof.

Background

After a fire occurs, people need to perform actions of emergency rescue and disaster relief in order to reduce casualties and property loss of people as much as possible. However, fire fighting is dangerous, high temperature and flame can not only cause great harm to human body, but also hinder the rescue action of people, and the fire-fighting protective clothing for firefighters is professional protective equipment for protecting the body from flame and radiant heat during the fire-fighting of the firefighters, is the most commonly used equipment in the fire-fighting army at present, and is also personal protective equipment with the highest use frequency.

The fire-fighting protective clothing for firefighters is required to have flame retardance, heat insulation, lightness and thinness, thermal stability and the like, and generally comprises four layers, namely a flame-retardant outer layer, a waterproof breathable layer, a heat insulation layer and a comfortable inner layer, wherein the flame-retardant outer layer basically obtains flame retardance by doping a certain amount of flame retardant into fabric fibers. However, the flame retardant for the existing fabric has poor flame retardant effect, can still burn in a large area under high-temperature radiation heat energy, and has poor flame retardant and heat insulation properties.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a fire-fighting flame-retardant fiber material and a manufacturing method thereof, which are suitable for producing flame-retardant viscose fibers or flame-retardant synthetic fibers for fire-fighting protective clothing.
