How to judge the quality of fire-retardant fabrics
Abstract: Fire-resistant and flame-retardant fabric is a special fabric that must pass relevant test reports and meet the corresponding flame-retardant standards. Flame-retardant fabrics are not inflammable. After special processing, they can prevent the spread of flames and automatically extinguish themselves within a certain period of time, thereby reducing property losses and ensuring life safety. Flame retardant fabrics are widely used and play an important role in life and work. Flame retardant performance can be judged by the burning speed of the fabric. Contact the flame for a certain period of time according to the prescribed method, then remove the flame, and measure the time the fabric continues to burn with flame and without flame, and the time the fabric is burned.
Fire retardant fabric is a special fabric that must pass relevant test reports and meet the corresponding flame retardant standards.
Flame-retardant fabrics are not inflammable. After special processing, they can prevent the spread of flames and automatically extinguish them within a certain period of time, thereby reducing property losses and ensuring life safety. Flame retardant fabrics are widely used and play an important role in life and work.
The flame retardant performance can be judged by the burning speed of the fabric. Contact the flame for a certain period of time according to the prescribed method, and then remove the flame to measure the time the fabric continues to burn with flame or without flame, as well as the degree of damage to the fabric; at the same time, if the flame retardant performance is good, there is no harm to the human body and the environment. Hazardous substances indicate that the quality of the flame retardant cloth is better.
Extinguishing immediately after leaving the fire depends on the temperature and air flow (oxygen) of the fire at that time, as well as the length of time in this high temperature environment. If the oxygen index of textile materials is above 21% (the oxygen concentration in natural air is 21%), the textile product is self-extinguishing. According to the size of the extreme oxygen index, fabrics are usually divided into flammable (LOI less than 20%), combustible (LOI equal to 20%–26%), flame-retardant (LOI equal to 26%–34%) and non-combustible (LOI> 35%) four levels.
The shorter the flame burning time and the flameless burning time, and the lower the degree of damage, the better the flame retardant performance of the fabric; vice versa; , it means that the flame retardant performance of the fabric is poor.
