The detection of flame-retardant fabrics is a complex process and requires detection of many items. Today we mainly talk about the shrinkage, tear strength, carbon length, and burning of flame-retardant fabrics. Flame retardant fabrics smolder.
Shrinkage of flame-retardant clothing refers to the percentage of fabric shrinkage after washing or soaking in water. Test results to prove whether the garment has shrunk.
The tear strength of flame-retardant fabrics indicates the strength of the fabric. Stretch indicates the force required to break, and the morphological stability and elasticity of the fabric. The less likely it is to tear, the stronger the fabric is.
The carbon length of flame-retardant fabrics refers to the length of carbonization of the fabric after the fabric is ignited by an open flame for a certain period of time and the combustion is completely extinguished. Indicates the flame retardant properties of the fabric.
The burning of flame-retardant fabrics can be divided into many types, such as: sustainable burning, smoldering, and non-burning. So what is the sustainable burning of flame-retardant fabrics? The sustainable combustion of flame-retardant fabrics means that the burning material still continues to burn after it leaves the flame. In other words, a flame is produced during the combustion process.
Many people are not particularly clear about the concept of smoldering flame retardant fabrics. The smoldering of flame-retardant fabrics means that after the burning substance leaves the fire, it still continues to burn without flames, and causes the carbon length of the flame-retardant fabric to change. If there is no change in char length during flameless combustion, it is not smoldering.
