Classification of Flame Retardant Fabrics According to Flame Retardant Effect
Flame retardant fabrics are divided into fiber flame retardant fabrics and finishing flame retardant fabrics. The finishing flame retardant fabrics are further divided into disposable flame retardant fabrics and durable flame retardant fabrics.
Fiber flame retardant fabric, also known as permanent flame retardant fabric, is the work done in the early stage of the whole fabricting process. It is mainly made of woven fabrics made of flame retardant fibers, and its flame retardant effect is permanent. The flame retardant fabric can be curled and carbonized in case of fire, and extinguished when the fire source leaves. It does not melt black smoke, and does not cause secondary fire. It is usually used for flame retardant fabrics.
The disposable flame retardant fabric is a common fabric that has been treated with a flame retardant in the subsequent dyeing and finishing. The biggest disadvantage is that the flame retardant effect will disappear or have a significant decline after washing once, and the application is generally less in some washing times. Items such as hotel curtains.
Durable flame retardant fabrics are usually produced using a prolubenzene or CP process, and the flame retardant used is a durable finishing flame retardant for cotton fibers and their blended fabrics. The main feature of this flame retardant fabric is that after the finishing of the flame retardant, the fabric can have a good flame retardant effect within 50 times of washing.
The initial flame retardant properties of these three flame retardant fabrics are not much different, but the flame retardant properties of the disposable flame retardant fabrics will completely disappear after washing.
