Classification and standards of flame retardant fabrics
Classification and standards of flame retardant fabrics
At present, the main flame-retardant fabrics include: finishing flame-retardant fabrics, such as pure cotton, polyester cotton, etc.; intrinsic flame-retardant fabrics, such as aramid, acrylic cotton, DuPont Kevlar, Nomex, Australian PR97, etc.
Flame retardant fabrics are divided into two types: fiber flame retardant and post-finishing flame retardant. Post-finishing flame retardant is divided into two types: disposable flame retardant and durable flame retardant.
Fiber flame retardant, also called permanent flame retardant fabric, is mainly woven with flame retardant fibers. Its flame retardant effect is permanent and can generally be maintained for more than 50 times of washing, and still has a good flame retardant effect.
Durable flame retardant fabrics usually use the “PROBAN” production process. The flame retardant used is a durable finishing flame retardant used for cotton fibers and their blended fabrics. Its main feature is the use of this After the production and finishing of this kind of flame retardant, the fabric can have good flame retardant ability within 50 times of washing.
Disposable flame retardant fabrics are ordinary fabrics that have been treated with flame retardants in the later dyeing and finishing process. Their biggest disadvantage is that the flame retardant effect disappears or significantly declines after washing. Usually we apply it to some occasions where the number of washings is small, such as Hotel curtains, etc.
There is not much difference in the initial flame retardant properties of the three, but the flame retardant properties of the disposable flame retardant fabric completely disappear after washing.
The flame-retardant fabrics produced by Kunshan Yingjie Textile Import and Export Co., Ltd. include pure cotton, polyester cotton, chemical fiber and other materials. They have good flame-retardant effects. They will shrink and carbonize when exposed to fire. They will be extinguished as soon as the fire source is removed. It emits black smoke and will not cause secondary fires. The fabric performance meets the first-class requirements of the national standard GB8965-2009. Environmentally friendly, non-toxic, odorless, moisture-permeable, breathable, soft to the touch, widely used in military, firefighting, smelting, petrochemical and other industries.
