Permanent flame retardant fabric is a type of technical fabric that avoids fire propagation and its main feature is that this fire resistance, keeps unalterable over the years: nor with abrasion by the garment’s use or washes, its efficiency before fire is not altered…
There will be no washing out or wearing away of their inherent flame resistant properties, which helps make for a longer garment life cycle, value and peace of mind for the wearer.
We-Hai Huei supply and manufacture Nomex, Nomex IIIA, Kevlar and FR blending knitted fabric which are all permanent flame resistant fabric.
Inherently flame resistant, DuPont-Nomex offers supreme strength and heat performance. It does not melt, drip or support combustion in the air. A key factor in the protection provided by Nomex flame resistant fabric is its ability to carbonize and thicken when exposed to flame or heat. This typical reaction increases the protective barrier between the heat source and the skin to giving the wearer vital extra seconds of protection to escape and minimizes burn injury.
Kevlar is a heat-resistant para-aramid synthetic fiber from the DuPont and itself with a molecular structure of many inter-chain bonds that make Kevlar® incredibly strong. Kevlar's feature have stronger than steel, tensile strength, ballistic resistance cut & puncture resistance, heat resistance
The two types of flame retardant fibers or more are blended together to create fabrics that have a combination of properties to improve or adding its functionality and diversification, such as more strength & durable (Kevlar fiber), comfort (Lenzing viscose or cotton), competitiveness (Modacrylic). To provide more Applicability and choice- from FR Blending of flame resistant fabric.

Lenzing FR® has good resistance to sunlight and aging, fair resistance to abrasion, and poor resistance to mildew. NOMEX® has been blended with Lenzing FR® which produces a durable fabric with higher moisture regain than 100% aramid. These blends is including 20/80 blend of Nomex and Lenzing FR, and 60/40 of Nomex and Lenzing.More
