According to the dictionary, Inherent means: “existing in something as a permanent, essential, or characteristic attribute”.
In terms of FR fabrics, the word ‘Inherent’ is generally applied to yarn, fabric or a finished garment that is deemed to offer permanent Flame Protection properties not affected by the washing process.
In reality, it is the yarns themselves that are ‘Inherent’ as the finished fabric (and therefore also the garment) always contains other yarns such as Cotton. Generic names for these Inherent yarns would be ‘Modacrylic’ or ‘Aramid’ and brand names would include ‘Nomex’, ‘Protal’, ‘Protex’ to name a few.
The amount of Inherent yarn in a fabric blend will vary according to the specification to which the finished fabric is certified.
