From the manufacturer:
Brief History of Durable FR Cotton Finishing
Technology
There are several different technologies available to make cotton fabrics
flame resistant, starting with the most basic “topical” non-durable applications
that can be removed in a single laundering and progressing up
to engineered fabrics that are flame resistant for the life of the garment.
The durable FR “ammonia cure” finishing technology was developed over
three decades ago. Westex’s own first-generation ammonia cure product,
Proban®/ FR-7A® is only guaranteed to retain its FR characteristics for 25
industrial or 50 home launderings and is an example of this type of “out-ofthe-
box” ammonia cure technology.
Other FR cotton finishing technologies, such as heat cure systems that
utilize conventional textile finishing equipment to apply flame retardant
chemicals, are generally not recommended for use in protective clothing.
These finishes typically require special care procedures when washed by
industrial laundries and some have “shelf life” issues; consequently, they
only have a minute share of the protective clothing market.
