INFORMATION BULLETIN

AMTEXTMFLAME RESISTANT FABRICS

AMTEXTM

Flame Resistant Fabrics are treated with a phosphonium sulfate and

urea based precondensate. Once applied to the fabric, this chemical is cross-linked with ammonia and then oxidized with hydrogen peroxide to complete thereaction to form a polymer that becomes permanently polymerized within thefabric. The flame resistance of AMTEX

TMfabrics is durable for the life of the

garment when laundering is in accordance with the garment manufacturersinstructions.

The flame retardant used contains very low levels of formaldehyde. Theformaldehyde level in the fabrics prior to laundering will be less than 75 parts permillion (ppm) (0.0075%) when tested utilizing the Japanese Law 112 TestMethod. While a few individuals may show skin sensitivity to formaldehyde at

this level, the vast majority is unaffected.

All fabrics manufactured by Mount Vernon meet all of the restrictions andlimitations in the most recent version of the AAFA Restricted Substances List(RSL) as well as Appendix 4 of Oeko-Tex Standard 100 for Product Class II.This includes our ultra-low formaldehyde AMTEX

TMFR high performance fabrics

manufactured after June 2012. As this new development in ultra-lowformaldehyde FR fabrics comes on the heels of the already state-of-the-artchemistry for imparting flame resistance on cotton in order to meet ourcustomers (and end user's) strict performance criteria for these highperformance fabrics, we are excited to be able to offer an even better product.

Our FR chemistry will still be based on tetrakis hydroxymethyl phosphoniumsulfate (THPS), which is not listed on any of the published RSL's.

The formaldehyde present in AMTEXTM

Flame Resistant Fabrics is bound up inthe fabric and is not likely to become airborne. During fabric processing such ascutting and sewing, working conditions should be optimized through adequateventilation and climate control.

The Occupational Safety and Health Administration (OSHA) has established1000 ppm (0.1%) as the reporting threshold for formaldehyde. While the levelsin these fabrics are well below this, Mount Vernon reports the values as acourtesy to our customers. We believe that the ultra-low level of formaldehydepresent in AMTEX

TMFlame Resistant Fabrics poses no significant health hazard

to wearers.
