JD, I have complete nomex underwear from my road racing days back in the 80’s. None of it has an sfi tag, maybe because there was no sfi back then? As for the helmet skirt, I haven’t looked to see if they have sfi tags yet. One way or the other we’ll be legal before next season.
A question that has been asked before, Nomex does not wear out per the DuPont web site other than normal wear & tear. So my nomex should still be good to use other than a missing tag.
Normal home, commercial and industrial laundering and dry techniques are suitable. Because the flame -resistant protection is part of the aramid fiber it cannot be washed or worn out, even if the garment is mishandled. Recommended laundering procedures are available. Many companies consider industrial laundering programs to ensure their garments are thoroughly cleaned and properly maintained and to implement and manage their Protective Apparel programs.
Nomex® Protective Apparel garments are extremely durable and stand up well to repeated launderings and use. Fabrics have very low initial shrinkage (1 % to 3% ) and maintain their size and shape over the life of the garment. Nomex® Protective Apparel garments come out of the dryer ready to wear and rarely need pressing.
Chlorine bleach should not be used on Nomex® protective garments. Chlorine bleach or other additives will not remove the flame protection as they can with flame-retardant treated fabrics; however, to preserve garment strength and prolong garment life, chlorine bleach should not be used.
Caution: Thoroughly remove greases, oily soil and other flammable contaminants from Nomex® protective garments. Flammable contaminants serve as a fuel source and will reduce the thermal performance of any garment. Tears or rips should be repaired with components made from Nomex® brand fabric, sewing thread, zipper tapes and patches.
Now what I really like to know is how can we tell if we have Nylon or Polyester seat belts?
