Nomex® and CoolTouch Nomex® blends

10 Questions about Laundering NOMEX® and Cool Touch® NOMEX® Blend Garments at Home Wash

1. Can I wash these garments at home?

Yes. As long as washing recommendations are followed and the garments are not soiled with contaminants you would not want to mix with your family wash, they may be combined in loads.

2. Are there any special instructions?

Pre-treat oily, greasy stains with products like "Shout®" or "Spray 'N Wash®". Separate light colors from dark colors as staining can occur. Do not overload the washer. Garments need room to move in the wash for proper cleaning and good wrinkle recovery.

3. What wash cycle and water temperature should I use?

Wash in soft water with less than 4.0 grains of hardness. Hard water contains mineral salts that can form insoluble deposits on the surface of fabrics that can negate the flame resistant characteristics or serve as fuel if garments are exposed to an ignition source. Use the Permanent Press cycle in water temperature up to 140°F. Use any typical home laundry detergent. Do not use "tallow soap" as it can leave a film on the fabric.

4. Can I use chlorine bleach?

No. Chlorine bleach will weaken the fabric and accelerates color loss. Oxygen bleaches may be used if necessary. Oxygen bleach is found in some home laundry detergents such as Tide with Bleach®.

5. What about other laundry aids?

Starch, fabric softeners, and other laundry additives can coat the fiber and mask the flame resistant performance. They may also serve as fuel in case of combustion. Their use is not recommended. NOMEX® has a static dissipative fiber in the blend to reduce nuisance static.

6. What about drying?

Tumble dry on Permanent Press cycle with proper cool down. Do not overdry. This fabric is synthetic and should dry quickly. Remove promptly and hang or fold. Do not line dry in direct sunlight.

7. Can I iron or press these garments? These are not durable press garments and may wrinkle in laundering. Press with a warm iron on the Permanent Press setting. If creases in pants are desired, pressing will be required.

8. Can these garments be dry cleaned?

Yes. Either petroleum solvent or perchloroethylene can be used. In cases of heavy, oily soil, this may be the preferred approach.

9. How do I repair these garments?

Minor repairs that do not affect the integrity of the garment may be made by either sewing on NOMEX® fabric patches or by darning small holes with NOMEX® thread.

10. Can the FR properties be removed?

No. NOMEX® is inherently flame resistant. This property cannot be degraded or diminished by laundering. However, it is critical to remove greases, oily soils, and other flammable contaminants as they can burn independently and overwhelm the FR properties of the fabric. If home laundering does not provide adequate cleaning, professional care may be required.

How flame-resistant fabrics work

Flame-resistant (FR) fabrics and garments are intended to resist ignition, prevent the spread of flames away from the immediate area of high heat impingement, and to self-extinguish almost immediately upon removal of the ignition source.

Normal work apparel will ignite and continue to burn if exposed to an ignition source such as flame or electric arc. Everyday fabrics will continue to burn until they are extinguished or all flammable material is consumed.
