IMPORTANT INFORMATION ABOUT YOUR FR GARMENT
Flame Resistant (FR) refers to the ability of a material to self-extinguish upon the removal of an ignition source. FR is a short name for Flame Resistant Protective Apparel. Remember Flame Resistant Clothing is NOT fireproof.
FR garments will not provide significant protection from burn injury in the immediate area of contact with the ignition source. However, flame resistant garments do provide protection against clothing ignition and sustained flame spread. Remember, FR garments are NOT fireproof.
National Fire Protection Association (NFPA) 70E Standard for Electrical Safety in the Workplace states that non-melting, flammable fiber undergarments may be used in conjunction with FR garments. Flame resistant t-shirts, henleys, and base layer garments can provide additional wearer protection.
WHAT TYPE OF FABRIC DOES KOLOSSUS USE?
Flame-resistant twill designed for comfort that meets NFPA 70E and NFPA 2112 standards.
FR Twill 88% CO 12% PA 7 oz/yd2 – UL Certify for NFPA 2112 cat. 2 and NFPA 70E – ATPV 9.9 CAL/CM2.
IMPORTANT INFORMATION ABOUT YOUR FR GARMENT CARE
DO NOT USE Detergents with Bleach such as Tide with Bleach
DO NOT USE Chlorine Bleach
DO NOT USE Detergents that contain animal fats*
DO NOT USE Fabric Softener or Dryer Sheets*
*These are Flammable
Never Spray DEET on your FR garments, it is highly flammable. If you must use DEET, apply it direct to the skin and NOT the garment.
GENERAL GARMENT CARE CONSIDERATIONS
These garments can be laundered at temperatures normal to cottons.
Flame resistant garments should be removed immediately and replaced with clean FR apparel if they become fouled with flammable materials.
Flame resistant apparel should be washed using soft water (less than 4.0 grains). Hard water adversely affects cleaning, resulting in increased detergent usage. Hard water contains mineral salts that can form insoluble deposits on the surface of fabrics. Sufficient buildup can negate the flame-resistant characteristics of the garment, and may serve as fuel if garments are exposed to an ignition source.
These garments should not be worn where contact with strong oxidizers (e.g., >10% sodium hypochlorite, NaOCl) or reducing agents (e.g., sodium hydrosulfite, NaS2O4) is a consideration.
It is important that formulas are developed using detergents and wash temperatures (up to 165ºF) adequate to thoroughly clean all contaminants from garments.
- Use non-ionic formulas. Do not use natural soaps (anionic or tallow soap) or silicate supplemented detergents. Soft water is recommended. Hard water precipitates soaps. It also contains calcium and magnesium salts. These products can build up on the fiber surfaces, coating the fabric and masking FR properties.
- Chlorine bleach (sodium hypochlorite) and hydrogen peroxide (oxygen bleach), whether separate or contained in detergents, must be avoided. Repeated exposure to bleach can destroy the FR polymer and make the garments nonprotective.
- Starch, fabric softeners, and other laundry additives can coat the fiber and mask the FR performance or serve as fuel in case of garment ignition. Therefore, their use is not recommended. Garments should be soured to a pH between 5.5 and 6.5.
- If garments are heavily soiled with particulate or abrasive soils, a flush at the beginning of the cycle will help reduce abrasion in the wash wheel. Wash formulas and load sizes should be set up to minimize redeposition and fabric abrasion.
- Extract by methods typically used for regular 100% cotton garments.
- Condition at a stack setting of 165°F so fabric temperature measured in the basket does not exceed 280°F. Normal shrinkage of 5 % to 6% can be expected. As with any 100% cotton fabric, excessive shrinkage may occur if overdried.
- If desired, garments may be pressed using normal cotton pressing techniques.
- Use any typical home laundry detergent. Powdered home wash detergents containing sodium perborate and other “color safe” bleach alternatives will not affect the flame resistance of the garments.
- Do not use chlorine bleach, liquid nonchlorine bleach or detergents that contain hydrogen peroxide. These include but are not limited to liquid Tide with Bleach®, liquid Clorox II®, and liquid Vivid®.
- It is important that all potentially flammable soils and other contaminants are completely removed from garments during the wash process. This may require the use of stain removal products, such as Shout®, Spray ‘n Wash®, or Zout®; or presoaking garments prior to washing. The use of hot water can often make detergents more effective in soil removal. If all contaminants cannot be removed in home care, you should obtain professional help in getting your FR garments clean.
- The use of conditioned or soft water can help improve removal of contaminants from garments. Hard water precipitates soaps and can result in the build-up of calcium and magnesium salts. These can serve as fuel in the event they are exposed to a source of ignition.
- Starch, fabric softeners, and other laundry additives are not recommended because they can coat fibers and mask FR performance, or serve as fuel in case of garment ignition.
- Do not over dry garments. If desired, you may press with an iron on the normal cotton setting.
- We recommend you turn garments inside out to help reduce streaking that can occur due to abrasion in the washer.
- Either perchloroethylene or petroleum solvent can be used. With petroleum, it is necessary to ensure that all solvent has been completely dried from the garments. Do not dry clean indigo dyed FR denim.
REPAIR & MENDING
- Minor repairs that do not affect the integrity of the garment may be made with like materials by either heat sealing or sewing on patches or darning small holes.
HOW IMPORTANT IS IT TO CLEAN FR GARMENTS?
Proper cleaning and maintenance of any flame-resistant garment is essential in order to remove potentially hazardous soils and to avoid a buildup of materials that could mask performance. This includes flammable soils and greases, as well as other contaminants such as a buildup of hard water ions that can coat fibers with flammable material. ASTM Standard F1449 Guide for Care and Maintenance of Flame, Thermal, and Arc Resistant Clothing is a good general reference for care and maintenance of flame resistant and thermal protective clothing. Always follow garment manufacturer’s care label recommendations and other published instructions or recommendations.
CAN BLEACH BE USED WHEN LAUNDERING FR GARMENTS?
No. bleach should not be used when washing FR garments and fabrics because repeated chlorine bleach launderings will destroy the flame-resistant finish. It is best to replace bleach with detergents containing bleach alternatives. Industrial laundry detergents containing hydrogen peroxide must NOT be used either.
To ensure continued flame-resistant performance, it is necessary to follow the manufacturer’s recommendations for textile maintenance processing of each type of flame-resistant garment. Whenever deviations from manufacturer’s recommendations are necessitated by local conditions, testing must be conducted to ensure that the protective properties are maintained through the expected service life of the garment.
ARE FR GARMENTS STILL EFFECTIVE IF CONTAMINATED WITH FLAMMABLE SUBSTANCES?Flammable substances on FR garments will ignite and continue to burn on the surface of the FR garment. Flame resistant garments should be immediately removed and replaced with clean FR apparel if they become fouled with flammable material. If laundering or dry cleaning cannot remove flammable contaminants, the contaminated garments should be removed from service.
