How To Care For FR Clothing

DickiesStore aim to keep the modern worker comfortable and safe while feeling protected and looking good!  Our range of flame retardant workwear is researched, designed and engineered by industry innovators and conforms to international safety standards.


Flame retardant clothing (or FR Clothing as it is commonly called) is utilised mainly by workers in the oil and gas industry, as well as those in welding and foundry environments. However, we are finding that fire retardant coveralls are also becoming more popular for leisure activities, such as motor racing.

While our garments are manufactured to the highest standards, flame retardant clothing requires special care in order to maintain its quality.

  • Firstly, do remember to check the label on the garment and launder according to the instructions. Many flame retardant garments are not suitable for industrial laundry.
  • Cotton, aramid and modacrylic garments can be laundered using the recommended temperatures and wash cycles. Some 3% minimal shrinkage can be expected and is a natural reaction from both the fibres and the weave construction, most noticeable during the first 3 to 5 washes.
  • Please take this expected shrinkage into account when purchasing your garment.
  • Be careful not to over dry garments. Exposure to excessive drying temperatures will result in higher than normal shrinkage.
  • Water which is too hard affects the cleaning process and may contain mineral salts which build up on the fabric. These types of deposits, in extreme cases of build-up, can actually exacerbate the flammability of the clothing and act as an accelerant if exposed to an ignition source.
  • Starches, fabric softeners, and other laundry additives should be avoided.
  • Do not use chlorine bleach or other detergents or chemicals containing hydrogen peroxide! These chemicals may coat the fibre used to treat the fabric and inhibit its flame retardant properties. Some of these chemicals can also act as a fuel.

Flame Retardant Treatments

Proban: A flame retardant solution designed to treat cotton or cotton rich fabrics. The polymer in the Proban treatment is embedded within the individual fibres of the garment and is insoluble. It cannot be removed by washing – only by mechanical abrasion or incorrect laundering. Proban fabrics meet the minimum standards required of 50 washes at 75°C. However, numerous independent tests have shown that Proban treated garments still pass this flammability test well after 100 to 150 washes.

Pyrovatex: One of the most widely used flame retardant treatments for 100% cotton fabrics. Cotton fibres are treated with a crosslink resin which ultimately creates a very strong, durable and protective link that makes the fabric resistant to shrinking or melting when exposed to heat and flame. Dickies Pyrovatex garments are made from high quality cotton, so they retain their lightweight properties and remain comfortable to wear.

Modacrylic: Monacrylic fibres are synthetic and blended with cotton for a natural feel and maximum comfort. These fibres are known for their flame retardant properties, as well as their resistance to chemicals and solvents. Furthermore, their flame retardant properties do not deteriorate after repeated washing or normal use over time.

Aramids: Aramid fibres are synthetic, heat resistant fibres. The high level of protection they provide does not come from chemical treatment, but is engineered into the molecular structure of the fibre itself. As a result, the heat and fire retardant qualities of the garment are permanent and will not fade over time.

Many of these garments can be made to order in different colours, and can be customized with your company’s logo. We utilise flame retardant thread when embroidering on these clothing items, so that they maintain their fire resistant qualities. Garments with a logo on them should therefore be treated the same way as an ordinary item of flame retardant clothing. For a free quotation, contact us today.

    I bought my son some coveralls from you and am now intending to wash them. The label states wash at 60 degrees and NOT to use soap or soap powder,or hypochlorite bleach. It states in red print; ‘wash with suitable detergents only’.
    Can you advise me the make or type of detergent you recommend?
    Previously my son experienced his older coveralls catching light from a spark and fortunately was not injured. I was unaware that they were fire retardant and washing them reduced the fire retardant aspect. In view of this I wish to make sure by washing this new coverall I will not make it no longer fire retardant.

    Look forward to hearing from you!

    • Hi Madeleine,

      Could you let me know the product code for the coveralls (it will begin with FR and should be on the garment label). I can then look into this further for you.

    Can I put the clothing in a dryer?

  3. just wondered what the name of the washing powder is which is suitable to use for washing flame retardant clothing?
    Please lmk asap.
    Many thanks.

    • Thanks for getting in touch Edith, great question! I have emailed you directly for further information on the garment you have or are looking to purchase as garment care does depend on the way in which the garment is treated to give you protection.

    Can you advise me of what would be a suitable detergent to wash Flame retardent overalls. The FR number found on the lable of the overalls is FR4869. Thanks in advance.

    • Hi Steve,

      Thanks for getting in touch.

      The following washing powders may be used:
      Fairy Non-Biological Automatic
      Surf Automatic Powder
      Persil System Automatic

      We advise to never use Acdo, Lux Soap Flakes or Persil as the use of soap in hard water areas can result in soap/calcium deposits which adversely affect the flame retardant performance of treated fabrics. Also do not use Domestos, Vortex or any supermarket bleaches.

      We hope this helps.
