There are different ways to make fabrics flame retardant and washable, depending on the type and composition of the fabric. Some fabrics, such as polyester, are inherently flame resistant, while others, such as cotton, need to be treated with chemicals to achieve the same effect.
Additives to make fabrics more Flame retardant
- You can use a homemade solution of borax, boric acid, and water to soak the fabric and then let it dry. This will create a fire-retardant coating on the fabric that can withstand washing.
- You can buy a commercial fire-retardant spray or liquid and apply it to the fabric according to the instructions. Some of these products are washable, while others need to be reapplied after washing.
- You can use a special coating technique that involves a flame-retardant polymer (like VAE) and a cross-linking agent. This method can create a durable and washable flame-retardant fabric that can resist high temperatures.
- You can also look for fabrics that are certified as fire-retardant by international standards. These fabrics are made of 100% polyester and have undergone rigorous testing to ensure their safety and quality. They are also easy to wash and maintain.
What is a VAE polymer
VAE polymer acts as a binding agent or glue that sticks flame retardant additives permanent to textiles. Crosslinking Washable grades are available. Crosslinking takes often place at high temperatures. (eg. 150°C)
VAE polymers offer:
- Low flammability, in relation to Styrene based polymers like SB (styrene butadiene) https://www.youtube.com/watch?v=xJ6zcCkeKwU
- Low VOC (only low emissions of acetic acid, no styrene
- High compability (sollubility) with additives
- Colour stability (non yellowing, high flexibility, no brittle-ageing)
