A specialized coating on the surface of a fabric can increase its resistance to fires, UV, mildew and wicking. This can be done with a variety of techniques. Coatings can also be used to adjust light transmittance, allow graphics acceptance and give the fabric a smooth, flat or glossy finish.

The main goal of flame retardant fabrics is to make them safe from the contact with flames, while avoiding fire spreading to other areas of the fabric or to the wearer. The best way to achieve this is by weaving the fabric directly with flame retardant threads without any chemical treatment process. However, if the fabric needs to be further improved its FR performance, it can be treated with various coatings that are applied to the yarn or to the finished product.

One type of coating that improves the FR performance of the fabric is a fire-retardant breathable membrane. This is a layer that is bonded to the surface of the fabric, and it provides both a breathable and waterproof protective membrane. Usually, the breathable membrane is made from a highly durable material such as polyester or nylon, and it can be woven with other layers of fabric to create a garment that meets a specific set of standards for durability and comfort.

Another type of breathable waterproof protective fabric is a vinyl laminated polyester. This is a versatile material that can be woven with other layers of fabric, and it can also be made into a breathable and fire-retardant material. This is a popular choice for applications that require both the protection of a high-performance fabric and the need for the clothing to be comfortable in extreme weather conditions.

A third type of protective fabric is a combination of a flame retardant outer layer and a breathable and waterproof membrane. This is a combination that is often used in garments such as rain jackets, and it can be useful for those working in harsh environments where they need to be protected from both the elements and workplace hazards.

In recent years, a number of companies have developed a solution to this problem by making a fabric that is both fire retardant and breathable. This material, which is woven with inherently flame-retardant acrylic yarn and coated with a fire-retardant spray, has been named Recsystem FR and is widely used in the manufacture of commercial awnings and shade products.

Researchers created the fabric by dipping strips of cotton into a solution of polyethylenimine, which acts as a binding agent, and then in solutions of ammonium polyphosphate and silsesquioxane, a cage-like molecule that tends to be hydrophobic. They hung the strips over an open flame, and while the untreated strip quickly caught fire, the coated strips charred slightly and then extinguished. The resulting fabric can be washed repeatedly and still maintain its flame retardant properties. It can even withstand more than 1000 cycles of abrasion without losing its ability to self-heal, making it a multifunctional advanced textile.
