Use standard cellulosic as a warp (eg cotton or viscose) and 100% Kanecaron PE as a weft. A minimum of 40% Kanecaron PW is recommended as a percentage of the total fabric weight.
Kanecaron PE is a very special modacrylic (modified acrylic) fibre that is inherently flame retardant.
Kanecaron PE has excellent charring characteristics as well as superior flame retardant properties (LOI 34). These, combined with a cellulosic warp, produce ideal FR upholstery fabrics resulting in a beautiful and cotton-like look.

This is of critical importance in upholstery fabrics, where the charred area (formed after burning) creates a barrier that prevents any substrate (such as upholstery foam) from igniting. The cellulosic warps combined with Kanecaron PE (which together exhibit excellent charring characteristics), are an ideal combination. Conversely flame retardant polyester exhibits a melting behaviour.
