Isalon is the brilliant and strong machine embroidery thread for all applications. Produced from high-sheen top-quality trilobal polyester, Isalon combines the brilliance and softness of viscose with the wearing properties and technical superiority of polyester. Isalon is colorfast to bleaching as a polyester, but operates much like a traditional rayon thread. Some strong advantages of Isalon are in the fine details such as small lettering.
