Isacord is the thread of choice for maximum productivity and the highest quality embroidery among the largest embroidery houses. At nearly twice the strength of rayon thread, Isacord is the smoothest running and most reliable thread produced. It has been engineered from the finest raw materials to provide just the right amount of elasticity to allow for high speed running without looping or puckering while virtually eliminating thread breaks. ISACORD is a polyester continuous thread that has a comparable shine to a rayon embroidery thread. This is obtained through a special cross-section modified fibre. ISACORD is wash, boil, and lightfast and also has a high resistance to chlorine and abrasion. Therefore, ISACORD is the ideal thread used for extreme treated textiles, e.g. work wear, sportswear, jeans, catering wear, and leather. These listed examples can be washed with chlorine bleach or stonewashed without any problems.
