Isacord聽 embroidery聽 thread聽is the聽 thread聽of choice for maximum productivity and the highest quality聽 embroidery聽among the largest聽 embroidery聽houses.
At nearly twice the strength of rayon聽 thread, Isacord聽 thread聽is the smoothest running and most reliable聽 thread聽produced. ISACORD is a polyester continuous聽 thread聽that has a comparable shine to a rayon聽 embroidery聽 thread. This is obtained through a special cross-section modified fiber. Isacord has been engineered from the finest raw materials to provide just the right amount of elasticity to allow for high speed running without聽 looping聽or聽 puckering聽while virtually eliminating聽 thread聽breaks.
ISACORD is wash, boil, and lightfast and also has a high resistance to chlorine and abrasion. Therefore, ISACORD is the ideal聽 thread聽used for extreme treated textiles, e.g. work wear, sportswear, jeans, catering wear, and leather. Isacord can be washed with chlorine bleach or stonewashed without any problems.
Quilting?
This 40 wt.聽 thread聽is thin, making it an excellent choice for free motion quilting designs that require a lot of travel stitching. Isacord is also very strong and able to take the high speed and intensity of machine quilting and聽 embroidery.
Many famous quilters recommend Isacord聽 thread聽for machine quilting for its strength and glide during long arm quilting. The聽 thread聽will never break through the fabric, even on quilts that have been washed multiple times.
What was true then is not true now. You CAN use high quality polyester threads on your quilts. The trick is to always use high quality materials because great聽 thread聽+ great fabric = excellent project.
