How is this thread different from other conductive threads?

SewIY conductive thread is a novel multimaterial composite braid.  Most conductive threads are made by twisting yarns made of spun conductive staple fibers.  Some threads use traditional textile materials that have been surface-treated with silver or other conductors.  For comparison, even the highest quality stainless steel conductive threads:

-Are not insulated

-Are not solderable

-Are noticeably stiffer and coarser

-Are more difficult to sew with

-Have 21 times or greater linear resistance 

-Have significantly lower current carrying capacity
