Is black thread really weaker than the other colors? We get this question quite a bit. The answer is:
Black thread may be weaker than other colors if the thread has been over-dyed.
**We guarantee that Superior Threads products are never over-dyed.**
Some companies put all the mis-dyed colors in a reject bin and then over-dye them black. The excess amount of dye in these over-dyed threads can cause the fibers to weaken.
We believe in offering only the finest quality products, manufactured under the most strict guidelines. We do not sell any seconds.
We have black thread in most of our thread lines. Please be assured you are getting only the finest quality thread and none of them are over-dyed.
