Have you ever just wanted to throw out your machine. Well this morning on my Brother pr1000 the thread on needle 8 kept breaking about every 50 stitches, I would just take a deep breath and re-thread the needle. I am so happy it has a needle threader, I changed the needle, replaced the bobbin and even played with the tension. So after the 30th time I pull out the book, so far I have done almost everything. With the last 30 stitches of course the thread breaks again at last unto another color .
One of the reason the thread breaks is says is BAD THREAD or WEAK THREAD. Being the type of person I am I re-thread another colour in the same needle ( it has 10) just to see if this could be ture . Yes it was the reason for all the breakage, now I will label the thread and not use it in that machine.
This is only maybe 3 years old, kept in a box in a drawer, so my QUESTION is. Should thread have a expiration date on it?
I am still using rayon and polyester thread I bought 20 years ago and cotton embroidery thread that I bought in the 60s. On the other hand I have fairly new rayon that breaks every few stitches and is put in the reject bin - different brand than my usual.
And like some others have commented I have thread that is many years old and some new and it is usually the new stuff that causes problems. Maybe that thread didn't like that needle spot.?.?..
Try putting the thread in the fridge or freezer for a few days to see if that makes it behave better.
Cannot recall if it is the fridge or the freezer where you need to place the thread to revive it - can someone else check?!?)
