NYLON versus POLYESTER who

[Northmount]

Are you using the same type thread on top and bottom?  If not, one could be cutting the other.  This is just a guess.

yes I was using 277 top and bottom, and Bob I thought it was strange that it was braking thread with the brand new spool of thread.  I went ahead and ordered some more 277 in nylon and ran it through a test where I was going from sewing on 10oz and the lower knot was perfect and also tested by sewing to the transition from 10oz to 20ox in a step and sewed perfectly with no issues at all.  It didn't really surprise me that it did accomplish the job but with very little ease knots set perfect and no fraying or breakage.  So know like I had mentioned I will continue to use the nylon and hang on to the polyester for another trial run at a job that I can experiment with a little, before rendering a complete analysis on the polyester.

I'm am just guessing, do you think maybe that spool of polyester got too hot somewhere between manufacturing and you?

I've not had good luck with poly, however, I've gotten some bad nylon also.  Some of it just comes down to being poor thread to start with.  I don't know if it would be a random bad spool, or a bad run.  Most of the time, thread that won't work on top can be used on bobbins, but I've even had thread that didn't work on the bottom.  None of it was "bargain" or "odd lot" thread.  It was all standard stock from reputable companies.

In my start not so long ago I never had a tough time locating 92 size thread as thats all I needed and setup for. I did then rely on Coats for much homework in my learning some tips. 

When lucky to get a used big stitcher a State away. I really only then pursued some homework on locating what i first wanted in machine size so 277 it was. It seemed to me my brand homework choices were not easily avail in big thread, and or possibly renamed and or respooled. 

I would like to hear any choice in comparison size to hand stitch thread, cord and what many use. I recently glanced at tiger and seen 4 choices, this is just what i googled and so took a look see. 

Always interesting topic this thread thing, I cannot do and so smartly try and choose to have projects with similar thread needs. 

Coffee time, Good day!
