Hello group,

  I really like sewing with braided thread at times.  I've been experimenting with different sizes of braided PE fishing line.  I've been using 42lb breaking 0.32mm diameter into a size 19 needle on the patcher and it works just fine.  We have some larger 0.5mm range that will work into a size 23 needle and have 80lbs breaking strength.  

  My concerns were proper forming on the stitch but it seems to be unfounded.  The only rules of the road are to feed sideways off the spool and not off the top with braided which I learned through experience and later verification.  Braided is not right/left twist sensitive.

  My other concern is if one is waxing the material it can be done with caution.  

  If anyone wants to provide input please do.  I just wanted to get opinions of others have tried.  I can also say the PE stuff is extremely slippery compared to other threads.  It's also super stain resistant.

Best regards,
Mike

My concern with fishing line is wear. Yes slippery but also tough. I am worried about wearing grooves into the thread path guides. To me, it seems similar to invisible thread and used the invisible fishing line at 6 lbs test i think, light stuff.

Hi John,

  Thanks for the reply.  This stuff is extremely slippery so I'm not thinking wear in thread paths is a concern any more than cotton would be.  Nylon is also a very abrasion resistant material while cotton itself is abrasive as a material.  This stuff is significantly stronger than mono filament fishing line and much more flexible  I have purchased braided and bonded polyester for sewing but usually that is 207 through 415.  Poly has higher melting points as does nylon so the nylon or poly thread would have a similar melting point to synthetic cloth if used.  I've heard folks talk about the possibility of high performance thread tearing the cloth before it breaks.  One can purchase high performance threads such as nomex (meta aramid) or kevlar (para aramad) but there are issues with kevlar as it is very susceptible to UV and both are extremely expensive. Another concern is the low stretch of high performance PE (a step down from UHMWPE ultra high performance PE).  My thought is that as long as it is not ironed with a ridiculously hot iron and if waxing the material (if used to sew canvas) it might be good.  Ultimately it may be better just to stick to braided and bonded poly but the problem is that 207 is as small as it gets from the US maker/supplier and it seems anywhere else so that is a jump from a size 19 needle to a size 23 needle which is significant.  I have some shirts made from UHMWPE that are cut resistant and come with special laundering instructions. Maybe just for very special applications and not much else.  For now I'll experiment with it.  Likely, there is a niche application window for it and not much else. Best regards, Mike  edited to add I just did a search after Bruce talked about how abrasive monofilament nylon is in SM tension discs.  The internet shows nylon not being a very slippery plastic which explains the abrasive nature of sewing with mon filament line.  PE, on the other hand, had some hits comparing it to the qualities of teflon for slipperiness so I'm thinking the wear in the tension guides just might be pretty low compared to other threads.
