Thread: Bonded Nylon vs Polyamide 66?

[SpruceMoose]

Does anyone have much experience between the two? I'm tempted by some of the colors offered by Black Crown Threads, but do not want to switch the machine between differing materials and having to reset everything.

Wondering if any of you have much experience with it, or should i just stick to the tried and true bonded nylon.

I am sewing on a Techsew 2700. Medium weight items, I like a thick showing thread. New to machine sewing. Just shopping around for threads

 

Thanks!

Without knowing what you are sewing, it's hard to suggest a thread.  But I have no experience with "polyamide 66" threads.  I just wanted to pop in with a couple of pieces of advice...  Stick with a well-known quality brand of thread.  Stay away from cheap threads, as they'll only give you trouble.  Personally I stick with A&E Sunstop bonded poly thread, and their Canadian office is here in Montreal and their prices are better than elsewhere I've found.  You say you don't want to have to "reset everything" regarding thread... be aware that you really MUST learn how to adjust tension for different threads, as even if you stick with one brand of thread, often switching colors requires a tension adjustment.  Black thread for example is often stiffer than other colors (due to the dye is my understanding) and tension needs to be adjusted when switching.  And even different materials and thicknesses need tension readjustment.  So you should be comfortable with those adjustments.

On my industrial machines I almost exclusively use v92 Sunstop, sometimes on my Techsew 2750 Pro I use v138.  And I can get away with v69 (Sunstop again) on my domestic machine unless I'm doing clothing with thinner thread.

Have fun!

@SpruceMoose - I just took a look at Black Crown threads... the prices are more expensive than the Sunstop from A&E.  As a matter of fact, they're more expensive for a 1/4 lb spool than A&E is for 1/2 lb.  And a Google search tells me that "Polyamide threads are shiny, very strong, and also a little bit elastic. It can be used for basic sewing and also for technical purposes."  Personally I would stick with bonded nylon or my own choice, bonded polyester like Sunstop.

BTW, you can't order online from A&E, you have to phone them. American & Efrid... 800-361-6073

I use bonded nylon and bonded polyester thread from A&E as @MtlBiker has suggested, in sizes V92, V138 and V207 in 1 lb spools with no problems unlike the cheap Chinese stuff that is just an exercise in frustration. I haven't used the Polyamide 66 sometimes referred to as Bonded Nylon 66. The selling points that I see being advertised are:

 i) Stronger

ii) Less friction,

iii) Higher heat tolerance when compared to standard Nylon thread.

However, I can't find information to support those claims. The best I can find ( Dunmore Thread Size & Thickness Chart on the www.buckleguy.com/dunmore-thread-bonded-nylon-66-color-size-card/) is V69 has 0.5 lb more breaking strength then bonded nylon while V92 and V138 have the same breaking strength. Typically the cost of the thread is a lot more expensive then brand name threads. For my stuff I really can't justify the major cost difference without technical information. In the case of the Black Crown Thread in V92 it costs $25.50 CAD for 4 oz or $102 CAD for 16 oz (1lb) whereas I can get 1 lb V92 spool from A&E for $60 CAD. Also A&E threads are made in both Canada and the USA. Another Canadian alternative would  be Cansew ( cansew.com ).
