I am going to be sewing upholstery weight leather, dog leads, dog collars, leather rifle cases, thick fabric Sherpa type fabric and sunbrella type materials for dog related items. I am now going to be using a Juki 1541s flatbed sewing machine. I have had no problems using bonded nylon in the past with other machines that I have owned but need more thread so my question before I order more is what are the pros and cons to using bonded nylon thread verses polyester.

Any information, comments or advice is appreciated.

Thanks in Advance,

kgg

Visually and sewing with them, they are difficult to tell apart.  The polyester thread should be used if your product is going to be in the sun a lot as it resists uv damage better.

First off: I have absolutely no connection with the company in the address I am going to give you. This is an excellent article for just what you are wanting to know.

kgg,

I have mostly bonded polyester thread myself, as my commercial sewing experience began with Sunbrella fabric, canopy covers, awnings, patio furniture, that type of thing, all for outdoor use. I'm going to be experimenting with nylon thread myself, as I'm moving into leather work too. I say experiment! get a couple small cones and see what you think of the bonded poly. With sunbrella fabric and the ideas you have for your dog collars (which may be outdoors quite a bit?) I say you probably will like using bonded poly thread. However,  how long the threads can withstand the outdoors will also have to do with what part of the country the products you make are used in. In other words, do these Sunbrella dog collars and sch get exposed to the Arizona sun? For how long? All things to consider.

Perhaps the items that you make are just for yourself and you will only have to think of the climate/temps in the area where you live, whatever that is, and how many hours a day the items will be outdoors in the hot sun. However, if you are making these items for others and sending them to different climates, I would consider going with a bonded poly for sure. Just my opinion.

If your products would be subjected to extreme heat you may even want to consider kevlar thread - which is quite expensive. I have had Customers request it, then change their mind when they find out how much you have to add to your "Materials" fee. I have only had to use that a handfull of times and have just one cone of it, in black. LOL.

By the way, Ferg recommended a great website (sailrite.com) for information on threads.

Good luck!

I could be corrected and welcome it. Saying that I, understand they intended to make or keep a strength type specification when making a specific size thread. 

The one recomendation I will push is, buy new thread from a company. Another tip is keep these out of the sun in your particular storage. 

I found it pretty darn easy to get any brand name and any of their special threads “ if “ My size stayed under 138. Something I think is noticeable and weather it changes a decision or not its progress or invention, this has influenced threads for sewing. 

 

Good day

Thank you all,

What I have gathered is if the thread is going to be exposed to a lot of UV then use poly otherwise bonded nylon. Most of the items I make except for the leather dog collars / leads will be used indoors so I guess I will stick with the bonded nylon and just pickup a cone of poly.

Here is the most information I've seen between the two, and I'm even more confused after reading and studying both.

Nylon threads are strong, inexpensive, and easy to use with leather. I like to use them when I work with belts. As was said by other members, nylon is better for products that are not going to be outdoors (for a long time). Polyester is a better choice for anything used outdoors because of its sunlight (UV) and mildew resistance. I think you can try polyester because you are going to sew rifle cases and dog leads. You can read more about nylon and polyester threads here https://www.superiorthreads.com/education-thread-for-sewing-on-leather and if you will choose polyester you can find more about brands here https://sewingland.org/best-sewing-thread/. As for me, I'm using HAITRAL polyester threads when it is needed.

After much investigating, reading technical specs and my own testing I have mostly converted to 1lb cones of Coats Dubond Bonded Polyseter and for Bonded Nylon I use A&E thread. The cheap Chinese stuff, particularly black bonded nylon in 8 oz cones, doesn't hold a candle too either. It is a little more expensive but much, much better quality.
