RedwoodJen Report post Posted September 21, 2014 Hi all - I don't know the applications for when you want to use poly or nylon (or something else.) I just sewed up a leather halter the other day and used poly. Was that right? Also, these chaps will be hair on hide. Quote Share this post Link to post Share on other sites

JREESER1 Report post Posted September 21, 2014 Anything that will be exposed to sunlight (ultraviolet) will hold up better with polyester. Everything I have read says polyester resists mildew and abrasion better. All of my machine thread is polyester. I have had great service and response from The Thread Exchange.

Galloways Report post Posted September 29, 2014 POLYESTER! nylon depolymerises even in mild acid veg tannings are acid it disintegrates in contact with metal salts Chrome tan is tanned in metal salts as well as the already mentioned no UV resistance it's also abrasive and has high elasticity which is not good for your machine, it's just very cheap hence it's popularity on low end mass produced goods which fall apart in two minute. The Coats thread manufactures web site has the technical specs for different thread, they also have a thread cost calculator which is interesting shows how cheap the users of nylon are.
