  • Bonded Nylon
  • Bonded Polyester

What type of thread is best used for sewing upholstery fabrics?

Q. I'm sewing on several different fabrics; marine vinyl, thick upholstery fabric, and canvas/duck cloth. What type of thread do you recommend I use? I need it to be strong enough to handle my high-speed Juki (it's an industrial sewing machine) and I don't want the color to fade. I've used other threads and it seems that for some reason it is breaking at the needle because of friction? Please help me find what I need.

A. We have several options for you. Let's start with each fabric type. For Marine fabric, we know that it is going to see a lot of sunlight and UV exposure. Nylon is not recommended for sewing if the end product will be exposed to UV rays. Bonded polyester is a good choice for any outdoor furnishing, as it has superior UV resistance compared to bonded nylon. It is a very strong thread and the bonding agent which is coated on the thread cuts down its susceptibility to wear from friction/abrasion.

For any indoor-sewing application, Bonded Nylon is a great choice. It is a very strong, colorfast thread. Our Bonded Nylon threads are also available in many different thicknesses, from #46 to #346. We personally use and recommend Groz-Beckert needles when sewing with our upholstery threads.
