Understanding Thread Sizes and Sizing Systems

When it comes to thread, size matters. The numbers on the spool of thread reference the diameter size, with various sizing systems in use. There are a few different thread sizing systems, but the upholstery industry most commonly uses the TEX system. TEX uses a fixed length to measure the weight of 1,000 meters of thread in grams. For example, 1,000 meters of thread that weighs 1 gram would equal 1 Tex.  The higher the number the thicker the thread. Thicker thread will make your stitching more visible.  The tension on your sewing machine needs to be adjusted when you change thread weights, and you will need to use a needle that the eye is 40% larger than the thickness of the thread.

Types of Fiber

Threads are composed of different fibers, with Nylon and Polyester dominating the upholstery industry. Bonded Nylon is recommended for indoor projects, while Bonded Polyester is ideal for outdoor or UV-exposed applications due to its enhanced resistance to UV damage. Despite the differences, both offer comparable strength.

Styles of Thread

The high traffic and physical demands of marine environments require vinyl with superior abrasion resistance. Vinyl that can withstand friction, impacts, and general wear and tear will remain looking new for longer periods. Consider the vinyl's "double rub" count—an industry-standard measurement of abrasion resistance. Opt for marine vinyl with a higher double rub count to ensure your upholstery can endure the rigors of life on the water.
