The top thread is the upper, visible thread in your seam, while bobbin thread sits underneath. If you need a matching lower-thread option, Sunguard+ Bobbins gives you prewound bobbin thread that can speed up production.
Bonded polyester is polyester thread with a coating that reduces fraying and improves abrasion resistance. For outdoor use, Sunguard+ Top Thread B92 is a practical choice when you need UVR, or UV-resistant, performance for sun-exposed sewing.
If you’re sewing upholstery, footwear, and marine work, ULTRA DEE® Top Thread gives you a bonded top thread that feeds smoothly and holds up to demanding seams. Thread size tells you how heavy the thread is, and a larger B number usually means a thicker, stronger thread.
When you need a bolder seam on heavy materials, Sunguard+ BOLD UVR Bonded Polyester Size B207 / T210 8 oz fits common B207 / T210 applications. For demanding industrial seams, Hercules Heavy-Duty Polyester Thread gives you a heavier polyester option built for strength and durability.

Polyester Sewing Thread FAQs
What Is Polyester Sewing Thread Used For?
You can use polyester sewing thread for upholstery, outdoor products, marine goods, repairs, garments, and industrial sewn items when you need strength, color retention, and resistance to moisture and abrasion.
What Is the Difference Between Top Thread and Bobbin Thread?
Top thread shows on the top side of the seam and usually carries more of the visible stitch appearance. Bobbin thread runs underneath, and you’ll often match it to your top thread for balanced seam performance.
What Does Bonded Polyester Thread Mean?
Bonded polyester thread has a finish that holds the filaments together, which can reduce fraying, improve abrasion resistance, and help the thread run more cleanly through your machine.
How Do I Choose the Right Polyester Thread Size?
Choose thread size based on your material weight, the seam look you want, and what your machine can handle. B69 fits lighter work, B92 is a common all-around size, B138 is heavier, and B207 / T210 fits bold, heavy-duty seams.
Is Polyester Sewing Thread Good for Outdoor Use?
Yes, polyester sewing thread can work well outdoors because it resists moisture and wear. If your project will sit in the sun and weather, you’ll want a UVR or outdoor-rated line for better long-term performance.
