Spun Polyester Thread FAQ
What is spun polyester?
Spun polyester is a thread made from twisted polyester staple fibers. You may hear it called spun poly, and you’ll usually choose it when you want a softer sewing hand with reliable everyday durability.
How is spun polyester different from polyester core thread?
Spun polyester uses staple polyester fibers throughout the thread. Polyester core thread uses a filament polyester core wrapped with fibers, so you’ll often choose core thread when you need higher strength or higher-speed sewing.
What is spun polyester used for?
You can use spun polyester for garment assembly, overlock seams, serging, and general sewing across many fabric weights. The right size and product line depend on your material, seam type, and production needs.
Is spun polyester low lint?
Spun polyester can create more lint than filament thread because it’s made from staple fibers, but well-made spun thread is designed to sew smoothly and consistently. If low lint matters most, match the thread to your machine setup and application.
Which spun polyester product should I choose?
Choose Pro-Spun when you need smooth, uniform performance for light- to medium-weight fabrics and overlock work. Choose Astra™ when you need stronger sewing performance for cost-sensitive apparel production, and choose Excell® when you want a versatile staple spun option for general sewing across light- and heavy-weight garments.
