tortoise 40S/2 Polyester Sewing Thread — 8 Cones (2743 m Each) Grey, High-Strength & Low Hairiness

Tortoise 8 cones of 3,000 yards each (24,000 yards total) is a high-strength grey 40S/2 polyester sewing thread built for everyday sewing, serging, overlocking and quilting projects.

These eight large cones deliver commercial-length thread in a neutral grey that suits mending, garments and home sewing. Made from 100% polyester and produced with advanced twisting and air-splicing techniques, the thread is designed to feed smoothly through high-speed machines and household machines alike. Each cone’s length and consistent finish reduce spool changes and thread breaks during long runs, while colorfastness and low hairiness make seams neat and durable.

How does this thread perform in high-speed sewing machines?

The Tortoise polyester thread is manufactured to withstand continuous, high-speed stitching thanks to tight twisting and air-splice joins that minimize weak spots. It’s treated with a controlled silicone finish to improve lubrication and reduce friction, so thread breakage and machine stops are less frequent.

• 3,000 yards per cone for fewer spool swaps
• Air splicing reduces visible joins and weak points
• Silicone finish lowers friction for smoother feeding
• Compatible with most domestic and industrial machines

Will this thread work for quilting, serging and overlock applications?

Yes—the 40S/2 polyester balance provides a good mix of strength and softness suitable for quilting, serging and overlocking. Its low hairiness and solid breaking strength create tidy seam lines and consistent stitch formation across multiple fabric types.

• Low hairiness means fewer lint buildups and cleaner stitches
• Breaking strength mean value above 11 N supports heavy seams
• Suitable for cotton, blends, synthetics and layered quilts
• Neutral grey blends well with many fabric colours

How durable and colourfast is the polyester thread?

The thread is 100% polyester, which resists shrinking and fading better than many natural fibres. Independent performance measures show colour fastness to washing and sunlight at around level 4 or higher and consistent dimensional stability, so seams retain appearance after laundering.

• Colour fastness to washing and light ≥ level 4
• Low shrinkage and stable colour during routine washing
• Breaking CV (%) typically between 5.5–7.5 for consistency
• Hairiness under 0.3 at 4 mm for tidy stitch definition
