Poly Poly Corespun Sewing Thread
Engineered to merge the strength of polyester filaments with the softness of polyester fibers—ideal for high-speed sewing across denim, bedding, apparel, and upholstery.
Product overview
Mahalaxmi’s Poly‑Poly corespun sewing threads combine the tensile strength of continuous polyester filament with the soft, fibrous wrap of polyester staple — creating a balanced thread that’s ideal for both speed and comfort. The filament core delivers strong, durable seams, while the spun outer ensures a smooth, soft finish that minimizes fabric abrasion.
This versatile thread suits a wide array of industrial sewing needs where both machine performance and end‑product aesthetics are critical. Whether overlocking a denim seam, stitching a comforter, or finishing a blouse, the corespun construction delivers reliable performance from machine needle to final garment or textile.
Available in multiple deniers, a broad color palette, and seamless compatibility with high‑speed sewing machines, Poly‑Poly corespun threads offer consistent quality “spool to stitch.”
