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.”
