50S/3 Fine Three-Ply Poly-Poly Core Spun Underwear Sewing Thread 5000yds

MH 50S/3 poly-poly core spun sewing thread is a fine, three-ply core spun thread built for stitching underwear and other close-to-skin garments. Each ply pairs a continuous polyester filament core with a polyester spun-yarn wrap, giving the thread the tensile strength of filament while keeping the soft, matte hand of spun yarn against the skin.

Key Selling Points

• Soft against the skin: MH poly-poly core spun sewing thread keeps the smooth, matte hand of spun yarn on the seam surface, so stitches stay gentle inside underwear and close-fitting garments.
• Wash-durable three-ply seams: The three-ply core spun build resists abrasion and holds stitches together through repeated home laundering, minimising open seams and broken stitches.
• Fine, low-profile stitching: The finer core spun construction produces slim, even seams that lie flat in lightweight intimate fabrics without bulk or puckering.
• Built for stretch fabrics: The filament core adds elasticity and strength, letting seams move with elastic knit and shapewear panels instead of snapping under stretch.
• Custom color matching: MH dyes the thread across an extensive color card with custom shades on request, so intimate-apparel makers can match trims and fabrics precisely.
• Certified production: MH produces the core spun thread to the OEKO-TEX standard, supporting compliance for skin-contact underwear and garment programmes.
