The "Super Synthetic Fiber Needles" (SU) industrial sewing machine needles (especially Organ Needle DB×1HP/SU, etc.) are designed to prevent fabric melting and thread clogging (skipped stitches/thread breakage) by suppressing the temperature rise of the needle due to friction heat when sewing materials that are sensitive to heat, such as polyester.
