The Cool-Sew finish was developed to alleviate needle problems resulting from the following situations:
1) Heat Buildup in penetration of synthetic, chemically treated, or very dense materials
2) Materials or residue sticking to needle surface or in eye
3) Excessive sewing thread breakage due to friction in the needle eye

The COOL-SEW finish needle’s surfaces, even in the eye, are resistant to sticking. Its non-stick finish has a very low friction coefficient which prevents excessive heat buildup and its resulting problems. Few, if any, materials stick to the surfaces of Cool-Sew needles.

When COOL-SEW needles are used under conditions described above you can expect neater stitches, less sewing thread breakage, less puckered stitches, less downtime, less defects, and increased productivity.

COOL-SEW needles are ideal for sewing through vinyl, synthetics, chemically treated materials, glued materials, rubberized goods, nylon, foam, dense materials, and with synthetic threads.
