Perma-Core® 
 
Made with polyester continuous filament core and a polyester staple wrapper, Perma-Core® is a high performance corespun thread designed to minimize sewing problems and maximize seam quality. It's stronger than other spun thread constructions, which means you can use a smaller thread size without loss of strength. Smaller thread sizes help to reduce seam puckering on today's space-age fabrics. Perma-Core® delivers the ultimate in sewability on manual and automatic multi-directional sewing machines with Anetrak® proven results.
 
Performance You Can Count On
 
100% polyester construction
  • Improved seam strength
  • Superior colorfasteness
  • Recommended for signature contrast stiching that will fade during laundering

  • Recommended on garments that must maintain color consistency after many wash cycles
  • Recommended for garments that will be subjected to enzyme, stone, and chemical washes
  • Excellent resistance to micro-organisms, mildew, abrasion, ultraviolet radiation, and chemicals

Superior strength per size - higher tenacity

  • Allows the user of finer sizes to minimize seam puckering due to structural jamming or excessive tension
  • More yards per bobbin - few bobbin changes

Excellent sewability due to enhanced ply security and a higher initial modulus - Anatrak® proven results

  • Minimizes interruptions on thouse tough sewing operations including automatic pocket setters, and zig zag machines, etc.

Unique low friction thread lubricant giving improved stitch and seam appearance
