¡ The DREF spinning process manufactures yarns composed of a core covered completely by staple fibers.
¡ Allows creation of hybrid yarns-‐combining the best properties of core yarn and sheath fibers.
¡ DREF yarns provide the best durability as compared to other core spinning processes
¡ NOR*FAB Corporation operates the largest collection of DREF III yarn spinning equipment in the world.
¡ Yarn sizes ranging from 41 to 1000 tex.

Yarns for: ¡ Braiding ¡ Knitting ¡ Weaving ¡ Wire & Cable ¡ Cut Resistance ¡ Clutch Facing & Brake Linings
¡ Thermocouple Insulation ¡ Aerospace
¡ DREF yarns provide superior abrasion resistance, durability and strength.
¡ Enables the development of individually engineered yarns to meet customer needs.
¡ Superior cut resistance as compared to ring spun yarns § Allows for hardened cores such as fiberglass and wire to further enhance cut resistance
¡ Excellent thermal insulation ¡ Outstanding value versus lower performing yarns
Fabric Cut Protection (ASTM 1790-‐97, CPPT (g)
100% Para-‐aramid ring spun fabric 700 g
Hybrid Ring-‐Spun / DREF-‐Spun woven fabric with hardened core, such as NOR*FAB CutPro™ Style 10TT366
3200 g
Ø The example above compares Para-‐Aramid woven fabrics of similar weights except that Style 10TT366 is woven with DREF-‐Spun yarns that have a core of stainless steel. The result is an improvement in Cut Resistance of 450%.
