¡  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.

¡  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%.
