Talk about novelty yarn! For my birthday this year, Keith gave me some Kevlar Yarn. That's right... yarn that is made out of KEVLAR. This is the strong material that is used in bullet proof vests and more.
According to Dupont, "Needled felts of Kevlar® have excellent cut and heat resistance and offer good protection against punctures. Because of their stiffness and shedding of fibers during material handling, needled felts are rarely used as outer fabrics. They are typically used as substrate materials."
