The Tearing of Plain Woven Fabrics Made From Ring, Open End, Twistless and Twisted Bonded Yarns

Abstract

The theory relating to the tearing of a plain woven fabric is developed to include the dynamic effects in the damped mass-elastic system. Experimentation with a variety of staple yarns shows that the mass elastic response has a significant effect on the behavior of the fabric undergoing tear. In particular, the intermittent slippage of the yarns from the body of the fabric into the del zone is of great importance. The greater the number of unbroken yarns in the del zone, the greater is the tear strength for a given yarn.
