Nonwoven Fabric Studies

Abstract

The variation of tensile strength with test specimen length (jaw span) has been examined theoretically and experimentally for a range of nonwoven fabrics. It is shown that the plot of strength versus jaw span provides a basis for assessing the extent to which fiber strength is utilized in a bonded fiber system, weakness due to poor bonding being associated with a rapid increase in strength as the jaw span is decreased below the fiber length. By this method, the relative bonding strengths of several commercial nonwoven fabrics have been determined.
