Abstract: There is disclosed a method and apparatus for making strand material comprising drawing a laminar material having a first layer of drawable material and a second layer of elastically extensible material so that the first layer extends inelastically while the second layer extends elastically so that the drawn material tends to curl into a coiled strand configuration.

Abstract: The invention relates to internally bonded sewing threads and to processes for the production of the internally bonding sewing threads. The internally bonding sewing threads of the invention include three multifilament yarns wrapped helically about a thermoplastic bonding core yarn. Processes of the invention include an improved process for preparing a precursor plied thread which is thereafter thermally treated to provide the internally bonded sewing thread. In addition, the invention provides batch and continuous processes for converting the precursor plied thread into internally bonded sewing thread.
