Abstract
The present invention provides a process whereby high quality, well-coalesced spandex can be made by dry-spinning a high-melting thermoplastic polyurethane, bundling the as-spun filaments into a side-by-side relationship, and passing the bundled filaments over or through a guide. The spandex made by this method has high-heat settability, high denier uniformity, good knittability and weavability, and provides fabrics having good surface uniformity.
