Summary: | New nonwoven products containing cotton and Lyocell (Trademarked, Tencel), low temperature thermal-bondable bicomponent olefin/polyester, or comber noils were developed using needlepunching and spunlacing (hydroentanglement). Webs containing five different blends were prepared by either light needlepunching, or light needlepunching followed by hydroentangling. We acquired detailed basis weight uniformity measurements to learn about processing and the influence of fiber blend composition on web uniformity. Basis weight uniformity was evaluated without regard to web direction (“Total” uniformity), along the machine direction (MD uniformity) and across the cross direction (CD uniformity) at numerous size resolutions. We observed that blending manufactured fibers (either Tencel or olefin/polyester) with bleached cotton and comber noil substantially improved basis weight uniformity of both types of nonwovens. We also observed that subjecting needled webs to hydroentangling significantly improved Total and MD uniformities. |
