Role of Fiber Finish in the Conversion of Fiber to Nonwovens Part 3: Finish Performance as a Mechanical Processing Aid in Needlepunching

Abstract

This part of the study aims to investigate the role of fiber finish during processing on the needlepunching machine. Certain key response parameters like dynamic needling forces and needlepunched fabric properties are analyzed for any possible effect of finish level and its uniformity on these responses. The experiments were performed using polyester and polypropylene, two of the most commonly used fibers in needlepunched products, to investigate the difference response due to fiber type. While the results published in Part 2 of this study showed that finish uniformity fail to show any effect on carding processability, it was found to have a significant effect on needlepunching forces and needled fabric properties.
