✦ Synopsis

Abstract

The photooxidative degradation of acrylic fibers was investigated with two different fiber‐spinning processes, that is, dry spinning and wet spinning. Several analytical methods were used in this study: viscometry, X‐ray diffraction, Fourier transform infrared spectroscopy, optical measurements, and mechanical testing. Viscometry was used to determine the molecular weight as a monitoring factor for degradation. X‐ray diagrams showed lower changes in the crystallinity of wet‐spun fibers during a weathering process by irradiation. The results from mechanical testing indicated that the tenacity of dry‐spun fibers had less deterioration than that of wet‐spun fibers. Degraded wet‐spun and dry‐spun fibers showed similar trends in optical and spectroscopy analysis. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2009

Because of the environmental considerations, recycling is becoming a very important factor in any production planning within the fiber industry and textile industrial sectors. One of the determining factors for recycling of fibrous assemblies into fiber is the spinnability of the incoming material.
