Understanding Fiber Spinning: The Impact of Fiber Spinning

摘要

The spinning of yarns for textile and industrial applications now exceeds several hundred billion pounds per year. These yarns are characterized by high uniformity and complex morphology. Key variables include the stress applied to yarn during spinning, the temperature history of the yarn and conditions of yarn storage. Starting chemistry, especially molecular weight and molecular weight distribution are also key to final yarn performance. Utilizing multiple thermal analysis techniques, it is possible to correlate all aspects of fiber processing with TA response, allowing for accurate diagnosis of probable process causes of fiber property deviations. Utilizing similar techniques, it is possible to reverse engineer products and identify process variable likely to produce similar performance profiles on a given processing platform. The integration of multiple TA and other characterization methods have led to the formulations of models of structure formation during spinning that provide direction in the creation of new fiber products and process-structure-property concepts that are applicable to more complex polymer processing such as film formation and injection molding.
