Longitudinal and Transversal Behavior of Multifilament Yarn Subjected to Longitudinal Load Using Image Analysis

Abstract:

The understanding of textile yarns behavior is of paramount relevance for the textile industry, mainly for technical applications. This describes the research work to introduce an alternative method for both yarns diameter and volumetric measurement using image analysis. Its main goal is to better describe the transverse dynamic behavior of multifilament yarns when submitted to tensile loads. Methods for measuring yarns diameter found in the literature are described and discussed. The proposed method presents significant advantages allowing the possibility to perform tests without interruption, as well as the ability to generate a greater amount of data, providing more accurate results. Longitudinal tensile tests using two types of multifilament polyamide yarns were performed and their actual dynamic behavior is analyzed using the experimental results.
