This study delves into the low-stress mechanical properties of various woven and knitted cotton apparel fabrics using the Kawabata Evaluation System for Fabrics (KES-FB).
Fabric hand significantly influences the overall quality of apparel fabrics. It is influenced by both fabric structure and the low-stress mechanical properties of the materials employed. Fabric hand is a multifaceted property intertwined with fabric behavior during various deformations such as tensile, shear, compressional, and bending. Additionally, surface characteristics like friction and roughness play a crucial role. When we touch a fabric, we subject it to these deformations, and nerve endings in our fingers sense resulting sensations, giving rise to subjective perceptions of fabric hand.
The KES-FB system replicates this scenario by quantifying low-stress mechanical properties of fabrics, predicting sensations such as softness or crispness via a set of transformation equations. Kawabata and colleagues developed transformation equations linking these mechanical properties to subjective hand assessments made by expert judges. Consequently, the KES-FB system can anticipate the Total Hand Value (THV) for specific end-uses based on fabric properties measured.
