The Optimization of Complex Hand Rate Determination
Keywords:
textile, hand, mechanical properties, complex rate, instrumental measurement.Abstract
The article presents an objective evaluation of textile hand during the extraction of a disc shaped specimen through a central hole. The influence of separate extraction curve H–P parameters on the numerical hand value is analyzed. Two types of the extraction curve parameters that determine force and deformational fabric properties characterize fabric be-havior during the extraction process. The optimal set of parameters for different fabric types is defined. The complex hand rate is expressed as the polygon area of a circular chart. The significance of parameters set arrangement in a circu-lar chart is established. Also two equations for textile hand determination are presented.
