Thesis Title: A Study ofDetennining Fabric Hand Using a Ring Pull-Through Method
Thesis Author: Heidi L. Steckert
Abstract: Fabric hand, one of the most significant properties of a fabric, is tested not only by manufacturers, but also by consumers prior to purchase. Over the years textile manufacturers have used several different methods to measure fabric hand. Prior to the development ofthe Kawabata Evaluation System of Fabric (KES-F) and the Fabric Assurance by Simple Testing Method (FAST), fabric hand was evaluated subjectively by touch and feel. Both the KES-F and FAST systems use precise instruments that help manufacturers evaluate a product and maintain a desired hand. While these instruments provide valuable information, both are time consuming and costly to run. Furthermore, data produced by the two methods are sometimes difficult to interpret. There have been several studies conducted focusing on ways of determining fabric hand using methods that are relatively simple, fast, and less costly than current methods. Kim and Slaten (1999) published a study that evaluated fabric hand using fabric drag force through a metal ring. A similar experimental approach was used for the research upon which this thesis is based. The effects of ring size, pull-through speed, and fabric characteristics were of interest in this research. An Instron tensile testing device was used to measure the force needed to pull a variety of fabrics through different rings at various speeds. Analysis of test results generated from this method was used to obtain quantitative estimates of fabric hand. The results obtained were compared to values generated for the same fabrics using the KES instruments and the subjective pairedcomparison analysis. The results indicated that the test method developed in this thesis was both reliable and valid for the measurement of hand for knit fabrics.
