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.
