Sensorial Property Evaluation of Scoured Silk Fabrics Using Quad Analysis

Abstract

The importance and usefulness of a subjective evaluation of the sensorial properties of scoured silk fabrics is discussed. Silk fabric was treated with 12 different scouring rates and the scoured fabrics were used as specimens. Seven trained subjects, using paired comparisons, evaluated seven subjective sensorial properties. A quad experimental design was adopted for a more effective and reliable evaluation. Objective sensorial properties were assessed by using the Kawabata Evaluation System (KES), and objective measurement and subjective evaluation of sensorial properties were correlated to the scouring rate. The results show that subjects did not recognize the differences in smoothness of the samples, even though the objective measurements demonstrated differences between them. Softness or stiffness, drapability, and luster were closely correlated to the scouring rate, implying that these subjective properties can be effectively manipulated by the scouring process of silk fabrics.

Odor Retention on Apparel Fabrics: Development of Test Methods for Sensory Detection

“…Previously the QA method had been applied to visual and tactile properties of fabrics [10,16], but not to detection of odor. A benefit of the QA test method is that it reduces the number of pairs required for assessment compared to the traditional paired-comparison test [10].…”

“…Many of these factors do not constrain sensory evaluation of other fabric properties (e.g. tactile) [16]. Unfortunately, this adaptation to the design precluded every assessor being exposed to every pair.…”

“…A balanced incomplete-block design, the quad analysis method does not employ all possible combinations of quads to be analyzed, and thus is more efficient than a multiple pairedcomparison design in which all pairs are considered. The quad analysis technique has been applied in visual grading of carpets [10] and handle properties of silk fabrics [16]. However, this technique seems not yet to have been applied to odor.…”

Social, Economic and Cultural Dimensions of Sensory Evaluation and Its Possible Applications to the Various Disciplines of Home Economics in the Philippines

“…Quality Control of Textiles. Sensory evaluation had been applied in the study of the quality of fabrics and textiles (Winakor et al 1980;Chollakup et al 2004;Kim et al 2005;Pense-Lheritier et al 2006;Strazdiene et al 2006). Likewise, comfort and other physiological effects of clothing or apparel/fabrics (Stuart et al 1989, Sweeney and Branson 1990, Barker 2002, Cardello et al 2003, Okabe and Kurokawa 2004 and effects of the design (Sohn 2003) had been measured using sensory analysis.…”

Development of a fabric classification system using drapability and tactile characteristics

“…A larger drape coefficient indicates a stiffer silhouette, while a smaller value means a drapery silhouette (Kenkare & May-Plumlee, 2005). Subjective measurements of drapability involve evaluators grade or ranking the tactile sensation felt in their hands, or comparing pairs of test items (Kim et al, 2005;Lee & Lim, 2014). However, objective evaluations of fabric drape characteristics can vary even with the same sample in repeated experiments, as they may not always produce the exact same shape, affecting the drape coefficient (Jeong, 1998).…”
