Mechanical parameters such as bending rigidity, thickness, compressibility, and coefficient of friction are measured by a sensory method for a series of plain and rib weft knitted structures made from cashmere and polyester textured yarns. The values estimated by the sensory method are found to be in fairly good agreement with the values measured on the KES system. The results of our work indicate that by using a standard and controlling the handling manner, sensory assessments can be as successfully quantified as instrumental measurements. However, detectable differences in each mechanical parameter vary with the sensory assessment, depending on the property being considered. The sensory measurement of fabric thickness yields the most consistent and accurate results. Other parameters such as the bending rigidity, compressibility, and coefficient of friction are also reasonably estimated. In addition, the effectiveness of the sensory measurements is also discussed in terms of knit construction and fiber type.Fabric mechanical properties are tested in two waysinstrumental and sensory. Objectively, they can be tested by instrumental systems such as KES and FAST. The objective tests are accurate, precise, and repeatable, but they are not always used for routine quality control in industry and in trading mainly because of their high cost. Therefore, sensory methods are still widely used for routine textile testing and are currently drawing much greater attention, though they are unstable, uncertain, and lack quantitativeness. In his study, &dquo;Subjective Textile Testing&dquo;, Slater [9] emphasized that sensory tests in which a standard comparison is available are usually more likely to correlate well with objective measures. Further, he suggested that for better subjective testing, theoretically sound methods such as ranking or paired comparison should be used because they are reliable and provide a measure of a specific parameter or property.Among sensory tests, sensory colorimetry is a wellestablished method. The use of a few color standards has been proven to be effective in sensory colorimetry. Whence, the proper method for measuring the mechanical properties should follow the same direction as colorimetry, that is, use of a standard.Studies on the quantitative measurements of mechanical properties by the sensory method are almost nonexistent, except for the method proposed by Matsuo et al.[8] for woven fabrics. Published reports about knitted fabrics are also nearly nonexistent. Therefore, the objective of our work is to quantitatively measure the mechanical parameters of knitted fabrics using a sensory test and to verify its effectiveness. In addition, we believe it will be interesting to find which properties of knits have objectivity in tactile assessments and how accurate those assessments are. ExperimentalFour sets of fabric samples were knitted and used in this work-cashmere plain weft, cashmere rib, PET plain weft, and PET rib. The fabrics of each set provided variations in cover factors and yarn thick...

“…The responses of consumers to fabrics have been known to be influenced by psychological factors such as affective impression, color preference, fashion, culture and their own way of evaluation (Winakor et al 1980;Hallos et al 1990;Kulkarni 1995). However, Hallos et al (1990) found that, in the evaluation of double-jersey knit fabrics, there was a close agreement between the ranking obtained from inexperienced judges who used a combination of sight and touch and the results obtained from an instrumental method for attributes of weight, thickness, fullness, smoothness (friction), extensibility and compressibility (hardness).…”

Many authors suggest evaluating the tactile hand properties of textiles in such a way that the sample cannot be seen, but this can be a cumbersome procedure. This study tested the effect of a strong visual attribute, color, on hand perception of fabrics in both descriptive and consumer studies. Panelists evaluated four cotton fabrics: poplin, flannel, knit and twill, each dyed five colors: white (no dye), dark blue, light blue, pink and yellow. In the descriptive study, minimal differences were found for only one color, yellow, in one fabric type, poplin, for four attributes: gritty, hand friction, fabric friction and softness. For the consumer study, only "brightness," a visual perception, and "harshness," which may be either visual or tactile, were different across fabrics from one color to another. Based on this study of color effects, there appears to be negligible impact of visual perception on tactile hand evaluation. This data would suggest there is little need to block the view of fabrics during hand evaluation in either descriptive or consumer studies. PRACTICAL APPLICATIONSData from this study suggest that the need to go to extraordinary means, such as blindfolding panelists, to block potential visual bias in tests of fabric 3 Corresponding

This study focuses on the mechanical properties of weft knits for outerwear as a function of knit structure and density and the relationships between hand, structure, and density. Eighteen weft knits are produced with six different structures (1 × 1 rib, half-cardigan rib, half-milano rib, interlock, single-pique, and crossmiss interlock) and three different densities (loose, medium, tight). The mechanical properties and hand values of the fabrics are measured using the KES-F method. Tensile properties increase for fabrics with a higher density, as do bending and shear properties. Compression values decrease somewhat as knit density increases but differences in compression values are not very large. Surface properties such as softness and smoothness increase with density. Specific findings for tensile properties reveal that the single-pique and the crossmiss interlock can not absorb external stress as much as the 1 × 1 rib and the interlock when stresses are applied in the course direction. Knits with tuck and miss stitches (halfcardigan rib, half-milano rib, single-pique, and crossmiss interlock) have better dimensional stability than fabrics with only knit stitches. Testing of primary hand values shows increased stiffness and fullness and softness and decreased smoothness as knit density increases. Total hand value increases with knit density. Double knits show higher total hand values than single knits. Half-milano rib and crossmiss interlock structures have the highest total hand values. Based on the tests results and an understanding of current market needs for dimensionally stable fabrics with a soft hand, we conclude that knit structures with combined miss and tuck stitches exhibit properties appropriate for outerwear fabrics for the winter season.
