Objective Sensibility Evaluation of the Acrylic Knitted Fabrics from Various Blended and Twisted Yarns

We performed the objective sensibility evaluation on knitted fabrics by the following procedures: setting acrylic fabrics with knitted fabrics as basis, knitted five kinds of blended spun yarns and four kinds of twisted filament yams made by different twisting methods(the amount and direction of twist) then, measuring mechanical properties in the use Kawabata Evaluation System, obtaining hand values and total hand values. The results are as follows: First, A(F)/W acrylic/wool spun knits obtain high scores in bending, compressing, shear properties, MMD, and thickness among five kinds of acrylic-blended knit fabrics. A(S)/W acrylic/wool blended knit represented prominent values at compressing properties and thickness and so wool-blended yams demonstrated superior characters comparing other blended yarns. To contrast, acrylic/rayon blended knits showed low scores in bending properties, shear properties and thickness, so that it affects to total hand values. On the one hand, among the four kinds of acrylic filament knitted fabrics, they do not exhibit any notable dynamic differences such as tensile properties of knitted fabrics by the twist number and direction of filament yarns, bending, shear, compressing properties, weight and thickness except surface properties. Second, fabrics showed the most high score at FUKURAMI (fullness and softness) among the hand values. A(S)/W acrylic/wool blended knits obtaining the lowest values at SAHRI (crispness) outrank at total hand values, so that it was the predominant knitted fabric in objective sensibility evaluation. In total hand values, five kinds of acrylic blended knits got a higher score than four kinds of acrylic filament knits, and the amount and direction of twist did not influence on total hand values among the four kinds of acrylic filaments.
