Influences of Fundamental Characteristics of Weft Yarns and Decatizing Treatment on Mechanical Properties of Silk Necktie Fabrics

Abstract

The influences of the fundamental characteristics of weft yarns and decatizing treatment on the mechanical properties of silk necktie fabrics were investigated. The silk necktie fabrics with 63 denier weft yarns (manufactured by twisting 3 silk yarns of 21 denier) in doubles showed higher values of the shear and bending rigidity as well as their hysteresis as compared with the fabrics with 126 denier weft yarns (manufactured by twisting 6 silk yarns of 21 denier) in singles. For the fabrics with methacrylamide grafted 126 denier weft yarns, the shear rigidity and its hysteresis decreased, but the bending rigidity of satin fabrics increased. The decatizing treatment was effective to reduce the shear rigidity and its hysteresis.
