Hand- related properties of polyester-viscose and polyester-cotton ring and MJS yarn fabrics-Effects of fibre profile and finishing treatment

摘要

The hand- related properties of polyester-viscose and polyester-cotton ring and polyester-viscose MJS yarn fabrics have been studied using FAST evaluation system. Invariably, polyester-viscose MJS yarn fabrics have higher rigidity, higher extensibility and enhanced formability but display lower shear rigidity than ring-spun yarn fabrics. The fibre profile and fibre-mix are important and critical to fabric formability and shear rigidity. When compared with the grey fabric, finished fabric compressibility and shear rigidity increase, while bending rigidity, extensibility and formability are markedly reduced. Nevertheless, polyester-cotton fabrics are more rigid, less extensible and provide higher shear rigidity and enhanced formability even for similar fibre profiles.
