Abstract
The raising effect is closely related to the mechanical properties of raised fabrics. A principal component analysis has been made to totally assess the raising effect by using the mechanical properties of cotton fabrics, polyester spun fabrics, polyester filament fabrics and polyester 65%/cotton 35% blended fabrics.
The following results were obtained :
(1) Mechanical properties of cotton fabrics are grouped into following two components
i) tearing strength, weight, surface roughness, coefficient of friction, shearing and bending properties, and
ii) compressive properties, i.e., linearity of compressive curve, compressive work, compressive resilience and thickness.
(2) Mechanical properties of polyester filament fabrics and polyester/cotton blended fabrics are grouped into following three components.
i) tearing strength, weight, surface roughness, coefficient of friction, shearing properties and warp-wise bending properties,
ii) compressive properties, i.e., linearity of compressive curve, compressive work, compressive resilience and thickness, and
iii) weft-wise bending properties and surface roughness.
(3) An interaction of paper raising and washing improves a fabric hand to enchance the fabric softness and bulkiness.
