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.

The surface tension, dispersion- and polar-components of Nylon- 6 film dyed with acid, premetallized, chrome, direct and disperse dyes containing azoic groups have been determined by the Wu's equation.
The dyeing with milling, premetallized and chrome dyes with the high substantivity for nylon films decreased the polar component of the surface tension of a Nylon-6 film. By contrast, the dyeing with the levelling dye unchanged or rather increased the surface tension. Thus, it was concluded that the polar component decreased with increasing the substantivity while the dispersion component exhibited a slight increase if a film was dyed with an acid dye. The polar component increased if a Nylon-6 film was dyed with a tetrabasic direct dye or p-hydroxyazoic disperse dye.
The effect of a chemical structure of dyes and dyeing condition were also discussed.
