An Integrated Approach to Analyzing the Nature of Multicomponent Fiber Blending

Abstract

This paper presents a detailed analysis of the nature of multicomponent fiber blending using an integrated analytical and experimental approach. This approach is based on classifying the blending phenomenon into four basic modes: structural blending, attribu tive blending, appearance blending, and interactive blending, Structural blending implies the extent of geometric allocations of different fiber segments within the structural boundaries of the fiber strand. This is analyzed using the so-called representation index, which determines the extent of a fiber component's representation in the blend. Attributive blending indicates the extent of the interaction of different fiber attributes within the characteristic boundaries of the fibrous assembly. This is analyzed on the basis of the extent of the linearity and additivity of the characteristics of blended fibers. In this regard. new analytical tools are introduced, including the blending matrix, blend profiles, and blending index. Appearance blending describes the extent of homogenization of a color's or component's apparent intensity in the fiber assembly. This is analyzed on the basis of color contrast in the blend, which is determined by the light intensity of different fiber components. Interactive blending implies the mechanical interaction of fibers within a component and of different fiber components during the blending process. This is determined by the propensity of blended fiber components to opening, measured by the energy required to achieve fiber cluster breakdown.
