    Description / Table of Contents: Abstract Measurements of the equatorial X-ray small-angle scattering are reported for 9 polyacrylnitrile fibers. They are evaluated according to Porod's theory. Data on void fraction and inner surface are obtained. With several samples, a Gumier-evaluation of the inner portion is possible, agreement is satisfactory. An attempt is made to interpret the results obtained with the help of a cyhndric model.
    Notes: Zusammenfassung Von 9 Polyacrylnitril-Fasern wird die diffuse äquatoriale Röntgenkleinwinkelstreuung gemessen und nach der Porod'schen Theorie ausgewertet, wobei Daten über den Hohlraumteil und die innere Oberfläche erhalten werden. Bei einigen Proben ist auch eine Guinier-Auswertung des Innenteils möglich; die Übereinstimmung ist gut. Es wird versucht, die Meßresultate anhand eines Zylindermodells zu interpretieren.

    Properties and structure of solvent-spun and viscose-type fibres in the swollen state (1993)
    Springer
    Colloid & polymer science 271 (1993), S. 460-468 
    Details
    ISSN: 1435-1536
    Keywords: Regenerated cellulose fibres ; swollen state ; crystallite orientation ; amorphous orientation ; fibrillar structure

    Notes: Abstract The conditioned and wet tensile strength resp. modulus of solvent-spun and viscose-type cellulose fibres was correlated with their crystallite and amorphous orientation factor. It was found that the extrapolation of these tensile properties to the maximum degree of orientation results in identical values of the tensile strength resp. modulus in the conditioned and water swollen state. Proportional to a decreasing orientation factor the loss of strength and modulus by swelling increases. Additionally, a positive correlation was found between the wet tensile strength resp. modulus and the intensity of the interference of the equatorial small-angle x-ray scattering measured in the swollen state. This interference is caused by the elementary fibrils. The intensity of this interference is a measure for the fibrillar character of the swollen fibre structure. The fibrillability of the fibres suspended in water correlates positively with the crystallite orientation factor.
