    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.

    Description / Table of Contents: Vier Proben von Poly(oxyethylen) gelöst in Wasser wurden rheologisch untersucht. Fließkurven für verschiedene Molmassen und Konzentrationen wurden erhalten. Aus den no -Werten wurden die Netzwerk-Segmente, das scheinbare Fadenelement und die Durchdringungshemmung ermittelt. Das Polymere bildet in Wasser Verhängungsnetzwerke mit behinderter Durchdringung.
    Notes: Four samples of poly(oxyethylene) dissolved in water have been studied rheologically. Flow curves have been obtained for different molecular mass and concentration. From no the mass of network strand, the apparent chain element and the penetration hindrance have been obtained. The polymer turns out to form in water entanglement network solutions with somewhat hindered penetration.

    Changes of structure and morphology of regenerated cellulose caused by acid and enzymatic hydrolysisDedicated to Doz. Dr. Erich Treiber on the occasion of his 70th birthday. (1990)

    Notes: The kinetics of the enzymatic hydrolysis of regenerated cellulose fibers before and after acid prehydrolysis has been investigated. This pretreatment changes the kinetics from a monophasic to a biphasic first order reaction. Prolonged acid prehydrolysis increases the proportion of the enzymatically easily hydrolyzable cellulose form. The kinetics were correlated with corresponding changes of the degree of polymerization, crystallinity and crystallite size.

    Description / Table of Contents: Die Auswertung der Langperioden und Kristallitlängen originaler sowie vorbehandelter, lösungsersponnener Cellulosefasern ergab, daß diese in Richtung der Faserachse zu ca. 90% aus kristalliner Cellulose bestehen. Bei hochnaßfesten Viskosefasern beträgt dieser Anteil nur 50-60%. Die Intensität der Langperiode der lösungsersponnenen Fasern ist niedriger als die der hochnaßfesten Viskosefasern entsprechend einer geringeren Differenz zwischen ihrem kristallinen und amorphen Orientierungsfaktor. Zwischen dieser Differenz und der Langperioden-Intensität besteht eine signifikante Korrelation.
    Notes: The evaluation of the long periods and crystallite lengths of original and pretreated solvent spun cellulose fibres revealed that they consist of about 90% crystalline cellulose in the direction of the fibre axis. In the case of high wet modulus viscose fibres this percentage is only 50-60%. The intensity of the long period of solvent spun fibres is lower than that of the high wet modulus viscose fibres corresponding to a smaller difference between their crystalline and amorphous orientation factors. There is existing a significant correlation between this difference and the intensity of the long period.
