    Structure and properties of Nylon 6 and PET fibres: the effects of crystallite dimensions (1977)
    Springer
    Journal of materials science 12 (1977), S. 2310-2328

    Notes: Abstract Analyses of mechanical and diffusive properties of fibres are described indicating strong lateral interactions between the microfibrils. These results show that uniaxially oriented polymers must be analysed in terms of a model where the crystallites are imbedded in an “amorphous” matrix. The equations are derived for modulus, strength and coefficient of diffusion in terms of crystallite dimensions, and the results compared with the experimental data. These results contradict the predictions of the microfibrils model where the properties are independent of the crystallite dimensions but depend solely on the degree of crystallinity.

    Journal of Polymer Science: Polymer Chemistry Edition 18 (1980), S. 75-90 
    Details

    Topics: Chemistry and Pharmacology
    Notes: The synthesis of poly(ester carbonate) copolymers based on bisphenol A, terephthalic acid, and phosgene is reviewed, and a new synthetic route is described leading to polymers which are different from those obtained by methods described in the literature. The most important features of the new method are quantitative incorporation of the dicarboxylic acid into the polymer and absence of undersirable side reactions. Synthesis of the random copolymer in which the dicarboxylic acid and carbonic acid groups are present in about equal molar amounts is discussed. Solution properties, effects of M̄n and copolymer composition on Tg, sequence length distribution, the effect of ester interchange reactions on molecular weight distribution, and effects of monofunctional chain termination on molecular weight of the final product are also discussed.

    Interpretive nonlinear viscoelasticity: Dynamic properties of nylon 6, nylon 66, and nylon 12 fibers (1980)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Nonlinear response of nylon 6, nylon 66, and nylon 12 fibers to sinusoidal straining under relatively large strain amplitude is analyzed in terms of the changes in properties during the straining, i.e., the change in modulus, change in internal friction and change in structure which involves energy release or absorption in straining. Modulus generally increases with strain but it decreases with increase of strain amplitude, the effect of strain amplitude being largest with nylon 6 and smallest with nylon 66. Mechanical loss increase with the increase of strain amplitudes in nonlinear manner, and the magnitude of change is largest with nylon 66 and smallest with nylon 6. During the extension phase, structural change occurring in nylon 6 is predominantly an increase in order or orientation while that with nylon 66 is crack opening or cavitation. Various aspects of the experiments and analysis of the data are described in detail.

    Notes: The fiber spinning and heat treatments of spun fibers from thermotropic polyester carbonates are described. Thermotropic polyester carbonates derived from t-butylhydroquinone, methylhy-droquinone, diphenyl terephthalate, and diphenyl carbonate in the molar ratios of 50 : 50 : 55 : 45; 50 : 50 : 57.5 : 42.5; can be spun successfully, and after proper heat treatment, yield fibers with tenacity as high as 20 g/denier. Normally the best spinning temperature is 10-20°C above melting.

    Fiber-fiber coefficient of friction: Effects of modulus and tan δ (1979)

    Notes: The technologically important studies on rubber friction and wear give strong support to rubber friction being a viscoelastic phenomenon. However, the basic concepts and conclusions derived from such studies appear to have general validity. Fiber-to-fiber friction studies are carried out on a number of polymeric flaments with a view to establishing the relationships between fundamental mechanical properties such as modulus, tan δ, and the coefficient of friction. The relationship between these three quantities is expressed by an equation. The results show that with these fibers adhesive contribution to friction is negligible and that temperature and humidity variations in end uses have a much more important effect in frictional properties than changes in draw ratio, heat setting, and so on.

    Notes: Experimental measurements of the magnitude of air drag on the filament and the air velocity profile around the filament in the spinning and drawing down of a fiber filament in the surrounding of stagnant air are reported. The results are examined in comparison with the existing theoretical correlations that have been used in the studies of the spinning processes. The experimental values of the air drag are found to be larger than the values based on the existing correlations to such an extent that, in some cases of past studies, the air drag effect on the filament tension may have been underestimated.

    Notes: Experimental and simulation studies of optimization of the melt spinning process were carried out for nylon 6 fibers. The experiment and process simulation demonstrated that one criterion that can be applied in scaling up an optimized melt spinning process is to achieve the similar real time history of temperature and deformation rate in the spinway. Some aspects of the experiments and process simulation are discussed, together with the results of real time history analysis for a case of nylon 6 spinning.
