The twisting and writhing during growth of single-cell filaments of Bacillus subtilis which lead to macrofiber formation was studied in both left- and right-handed forms of strains FJ7 and RHX. Filament bending, touching, and loop formation (folding)

Bacterial threads of Bacillus subtilis have been immersed in, and redrawn from, water of various pH values, in solutions of (NH4)2SO4 and NaCl of various concentrations, and in lysozyme solutions. The changes in the tensile strength, elastic modulus,

Experiments are described in which the tensile strength, the initial (Youngs') modulus, and other mechanical properties of the bacterial cell wall were obtained as functions of relative humidity (RH) in the range of 20 to 95%. These properties were d

The linear-density variations of simultaneously draw-textured filaments and conventionally false-twist-textured filaments are compared in terms of both wavelength spectrum and amplitude distribution. The evidence that these provide for a relation bet

Linear-density variation is suggested as the reason for improved dye-uptake in simultaneously draw-textured yarns. The origin of this variation is discussed, and it is shown how it follows from the statistical variation in filament draw ratio caused

The changes experienced by a yarn during its progress through the falst-twist-texturing system are examined. The relations involved, between twist, tension, and torque, and the process parameters, are shown to be those of a feedback system, and the d

A simplified model is considered for the prediction of tension ratio and torque generation. The extent to which variation in the angle of attack over a disc surface influences the results is discussed, and reasons are advanced for the torque generate

The yarn path is shown to be dominated by disc geometry and spacing rather than forces, Expressions are derived from which the angle of wrap and the angle of attack can be calculated for any profile and disc setting. Experimental verification is prov
