As a result of electron-microscope studies on a selection of mammalian hairs, evidence is presented of the existence of an interlinking mechanism between the cortex and the cuticle. The occurrence of these interpenetrating devices is greater in vicuna hair and guanaco hair than in wool, and it is suggested that the mechanism of phagocytosis may be involved in their formation.

An account is given of some experiments made to elucidate the mechanism of lubrication when waxed worsted hosiery yarns run over a stationary solid surface. The effects on yarn friction of the amount of wax on the yarn, the yarn speed, the yarn moisture regain and the nature and temperature of the rubbing surface were studied, and, although several effects are at present unresolved, a general picture has been built up which fits most of the experimental results.

The effect of temperature on the stress–strain diagram and elastic recovery has been investigated for single fibres of Courtelle acrylic fibre. Most of the measurements were made in the wet state at temperatures of up to 80°C. Results show the presence of a glass-transition region at about 6O°C, and this has been confirmed by differential thermal analysis.

The significance of eight factors on the yield of polyacrylonitrile polymerized in situ within wool fibres by means of the ferrous-ion-hydrogen peroxide initiatory system has been investigated by a series of experiments. A statistical analysis of the results shows the yield to be significantly affected by the concentration of monomer, the time and temperature of polymerization, the pH and concentration of ferrous ions, and the concentration of hydrogen peroxide. In addition, it is shown tbat an interaction exists between the concentration of ferrous ions and the time of reaction. A formula is suggested to predict the polymer yield from the values of the six significant factors. The polymer yield may be predicted by the formula: Y = 7·54 × 10−4 {e0.004T [M]1.36 time0.7 pH0.3 [H2O2]0.34 [Fe++]0.34}.

An investigation is reported of the effect of variations in thread-spacing, type of yarn, weave, and fabric shrinkage in setting on the dry wrinkling of nylon shirting fabrics. Wrinkling of fabrics in laboratory tests and in wear was compared with fabric-constructional parameters. A highly significant correlation was established between the reciprocal of a tightness–crimp factor and wrinkling. The expression for this factor is a logical one, but no theory is presented in its support.
