Wool has been shown to absorb sulphuric acid from the vapour phase. The rate of absorption increases with acid concentrations of up to 99·5% by weight and decreases with the pressure of inert molecules present in the system. Uptakes in excess of 200% on the original weight of wool have been observed at temperatures close to ambient. The observed weight increase due to absorbed acid is dependent on exposure time because degradation of the wool results in loss of material. A proposed mechanism for the absorption of H2SO4, molecules includes steps involving the effect of inert-gas molecules adsorbed onto the fibre surface, immobilization of absorbed acid by chemicai reaction with the wool, and barrier effects due to packing densities and the formation of a boundary layer in the presence of appreciable pressures of inert-gas molecules. The presence of absorbed H2SO4 has been shown to modify the subsequent water-sorption properties of the wool owing to reaction of acid with hydrophilic groups and also because ...

A mathematical analysis is given to determine how, in the absence of fibre breakage, fibres from a sliver of straight, parallel fibres are selected for length by the Noble comb and separated into large-circle sliver, small-circle sliver, and noil. Simple assumptions are made concerning fibre-end density and relative holding power of the circles. A theory of fibre selection is developed to predict how the selection of fibres changes with the various parameters of the comb.

An account is given of an investigation of the relations between the tensile properties of stretch fabrics, in which the stretch component was nylon 6.6 false-twist crimped yarn, and the resistance to bagging of trews in wear. It is shown that the fabric extension at a given load and the non-recoverable extension from a given load, measured under specified conditions, correctly predicted resistance to bagging in wear. The importance of garment style and fabric construction is demonstrated.

The action of soap and alkali and of alkali alone in removing dirt from naturally soiled fibres has been studied microscopically. The concentrations usually employed were those commonly used in laundering. Cinematography facilitated the observation of some of the effects. The most common methods of fatty-dirt removal involved emulsification and rolling up: complex-formation was less common. Most of the phenomena originally observed with artificial systems also occurred with these natural ones.
