Effect of atmospheric plasma treatment on pad-dyeing of natural dyes on wool

Plasma treatment is an emerging surface modification technique that alters dye uptake of wool without using chemicals or water for pre-treatment. Padding is an established continuous dyeing technique known for its efficient use of water, time and energy. This study combined these two techniques for colouration of wool fabric using two natural dyes derived from the Acacia plant family. The investigation focused on the effects of plasma treatment and obtaining unique patterning effects. Helium (100%) and a mixture of helium and nitrogen (95%/5%) were used as the plasma gases under atmospheric conditions. Plasma treated wool fabric was padded with the above natural dyes. Copper sulphate and ferrous sulphate were applied on the dyed fabric as mordant yielding neutral shades of beige and grey respectively. Up to a 30% enhancement of dye adsorption on plasma treated wool substrate was observed as compared to untreated sample for both gases used. This higher adsorption indicates the hydrophilic character of the natural dyes used. Key performance parameters such as fastness to washing, rubbing and light were tested and found to be satisfactory. A single process tone-on-tone pattern was achieved by controlling the plasma exposure of treated area. This study concluded that a merger of natural dyes with modern plasma treatment and padding techniques for wool colouration was feasible.

Stanley Melbourne Bruce in London, 1938-41

This article examines Stanley Melbourne Bruce's role as Australian high commissioner in London during the approach to the Second World War and the European War from 1939 to 1941. It argues that Bruce in this period was an influential high commissioner who strongly influenced Australian foreign policy and exercised some influence, albeit with limitations, on the British government. After 1933, Bruce had transformed the office of Australian high commissioner in London from a largely commercial position into one with real diplomatic influence. In the approach to war, Bruce tended to bolster the policy of appeasement on which the Chamberlain government was already decided and in the Phoney War his cautious arguments contributed to the delay of the Allied intervention in Norway. With the accession of Winston Churchill to the prime ministership in May 1940, Bruce lost some of the influence he had had with Neville Chamberlain and he was on the losing side of the argument inside the British Cabinet about the possibility of a negotiated peace in May–June 1940. Despite the limitations of his personal relationship with Churchill, he was nonetheless an influential voice with other British ministers and senior officials and with the US ambassador in London and key members of the Roosevelt administration. This equipped him to play an effective part in the emerging Anglo-American alliance and issues of post-war international reconstruction.

‘Stanley Schupak doesn’t live here anymore’: un/becoming transsexual and coming home in Duncan Tucker’s Transamerica

This article analyses the representation of male-to-female transsexuality as represented in Duncan Tucker's film Transamerica (2005). Using a combination of transgender theory and textual analysis this article argues that there is a normativising agenda in this film that makes transsexuality pallatable for non-transgender (or cisgender) audiences by aligning it with idealised (and conservative) conventions in Western culture for women, those of motherhood, heterosexuality, and family-centricity.
