The interaction and the durability to laundering of a cationic β-cyclodextrin derivative applied to Tencel were examined by x-ray photoelectron spectroscopy (XPS). The N1(s) XPS spectra of the cationic β-cyclodextrin treated substrates revealed the presence of the applied finish on the fibre surface and that the durability of the applied finish to hand-wash was good. However, the cationic β-cyclodextrin derivative showed poor durability to the ISO CO6/C2S wash protocol.

The tourist sector in Mauritius is aiming at welcoming 2 million tourists by the year 2015 and coming up with creative ideas and products branded with 'Made in Mauritius' to boost the country's craft sector. This project looks into the manufacture of paper-yarn. Different types of paper were cut into ribbons of varying widths and converted into yarn by two methods: twisting and folding. The folds were made along the axis of a ribbon while twisting required prior moistening and was carried out on a modified yarn-twist measuring device. The relationship between the number of folds/twists and the strength of the resulting paper yarn was investigated. Yarn of high quality can be obtained by twisting ribbons of relatively smaller widths or folding relatively wider ribbons. The yarn can be used for manufacturing craft products.

This paper has investigated the porosity of knitted fabrics using digital imaging techniques. A number of different methods have been proposed to determine the porosity of knitted fabrics, which include digital imaging, geometrical modeling, and air permeability. Digital imaging is an adequate technique to determine the porosity of high-porosity fabrics. In this work, eight types of knitted structures with eight different stitch lengths were produced on a flat-bed knitting machine. Porosity was determined using digital imaging techniques based on the method of threshold and pixel count, using a computer program developed for this work.
