“…In recent times, the application of sulphur dyes to non‐cellulosic fibres such as silk, nylon and wool has been explored and reflects the importance and potential of these dyes. For example, with chamois leathers in sports garments, gloves and other personal wear, there has been increasing consumer demand for a broader range of colours as well as an evaluation of the use of water‐soluble sulphur dyes . The use of solubilised sulphur dyes for colouring chrome‐tanned leathers and tone‐in‐tone dyeing has also been reported recently…”

Sulphur-dyed cellulosic textiles are susceptible to washing powders containing activated peracid formulations resulting in obvious fading during repeated laundering.This study presents a novel one-bath/two-stage exhaust finishing process to improve the oxidative wash fastness of CI Leuco Sulphur Black 1-dyed cotton fabric. The effect of the combined Tinofix ECO and Bayprotect Cl after-treatment was to impart better colour fastness to oxidative International Organisation for Standardisation (ISO) 105 CO9 washing of the dyed cotton compared with those dyed fabrics aftertreated with Tinofix ECO alone. In addition, while the dyed fabrics rub and light fastness performances were unchanged by the after-treatments, some improvement in the tensile strength of the combined Tinofix ECO and Bayprotect Cl after-treated fabrics was observed.

The effect of alkaline pH on the association, dissociation, and denaturation of carmin, the high-molecular-weight protein from safflower seed was investigated in the pH range 7-12, using various biophysical techniques. The results indicate that the multimeric protein carmin dissociates at pH 8.0 where denaturation has not set in. The association-dissociation of the protein can be represented schematically as 11S in equilibrium 7S in equilibrium 4S----2S. Above pH 10, the protein undergoes simultaneous dissociation and denaturation. The denaturation process appears to be complete at approximately pH 12.5. The protein undergoes conformational change and covalent modifications and cleavage during the denaturation process. A reversibility study shows that the process of dissociation is reversible to a large extent, whereas denaturation appears to be irreversible. These results are discussed in terms of association-dissociation, denaturation and alkaline-catalyzed covalent modifications and cleavage of seed proteins.

1429Cucurbitin, a physicochemically typical oilseed storage prc~ tein from pumpkin and other cucurbits, was treated with 20% H202 for periods up to 36 h to determine the length of exposure needed to render it water-soluble. Maximum solubility was reached in 8 h from virtual insolubility and started decreasing after about 12 h. These results not only indicate that H202 was effective in rendering oilseed protein wate~soluble and can be used to prepare several ratios z of soluble-t~insoluble protein products, but also show the "' lengths of exposure needed to obtain the required solubilities, a_ KEY WORDS: Cucurbitaceae, cucurbitin, globulin, hydrogen peroxide, oilseed, protein, protein solubility.
