摘要： A wool or the like fiber scour including at least one of the following, (a) scouring process wherein the fiber is subjected to an acid extraction process to remove absorbed iron, and by to greatly improve the brightness (Y tristimulus value) of the wool; (b) a scouring process wherein a bleaching process is carried out part way through the wet process following by dying, rewriting and chemical reduction, therefore stabilising the bleached color to prevent subsequent reversion in the dyebath; or (c) a scouring process wherein scoured clean fiber is dried and dusted, and then reimmersed in liquors containing detergents and dispersants, thereby effectively removing extra amounts of residual dirt. The scour produces an improved quality of fibres.

摘要： A process for the preparation of soluble proteins of high molecular weight with little or no damage to the structural integrity of the proteins. The process is economically and environmentally acceptable by virtue of the cost of reagents that are used, and the recycling of some of those reagents, and is suitable for the production of soluble proteins on a large scale. The process includes a first stage using oxidative sulfitolysis followed by a second stage using mild conditions to extract the soluble protein. In the case of wool as the protein source the process leads to the production of soluble keratin proteins fractionated into the classes S-sulfonated keratin intermediate filament proteins and S-sulfonated keratin high sulfur proteins.
