Figure 2: Formation of a polypeptide by reaction of amino acids. (R , R and R may be the same or different 1 2 3 side groups). These contaminants are removed during processing. Clean wool, together with other animal fibres, belongs to a group of proteins known as keratins. Unlike cotton and the majority of synthetic fibres, wool does not have a homogeneous structure. Wool fibres have highly com...

Manuscript describes producing keratin hydrolysate from sheep wool through two-stage technology whose principle consists in first having wool processed in an alkaline environment during the first stage, and then effecting hydrolysis in the second stage through the action of proteolytic enzyme. Experiments were planned in accordance with factor schemes of 23 types in which factors under study we...

An investigation into the moisture content in the fleece of Merino sheep was commenced after proposing the hypothesis that moisture and relative humidity were required at the skin surface for the survival of the 1st instar larvae and the initiation of a strike. A method for drying wool was developed which created a minimal disturbance to its normal constituents. It was shown that, in dry weathe...

The presence of dark fibres in white wool results in reduced profits or in cost recovery claims by wool processors and in reduced confidence in wool as an apparel fibre, which ultimately means lower prices for greasy wool. The allowances set by fabric manufacturers for contaminants are extremely small, typically no more than 3 contaminant faults per garment or per running metre of fabric, while...

Wool growth is derived directly from protein synthesis in the skin of sheep, and is affected by the nutritional status of the animals. The present experiment examined both protein synthesis in the skin and muscle and wool growth in Merino lambs differing in live weight, intake and dietary protein source. The experiment was a 2(3) factorial design: twenty-four 5-month-old lambs initially weighin...

In reviewing the Vicroria County History’s latest Wiltshire venture, John Chandler’s Codford, wool and war in Wiltshire, Pamela Slocombe takes a view that some of the references to sheep appear to be contradictory. I could not possibly comment on a disagreement between such local titans. But in devoting some attention in recent years to topics that involve sheep and cloth – floated water meadow...
