This paper studied the wool and alpaca fibre curvature and its variation during the fibre processing. It revealed the effect of wool fibre crimp on the cohesion properties of alpaca and wool blended slivers. Different wool and alpaca tops were blended via a number of gillings, and the role of wool fibre curvature in alpaca/wool blend processing has also been investigated. During the wool fibre ...

Lambs wool production and qualities from the progeny of 2 Merino and 2 Damara rams mated to Merino ewes were compared. The crossbred lambs produced about half the amount of wool and had high fibre diameter variation and medullated fibre components. Merino lambs wool was contaminated with pigmented and medullated fibres apparently transferred from continual exposure to the Damara crossbred lambs...

In the production of mineral raw materials in cupolas, as a by-product and harmful product, significant amount cast iron (up to 3 % material) is formed and, rule, thrown into dumps. The article presents technical solutions that ensure separation melt iron. addition, describes results optimizing design ladders used for draining liquid metal from wool cupola transporting it. resulting ingots can ...

Sheep wool can be a waste products of sheep husbandry. Its safe utilization evokes several serious problems. Therefore, it was of interest to check out the usefulness of wool as a fertilizer and/or substrate. The aim of the experiments reported in this paper was to evaluate the effect of the washed sheep wool used as an amendment to peat-based growing substrate on growth and yield of tomato, sw...

This study aimed to reduce the holistic environmental impacts of insulation materials proposed for accommodation a marine cargo ship, and suggest optimal option cleaner ship production, using life cycle assessment. With commercial bulk carrier as case three major insulations were assessed, which wool-based material (mineral wool or glass wool), expanded polystyrene, polyurethane foam. The analy...

There are many missed biotechnological opportunities in the developmental countries. Wool quality improvement is one of them. This study is concerning with improving the wool quality using technical enzymes. White wool proves to be more susceptible to the enzymatic treatment than blackish brown wool. This proves that the enzymatic reaction is sensitive to the natural color differences between w...
