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 ...

There is a growing need in the textile industry for more economical and environmentally responsible approaches to improve the scouring process as part of the pretreatment of cotton fabric. Enzymatic methods using pectin-degrading enzymes are potentially valuable candidates in this effort because they could reduce the amount of toxic alkaline chemicals currently used. Using high throughput scree...

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...

An experimental approach was carried out to study the time development and extension of scouring around a circular pier protected by a collar. The experiments included the study of scouring around an unprotected pier as well as the pier protected with collars located at different levels. Width of collars was 3 times the pier diameter. It was found that with collars, though the scour depth and t...

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...

Local scouring in the downstream of hydraulic structures is one of the important issues in river and hydraulic engineering, which involves a lot of costs every year, so the prediction of the rate of scour is important in hydraulic design. Side weirs are the most important of hydraulic structures that are used in passing flow. This study investigate the scouring due to falling jet from side weir...

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...

There are varieties of factors which can affect wool (macro and micro elements of wool) in sheep directly or indirectly. Genetic and environmental factors are major factors influencing wool quality and quantity. There are some bacterial, viral, fungal and espically parasitic diseases which also affect the wool. Other factors are exogenous chemicals, hormones, weather and photo period. In the pr...

Fiber diameter is a useful indicator of wool traits and it is the main determinant of wool quality and value. A comparative study was conducted to analyze the abundance and expression of 13 candidate genes using expression profile microarray analysis and to identify novel molecular markers associated with wool traits to provide a molecular basis for improving wool quality in sheep. Genes associ...

The textile industry uses different fibers obtained from various animals, of which the wool from domesticated sheep Ovis aries is commercially the most important. Dyeing is one of the most important finishing procedures of wool processing. It almost invariably involves absorption of water-soluble colorants from aqueous solutions by the fibers. Diffusion is the process by which the colorant mole...
