A facile effective stirring aging at room temperature prior to conventional hydrothermal treatment was employed in the template-free synthesis of micro- and nano-crystalline sodalites with two different initial gel compositions. The effect of initial Si/Al molar ratio, NaOH concentration and stirring aging time were investigated on the morphology and particle size of the...
Commercial wool scouring instructions are introduced mainly by technological and chemical manufacturing companies. Most of the instructions are prepared according to the technical specifications of the most famous international wool brands with high level of production. Other types of wools are scoured based on mentioned instructions with minor corrections. Using commercial instructions in scou...
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...
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...
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...
BACKGROUND AND AIMS An error involving the reuse of the same ball of cotton wool in stopping blood flow after venous blood collection from five antenatal women prompted further investigation and follow-up studies to rule out nosocomially-acquired blood borne viruses. METHODS The five women were screened for antibodies to the human immunodeficiency virus (HIV), hepatitis C virus (HCV) and hepa...
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...
