Some wool follicle and crimp parameters in fine-wool Tasmanian merinos

Australian Journal of Agricultural Research, 1969
Samples of wool and skin taken from the same animals were observed in finewool Tasmanian Merinos. It was found that highly crimped wool is produced by small follicles, follicle size being measured by the length of the chord or of the arc. It was also found that in animals on a high level of nutrition, high wool growth rate is ...

Factors affecting Merino wool contamination in crossbreeding

Australian Journal of Experimental Agriculture, 2002
Fleeces of Merino ewes were tested to identify whether contaminant sheep fibres increased from Damara-ram mating alone, whether extent of colouration of the crossbred lamb coat, day of birth and number of lambs being reared affect transfer to the maternal fleece, and whether increased fleece bulk or shearing the ewes 3.5 months post-weaning ...

Interaction of Subtilisin-Type Protease with Merino Wool Fibers

1998
In order to understand the structural modifications caused by proteolytic enzymes on wool fibers, the interaction of subtilisin-type protease with Merino wool was studied by physical and physico-chemical techniques. Enhanced wool dye affinity and optical microscopy examination indicate increasing fiber damage as a function of enzyme action.

Surface Topography of Blank-Dyed Merino Wool

Textile Research Journal, 1981
Merino wool was blank-dyed in citric acid-phosphate buffer at pH 2.0, 4.5, and 8.0, at the boil, for periods of up to five hours. The treatment dissolved significant quantities of protein material from the wool and altered the fiber cuticle surface. Scanning electron microscope studies showed that modification of the cuticle cell surface occurred at ...

The Sustainable Colouration of Merino Wool Yarns with Herbs

Journal of Textile Engineering and Fashion Technology, 2021
The Textile industry is the second largest polluter in the world. The European green deal has placed the textile industry at the top priority for establishing sustainability standards for the global benefit to the environment and human health alike.

Characteristics of the Protein Contaminant Layer on Merino Wool

Textile Research Journal, 1984
Some characteristics of the protein contaminant layer (PCL) extracted from a typical Australian Merino wool have been studied. The PCL was separated into water-extractable and particulate fractions, the overall yield being 4.1 %, of which 45% was soluble in water.

Reduction in wool follicles prior to birth in Merino sheep

Reproduction, Fertility and Development, 2000
This study was undertaken to identify whether all secondary follicles that are initiated are present at birth in the Merino fetus, and if not, when does net initiation of secondary follicles cease. Skin was sampled from fetal lambs at 36, 26 and 16 days before the estimated date of parturition and from lambs at birth and 2, 4, 6, 8 and 13 weeks after ...

Is merino wool disappearing in Portugal: Merino Beira Baixa case

2002
In Portugal we are facing a fast decrease in the production of good quality wool. This situation can be seen from a qualitative and quantitative point of view by looking at the most extreme situation, which involves almost the extinction of a Merino breed - Merino Beira Baixa (MBB)- due to its inability to produce high milk quantities when subjected to

Valuing quality attributes of Australian merino wool

2014
We measure the relationship between clean prices of individual lots of wool sold at auction and a range of characteristics of the raw wool. Based on the data for 111,440 fleece lots sold in the 2008–2009 auction season, five hedonic models are estimated to determine the premiums and discounts associated with each wool characteristic in five micron ...

Wool fibre shedding in some Merino sheep

Australian Journal of Agricultural Research, 1967
Four sheep were investigated by monthly skin sampling for 3 years in Australia, and four sheep by quarterly sampling for 3 years in Scotland. Those in Australia had shedding in 30–50% of the samples while those in Scotland had shedding in only 15–30%, but in both the incidence of brush ends was less than 1%.
