Effects of skirting on yield, fineness, and value of wool from fine-wool range ewes

Journal of Animal Science, 1992
Eighty-one mixed-age (2 to 8 yr old) Rambouillet ewes (58.5 kg, SD 5.9 kg) were randomly assigned to three treatment groups that contained similar numbers to study the effects of wool skirting on clean yield, fiber diameter, and prices received for fine wool. The sheep were managed as a single flock on an experimental ranch close to Barnhart, TX during

43—THE YIELD-TESTING OF WOOL BY REFLECTANCE SPECTROSCOPY

The Journal of The Textile Institute, 1978
Results are presented of the measurement of diffuse reflectance in the near-infra-red and visible regions, and it is shown that a new method of yield-testing of wool by reflectance spectroscopy in the two regions is available. The method gives a measure of the concentration of the components in washed wool. It is demonstrated that measurements obtained

17—THE PREDICTION OF THE COMMERCIAL CARBONIZING YIELD OF WOOL

The Journal of The Textile Institute, 1977
An investigation is reported in which the core-test yield was compared with the achieved mill yield for 90 commercial batches of Australian wool. Eight Australian mills participated in the trial. It was found that the wool base of the greasy wool (B g%) was directly proportional to the achieved mill yield. The carbonizing loss, which was on the average

28—THE PRECISION OF YIELD-TESTING OF GREASY WOOL

The Journal of The Textile Institute, 1975
For the assessment of the precision of measurement of wool base on auction lots of greasy wool, there are data available on the variability (i) of core-sampling, (ii) between laboratories, and (iii) between sub-samples (within a laboratory) with wool base as a variate.

Factors affecting wool scouring performance, yield and colour measurements of Western Australian fleece wools

Australian Journal of Experimental Agriculture, 2006
A benchtop scouring procedure was used to evaluate the ability of conventional detergent scouring systems to adequately clean fleece samples from a selection of Western Australian Merino wools. Sixteen fleeces were selected from the Western Australian Department of Agriculture resource flocks, covering a wide range in yield (49.2 to 77.5%), wax (7.3 ...

8—YIELD-TESTING OF GREASY-WOOL CORE SAMPLES: PART II: A FAST, MECHANICAL METHOD FOR THE DETERMINATION OF WOOL AND VEGETABLE-MATTER COMPONENTS IN SCOURED WOOL

Journal of the Textile Institute, 1971
The principle and basic design of a fast machine for the determination of wool and vegetable-matter components in scoured wool are described.

2—THE EFFECT OF DRYING FOR A YIELD TEST ON THE COLOUR OF WOOL

The Journal of The Textile Institute, 1984
Wool samples from a yield test on greasy wool are liable to be slightly discoloured by the specified drying procedure at 105°C. The downward bias in the measured colour values is both variable and, usually, unknown. Such samples are therefore unsuitable for colour-measurement purposes unless an unknown and variable bias can be tolerated.

High yield preparation of keratin powder from wool fiber

Fibers and Polymers, 2012
A descaling and oxidation pretreatment was employed to maximize the yield of cortical cells in the disintegration process of wool fiber. The results indicated that the productivity of intact cortical cells was greatly increased by moderate oxidation pretreatment in 1.6 % per-acetic acid within 2 h, but the yield would be decreased by further oxidation ...

The Prediction of the Yield of Wool by Near-Infrared ReHectance Spectroscopy

Textile Research Journal, 1981
The prediction of wool base of greasy wool in the form of miniature cores from digitized near-infrared reflectance spectra is demonstrated. This secondary calibra tion method combines measurements of reflectance at several wavelengths in a multiple linear regression equation for a prediction of wool base.

WOOL YIELD IN SOUTH INDIAN SHEEP

Madras Agricultural Journal, 1930
The economic aspects of rearing sheep as a side industry in Southern India have already been published in the Journal of the Textile Institute, Vol. 19 of 1928, article 5 (a). The experiences and facts gained during the last few years of sheep rearing in Hosur compared with the local practices in South India have now made clear that something more can ...
