Investigation of a wool measurement device for determining the mean diameter of a sample consisting of multiple wool fibresSpangenberg, Dirk-Mathys 03 1900 (has links)
Thesis (MScEng)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: In the wool trade the mean diameter of wool is a primary indicator of wool quality.
It is currently standard practice for a wool grower to send samples to a laboratory
for classification before and after shearing. The devices used to make
measurements on samples are often big and bulky and sensitive to the environment,
thus they are not ideally suited for on site testing. A brief discussion of
the industry is given with background information on existing devices as well as
information about organic fibres in general.
We test an experimental device which has the potential to be robust and compact
based on the Fourier optical principle. Two initial designs are considered
and the transmission design is further developed into a working system. The
working system is evaluated in a sample measurement experiment. In our sample
measurement experimentwe determine the mean diameter of a set of samples
which has been analysed by an external testing body such that the measurements
could be compared. / AFRIKAANSE OPSOMMING: In diewol bedryfword die gemiddelde diameter vanwol as ’n primêre kwaliteitindeks
gebruik. Dit is tans gebruiklik om wol monsters na ’n laboratorium te stuur
vir klassifikasie voor en na die skape geskeer word. Die toestel wat gebruik word
om die wol monsters te klassifiseer is geneig om groot, lomp en sensitief vir die
omgewing te wees en is sodoende nie ideaal vir veld gebruik nie. ’n Kort uitleg
van die industrie word gegee tesame met agtergrond inligting van bestaande
toestelle asook agtergrond oor organiese vesels in die algemeen.
Ons toets ’n eksperimentele toestel wat potensieel kompak en aanpasbaar kan
wees en gebaseer is op die Fourier optiese prinsiep. Twee aanvanklike ontwerpe
word oorweeg en eindelik word die transmissie ontwerp verder ontwikkel tot ’n
werkende sisteem. Die sisteem word geëvalueer in ’n monster meting eksperiment.
In die monster meting eksperiment bepaal ons die gemiddelde diameter
van ’n stel monsters waarvan die gemiddelde diameter deur ’n eksterne liggaam
bepaal is om sodoende die metings te kan vergelyk.

Economics of Wool Marketing in UtahBerry, E. Jay 01 May 1961 (has links)
Since the beginning of history the wool of sheep has been used by the human race. Its chief use has been and still is for clothing. Also, it is widely used for blankets, upholstery, carpets, and numerous other products.
The wool industry is important to the state of Utah, which was the sixth largest producing state in the United States in 1958. Wool growers in Utah received approximately $7,897,000 in sales proceeds and government payments for wool sold during the 1958 marketing year (12).1

Wool Scouring Tests in UtahEsplin, Alma C. 01 May 1941 (has links)
Wool as it is shorn from the sheep, is known as grease wool. The first tep in the manufacturing of wool is scouring, or removal of all grease and foreign matter. Within any given grade, as determined by length of staple and fineness of fiber, the yield of clean wool is the primary factor in determining the value of the original grease wool. The price of scoured or clean wool is multiplied by the percentage yield of clean wool to determine the value of the grease wool. Wool is graded and sorted before being scoured by the manufacturer. Large quantities are prepared for the scouring vate and the identity of the grower's clip is lost. Hence, the grower is entirely dependent upon the buyer's estimate of shrinkage or yield of clean wool, unless he obtains a representative sample of his clip and has it scoured to determine the yield. The object of the work reported in this thesis was to obtain information on the variability in yields of clean wool in Utah herds, and to add to work already done on methods of sampling and dtermining yields. Three methods have been used: (1) Whole fleece samples, (2) composite samples, and (3) side samples from individual sheep. Literature concerning each of these methods and other pertinent material is reviewed, and results obtained in Utah are presented.

The role of the extracellular matrix in wool follicle developmentMoore, Anthony G., University of Western Sydney, School of Science January 1999 (has links)
Molecular and behavioural characterisation of ovine dermal papilla cells performed in this study indicate they synthesise a highly specialised extracellular matrix (ECM). This is conserved between different species and distinguishes papilla cells from dermal fibroblasts with which they have a common origin. The composition of the dermal papilla ECM is temporally and spatially regulated during wool follicle development. It was shown that the ECM associated with dermal papilla cells in foetal sheep skin becomes specialised in regard to chondroitin sulphate synthesis prior to the appearance of follicle primordia. Chrondroitin sulphate and fibronectin were present in the ECM of dermal papilla cells throughout follicle development and during fibre production. Cellular differentiation antigen 44 was present in the ECM od papilla cells exclusively during the formation of dermal papilla, while laminin was present in the dermal papilla ECM of fibre producing follicles only. Co-operation between chondroitin sulphate, fibronectin, and CD44 in regulating the agrregative and proliferative behaviour of papilla cells was demonstrated in culture. Finally, the inhibition of proteoglycan synthesis in newborn mouse skin was found to disrupt the growth of existing follicles and the generation of new ones. Together these findings demonstrate that chondroitin sulphate is intimately associated with the earliest interactions between epithelial and mesenchymal cells during the formation of follicle primordia. It is likely that the interactions specifically involve fibronectin and CD44, and possibly other ECM molecules which have he effect of regulating the behaviour of papilla cells / Doctor of Philosophy (PhD)
