The purpose of this investigation was to provide quantitative data showing the effect of oxidizing agents on wool as a basis for studying all processes in which wool is exposed to oxidation reactions. The work reported in this paper deals only with the effect of hydrogen peroxide. Data are presented showing the effects on wool of varying the concentration, temperature, and pH of the hydrogen pe...

Glass wool, hydrophilic cotton wool, non-electrically charged BIO-GEL P2 and common tissue paper columns were used to purify trypomastigotes from a mixed Trypanosoma cruzi population grown in axenic culture medium. With all these columns, highly purified (up to 98%) trypomastigote preparations were obtained. Trypomastigote yields from cotton wool, BIO-GEL P2 and common tissue paper columns were...

This study investigated the effects of Spirulina (Arthrospira plantensis) supplementation level, basal diet, sire breed, and sex on wool quality parameters in purebred and crossbred Merino lambs. A total of 48 lambs, over two consecutive years (n=24 per year), was randomly allocated into Spirulina supplementation level (CONTROL, LOW, MEDIUM, HIGH) groups and balanced by sire breed (Black Suffol...

Sheep from 4 Merino flocks, different in annual clean fleece production when grazed together, were given several nutritional treatments to compare the relationships of wool sulphur with nutrient intake, and with wool growth and plasma cystine. The sheep were selected from a finewool (Fl), a strong wool (S), and 2 medium-Peppin (MP6 and MPlO) flocks. The nutritional treatments varied intakes of ...

BACKGROUND Wool quality is one of the most important economic traits in sheep. The wool fiber is derived from specialized skin cells that are referred to as wool follicles. To understand the roles of microRNAs (miRNAs) in wool fiber growth, we detected the expression patterns of miRNAs in wool follicles at the anagen, catagen, and telogen stages from Tibetan sheep through Solexa sequencing. R...

In recent years, chitosan and its different derivatives have been extensively used in surface modification and functional finishing of textiles. In this study, wool yarns used in handmade carpet were treated with different concentrations of chitosan-poly (amidoamine) dendrimer hybrid (Ch-PAMAM) and characterized by scanning electron microscope (SEM), and their dyeing properties were investi...

The desmoglein 4 (DSG4) gene is a potential candidate in the search for genes that may affect wool traits, because of its function. This study aimed to screen for polymorphisms in partial exon 16 and 3ꞌUTR of the sheep desmoglein 4 DSG4 gene, and to test its possible association with wool length and crimp associated with fur. Overall, 326 sheep were scanned via single-strand conformational poly...

Wool fibres have been chemically modified by reduction I chlorination under acidic pH Ipre-swelling in conc. formic acid prior to their dyeing with indigenous reactive dyes of different molecular configurations to enhance the reactive dye uptake on wool fibre substrate. The pretreatment processes are inexpensive, less harmful and less time consuming as against the use of imported special wool r...
