Features of formation indicators of Tsigai sheep wool quality

SummaryGarole is a breed of sheep reared in the Sunderban region of India and Bangladesh. The animals of this breed are adapted to the hot and humid coastal region and are often seen grazing in water. Garole are reared as mutton sheep. The value of their wool is grossly ignored and presently wasted. The raw wool obtained from this breed can be stored for a long time without any significant deterioration in quality, that might be attributed to the genetic tolerance of the breed towards fleece rot. The wool quality parameters of Garole sheep indicate that the wool is coarse but has an excellent felting property. The raisers of these sheep are economically challenged members of the society, and handicrafts produced from the wool can assist in the alleviation of poverty as well as provide an alternative livelihood. An organisation has taken steps in scientific sheep rearing in the region and has assisted in training members of the community in the production of rugs from the wool. The organisation is also providing assistance in marketing the products developed on behalf of the beneficiaries.

Sheep Wool

Currently, the need to ensure adequate quality of air inside the living space but also the thermal efficiency of buildings is pressing. This paper presents the capacity of sheep wool heat-insulating mattresses to simultaneously provide these needs, cumulatively analyzing efficiency indicators for thermal insulation and indicators of improving air quality. Thus, the values obtained for the coefficient of thermal conductivity, and its resistance to heat transfer, demonstrate the suitability of their use for thermal insulation. The results of the permeability to water vapor characteristics on the sorption/desorption of water, air, demonstrate the ability to control the humidity of the indoor air and the results on the reduction of the concentration of formaldehyde, demonstrating their contribution to the growth of the quality of the air, and to reduce the risk of disease in the population.

Sheep Wool

Poly(lactic acid) (PLA) was plasticized with maleinized linseed oil (MLO) and further reinforced with sheep wool fibers recovered from the dairy industry. The wool fibers were firstly functionalized with 1 and 2.5 phr of tris(2-methoxyethoxy)(vinyl) (TVS) silane coupling agent and were further used in 1, 5, and 10 phr to reinforce the PLA/MLO matrix. Then, the composite materials were processed by extrusion, followed by injection-molding processes. The mechanical, thermal, microstructural, and surface properties were assessed. While the addition of untreated wool fibers to the plasticized PLA/MLO matrix caused a general decrease in the mechanical properties, the TVS treatment was able to slightly compensate for such mechanical losses. Additionally, a shift in cold crystallization and a decrease in the degree of crystallization were observed due to the fiber silane modification. The microstructural analysis confirmed enhanced interaction between silane-modified fibers and the polymeric matrix. The inclusion of the fiber into the PLA/MLO matrix made the obtained material more hydrophobic, while the yellowish color of the material increased with the fiber content.
