“…The re-combed and shrink-resist treated wool roving was utilized for preparing multiples of staple yarns (AgResearch Ltd.), the specifications of which are presented in Table 1. The physical and mechanical properties of wool fibers are influenced by their moisture regain and temperature, 24 which relate to the ambient temperature and relative humidity. In order to influence the performance of wool fibers during yarn formation, as well as the properties of resultant yarns, all roving were conditioned before spinning for about 24 h at the standard environment of 20AE2 C and 65AE2% relative humidity.…”

Hairiness is a prominent property of staple yarns, but the existing evaluation parameters mainly describe the fiber ends already protruding out of yarn bodies. The potential fiber ends in yarns also play a crucial role in the performance of yarns in the subsequent processes and the resultant fabric quality. In our previous studies, maximum hairiness and its theoretical model have been proposed, which indicate the maximum fiber ends of a staple yarn having the potential to protrude out of yarn bodies and become hairy. On this basis, the relative hairiness index (RHI) is developed in this study to evaluate the fiber end tucking and securities of yarns. This index is treated as a ratio of the measured hairiness of sample yarns and the maximum hairiness of ring yarns in the same twist level and yarn count. A lower RHI indicates more fiber ends being tucked into yarn bodies, and a slower increment of the RHI with the increasing winding times represents more stable securities of fiber ends in yarns. The experimental results demonstrate that the RHI can directly reveal the effectiveness of different spinning parameters and methods in tucking and securing fiber ends; also, the changes of the RHI with increasing winding times visually present the stableness of fiber ends in various yarns experiencing abrasion, as well as predict the possibility of the potential fiber ends being pulled out to form hairiness during successive processes. The proposed RHI, therefore, provides a significant reference for the spinning process design and yarn quality control.

“…Due to this, it has a high level of thermal insulation. Wool is the fibrous coating from sheep (Figure 2), is the most important animal fiber used by the textile industry (Rippon et al, 2016). Wool absorbs up to 40% moisture and stays dry.…”

The relevance of this article is related to the Kyrgyz people's skills in using natural wool for the treatment of various diseases in nomadic life. As a source of natural resources, sheep and goat wool with mineral substances were used. Sheep's wool is the main source of wool in the Kyrgyz people's nomadic life. Sheep wool is also widely used in traditional Kyrgyz medicine. The Kyrgyz people knew from their nomadic experience, and scientists determined that the physical properties and chemical composition of wool had a very positive effect on human health. Theoretical methods were based on the scholarly and scientific article's analysis in historical aspect. Empirical method is a popular and important research method in ethnology, which was implemented through surveys, participation in the process, observations and interviews of informants who are familiar with traditional medicine and wool products' health effects. Research results were obtained using the comparative-historical method through a scientific cycle and a hypothesis. The article describes how the Kyrgyz people were able to work in a variety of ways in nomadic life, as well as promoting good health.

“…As such, there has been very limited work from an Irish perspective on the amount, type, quality or chemical composition of sheep wool. The global production systems for sheep considerably vary, especially across Europe, due primarily to differences in environmental and climatic conditions, breed types, soil and forage types, animal nutrition, and farm management practices [3][4][5]. Consequentially, research outputs and information on sheep wool composition from one country, breed or system may not be relevant or applicable in others.…”

The Potential for Hydrolysed Sheep Wool as a Sustainable Source of Fertiliser for Irish Agriculture

2021

Suppressed wool prices in Ireland over the last number of years has led to situations where the cost of shearing animals is greater than the wools’ value, leading to net losses per animal for farmers. Populations of sheep in Ireland and nutrient values of wool from literature sources were used to determine the quantity of nutrients that could be produced on an annual basis using hydrolysis techniques. Results of this study suggest that up to 15.8% of the nitrogen required to produce Ireland’s cereal crops can be met annually using hydrolysed sheep wool in an economically feasible manner along with considerable amounts of sulphur, zinc, and copper. Most of the cost associated with the process is the purchasing of wool from farmers at an economically favourable level for farmers. Based on the spatial distribution of these animals, the town of Athlone is the most suitable location for a processing facility.
