A Comprehensive Critique on Wool Grease Extraction, Properties and Applications

Ever since the Stone Age, humans have preferred natural products and materials for better health and comfortability. Wool and natural silk have been used in the textile clothing thousands of years ago. The performance and appearance attributes of wool and silk make them superior for many applications. On the other hand, the textile industries are technically, economically, socially, and environmentally related to some of the sustainable development goals (SDGs) of the United Nations Agenda 2030. For instance, the item number 12 in the SDGs aims to ensure sustainable consumption and production pattern. This necessitates proper utilization of all natural products as well as recycling and utilization of any waste thereof.This article review deals with retrieval of wastes or by-products during wet processing of proteinic fibres; namely wool and silk. Different ways of proper utilization of the retrieved materials will be proposed. Specifically, this review article will focus mainly on three main by-products; namely keratinous materials, wool wax, and sericin. State of the art and future prospects for the utilization of these materials in the production of textile auxiliaries; Viz. softeners, binders, and flame-retardants, were discussed.

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.

“…Wool wax in its crude form is dark, highly viscous and greasy paste. So, the crude wool wax must be refined before it can be used for different fields (El-Sayed et al, 2018). The refined wool wax is generally known as lanolin.…”

Two forms of pollutants are usually discharged from scouring of wool fleece; namely the effluent liquid phase and the solid phase. These phases comprise a significant quantity of wool wax which would be a suitable candidate for valuable products and applications. This work is devoted to extraction, recovery, and characterization of lanolin from wool fleece from different sheep breeds to assign possible ways for its utilization in the textile field. The results show that the amount of wool wax extracted from coarse wool fleece as well as its chemical composition and physical properties are almost similar to those extracted from other finer wool fleece. The aim of this work is further devoted to separation and characterization of fatty acids (FAs) from the extracted wool wax. The separated wool FAs were esterified with poly ethylene glycol (PEG) to obtain a condensate which was utilized as a nonionic softener for wool. The alteration in morphology of the coated wool fabric was assessed using scanning electron microscopy. The results revealed that the WFA/PEG-coated fabrics exhibit reduced surface roughness and improved resistance to felting shrinkage during mechanical agitation.
