“…Wet processing of wool includes, among others, all or some of the following operations depending on the customer demand: scouring, carbonization, milling, shrink-proofing, bleaching, coloration, moth-proofing, anti-pilling, anti-microbial, flame-proofing, and UV protection [6]. Many investigations have been conducted to improve the efficiency of these processes with cost-effective operations [7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

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.

“…Wool fibres’ quality is affected by the environment in which the sheep is raised and the amount of lipids present on the epicuticle surface. Processing of textile fibres, like wool, involves extensive wet treatments to improve their performance attributes including softness, anti-pilling and dimensional stability (Abou Taleb et al 2018 ; El-Newashy et al 2019 ; El-Sayed 2021 ; Kantouch et al 2011a ). These treatments bring about some environmental concerns such as increased chemical oxygen demand (COD) of the drained water as well as discharge of absorbable organo-halogens into the effluent (Abou Taleb et al 2020a ; El‐Sayed and El‐Khatib 2005 ; Mowafi et al 2018 ).…”

Wool has the tendency to turn into felt during agitation in washing machines. Thus, a benign non-polluting method for the production of machine-washable wool was developed herein. Initially, a proteolytic bacteria was isolated from hot region soil. The bacterial isolate was identified as Bacillus safensis FO-36bMZ836779 according to the 16S rRNA gene sequencing. Afterwards, the extracellular protease produced by this isolate was covalently immobilized in order to enhance its stability under non-ambient conditions which are usually adopted in industrial sectors like textile industries. Sericin, which is usually discharged into degumming effluent of natural silk, was utilized to prepare the immobilization carrier. Box–Behnken design was adopted in order to hone the preparation of the sericin–polyethylene–imine–glutaraldehyde activated agar carrier. The pH and temperature profiles of the free and immobilized proteases were compared. Later, wool fibres were bio-treated with both the free and the immobilized enzymes. The effect of process conditions on the resistance of the bio-finished wool to felting was investigated. The alteration in the fibre morphology was monitored using SEM. Amino acid analysis and alkali solubility tests were adopted to assign any change in the chemical structure of the bio-treated wool. The influence of bio-treatment of wool on its inherent properties was assigned. Results revealed that bio-treatment of wool with the said enzyme led to production of machine-washable wool without severe deterioration in the fibres’ properties. In an energy- and water-consuming process, the hot solution from bio-treatment bath was used successfully in dyeing of wool.

“…In recent years, in view of the urgent need to modernize the textile industry, mainly due to the reduction of production costs and growing international trade concurrency, a large number of studies have been carried out aiming at the applications of ILs into different stages of textile processing (textile spinning, − textile preparation, − textile coloration, ,− textile finishing, − textile wastewater treatment, − and removal of textile dyes). − …”
