Abstract
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.

Abstract
The hydrophobic nature of wool induced by its surface lipid barrier hinders its wettability during processing. Scouring of wool is conducted to remove this lipid barrier and facilitate any wet processes. Scouring of wool is conducted using soda ash followed by rinsing with huge amount of water to ensure complete removal of alkali. This work aimed at utilization of thermophilic lipase enzyme for removal of wool surface lipid barrier without deterioration on the fibre interior. A thermally stable lipase enzyme was produced from thermophilic microorganism; namely Bacillus aryabhattai B8W22, and was utilized in bio-scouring of wool. The produced enzyme was immobilized on sericin-based discs to enhance its stability and to make it reusable. The activity of both free and immobilized lipase enzymes at different conditions was assessed. The effects of bio-scouring of wool on its dyeability with acid, basic, and reactive dyes, as well as on some of its inherent properties, were monitored. Results showed that the bio-scoured wool exhibits enhanced dyeability with the said classes of dyes more than that of conventionally scoured samples. One-bath scouring and dyeing of wool fibres in two successive steps was conducted to reduce consumption of water and energy during wet processing of wool.
