“…Results in Table 6 reveal also the bending length of wool fabric treated with protease/PAS system is lower than that of the biotreated or PAS-treated fabrics, and each of the latter has lower bending length than the untreated sample. Whereas the removal of the rigid cystine-rich scales of bio-treated wool might be the reason of the decrease in the bending length [30]; the softening action imparted to wool fabric by application of PAS may rationalize the reduced bending length of the PAS-treated fabric [31]. These results are in harmony with the drape coe cient values of the treated sample (c.f.…”

Production of textile garments with pleasant aesthetic property is always a customer-demand; and the application of eco-friendlier methods to attain this target is driven by the environmental legislation all over the world. The main aim of this study is improving garment appearance and performance attributes of wool fabric by two-consecutive benign processes using bio-and chemical treatments. Two commercial proteases were used in bio-treatment of wool under their respective appropriate conditions. The biotreated wool fabrics were modi ed with an aqueous solution of a water-dispersible cationic softener based on poly amino siloxane (PAS). The effects of these treatments on some of the physical and mechanical properties of wool fabric were investigated. Scanning electron microscopy (SEM) shows the descaled surface of bio-treated wool, and the coated bre surface of AS-treated wool. Results of this investigation showed that the drapability, and hence the aesthetic property, of the treated fabric was improved. Based on the bending length, drape coe cient, wettability, smoothness, yellowness index, and AC electrical conductivity of the treated wool fabrics, selected samples were assigned to be used in prediction of the garment appearance using CLO3D simulation software.

“…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.

“…The said biopolymer composite with PA6 was adopted to remove methylene blue (cationic colorant) and an acid dye from a dye effluent (anionic dye). Cationic dyes are widely used in coloration of acrylic fabrics (El-Gabry et al, 2016) and the anionic dyes are the most commonly used class of dyes for coloration of proteinic fabrics (El-Sayed, 2006;Kantouch et al, 2011).…”

The main objective of this work is the preparation of nano-fibrous mats (NFM) from polyamide 6 (PA6) reinforced and functionalized by renewable proteinic waste and examining their potential use for the sorption of heavy metal ions and dyes from wastewater from textile plants. Two renewable waste biopolymers; namely keratin (from waste of wool combing) and sericin (from degumming of natural silk) were extracted and regenerated. NFM were prepared by electro-spinning of PA6/ biopolymer composites in formic acid using nozzle-less electro-spinneret. The potential of the prepared mats for sorption of Cr+6, Cr+3, Cu+2, and Pb+2 cations as well as anionic and cationic dyes from wastewater was assessed. The prepared composites were characterized by measuring their viscosity, nano-fibre diameter, pore size, thickness, and air permeability. The morphological structure of the electro-spun NFM was investigated by scanning electron Microscopy. Chemical and physical properties of the obtained mat were studied FTIR, TGA, DSC, and XRD. The capacity of the prepared NFM for sorption of cations and dyes depended on the mat composition and the nature of the adsorbed cation or dye. This work meets some environmental and economic demand by extraction of keratin and sericin from waste materials and their utilization in reinforcement of PA6 NFM for sorption of selected cations as well as dyes from textile effluents.
