Abstract:
The leather goods sector faces ecological issues caused by typical dehairing technique, which requires an environmentally friendly solution. The incorporation of synthetic compounds in the conventional dehairing practice could pose an important contribution to the water pollution. The study analyses enzymatic and conventional treatment, examines at the implications of different enzyme concentration and measures the effluent quality of wastewater. A range of dehairing treatment including conventional, enzyme assisted and single enzyme. The performance of dehairing treatments were observed using

Abstract:
The aim of this work was to demonstrate the effect of dehairing on the content of objectionable fibres and fibre length, in relation to different fleece types of Llama fibre, evaluating the degree of improvement regarding the homogeneity and general textile quality. Sixteen (16) llama fleeces of different fleece types where analysed while being processed by the AM2 dehairing technology. The analysis was implemented regarding fibre groups (FGs) as well as regarding fibre types. The total mean fibre diameter of the dehairing product (TMDnd) of all fleeces of 29.3 µm at the beginning was reduced

Abstract:
A Chemical dehairing process was applied to artificially contaminated bovine hide to evaluate the effect on populations of Escherichia coli O157:H7 and Salmonella Typhimurium, as well as other strains of E. coli, total coliforms, and aerobic plate counts (APC). Pieces of hide (4 cm2) were contaminated with bovine feces inoculated with both rifampicin-resistant E. coli O157:H7 and S. Typhimurium to yield a final count of each pathogen of ca. 5.0 log10 CFU/cm2, or with noninoculated feces which produced an approximate final APC of 6.0 log10 CFU/cm2 and a coliform and E. coli count of 5.0 log10 C

Abstract:
Present research project was conducted to investigate the protease production by gram positive Bacillus species and to investigate their role in dehairing of animal hides. Proteases are widely employed as they have replaced the use of conventional chemical based dehairing methods as they are ecofriendly, easy to cultivate and have high productivity rate. Experimental work was conducted in September, 2022 to July, 2023. 25 agricultural soil samples were collected from different local areas of Haripur and subjected to isolation and purification of Bacillus strains using LB media.

Abstract:
The dehairing process is a fiber cleaning process and consists of separating objectionable coarse fibers and plant and mineral contaminants from the fine fibers as efficiently as possible. This efficiency is determined by the fiber type removal/retention rate (RR) and the fiber length shortening rate (FL). Up the present, in fiber from Llamas and Alpacas, the dehairing yield (R%) has been used as a commercial evaluation of the efficiency of the process. Efficiency is of greater commercial importance because it reflects the amount of desirable fiber that is actually obtained after the cleaning

Abstract:
In leather industries and tanneries, large amount of wastes has been disposed; which polluting water, soil, and atmosphere and causing serious human health problems. In particular, chemical dehairing process of leather industries produces fair amount of toxic wastes. It is, thus, urgently needed to use alternative processes free from pollution. As more than 90% of keratin is contained in feather, it is desirable to develop bioremediation process using keratinolytic microorganisms. In the present investigation, therefore, we first identified Bacillus cereus and Pseudomonas sp. to be able to pro

Abstract:
For an overall description of llama fiber, its fleece structure and differences between fleece types are illustrated schematically, defined through a resumed evaluation, and determined as a compound of different fiber types. A dissection method is described and 252 samples of llama fleeces were dissected forming three fiber groups, within which fine, medium, and coarse fibers are gathered separately and, therefore, a dehairing process is simulated. Taking the group of fine fibers as a reference for the product to be obtained by dehairing, an average dehairing yield of 69% was calculated, which

Abstract:
The art of bookbinding requires not only skills in the old craft of bookbinding but also materials that can transform a simple book into a high-quality artistic product. Due to its unique properties, leather still remains the first-choice material in the case of art and archival bindings. However, the long-term durability of modern leather is not known since there is little commercial interest in long periods of durability and the market of leather for art, design and archival purposes is very small. It is worth noting that deterioration is influenced by the manufacturing technology, and espec
