The farmer does very little to ensure that the surface quality of the animal hide/ skin, beyond the usual practices of good farm management and animal welfare care, are improved. There is little incentive, financial or other, for the farmer to invest time and capital in hide/skin improvement. Consequently, global material quality has been declining for the past 20 years. Increasing numbers of surface marks as a result of natural farm influences are seen. The abattoirs can also be a source of surface marks if the operators have poor training and lack experience. Cost cutting in the meat industry will deprioritise investment in training and capital investment that can improve flay quality. In some tanneries, there is also a consistent lack of knowledge and quality control that can help in the prevention of tannery related surface marks. A general de-skilling of the leather-making industry and leather article manufacturing result in higher than normal problems due to the general care, consideration, and skill of the operators.

Tannage Résumé : The leather industry has been fortunate to have one or two of its annual trade fairs during 2021. Machinery manufacturers have not been idle, however, and these trade shows have demonstrated some new technologies in 2021-22. Outside of the tanning industry, there have also been developments that will ultimately make their way into the leather industry. This article will not exhaustively detail all the developments, and manufacturers who have innovated in the past few years who Peel they have not had an acknowledgement of their technology are always encouraged to get in touch with ILM.
