Keratin waste, including keratin powder, is a significant byproduct of the poultry processing and meat industries. It is a major contributor to waste management problems due to its volume and the environmental pollutants that it can produce. The disposal of keratin waste is challenging due to the potential for odors and pathogens to enter the soil and water. The aim of this work is to present the possibility of using waste materials in accordance with the principles of upcycling and producing fully valuable products. In this research, the author focuses on the production and research of textile multilayer laminates using keratin flour that had been previously considered waste material. New textile composites should be characterized by increased thermal insulation properties with constant comfort in use. This research determines the physiological comfort interpreted as the state of the human-laminate system, which maintains the conditions of comfort in human perception, i.e., constant temperature and humidity of the body under changing conditions of a relative humidity environment.
角蛋白废料，包括角蛋白粉，是家禽加工和肉类行业的一种重要副产品。由于其产量以及可能产生的环境污染物，它是造成废物管理问题的一个主要因素。由于存在气味和病原体进入土壤和水的可能性，角蛋白废料的处理具有挑战性。这项工作的目的是展示根据升级再造原则利用废料并生产具有充分价值产品的可能性。在这项研究中，作者专注于使用先前被视为废料的角蛋白面粉生产和研究纺织多层层压板。新型纺织复合材料应以提高隔热性能且使用舒适度不变为特点。本研究确定了生理舒适度，将其解释为人与层压板系统的状态，即在相对湿度环境变化的条件下，保持人体感知中的舒适条件，即身体的温度和湿度恒定。
