Abstract

Protein based finishing on leather surface is generally done using casein-based formulation which forms a transparent and breathable film. Other naturally available options such as protein extracted from flax seeds exhibit versatile application in various fields. Thus in this work, the flax seed protein which is found to be 84%, along with bees wax emulsion is explored for the first time as an Eco benign binder and as an alternative for casein based finish. The binders play very important role in leather finishing as it helps in binding the various constituents of finishing such as pigments, wax, and additives to the leather matrix. The prepared Eco benign binder formed a continuous film on the surface of the leather and improved the of physical properties and crack resistance of the leather. The FTIR and particle size analysis were carried out for the characterization of the Eco benign binder. The experimental leathers were tested for tensile strength, elongation at break, lastometer test, colour fastness and cold crack tests. The results of the said tests were satisfied and on par with control leathers.

亚麻籽蛋白和蜂蜡乳液混合物对皮革涂饰的影响--一种新型生态良性配方
基于蛋白质的皮革表面涂饰一般使用酪蛋白配方,这种配方能形成一层透明透气的薄膜。从亚麻籽中提取的蛋白质等其他天然物质在不同领域有着广泛的应用。因此,在这项工作中,我们首次将亚麻籽蛋白(含量高达 84%)与蜂蜡乳液一起作为一种环保型粘合剂和酪蛋白涂饰剂的替代品进行了研究。粘合剂在皮革涂饰中起着非常重要的作用,因为它有助于将各种涂饰成分(如颜料、蜡和添加剂)粘合到皮革基体上。所制备的生态良性粘合剂在皮革表面形成了一层连续的薄膜,提高了皮革的物理性能和抗裂性。傅立叶变换红外光谱和粒度分析用于表征生态良性粘合剂。对实验皮革进行了拉伸强度、断裂伸长率、楦度测试、色牢度和冷裂测试。上述测试结果令人满意,与对照皮革相当。
