The consumption of white meat is extremely widespread worldwide. Poultry (chicken, turkey e.t.c) and geese, ducks play an important role in meeting this demand. Worldwide, production of geese includes the production of goose meat, goose liver and goose feathers. However, in our country, the production of geese is mainly for goose meat, with a small quantity also produced for eggs. If all products produced from geese, including the by-product goose feathers, are subjected to a production process meeting technical and standard requirements, each product can be expected to provide a high level of added value. In this perspective, it is considered to be a very profitable business. The feathers of the goose, which are the main subject of our study, stand out as an important material because of their softness, lightness and superior thermal insulating properties. In recent years, as it was recognised that goose feathers could be turned into valuable value added, new holdings were opened in various regions for the production of feathers. It is noted that these producers also wish to produce geese for the production of feathers. In this study, the downy and back feathers, which are by-products of the production of goosemeat, were washed in two washing programmes to clean them and prepare them for further production of a sanitary product. Various chemical and auxiliaries were used in the washing process. After bleaching and rinsing, the dried fibre was assessed for odour and purity in order to establish the most suitable composition. Therefore, a washing formula coded Y1 was found to provide the best results and is recommended for future washing operations.
