Estudos preliminares sobre a valorização têxtil de penas provindas da indústria da avicultura

Abstract : The poultry industry produces billions tons of chicken, duck, turkey and goose feathers and down feathers worldwide annually. Most of these waste products are incinerated in landfills resulting in pollution of atmosphere and land. For these reasons, it was crucial to develop new ideas for commercial applications of feathers and downs as a fiber byproducts. In this thesis work, feathers and down as fibers were characterized in physical, mechanical, thermal and acoustic scopes and two commercial products were developed using feather and down feathers: nonwoven by dry laid needle punched process and nanofibers nonwovens of keratin by electrospinning process. The results were analyzed using statistical methods to validate the analysis. Thereby, feathers were recycled and used as a raw material for the textile and materials industry. Furthermore, they are easly usable due to their quality, low cost and the available quantity. Moreover, recycled feathers not only reduce the costs of the final product but also create an environmental movement to develop an eco-friendly circular economy.
