The article is devoted to the regeneration of fibers from garment waste, i.e. from cuttings and flaps, which are secondary raw materials. The influence of the cylinder diameters of the feeder of the fiber recovery machine and their rotation frequency on the properties of the recovered fiber, that is, the fiber yield, the residual fiber content and the degree of fiber shortening, has been studied. The output parameters are the amount of waste to be separated, the proportion of unreported and scraps of thread, as well as the shortening of the fiber length. Experiments on the matrix of a rotatable central compositional experiment were carried out and the corresponding regression equations were obtained. As a result of their solution, the best options were found. As a result of the experiments, the values of the factors providing the best indicators of the properties of the fiber were determined, and, accordingly, the possibility of obtaining a high-quality reconstituted fiber was proved. The properties of yarn obtained using reduced fibers as a component in a mixture have been studied.
