In the paper, the methods of reused yarn processing are analyzed, considering the issue of maintenance reliability of the proposed auxiliary equipment for garment and knitting production waste processing. The estimation of implementation possibility is given for the developed technology by means of introduction of oiling device at the stage of yarn winding on a spool after backwinding on auxiliary equipment that will allow reducing the treated yarn’s fluffiness and removing its glassy state giving elasticity.

In the paper the analysis of technologies for processing of wastes of sewing and knitted production is carried out. Issues of development of ecologically expedient methods and devices for processing of wastes of sewing and knitted production are considered. Approbation of the developed universal auxiliary equipment for processing of wastes from sewing and knitting production has been carried out. The effect of humidity and temperature on the physical and mechanical properties of recycled yarn fibers has been studied. The estimation of the possibility of implementing the developed technology with the mathematical modeling is given.

The article investigates the sources of sewing and knitting production waste, analysis types and characteristics of knitted waste, the current state of waste treatment technologies and their impact on the environment. It is proved that the technological production processes are accompanied by intense release of harmful substances that contaminate the work area and the environment, causing deterioration of working conditions for people and equipment. On the basis of technology analysis of recycling sewing and knitting production waste was designed and presented a model for the processing of knitting yarn waste.
