Considerations Regarding the ESD Type Textile Waste Recovery

The Textile and Clothing Industry affects the environment through the use in the manufacturing process of very large quantities of water, energy and chemicals. This Industry generates a lot of waste, due to the use of a very large number of chemicals and technological processes. Waste generation implies a loss of materials and energy and imposes high environmental and economic costs to society for their collecting, treatment and processing. A permanent activity of finding technological solutions for the textile waste processing is also supported by the implementation in the economic and social life of multifunctional and adaptive textile systems for whose manufacturing smart elements are used. The work presents aspects on textile waste preliminary processing in the form of knitted bilayer textile structures containing conductive yarns. During the garments manufacturing have resulted textile waste. For these waste were conducted technological experiments of preliminary processing. This processing of the textile waste as yarns, trimmings from knitted fabrics, trimmings from woven fabrics includes the following operations: sorting depends on base colors, cutting, opening. The opening process can be characterized by: opening efficiency; unopened yarns percentage; unopened patches percentage; the average length of recovered fibers. In order to assess the fibers structures aspect, has been used the electron microscopy by analyzing their longitudinal and cross section images.
