Development of Technology for Production of Sound Insulation Materials from Waste

A technology has been developed for producing sound insulation materials from post-industrial fibrous waste of the textile and light industry. The resulting material, due to the unique arrangement of the fibers and the uniformity of the product, retains the shape and size of the formed plates during operation. The introduction of waste ground cloth edging and waste in the form of regenerated fibers in the composition of the mixtures of samples made it possible to increase their mass, density and stiffness. In order to increase the breaking load along the length of the materials, it was proposed to laminate the developed samples.
