1. Способ переработки бытовых и технологических отходов полиэтилентерефталата (ПЭТФ) в волокнистые изделия, включающий очистку отходов, их измельчение, сушку, подготовку расплава, экструдирование его через фильеру волокнообразующей головки с последующим вытягиванием и утонением сформированного волокна закрученным по спирали высокоскоростным газовым потоком, подаваемым под давлением в направлении экструдируемого материала и нанесением волокон на поверхность формообразователя, или сбора волокон с образованием полимерной ваты, отличающийся тем, что измельченные отходы ПЭТФ подаются в цилиндр экструзионного генератора волокон при температуре выше температуры стеклования ПЭТФ, температура вытягивающего волокно газового потока на выходе из волокнообразующей головки 190 - 350oС, а его давление не менее 1,5•104 Па.1. A method of processing household and technological wastes of polyethylene terephthalate (PET) into fibrous products, including waste treatment, grinding, drying, melt preparation, extruding it through a die of a fiber-forming head, followed by stretching and thinning of the formed fiber by a spiral-wound high-speed gas stream supplied under pressure in the direction of the extrudable material and applying fibers to the surface of the former, or collecting fibers with the formation of polymer wool, excellent yuschiysya in that the shredded waste fed into the cylinder PET melt generator fibers at a temperature above the glass transition temperature of the PET fiber pulling temperature of the gas stream leaving the fiber-forming heads 190 - 350 o C and the pressure at least 1,5 • 10 4 Pa. 2. Способ по п. 1, отличающий тем, что в измельченные отходы ПЭТФ вводят до 2% кристаллизующих добавок, например, минеральных наполнителей. 2. The method according to p. 1, characterized in that up to 2% of crystallizing additives, for example, mineral fillers, are introduced into the ground PET waste.
