For carrying-out the work the plant for obtaining from liquid melt of chip polyolefin (polyethylene, polypropylene), polyamide and polyethylene terephthalate yarns with their subsequent stretching is used. The plant is designs according by of the Federal target scientific and technical program " Researches and development in priority directions of science and engineering" in 2002-2003 г.г.
Results of researches:
With a view of improvement of qualitative characteristics of polyester materials the influence of polyethylene terephthalate on the oligomers is studied,  their percentage and inclusion in a textile material substantially effects properties, water, water solutions of ammonia and  some salts of ammonium at the temperatures exceeding 100 C. The essence of physical and chemical processes in which participate oligomers in dyeing and finishing of polyester textile materials according high-temperature periodic technologies is discovered.
The regularity of processes of oligomers migration from internal areas of a polymeric material outside and hydrolysis superficially localized oligomers are establish. While applying them it is possible to influence directly intensity of each of them. The new method of the directed change of some properties of the polyester textile materials is proved. It is consisting in regulation of a course the given physical and chemical processes with participation of oligomers. It was shown that regulation can be carried out by means of a variation of parameters of processing of a fibre the diluted water solutions of ammonia, salts of ammonium or compositions on their basis, changing it concentration of cyclic oligomers in the bulk of a polyester fibrous material and, mainly, on its surface.
The plant includes two stands: 
1 - obtains of yarns from liquid melt, 
2 - stretching and twisting of yarns. 
The maximal capacity of the plant - 5 kg. 
The maximal productivity of the plant - 20 kg per day. 
Two-band of yarns stretching, repetition factor - up to 10.
