Investigation of the influence of the UV-radiation on the strength properties of the PP-threads

The results of the investigation of the influence of the UV-radiation on the strength properties of PP-threads are represented in this article. The mathematical model of interconnection of the accumulation level of the structure damages of the PP-threads and the UV-radiation influence period is developed. The practical utilization of the given functional dependence allowed making the test conditions more precise to carry out a comparative analysis of the PP-threads taking into account the UV-threads radiation influence on the strength properties.
