FIELD: sewing industry, in particular, processes for moisture-thermal treatment of sewing articles.
SUBSTANCE: method involves pressing semi-finished article located on working tool after fabric fibers are converted to highly-elastic state; thereafter, controlling and maintaining at predetermined level fabric temperature and condensate density by means of low inertia thermal pairs such as Chromel Copel 0.2. Mechanical pressure of working tools includes three periods: loading, holding under loading and relieve, with values thereof being measured by means of known tension resistors. Thermal- physical and physical-mechanical processes are controlled and regulated by means of automatic control system in accordance with special program regulating optimal maximum values of parameters under measurement. Duration of each period, as well as numerical values of specific pressure are automatically compared in time with values calculated by control system and corrected, with process character and fabric density being taken into consideration. Data delivered from sensors (thermal pairs and tension resistors) is calculated (mathematically processed) and compared with process basic values for further optimization and generation of signals for continuation or termination of process.
EFFECT: optimized and fully automatized pressing process and thereby improved quality of sewing articles, and increased efficiency by eliminating additional manual moisture and thermal treatment operations.
