METHOD FOR FINISHING TREATMENT OF MOVING TEXTILE MATERIAL

摘要

A method for finishing treatment of a moving textile material includes impregnation of the material with a technological solution containing a precondensate of a thermosetting resin and a catalyst, drying and thermotreatment during which the treatment with infrared radiation is alternated cyclically with the simultaneous effect of the hot air and the static magnetic field. The direction of the magnetic induction vector is oppositely alternated with a pole change frequency of 0.3-3 Hz. The drying of the material is carried out until the residual humidity of 5-6 % is obtained, whereas the stretching of the dried material in the warp direction is maintained within the interval of 7-12 N/m. This allows improvement of the quality of finishing of the material due to the decrease of formaldehyde emission and to the increase of the lustre stability.
