Prediction of the air permeability of fabrics for institutional use after exposure to light and weather

The effect of natural and artificial light and weather on the air permeability of blended fabrics was compared. An empirical dependence was established for calculating the air permeability of fabrics of different fibre composition; the error of the dependence is a maximum of 7.60%. The possibility of predicting the air permeability of fabrics for institutional use with consideration of the duration of exposure to light and weather was demonstrated. __________ Translated from Khimicheskie Volokna, No. 3, pp. 39–41, May–June, 2007.
