The investigations show ed that w ith increasing of the temperature the tenacity of SAF decreased and elongat ion increased gradually. T emperature had little influence on friction properties of SAF. The tenacity of SAF decreased and frict ional coefficient increased rapidly w ith increasing of relative humidity value. Key words SAF; thermohydro properties; frict ion; tenacity; elongation ( super absorbent f iber SAF ) SAF [ 1- 5] 1 SAF
