Effect of magnetron sputtering coating time on mechanical property of PET filament

In order to study the effect of magnetron sputtering time on textile material′s tensile property,PET filament fabric was used as substrate to deposit metallic Ti thin film on its surface by varying magnetron sputtering duration,then the tensile property of the treated fabric yarns was tested.The results showed that the sputter coating has limited effect on the warp and weft yarn break tenacity,but greatly changes the break elongation and break work.With the increasing of sputtering time,both the break work and the break elongation change in similar pattern.The break work and break elongation firstly decrease with less sputtering time( 150 s) and then increase with increasing sputtering time.However,when the sputtering time is over 240 s,the break work and break elongation decrease again.
