This study intends to investigate the mechanism of scrooping sound of silk . Part 1 describes a method tomeasure the scrooping sound of silk and describes the source of its measured sound . Further, an attempt hasbeen made to clear the source of scrooping sound of silk. The following results are obtained : (1) A generating apparatus of frictional sound has been developed by rubbing two fiber bundles underintersecting at right angles just as violin strings, and an effective frictional sound has been generated . (2) It is able to ignore the influence of the mechanical and outside noise . (3) The measured sound is intermittent, and it is related to stick-slip vibration of friction . (4) The intermittent vibration contains sounds of string transverse vibration and vibration sounds ofabout 8 KHz frcquency whose source is now unknown. (5) The scrooping sound of silk also contains an intermittent vibration which is almost about 8 KHzin frequency.
