Abstract: In order to solve the problem of raw silk tension testing,this paper presented a measuring method of raw silk tension using acoustic principle.When the sound wave which is produced by sound generator transmitting through raw silk with some tension form one end to the other,the output amplitude received by sound receiver at the other end was measured,and the relationships between the raw silk tension and acoustical attenuation was examined.The experimental result indicates that when the tension of raw silk increases gradually,the intensity of sound transmitting through it rises.Therefore,the raw silk tension can be determined by the sound intensity signal sent out by the sound receiver.
