Conclusions

Analysis of the reasons for dissipation of ultrasonic wave energy in bulk-looped acetatepolyamide yarns has made it possible to establish the following:

ultrasonic waves are propagated only along the cone (principal) polyamide yarn; there-upon an anomalously large damping of ultrasound is observed as compared with damping in smooth yarns;

scattering of ultrasonic energy is determined by the character of the interaction between the principal fibre and the fill-in fibre.
