How can ultrasonic scouring of sheep's wool chemically modify its surface?

In contrast to the acidic groups, however, the interactions of temperature and time (F = 3.712; p = 0.010) and temperature and intensity (F = 3.175; p = 0.020) were statistically significant, while the interaction of time and intensity was marginally significant (F = 2.256; p = 0.075) and the triple interaction did not reach significance (F = 1.078; p = 0.392).

The number of basic groups confirmed a significant effect of temperature (F = 88.495; p < 0.001), while scouring time (F = 0.460; p = 0.634) and ultrasound intensity (F = 2.434; p = 0.097) did not reach statistical significance on their own.
