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

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ultrasonic wool scouring has the potential to replace the traditional method using detergents and other additives. This study aims to investigate the effect of important parameters of an ultrasonic bath operating at 38 kHz frequency on the possible chemical modification of wool scoured in tap water without any additives on a laboratory scale. The parameters tested were bath temperature (20-40-60) °C, scouring time (10-20-30) min and ultrasound intensity (30-60-90) % power of 350 VA. The measured characteristics were the content of basic groups (obtained in the range of 7.9-8.5 mmol/g) and acidic groups (obtained in the range of 9.9-8.9 mmol/g) formed on the wool as well as the ability to remove zinc salt from the solution by adsorption (97-86 %). ANOVA analysis of basic and acidic group dispersion showed the dominant effect of temperature in contrast to scouring time and intensity (F = 88.495; p < 0.001 for basic group and F = 73.101; p < 0.001 for acidic groups). The Zn(II) removal was statistically significantly affected by temperature (F = 17.652; p < 0.001) and scouring time (F = 4.913; p = 0.011), while the effect of ultrasound intensity was at the threshold limit of significance. The smallest chemical changes in the fiber occur at the bath temperature of 20 °C, scouring time of 10 min and intensity of 90 %.
