Supercritical fluid extraction using carbon dioxide and toluene as co-solvent has also been applied as effective for the extraction of the wool wax comparing with the conventional soxhlet :// During extraction, some fractionation is observed to take place, with some more polar and/or higher molecular weight compounds having a tendency to increase in the later :// The extraction of greasy matter from wool tops was carried out with a continuous extraction technique on a 10 g wool sample with a total extraction time of about 3 hours in a soxhlet :// Using 2% of each enzyme and of water-to-kernel flour ratio, the yield of oil extraction was 38%, estimated in comparison with extraction by Soxhlet :// The reactions of wool with sulfamic acid have been investigated and the results show that under the conditions used, the reactions are similar to those of sulfuric acid and ://   Wool fibres consist of a complex mixture of approximately different proteins (Zahn and Kusch, ), which are composed of 20 amino acids (Rippon, a).Table shows 18 amino acids because asparagine and glutamine are hydrolyzed to the corresponding acids during dissolution of the fibre.

(For "Textile Soaps" see p. )The chemical nature of the surface of wool fibers has been examined by inverse gas chromatography. The C1–C5 linear alcohols were injected into wool‐packed gas chromatography columns and their retention volumes measured.

True adsorption studies could be made because the C2–C5 alcohols were able to be eluted from the wool columns without absorption into the fibers. Decreases in the
