By the flowing-out method-a single operation which does not press positively-the author has measured, as a fundamental analysis with 14 kinds of solvent and greasy wool, the required time tf (sec) for the first flowing-out, the quantity Qf (cc/sec) of flowing-out liquor per unit time the solvent ratio αf, the quantity Yf (g) of solid yolk removed, the residual suint value sRf (%), the residual grease value gRf (%) and the residual yolk value yRf (%)-and observed how far they vary with the kind of solvents. The wool samples were Merino-type, greasy, grade 64' S, with a yolk content of 25.28±1.26% (suint 7.72±0.36%, grease 17.56±0.90%, shown by a 95% degree of confidence).
The author concludes in this article that:
(1) Each residual yolk value of sample wool assembly treated by Acetone, Methyl Ethyl Ketone and Anon was extremely large.
(2) Synthetic solvents are synthetically more suitable than petroleum solvents for the flowing-out method.
(3) The mechanical removing action for yolk acts effectively in the flowing-out method.
