Abstract
For the purpose of modification of greasy wool in advance of scouring and carbonization respectively, formalization of greasy wool with acidic solutions of hesamethylene tetramine (HMTA) with nonionic surfactant was carried out. The results obtained may be summarized as follows.
(1) Formalization of greasy wool took place even at temperature as low as 35°C, when nonionic surfactant leas added to the HMTA acidic solution.
(2) Greasy wool was remarkahly modified, becoming alkali resistant and at the same time almost degreased, when subjected to formalization with acidic HMTA solution containing nonionic surfactant.
(3) Damages of wool by carbonization with sulfuric acid diminished remarkably when it was subjected to formalization with HMTA before carbonization.
(4) Anionic surfactant showed no marked progress in improving the above mentioned modification results even though used with acidic HMTA solution.
