Development of Enzymatic Processing of Cetyltrimethylammonium Bromide Pre-treated Wool to Achieve Machine Washability

Wool was pre-treated with cetyltrimethylammonium bromide in order to remove surface lipid to make the fibre more hydrophilic to enable more efficient subsequent treatment with the enzyme protease. To ensure protease activity towards the pre-treated wool, residual CTAB had to be removed using an anionic surfactant in acidic conditions. Optimised “delipidised wool was found to promote more efficient treatment with modified protease in terms of improved levels of shrink-resistance to washing with no effect on fibre strength. The method was further optimised to meet commercial machine washability standards. Machine washability was achieved by adding an optimum amount of enteric polymer to native protease in the enzyme treatment of “delipidised wool.
