Wool dissolution based on reduction method and characterization of its effect

For better characterization of wool dissolution based on reduction method,a reduction method which has a higher dissolution rate was chosen to dissolute wool fiber in neutral dissolving liquid.The dissolved products were analyzed and measured,and the dissolution effect was characterized.The results showed that the solvent mainly acts on wool cortical cells;the higher the concentration of urea,the better the swelling effect of keratin,and the higher the dissolution rate.The wool dissolution rate is markedly improved with(0.5 g SDS)/(g wool)and 5% of β-mercaptoethanol;the dissolution is also significantly impacted by temperature,the wool dissolution rate increases with temperature,but extra high temperature will result in damage and degradation of keratinocytes macromolecules.
