Embodiment 1
[0016] A kind of antibacterial anti-shrinkage finishing technology of wool fabric, described technology comprises the following steps:
[0017] (1) The wool fabric is placed in a 16% aqueous solution of sodium hydroxide, and carried out an alkalization reaction at room temperature for 1.5 hours. After the reaction, adding a volume fraction of 4% hydrochloric acid neutralizes the residual sodium hydroxide , repeatedly washed with deionized water, and dried naturally;
[0018] (2) Immerse the wool fabric treated in step (1) in the finishing solution A, the bath ratio of the fabric and the finishing solution A is 1:25, the reaction temperature is 25°C, the pH is 8.0, and the reaction time is 30min. Rinse with deionized water and dry at 80°C;
[0019] (3) Soak the wool fabric finished in step (2) in the finishing solution B, the bath ratio of the fabric to the finishing solution B is 1:40, the reaction temperature is 40°C, the reaction time is 25min, and immediately put it in an ...
