Anti-bacterial finishing of wool fabric via immobilized lactoferrin with MTG

In view of wool fabric anti-bacterial finish,a new biological cross-linker MTG(transglutam inase)was used to catalyze the immobilization of lactoferrin onto the wool fabric and the antibacterial properties of the enzyme treated wool fabric were tested.The lactoferrin immobilization efficiency was determ ined by UV spectrophotometry.Major parameters in immobilization process were d iscussed.The optimum cond itions were as follows: 30 U /g wool fabric ofMTG,40℃of temperature,2 h of reactive time,5 mg/mL of lactoferrin.Under the cond itions,the lactoferrin immobilization efficiency on wool fabrics was about 9%,the inhibition rate to staphyllo-COCCUS aureus reached 57.95% and the treated fabric exhibited good antibacterial property.
