Application of Coupling Agent Modified Chitosan Antibacterial Agent in Flax
Due to the poor solubility of chitosan in water,its application is limited.Using silane coupling agent to modify chi-tosan and applying the optimized modified product to linen fabric;test and characterize whether the finishing agent can success-fully treat linen fabric through thermal performance,scanning electron microscopy,and other analysis.The test results showed that the optimal finishing process was optimized through orthogonal experiments,with a bath ratio of 1∶30,a reaction time of 100 minutes,a reaction temperature of 45 ℃,and a finishing agent dosage of 30％(owf.).Under these conditions,the product had the best antibacterial effect on Staphylococcus aureus and Escherichia coli,with inhibition rates of 99.76％and 100％,respectively.
