Microbiological Properties

Because of high lignin content, kapok fiber is not easily attacked by ordinary cellulolytic bacteria (Nilsson and Bjordal 2008) and shows better antibacterial prop­erty (Han 2010). Liu et al. (2007) investigated the anti-moth, anti-mite, and antibac­terial properties of kapok battings. The results of anti-moth test showed that the mean value of weight loss of kapok batting was smaller than reference sample obvi­ously, and the damage grade of surface of kapok batting was 2A. In the anti-mite test, the mite expelling rate was 87.54 %, which proved the anti-mite property of kapok batting. For antibacterial test, kapok batting was confirmed to possess both the bactericidal effect and bacteriostatic effect on Escherichia coli. But in contrast, it did not have these effects on Staphylococcus aureus.
