- Leathers which made from natural fibers, provide an excellent environment for microorganisms to grow. Currently used in leather industry, antimicrobial agents (biocides) are generally harmful to human health and the environment, therefore their usage has been or shall be restricted or even banned. This study tend to develop the eco-friendly biocide that substitute for toxic chemicals, specifically tested for vegetable tanned leather. Due to their large surface area and ability to retain moisture, vegetable tanned leather has higher opportunity of biodeterioration than other type of tanned leather (e.g. mineral tanning agents). In this experiment, chitosan, a natural biopolymer, was chosen considering its ability to inhibit the bacterial growth. The results showed that chitosan coating in application used impregnation method in drum using 1% (chitosan/leather ratio (w/w), formic acid) during 2 hours was successfully achieved the bacterial growth inhibition.
