Abstract The biodegradability of polylactic acid(PLA) fabrics was evaluated by two methods:
enzyme and soil degradation. Three different enzymes were selected to evaluate.
Degradation times were measured at optimal enzyme treatment conditions. Biodegradation
by enzymatic hydrolysis was compared with soil degradation. As a result, biodegradation
created cracks on the fiber surface, which led to fiber thickening and shortening. In addition,
new peak was observed at 18.5°by degradation. Moreover, cracks indicating biofragmentation
were confirmed by enzyme and soil degradation. By enzyme and soil degradation,
the weight loss of PLA fabrics was occurred, there through, the tensile strength decreased
about 25% by enzyme hydrolysis when 21 days after, and 21.67% by soil degradation
when 60 days after. Furthermore, the biodegradability of PLA fabrics by enzymatic and soil
degradation was investigated and enzymatic degradation was found to be superior to soil
degradation of PLA fabrics. Among the three enzymes evaluated for enzymatic degradation,
alcalase was the most efficient enzymes. This study established the mechanism of biodegradation
of PLA nonwovens, which might prove useful in the textile industry. |
