Abstract: In order to have a better understanding of the polylactic acid(PLA) fabric wearability and enhance the research and development level of this kind of products,the paper discusses the test of fabric properties such as the strength and elongation,air permeability,wrinkle recovery,moisture transmitting,draping, abrasion resistance,pilling and weaving resistance of pure PLA fabric,the blend fabric in a blend ratio of PLA fiber/cotton(80/20),cotton fabric and polyester fabric with similar specifications.The result shows that the polylactic acid fabric has good elongation,wrinkle recovery,moisture transmitting,draping property and abrasion resistance.Its air permeability and anti-pilling property are not as good as those of cotton fabrics.It has higher weaving resistance and will prevent the fabric slippage.Due to addition of cotton fibers,the air permeability and anti-pilling property of the blended fabric are improved,weaving resistance is brought down,but wrinkle recovery,draping property and abrasion resistance drop.
